No.  1  —  Revision  of  the  Chinese  Mecoptera 
By  Fung  Yinq  Cheng 

INTRODUCTION 

The  Mecoptera,  commonly  called  scorpion  flies  and  hanging 
flies,  are  widely  distributed  over  the  Northern  Hemisphere  and 
are  well  represented  in  China.  However,  little  collecting  of 
these  insects  has  actually  been  done  in  China,  especially  in 
the  interior  regions.  It  was  my  good  fortune  to  be  a  member  of 
the  entomological  expedition  of  the  Sino-British  Committee, 
extending  from  June  1939  to  July  1940;  this  was  mainly  re- 
stricted to  Szechwan,  Sikang  and  Shensi  Provinces.  The  present 
study  is  based  largely  on  specimens  collected  on  this  expedition. 
Since  I  have  been  able  to  examine  type  specimens  in  the  Museum 
of  Comparative  Zoology,  the  U.  S.  National  Museum  and  the 
Heude  Museum,  and  also  material  in  the  Museum  of  the  Institute 
of  Zoology,  Academia  Sinica,  Museum  of  Foochow  University, 
Chou  Collection,  Issiki  Collection  and  Maa  Collection,  I  have 
included  an  account  of  all  species  described  from  China. 

I  wish  to  express  my  sincere  thanks  to  all  the  curators  of 
these  museums  and  the  owners  of  private  collections  for  the 
loan  and  gift  of  material  and  for  their  kind  cooperation  which 
has  made  this  study  possible :  Dr.  P.  J.  Darlington,  Dr.  J.  C. 
Bequaert,  Museum  of  Comparative  Zoology;  Dr.  A.  B.  Gurney, 
U.  S.  National  Museum ;  Dr.  Sieien  H.  Chen,  Academia  Sinica ; 
Father  de  Cooman,  Heude  Museum ;  Dr.  Hsiu  Fu  Chao,  Na- 
tional Foochow  University ;  Dr.  Chou,  Chang-chia-kang ;  Dr.  S. 
Issiki,  Tokyo  and  Mr.  Maa,  Taipeh. 

Furthermore,  I  am  deeply  indebted  to  Professor  F.  M.  Car- 
penter of  Harvard  University  for  his  encouragement  during 
the  course  of  my  study  and  for  his  kindness  in  reading  over 
this  paper. 

HISTORICAL  ACCOUNT 

The  order  Mecoptera  comprises  about  three  hundred  and 
thirty  described  species  from  the  entire  world.  Until  recently, 
only  a  few  of  them  were  known  from  China.    In  1921,  Esben- 


BULLETIN:    MUSEUM   OF   COMPARATIVE  ZOOLOGY 

Petersen  recorded  only  eight  species  from  there  in  his  mono- 
graphic revision  of  the  order.  hi  1037,  Wu  reported  nineteen 
species  in  his  "Catalogus  Insectorum  Sinensium,"  fifteen  species 
belonging  to  Panorpidae  and  four  species  to  Bittacidae.  In  1938, 
Carpenter  listed  twenty-eight  species  of  Panorpidae.  In  the  past 
ten  years,  more  new  species  have  been  described  by  Carpenter, 
Tjeder  and  myself.  The  number  of  described  species  has  thus 
been  brought  to  fifty-seven.  In  the  various  collections  which  I 
have  examined  recently,  twenty-five  additional  species  have  been 
found,  bringing  the  total  number  of  known  Chinese  species  to 
eighty-two. 

Because  of  its  geographical  nature,  the  mainland  of  China 
has  been  separated  into  thirty  provinces.  Scorpion  flies  and 
hanging  flies  occur  in  all  those  (about  half)  to  which  expeditions 
have  been  made.  Since  previous  expeditions  did  not  include  most 
of  the  mountainous  areas  of  any  of  the  provinces  and  no  expedi- 
tions at  all  have  been  made  for  Mecoptera  in  fifteen  of  the  pro- 
vinces, I  believe  our  collections  and  knowledge  of  this  order  in 
China  are  still  very  incomplete. 

SYSTEMATIC  ACCOUNT 

Of  the  five  existing  families  of  Mecoptera,  only  two  have  been 
found  in  China.    They  can  be  recognized  as  follows : 

Tarsi  with  two  claws,  not  raptorial Panorpidae 

Tarsi  with  a  single  claw,  modified  for  raptorial.  .  .  .Bittacidae 

Family  PANORPIDAE

1931,  Bull.  Mus.  Conip.  Zool.,  72(6):   209. 
Ocelli  present;  labial  palpi  two-segmented;  abdomen  cylin- 
drical or  nearly  so,  tapering  to  a  point  in  the  female,  without 
ovipositor ;  6th  to  8th  abdominal  segments  of  male  narrowly  cylin- 
drical, apical  segment  modified,  usually  enlarged ;  tarsi  with  two 
(daws,  not  modified  for  grasping ;  wings  more  or  less  slender, 
with  primitive  venation ;  costal  space  narrow,  with  few  cross- 
veins  ;  Pts  originating  at  about  one-third  of  wing  length  from 
base ;  M  dividing  near  the  middle  of  wing.

Three  of  the  six  existing  genera  of  the  family  inhabit  China, 
namely,  Panorpa,  Neopanorpa  and  Leptopanorpa;  the  fourth 
genus,  Panorpodcs  occurs  in  Japan,  the  fifth  Apteropanorpa  in 
Tasmania,  and  the  sixth,  Brachypanorpa  in  North  America.  Both

Panorpa  and  Neopanorpa  were  found  in  most  of  the  Chinese  pro- 
vinces where  expeditions  have  been  made.  Leptopanorpa  is  repre- 
sented by  a  single  species  found  in  Hainan,  Kwangtung.  As  a 
matter  of  fact,  however,  the  latter  locality  is  an  island,  separated 
from  the  mainland  bv  the  sea.    The  three  genera  occurring  in

Rostrum  long  and  slender;  tarsal  claws  serrated  on  inner 
margins;  wings  are  fully  developed,  rather  broad,  1A  long,  ex- 
tending to  the  anal  margin  of  wing  beyond  origin  of  the  radial 
sector;  abdomen  in  both  sexes  not  longer  than  the  wings.  6th

genital  bulb  of  male  not  pedunculate  basally. 
Genotype:  Panorpa  communis  Linne. 

This  is  the  largest  genus  of  Mecoptera,  including  one  hundred 
and  sixty-two  known  species  in  the  whole  world.  Thirty  species 
have  been  already  recorded  in  China  and  ten  new  ones  are  de- 
scribed below,  making  a  total  of  forty.  They  are  distributed 
throughout  eleven  provinces.  As  suggested  by  Carpenter  (1938), 
these  species  can  be  conveniently  divided  into  three  groups,  de-

pending  upon  the  structure  of  the  6th  abdominal  segment  of 
the  male  —  that  is,  whether  the  anal  horn  is  present,  absent,  or 
represented  by  two  similar  processes.  In  the  first  or  diceras 
group,  with  double  anal  horn,  belong  diceras  McLachlan,  tjederi 
Carpenter,  stotzneri  Esben-Petersen  and  kimminsi  Carpenter ;  in 
the  second  or  centralis  group,  with  a  single  anal  horn,  belong 
centralis  Tjeder,  flavipennis  Carpenter,  emarginata  Cheng  and 
obtusa  Cheng;  in  the  third  or  davidi  group,  without  anal  horn, 
belong  davidi  Navas,  stigmalis  Navas,  waongkehzengi  Navas, 
difficilis  Carpenter,  fructa  Cheng,  cladocerca  Navas,  trifasciata

the  female,  so  that  their  position  in  the  above  grouping  is  not 
determinable. 

Other  characteristics  which  have  been  used  under  each  group 
of  Panorpa  are  the  wing  markings  and  the  general  aspect  of 
both  male  and  female  genitalia.  The  former  characteristic  some- 
times appears  to  be  similar  from  one  species  to  another  and  in 
some  cases  passes  through  a  little  range  of  variation,  while 
the  latter  remain  perfectly  stable  even  in  minute  details.  In 
identification,  therefore,  I  use  the  wing  markings  to  assist  in 
the  first  determination  of  the  species  and  then  the  characteristics 
of  both  male  and  female  genitalia  for  the  final  decision. 


b  BULLETIN  :   MUSEUM  OF  COMPARATIVE  ZOOLOGY 

In  the  wings  of  Panorpa,  the  color  of  the  membrane  is  a  con- 
venient feature  for  general  classification.  In  some  species,  the 
wings  are  clear  and  colorless  (kimminsi,  fig.  271),  in  others  they 
are  distinctly  yellow  (flavipennis),  and  in  some  others,  they  are 
faintly  yellow  (aurea,  fig.  281).  The  markings  of  the  wings  are 
readily  grouped  into  several  categories,  depending  upon  how 
heavy  the  markings  are.    In  some  species,  in  which  the  wing  is 


Fig.  4.     Male  abdominal  segments  of  Neopanorpa  tienmushana  n.  sp. 

heavily  marked  (japonica,  fig.  286),  there  are  three  transverse 
bands  and  two  spots :  these  are  designated  the  pterostigmal  band, 
the  basal  band,  the  apical  band,  the  basal  spot  and  the  marginal 
spot  (text-fig.  1).  In  other  species  the  wing  is  lightly  marked, 
the  bands  are  very  narrow,  the  basal  spot  and  the  marginal  spot 
are  usually  absent,  and  sometimes  both  pterostigmal  and  apical 


Fig.  5.    Male  abdominal  segments  of  Leptopanorpa  javanica  (Westwood). 


CHENG:  REVISION  OF  THE  CHINESE  MECOPTERA  7 

bands  are  interrupted  or  incomplete  (seniifasciata,  fig.  274).  In 
some  other  species,  no  markings  are  present,  except  for  a  slight 
suspicion  of  shadow  at  the  wing  apex  (obtusa,  fig.  272) .  Curiously 
enough,  all  species  bearing  the  anal  horn  belong  to  the  latter 
category,  the  only  exception  being  flavipennis,  which  has  a  dis- 
tinctly yellow  wing  membrane  and  ver}r  narrow  basal,  pterostig- 
mal  and  apical  bands.  It  is  interesting  to  note  that  the  single 
anal  horn  of  this  species  is  exceptionally  short  (fig.  13),  quite 
different  from  the  other  single  or  double  horn  species.  As  worked 
out  by  Carpenter  in  his  "Revision  of  the  Nearctic  Mecoptera'' 
(1931),  the  venational  characteristics  of  Panorpa  are  purely 
individualistic  and  could  not  be  used  for  the  classification  of  the 
species.  The  same  statement  applies  to  all  the  Chinese  Panorpa 
from  Pukien  —  the  only  locality  from  which  sufficient  specimens 
have  been  collected  to  allow  a  conclusion. 

The  male  genital  segment  (or  9th  segment),  modified  into  a 
bulb,  consists  of  an  upper  tergite  (preepiproct),  a  lower  sternite 
(hypandrium)  and  a  pair  of  two-segmented  structures  in  be- 
tween, the  basal  U-shaped  coxopodites  and  the  distal  hooked 
harpagones.  In  some  species  there  is  a  papilla  at  the  inner  distal 
margin  of  each  of  the  coxopodites  (carva,  fig.  52,  davidi,  fig.  57). 
and  in  others  a  number  of  black  spines  at  the  same  place  (sex- 
spinosa,  fig.  87,  centralis,  fig.  10).  The  harpagones  vary  much 
in  shape  and  degree  of  development;  in  most  species  there  is  a 
concave  area  on  the  inner  basal  surface  of  each  harpagone  (cen- 
tralis, fig.  10,  davidi,  fig.  57).  In  others,  instead  of  a  concave 
area,  there  is  an  expansion  or  lobe  at  the  same  place.  This  lobe 
may  be  very  small  (japonica,  fig.  90),  greatly  enlarged  (baoh- 
washana  n.  sp.,  fig.  83),  or  tooth-shaped  (diceras,  fig.  7),  or  it 
may  arise  at  a  different  level  (trifasciata  n.  sp.,  fig.  49,  cheni  n. 
sp.,  fig.  86).  The  preepiproct  is  visible  as  a  single  external  ap- 
pendage from  a  dorsal  aspect  of  the  bulb.  In  most  of  the  species, 
it  has  a  pair  of  distal  lobes  (diceras  etc.,  fig.  2),  but  in  waong- 
kehzengi,  the  lobes  are  so  inconspicuous  that  the  apex  of  the 
preepiproct  appears  only  slightly  emarginated  (fig.  43),  and  in 
japonica,  no  lobes  occur  at  all,  the  preepiproct  terminating  as 
a  rounded  posterior  margin  (fig.  85).  The  hypandrium  appears 
as  a  basal  plate  from  a  ventral  view  of  the  bulb ;  this  is  usually 
produced  into  two  long  lobes,  the  hypovalvae.    In  some  species 


8  BULLETIN  :   MUSEUM  OF  COMPARATIVE  ZOOLOGY 

the  hypandrium  is  long  and  stalk-like  {japonica,  fig.  90,  stigmalis, 
fig.  33)  ;  in  many  others,  it  is  inconspicuous  {emarginata  etc., 
fig.  31).  The  hypovalvae  are  generally  slender  and  flattened 
{flavipennis,  fig.  11),  while  in  baohwashana  n.  sp.,  they  are 
broadened  towards  the  apex  with  upwardly  folded  outer  margins 
(fig.  83).  In  the  interior  of  the  bulb,  between  the  bases  of  the 
coxopodites  arises  an  irregular  aedeagus  from  the  wall  of  the 
genital  pouch.  This  usually  has  a  pair  of  prominent  apical  proc- 
esses and  a  pair  of  lateral  processes.  In  some  species,  the  apical 
processes  are  very  short  and  inconspicuous  {tjederi,  fig.  6)  ;  in 
others,  they  are  very  long  {curva,  fig.  52),  and  in  some  others 
they  have  greatly  enlarged  distal  ends   {difficilis,  fig.  46).    At

the  sides  of  aedeagus  are  two  slender  parameres  supported  on 
a  U-shaped  bar  in  the  ventral  wall  of  the  genital  chamber  proxi- 
mal to  the  base  of  the  aedeagus.  The  parameres  exhibit  a  re- 
markable series  of  modifications  in  different  species.  They  are 
strongly  sclerotized  and  very  stiff,  usually  blackish  brown  in 
color  and  with  a  cluster  of  spines,  resembling  the  barbs  in  a 
bird's  feather,  on  their  inner  margins  and  their  distal  ends.  In 
some  species  the  parameres  are  reduced  to  a  very  minute  linear 
thread  without  spine  {japonica,  fig.  90),  while  in  most  others 
they  are  long  with  prominent  barbs  {centralis  group,  fig.  10, 
davidi  etc.,  fig.  57).  In  some  species,  they  are  Y-shaped  {aurea 
n.  sp.,  fig.  62),  in  others  they  have  3-4  branches  {diceras  group, 
fig.  7).  Curiously  enough,  even  the  extending  direction  and  the 
approximate  number  of  the  spines  of  this  appendage  are  constant 
in  the  species. 


CHENG  :  REVISION  OF  THE  CHINESE  MECOPTERA  9 

The  female  genital  segment  (or  9th  segment)  consists  of  an 
upper  normally  developed  tergite  and  a  lower  subgenital  plate 
which  has  a  free  posterior  margin  forming  an  opening  for  the 
genital  cavity.  In  some  species,  the  subgenital  plate  is  very 
broad  and  its  lateral  margins  overlap  the  sides  of  the  9th  ter- 
gite (tjederi,  fig.  12)  ;  others  are  narrow  and  their  lateral  mar- 
gins are  enclosed  by  the  well  developed  9th  tergite  (semifasciata, 
etc.,  fig.  122).  The  posterior  margin  of  the  subgenital  plate 
differs  from  species  to  species.  In  tetrazonia,  etc.,  it  is  narrowed 
towards  the  apex  (fig.  93),  in  leei,  etc.,  it  is  rounded  (fig.  125), 
in  most  of  the  species,  it  is  slightly  emarginated  (kimminsi,  fig. 
16)  and  in  japonica,  it  has  a  V-shaped  distal  incision.  Inside 
the  genital  cavity  and  just  above  the  subgenital  plate,  there  is 
a  highly  sclerotized  internal  skeleton.  The  latter  shows  a  desired 
specific  variability  and  individual  constancy  and  has  been  used 
for  identification  by  several  authors  for  the  past  ten  years.  This 
plate  is  often  supported  by  an  inner  pair  of  very  dark  pig- 
mented rods  or  an  axis.  In  most  species,  the  axis  is  long  and  ex- 
tends beyond  the  plate  of  the  internal  skeleton  (flavipennis, 
etc.,  fig.  23),  in  others,  it  is  less  developed  and  confined  by  the 
plate  (tjederi,  etc.,  fig.  17),  and  in  some  others  the  axis  is  greatly 
reduced  or  absent  (japonica,  etc.,  fig.  100).  Curiously  enough, 
all  the  females  of  the  diceras  group  have  a  small  axis,  i.  e., 
slender  and  not  extending  beyond  the  plate  of  the  internal 
skeleton.  The  above  mentioned  features  of  both  male  and  female 
genital  structures  are  constant  in  the  individuals  of  each  species, 
and  show  simultaneous  modifications  in  the  different  species. 
They  therefore  serve  as  excellent  characteristics  for  identifica- 
tion. The  following  keys  to  both  male  and  female  Panorpa  are 
based  mainlv  on  these  characteristics  mentioned.

short  anal  horns.  Fore  wing:  length,  11  mm.;  width,  3.5  mm.; 
membrane  hyaline  without  markings  except  for  a  slight  suspicion 
of  gray  at  the  apex ;  neuration  distinct,  Sc  extends  to  the  ptero- 
stigmal  area,  R2  is  forked  and  R1?  R3,  R4,  Rg  are  simple,  usually 
one  crossvein  occurring  between  Rj  and  R2.  Hind  wing:  similar 
to  the  fore  wing.  Male  genitalia :  genital  bulb  rounded ;  coxopo- 
dites  rather  long ;  harpagones  slender,  the  outer  margin  slightly 
concave  at  the  middle,  the  inner  margin  with  a  small  distal  lobe 
and  a  larger  pointed  proximal  lobe ;  hypandrium  inconspicuous, 
hypovalvae  long,  reaching  to  the  base  of  the  harpagones,  nar- 
rowed proximally,  much  broadened  distally,  with  rounded  tips; 
parameres  complex,  each  consisting  of  a  narrow  basal  stalk,  which 
gives  rise  to  three  branches,  pectinately  arranged,  the  basal 
branch  being  the  shortest,  the  others  about  equal ;  preepiproct 
with  prominent  distal  lobes,  the  incision  being  almost  quadrate. 

Female  unknown. 

Type  (  S  )  :  Tachienlu,  Sikang ;  in  McLachlan  Collection. 

Distribution:  Tachienlu,  Sikang;  9  miles  south  of  Tachienlu, 
Sikang  (8500-13,000  ft.),  June  25-27,  1923   (D.  C.  Graham). 

This  species,  which  has  double  anal  horns  in  the  male,  belongs 
to  the  diceras  group.  I  have  not  seen  the  type.  According  to 
Carpenter's  drawing,  this  species  resembles  stotzneri  Esben- 
Petersen  in  general  appearance.  However,  the  rounded  tips  of 
the  hypovalvae  and  the  pointed  proximal  lobes  of  the  harpagones 
make  its  recognition  easy.

According  to  Tjeder,  the  body  characters  of  the  male  of  this 
species  agree  wholly  with  McLachlan 's  original  description  for 
Panorpa  diceras  McLachlan.  In  the  characteristics  in  size,  color 
of  head,  body  and  legs,  and  shape  of  wings,  the  5  agrees  per- 
fectly with  the  8  .   The  color  of  the  wings  is  distinctly  different. 


CHENG  :  REVISION  OP  THE  CHINESE  MECOPTERA  17 

Besides  the  smoky  pterostigma,  there  is  a  subtriangular  smoky 
brown  oblique  spot,  extending  from  the  pterostigma  down  into 
the  cellula  between  Rg  and  M1  +  2  (just  before  the  fork-point). 
The  additional  side  plates  of  the  7th  to  8th  abdominal  segments 
are  wholly  absent,  the  tergites  are  comparatively  narrow  while 
the  sternites  are  very  broad  (with  their  lateral  margins  reaching 
up  to  the  dorsal  surface),  and  the  pleural  regions  are  very  nar- 
row and  situated  latero-dorsally.  The  detail  drawings  of  both 
$  and  9  genitalia  were  given  by  Tjeder.  According  to  these 
drawings,  the  genital  bulb  of  $  genitalia  is  oval;  coxopodites 
rather  long,  U-shaped;  harpagones  very  broad  at  the  base  but 
strongly  tapering  into  a  very  acute  and  hooked,  curved  apex,  the 
outer  margin  slightly  concave  at  the  middle,  the  inner  margin 
with  a  median  small  tooth-like  process  and  a  large  basal  tooth 
directed  inwards;  hypandrium  inconspicuous;  hypovalvae  slen- 
der, slightly  broadened  and  diverging  towards  each  other  in  the 
distal  half,  reaching  to  the  base  of  the  harpagones ;  parameres 
complex,  each  consisting  of  a  narrow  basal  stalk,  which  gives 
rise  to  four  branches ;  one  of  these  arises  inwardly  from  about 
the  middle  of  the  stalk,  the  others  arise  further  distally  and 
continue  nearly  straight ;  preepiproct  broad,  narrowed  towards 
apex,  which  is  broadly  emarginated ;  aedeagus  smoothly  emar- 
ginated  distally,  both  apical  and  lateral  processes  inconspicuous. 
Female  genitalia :  the  subgenital  plate  is  very  broad,  and  its 
lateral  margins  overlap  the  sides  of  the  9th  tergite ;  at  the  hind 
margin  the  plate  appears  broad  and  tongue-like,  extending 
through  this  tongue-like  process  farther  backwards  than  the  9th 
tergite ;  internal  skeleton  very  broad,  posterior  arms  of  the  plate 
blunt  and  stout,  strongly  folded,  leaving  between  them  proxi- 
mally  a  smoothly  rounded  space ;  axis  short,  lying  wholly  within 
the  plate  and  ending  behind  the  basal  flaps  of  the  plate,  which 
are  very  large,  and  lie  close  to  one  another,  with  their  apical  ends 
directed  upwards.

This  species  belongs  to  the  diceras  group.  I  have  not  seen 
the  types.  According  to  Tjeder 's  drawings,  it  is  closest  to  diceras 
McLachlan  in  general  appearance.   However,  the  hypovalvae  axe

not  broadened  towards  the  apex  as  in  those  of  diceras.  The  para- 
meres  of  this  species  are  apparently  four-branched,  whereas 
those  of  diceras  are  only  three-branched.  According  to  Tjeder, 
the  wings  of  the  female  of  this  species  show  great  similarity  to 
those  of  Panorpa  bicornuta  McLachlan  (from  Japan),  as  figured 
by  Esben-Petersen,  but  the  female  genitalia  of  this  species  are 
very  different  from  those  of  bicornuta.

streaks ;  thorax  with  a  black  longitudinal  streak  along  each  mar- 
gin ;  1st  to  5th  abdominal  segments  of  male  lemon-colored,  with 
a  black  streak  along  each  margin,  last  few  abdominal  segments 
with  indication  of  a  darker  color ;  the  hind  border  of  third  ter- 
gite  produced  in  a  short  lobe ;  sixth  segment  somewhat  swollen, 
and  its  hind  margin  above  produced  in  two  club-shaped  anal 
horns;  abdomen  of  female  yellowish,  with  a  black  streak  along 
each  side.  Fore  wing:  length,  17  mm.,  membrane  faintly  yellow- 
ish tinged,  tip  of  the  wings  strongly  bordered  with  yellowish 
brown ;  venation  blackish  brown,  Sc  reaching  to  the  pterostigma. 
which  is  prominent.  Hind  wing:  length,  15  mm.,  similar  to  the 
fore  except  that  Sc  reaches  only  half  way  to  the  pterostigma. 
Male  genitalia:  according  to  Esben-Petersen 's  drawing,  the  geni- 
tal bulb  is  rounded ;  coxopodites  rather  short,  harpagones  slen- 
der, each  with  pointed  and  inwardly  curved  apex,  the  outer 
margin  very  slightly  concave  at  the  middle,  the  inner  margin 
with  a  sharp  median  tooth  and  a  rounded  proximal  lobe ;  hypan- 
drium  inconspicuous;  hypovalvae  greatly  broadened  towards 
truncated  apex,  and  nearly  reaching  to  the  base  of  the  harpa- 
gones ;  parameres  apparently  three-branched  according  to  Esben- 
Petersen  's  drawdng,  but  unfortunately  the  structure  is  not  com- 
pletely shown.  The  female  genitalia  have  been  worked  out  by 
Tjeder.    The  additional  side-plates  of  the  7th  segment  are  large

aud  apically  grown  together  with  the  7th  tergite.  The  additional 
side-plates  of  the  8th  segment  are  wholly  grown  together  with 
the  8th  tergite,  which  thus  appears  much  broader  (in  lateral 
view)  behind  the  spiracle  than  before  it;  the  7th  and  8th  ster- 
nites  are  comparatively  narrow  and  appear  in  lateral  view  as 
narrow  borders  only;  the  9th  tergite  is  longer  than  the  8th  seg- 
ment; subgenital  plate  appears  broadly  oval  with  tip  slightly 
produced,  smoothly  rounded ;  distally  the  plate  bears  several 
strong  black  setae ;  internal  skeleton  rather  large,  the  plate 
broadened  near  the  base,  posterior  arms  well  developed,  long, 
rounded  and  somewhat  converging,  the  axis  very  short  and 
situated  wholly  within  the  plate.

This  species  belongs  to  the  diceras  group.  I  have  not  seen 
the  types.  According  to  Esben-Petersen's  and  Tjeder's  drawings, 
it  is  closest  in  general  appearance  to  Panorpa  diceras  McLachlan. 
However,  the  hypovalvae,  though  broadened  distalby  as  in  diceras, 
are  truncated  distally,  whereas  those  of  diceras  have  a  rounded 
apex.  The  proximal  lobes  of  the  harpagones  of  this  species  are 
rounded,  not  pointed  as  in  diceras.  Unfortunately,  Esben-Peter- 
sen's drawing  of  the  male  type  does  not  show  details  of  the 
structure  of  the  parameres  or  of  the  aedeagus.

valvae  prominent,  only  very  slightly  broadened  distally,  reaching 
to  the  base  of  the  harpagones;  parameres  complex,  consisting  of 
a  slender  basal  stalk,  which  gives  rise  to  three  branches,  a  small 
one  on  the  inner  side,  a  long  middle  branch,  which  extends  well 
up  between  the  harpagones,  and  a  shorter  outer  branch,  which 
curves  inwardly  in  back  of  (i.e.,  above)  the  second  branch; 
preepiproct  broad,  with  long  distal  lobes ;  aedeagus  with  rounded 
apical  processes  and  rounded  lateral  processes.  Female  genitalia  : 
posterior  border  of  subgenital  plate  rounded,  slightly  emargi- 
nated;  internal  skeleton  small,  the  axis  very  small,  not  project- 
ing beyond  the  plate ;  the  plate  attached  to  a  chitinous,  hood- 
shaped  membrane,  which  extends  slightly  beyond  the  axis.

This  species  belongs  to  the  diceras  group.  It  is  the  most  widely 
distributed  of  all  the  double  anal  horn  species.  It  differs  from 
the  other  species  by  the  curved  harpagones  and  the  peculiar 
configuration  of  the  parameres  of  the  male.  It  should  be  noted 
that  the  structure  of  both  the  subgenital  plate  and  the  internal 
skeleton  of  the  female  is  very  similar  to  that  of  stotzneri  Esben-

orpa cornigera  McLachlan,  which  belongs  to  the  cornigera  group, 
as  established  by  Issiki.  However,  many  parts  of  the  male  and 
female  genitalia  and  especially  the  shape  of  the  parameres  and 
that  of  the  apical  processes  of  the  aedeagus  make  it  easily  recog-

This  species,  possessing  a  single  anal  horn,  belongs  to  the

whereas  that  of  emarginata  is  maculated  with  a  slight  suspicion 
of  gray.  The  male  genitalia  differ  from  those  of  centralis  by 
the  less  rounded  genital  bulb  and  the  longer  and  sharper  para- 
meres.

Distribution:  Beh-luh-din  (6000  ft.),  30  miles  north  of  Cheng- 
tu, Szechwan ;  July  12  to  Aug.  27. 

This  species,  possessing  a  single  anal  horn,  belongs  to  the  cen- 
tralis group.  At  present,  there  are  four  known  species  in  this 
group.  The  wing  membrane  of  flavipennis  is  deep  yellow,  where- 
as that  of  the  other  three  species  is  colorless,  lacteous  or  grayish 
brown.  The  male  genitalia  differ  from  those  of  the  other  three 
species  in  the  more  slender  hypovalvae  and  the  possession  of 
distinct  lobes  on  the  harpagones.

Distribution :  same  as  holotype. 

This  species,  which  has  no  anal  horn  in  the  male,  differs  from 
the  others  of  the  davidi  group  by  its  elliptical  genital  bulb,  with 
long  and  slender  parameres.  [  have  not  seen  this  species.  The 
drawing  of  the  genital  bulb  (fig.  57)  is  based  upon  Carpenter's 
drawing  which  he  made  at  the  Museum  National  in  Paris  in 
1938.  The  wing  markings  resemble  Panorpa  cheni  n.  sp.  How- 
ever, the  structure  of  the  genital  bulb  is  quite  different  from 
that  of  the  latter.

Body  mostly  black;  vertex  brown,  with  a  blackish  spot  en- 
closing the  ocelli;  rostrum  blackish  at  the  apex;  thorax  black 
on  the  dorsum  and  sides;  2nd  and  3rd  abdominal  segments  black

segments  brownish  red  ;  median  process  of  the  third  tergite  rather 
long,  extending  posteriorly  and  in  contact  with  the  conical  pro- 
jection on  the  caudal  portion  of  the  fourth  tergite ;  the  hind 
border  of  the  6th  segment  furnished  with  a  group  of  short  hairs 
dorsally  and  ventrally.  Fore  wing  :  length,  17  mm. ;  very  narrow ; 
membrane  with  a  strong  yellowish  tinge,  markings  smoky  brown  ; 
pterostigmal  band  absent ;  basal  band  represented  by  a  narrow 
streak,  extending  from  the  place  where  1A  joins  the  hind  margin

pterostigma  prominent,  red  in  color.  Hind  wing :  length,  16  mm. ; 
similar  to  the  fore,  except  that  the  interrupted  basal  band  is 
entirely  absent.  Male  genitalia :  genital  bulb  oval ;  coxopodites 
not  very  long ;  harpagones  long  and  slender,  the  outer  margin 
concave  near  the  middle,  inner  margin  with  a  basal  process;  hy- 
pandrium  very  slender,  conspicuous ;  hypovalvae  slender,  with 
rather  pointed  tips,  not  reaching  to  the  base  of  the  harpagones; 
preepiproct  slender,  with  a  deep  U-shaped  distal  incision. 

Female  unknown. 

Type  (  $  )  :  Mou-pin,  Sikang  (David)  ;  in  Museum  National 
d'Histoire  Naturelle,  Paris. 

Distribution :  same  as  type. 

This  species,  belonging  to  the  davidi  group,  is  close  to  the 
kongosana  group,  as  established  by  Issiki  (this  group  comprises 
two  known  species,  both  of  which  are  continental,  i.e.,  Korean). 
However,  the  wing  markings  are  quite  different  from  those  of  the 
latter  group.  I  have  not  seen  this  species.  The  drawings  of  the 
genital  bulb  and  of  the  preepiproct  are  based  on  Esben-Peter- 
sen's,  which  he  made  at  the  Museum  National  in  Paris.  Un- 
fortunately, his  drawings  of  the  male  type  show  nothing  of  the 
structure  of  the  parameres  and  that  of  the  aedeagus.

This  species,  belonging  to  the  davidi  group,  differs  from  other 
described  Panorpa  by  its  short  harpagones  and  broad  hypan- 
driura  of  the  $  genitalia.  The  peculiar  structure  of  the  internal

This  species  belongs  to  the  davidi  group  and  resembles  Panorpa 
cladocerca  Navas  in  the  wing  markings.  However,  in  cladocerca, 
the  wing  has  more  extensive  markings  and  the  marginal  spot  is 
always  present,  whereas  in  trifasciata,  the  three  bands  of  the 
wing  are  much  narrower  than  those  of  cladocerca  and  the  mar- 
ginal spot  is  absent.  The  genitalia  of  trifasciata  differ  from  those 
of  cladocerca  by  the  peculiar  basal  lobes  of  the  harpagones  of 
the  male  and  the  triangular-shaped  subgenital  plate  of  the 
female.

the  marginal  spot  of  the  wing  is  prominent,  whereas  that  of 
davidi  is  absent.  The  harpagones  of  the  male  genitalia  of  this 
species  have  broad  basal  lobes,  whereas  those  of  davidi  are  absent. 
The  yellowish  body  color  and  the  peculiar  structure  of  the  fe-

This  species,  belonging  to  the  davidi  group,  resembles  Panorpa 
davidi  Navas  and  P.  flavicorporis  n.  sp.  in  the  wing  markings, 
but  is  quite  different  in  both  the  male  and  the  female  genitalia. 
The  parameres  of  the  male  genitalia  of  both  davidi  and  flavicor- 
poris  are  simple,  whereas  those  of  cheni  are  branched.  The  sub- 
genital  plate  of  the  female  genitalia  of  flavicorporis  is  long  and 
slender,  whereas  that  of  cheni  is  triangular.

Body  brown ;  vertex  dark  brown ;  thoracic  nota  and  abdominal 
tergites  very  dark  brown ;  anal  horn  of  male  absent.  Fore  wing : 
length,  12  mm. ;  width,  3.5  mm. ;  membrane  faintly  yellow,  mark- 
ings blackish  brown;  pterostigmal  band  complete  with  rather 
narrow  basal  branch  and  a  separated  apical  branch,  the  latter 
connected  with  the  apical  band  to  form  a  hyaline  window  which 
encloses  a  faint,  brown  spot ;  basal  band  represented  by  two 
spots,  the  large  one,  situated  on  the  anal  margin  of  wing,  is  very 
large  with  a  hyaline  window;  apical  band  large,  usually  united 
with  the  apical  branch  of  pterostigmal  band,  and  within  its 
area,  there  are  two  hyaline  bands  and  one  large  hyaline  win- 
dow;   basal    spot    appears    as    a    transverse    band    along    the 


CHENG  :  REVISION  OF  THE  CHINESE  MECOPTERA  37 

anal  margin  of  the  wing;  marginal  spot  elongated,  band-like, 
united  with  the  basal  branch  of  pterostigmal  band  to  form  a 
V-shaped  marking;  pterostigma  prominent;  crossveins  not  mar- 
ginated.  Hind  wing :  similar  to  fore  wing  in  markings,  except 
that  the  left  "arm"  of  the  "V"  is  usually  interrupted.  Male 
genitalia :  genital  bulb  rounded,  coxopodites  long,  U-shaped ; 
harpagones  short,  outer  margins  slightly  concave ;  prominent 
lobes  on  inner  margin  of  the  harpagones  near  the  base ;  hypan- 
drium  rather  long,  conspicuous;  hypovalvae  short,  close  to  each 
other  at  the  middle  of  the  genital  bulb,  and  extending  slightly 
beyond  the  base  of  the  harpagones;  parameres  simple,  each  con- 
sisting of  a  slightly  flattened  process,  with  a  few  short  barbs  on 
the  inner  surface  distally,  and  terminating  in  a  longer  series  of 
barbs  directed  inwards;  preepiproct  much  narrower  distally, 
with  a  pair  of  broad  terminal  lobes,  close  together.  Female 
genitalia:  subgenital  plate  with  rounded  posterior  margin;  in- 
ternal skeleton  large,  with  two  long,  slender  distal  processes  and 
a  pair  of  large,  ear-like  flaps  laterally;  the  usual  axis  is  short, 
but  there  is  a  very  slender  median  process  extending  posteriorly.

Distribution  :  same  as  types. 

This  strikingly  marked  species,  belonging  to  the  davidi  group, 
is  easily  recognized  by  the  oblique  stripe  traversing  the  middle 
of  the  wing,  and  extending  posteriorly  and  distally  from  the 
anterior  margin.  The  short  hypovalvae  of  the  male  genital 
bulb  are  unique  among  the  known  Chinese  species  of  Panorpa, 
but  are  very  much  like  those  of  certain  Japanese,  Siberian  and 
Formosan  species  (e.g.,  Panorpa  preyeri  McLachlan,  wormaldi 
McLachlan,  and  peterseana  Issiki),  to  which  obliqua  Carpenter 
is  undoubtedly  closely  related.

apical  band  to  form  another  hyaline  spot ;  basal  band  represented 
by  two  spots ;  the  one  situated  on  the  anal  margin  of  wing  is  very 
large  and  includes  a  hyaline  spot;  apical  band  large,  usually 
united  with  the  apical  branch  of  pterostigmal  band,  and 
within  its  area  there  are  one  large  hyaline  spot  and  two  hyaline 
bands;  basal  spot  appears  as  a  transverse  band  along  the  anal 
margin  of  wing ;  marginal  spot  elongate,  band-like,  united  with 
the  basal  branch  of  pterostigmal  band  to  form  a  V-shaped  mark-

This  species  resembles  Panorpa  obliqua  Carpenter  in  the  wing 
markings,  but  differs  in  the  female  genitalia.  The  subgenital 
plate  of  obliqua  has  a  rounded  posterior  margin,  whereas  that 
of  implicata  is  slightly  concave.  The  axis  of  the  internal  skeleton 
of  obliqua  is  short,  whereas  that  of  implicata  is  long.  The  posi- 
tion of  this  species  in  the  above  grouping  is  not  determined.

This  species,  belonging  to  the  davidi  group,  resembles  Panorpa 
approximata  Esben-Petersen,  which  is  in  the  amurensis  group, 
as  established  by  Issiki  (this  group  comprises  four  known 
species,  all  of  which  are  known  as  continental,  i.e.,  E.  Siberia 
and  Korea),  but  differs  in  several  respects.  Esben-Petersen 's 
drawing  of  the  male  genitalia  of  approximata  shows  that  the 
hypandrium  is  rather  long  and  the  distal  end  of  the  preepiproct 
is  only  slightly  emarginated.  The  distal  part  of  the  hypandrium 
of  this  new  species  is  deeply  cleft  to  form  the  narrow  bases  of  the 
hypovalvae ;  the  distal  end  of  the  preepiproct  has  a  narrow 
U-shaped  distal  incision.  Unfortunately,  according  to  Esben- 
Petersen,  the  type  of  approximata  (  5 )  lacks  the  parameres,  so 
I  cannot  compare  the  genital  structures  of  these  two  species  in 
detail.

This  species,  belonging  to  the  davidi  group,  resembles  the  com- 
mon European  species  Panorpa  communis  Linne  and  P.  fukiensis 
Tjeder  in  the  wing  markings,  but  differs  in  the  structure  of  the

This  species,  belonging  to  the  davidi  group,  is  very  common  in 
Japan.  Issiki  has  established  a  japonica  group  which  included 
this  species,  Panorpa  klugi  MeLachlan,  P.  nipponensis  Navas  and 
P.  obscura  Miyake.  Apparently  japonica  resembles  in  general 
appearance  these  three  Japanese  species.  However,  the  wing 
membranes  of  klugi  and  nipponensis  are  strongly  yellowish  and 
that  of  obscura  is  ochraceous  yellow,  whereas  that  of  japonica  is

only  slightly  yellow.  The  male  genitalia  of  japonica  also  show 
some  differences  from  those  of  the  other  three  allied  species.  It 
is  interesting  to  note  that  the  aedeagns  of  the  male  and  the 
internal  skeleton  of  the  female  of  japonica  are  similar  to  those  of 
most  Neopanorpa.

CHENG :  REVISION  OF  THE  CHINESE  MECOPTERA  49 

This  species,  belonging  to  the  davidi  group,  differs  from  all 
the  formerly  described  Panorpa  by  its  genital  structures.  The 
parameres  of  the  male  are  most  unusual,  as  is  also  the  form  of 
the  internal  skeleton  of  the  genital  segment  of  the  female.

Distribution  :  same  as  types. 

This  species,  belonging  to  the  davidi  group,  differs  from  the 
formerly  described  Pernor  pa  in  its  wing  markings ;  the  basal  band 
is  as  broad  as  in  Panorpa  dado  cere  a  Navas,  but  its  pterostigmal 
band  is  quite  different.  The  structure  of  the  male  genitalia, 
especially  the  six  spines  on  the  distal  coxopodites,  makes  its 
recognition  easy.

segment  narrow  at  the  base,  cylindrical  and  black  in  color 
dorsally,  with  a  sudden  swelling  near  the  middle,  the  upper 
border  of  the  swollen  part  being  slightly  concave,  the  tip  oblique, 
the  lower  border  convex  basally  and  somewhat  concave  towards 
the  middle;  8th  segment,  with  narrow  cylindrical  base,  gradually 
enlarges,  the  upper  border  being  at  first  concave  and  then 
slightly  convex,  while  the  lower  border  is  almost  straight.  Fore 
wing:  length,  15  mm.;  apex  elliptieally  rounded;  membrane  yel- 
low, markings  dark  rust  colored,  indistinct ;  pterostigmal  band 
complete  with  connecting  basal  branch  and  apical  branch ;  basal

Type  (  $  )  :  Hweihsien,  Kansu;  M.  II.;  in  Hamburg  Museum. 

Distribution  :  same  as  type. 

This  species,  having  a  deep  yellow  wing  membrane,  belongs 
to  the  davidi  group.  It  differs  from  the  other  species  with  yellow 
wing-membranes  by  its  indistinct  wing  markings  and  the  well- 
developed  basal  band.  The  shape  of  the  6-8th  abdominal  seg- 
ments also  makes  its  recognition  easy.  I  have  not  seen  this 
species.  The  above  description  is  based  upon  Navas'  original 
description.

yellowish  brown,  markings  deep  brown ;  pterostigmal  band  com- 
plete, with  a  broad  basal  branch  and  a  broad  apical  branch ;  basal 
band  interrupted;  apical  band  large,  with  a  hyaline  spot;  basal 
spot  absent;  marginal  spot  very  small;  pterostigma  not  very 
prominent.  Hind  wing :  length,  15  mm. ;  width,  4.2  mm. ;  similar 
to  fore  wing,  except  that  the  small  marginal  spot  is  lacking. 
Female  genitalia:  subgenital  plate  elongated,  narrowed  pos- 
teriorly, shallowly  emarginated  at  its  apex,  its  lateral  borders 
bent  to  form  a  narrow  ridge;  internal  skeleton  long,  the  plate 
concave  on  its  median  sides  with  a  pair  of  short  tooth-like 
posterior  arms;  the  axis  long,  extending  beyond  the  plate  for 
exactly  half  its  length. 

Male  unknown. 

Holotype  (  5  )  :  Mt.  Taipai,  Shensi,  July  14,  1943  (Chuan

This  species,  having  a  yellowish  brown  wing  membrane,  differs 
from  Panorpa  flavipennis  Carpenter  by  its  very  long  wing  and 
the  markings  of  the  apical  band.  The  peculiar  shape  of  the 
genital  segment  of  the  female  makes  its  recognition  easy.  The 
position  of  this  species  in  the  above  grouping  is  not  determined.

ileude  Museum,  Shanghai. 

The  material  was  collected  by  Dr.  Piel,  in  honor  of  whom  I 
name  the  species. 

This  species  resembles  Panorpa  pusilla  Cheng  in  body  size, 
wing  venation  and  wing  markings.  It  is  evident  that  they  are 
closely  allied ;  but  the  differences  in  the  structure  of  the  geni- 
talia and  in  the  color  of  the  vertex  and  rostrum  are  so  conspicu- 
ous that  there  is  guod  reason  to  distinguish  it  as  a  good  species. 
The  position  of  this  species  in  the  above  grouping  is  not  de- 
termined.

slightly  overlap  the  lower  margins  of  the  9th  tergite  and  its  apex 
is  very  shallowly  emarginated ;  the  internal  skeleton  large  but 
slender,  the  two  inner  pairs  of  the  plate  prominent,  their  proxi- 
mal part  appearing  to  end  straight ;  posterior  arms  of  the  plate

This  species  resembles  Panorpa  cornigera  McLachlan  super- 
ficially, but  differs  in  the  structure  of  the  female  genitalia.  The 
additional  lateral  plates  of  the  7th-8th  abdominal  segments  of 
this  species  are  not  so  slender  as  those  of  cornigera.  The  sub- 
genital  plate  is  pointed  at  its  posterior  part  and  shallowly  emar- 
ginate  at  its  apex,  while  that  of  cornigera  is  rounded  and  not 
emarginate.  The  internal  skeleton  of  this  species  is  quite  distinct 
from  that  of  cornigera:  the  plate  of  the  former  is  slender  with 
a  small  proximal  part  and  short  posterior  arms,  while  that  of 
the  latter  is  broad,  with  a  well-developed  oval  proximal  part  and 
long  pointed  posterior  arms.  The  axis  of  this  species  extending 
beyond  the  plate  is  less  than  half  the  length  of  the  whole  axis, 
while  that  of  cornigera  usually  extends  beyond  the  plate  more 
than  half  its  length.  The  position  of  this  species  in  the  above 
grouping  is  not  determined.

This  species  resembles  Panorpa  tjederi  (  5  )  in  the  pterostigmal 
band  of  the  fore  wing,  but  differs  in  the  presence  of  its  apical 
band.  The  wings  of  tjederi  are  subobtuse,  whereas  those  of  gut- 
tata are  very  narrow  and  slender.  However,  a  thorough  exami- 
nation of  the  genitalia  of  the  female  type  would  be  highly 
desirable.  The  position  of  this  species  in  the  above  grouping 
is  not  determined.

Genotype:  Neopanorpa  angustipennis  "Westwood. 

This  genus,  common  in  southeast  Asia,  includes  forty  known 
species  in  the  whole  world.  Nineteen  species  have  been  already 
recorded  in  China  and  eleven  new  ones  are  described  below, 
making  a  total  of  thirty.  They  are  distributed  throughout  nine 
provinces.  Since  no  Neopanorpa  have  been  found  in  North  China 
(Shensi,  Kansu)  and  Korea,  I  presume  therefore  that  this  genus 
is  restricted  to  North  Asia.  The  limit  seems  to  be  approximately 
along  latitude  40°. 


CHENG  :  REVISION  OF  THE  CHINESE  MECOPTERA  61 

The  most  obvious  difference  between  Neopanorpa  and  Panorpa 
is  the  length  of  1A,  as  indicated  in  the  key  for  the  family 
Panorpidae.  However,  differences  are  also  apparent  in  the  3rd 
abdominal  tergite  and  in  both  male  and  female  genitalia.  In  the 
male  of  Neopanorpa  the  median  process  of  the  3rd  abdominal 
tergite  tends  to  be  longer  and  more  slender  than  that  of  Panorpa. 
In  most  of  the  species  of  Neopanorpa,  this  process  extends  to  the 
middle  of  the  4th  tergite  or  beyond  the  hind  border  of  the  latter 
(the  only  exception  is  claripennis,  the  process  of  which  is  not 
much  prolonged  and  appears  as  a  semicircular  lobe).  In  most 
species  of  Panorpa,  this  process  is  not  distinct,  only  prolonged 
into  a  small  semicircular  lobe  (the  only  exception  is  stigmalis, 
the  process  of  which  extends  to  the  hind  portion  of  the  4th  tergite 
but  not  beyond  the  hind  border  of  the  latter).  In  the  male  of 
Neopanorpa  the  hypovalvae  are  broad,  mostly  overlapping  each 
other  distally,  whereas  those  of  Panorpa  are  slender,  never  over- 
lapping each  other  distally.  The  parameres  of  Neopanorpa  are 
mostly  absent  or  reduced  to  a  short  slender  thread-like  rod,  some- 
times branched,  without  barbs  or  hairs,  and  partly  or  wholly 
fused  with  the  aedeagus,  whereas  those  of  Panorpa  are  well  de- 
veloped, prominent  and  mostly  with  barbs  or  hairs  on  their  inner 
margins,  absolutely  free  from  the  aedeagus.  The  only  exception 
is  japonica  which  has  reduced  rod-shaped  parameres  and  is  close 
to  those  of  Neopanorpa.  The  aedeagus  of  male  Neopanorpa  is 
mostly  very  small,  and  the  paired  apical  processes  are  short, 
almost  united  together,  whereas  those  of  Panorpa  are  very  prom- 
inent, the  two  apical  processes  being  very  long  and  wide  apart 
from  each  other  (except  in  the  diceras  group,  the  aedeagus  of 
which  has  united  and  short  apical  processes).  The  preepiproct 
of  most  male  Neopanorpa  has  a  rounded  distal  margin  (heii  etc., 
fig.  156)  ;  in  some  species  it  is  slightly  emarginated  (translucida 
n.  sp.,  fig.  223),  and  in  others  it  has  distal  processes  which  are 
directed  inward  towards  the  interior  of  the  bulb  (pilosa,  fig.  192, 
taoi,  fig.  159).  In  Panorpa,  the  preepiproct  has  a  deep  U-shaped 
distal  incision,  although  in  waongkehzengi  it  is  slightly  emar- 
ginate  and  in  japonica  rounded.  This  again  shows  that  japonica 
is  close  to  Neopanorpa.  In  the  female  of  Neopanorpa,  the  sub- 
genital  plate  is  deeply  emarginate  distally  (except  that  of 
kwangtsehi  n.  sp.,  which  is  truncated),  whereas  that  of  Panorpa 


62  BULLETIN  :    MUSEUM   OF   COMPARATIVE  ZOOLOGY 

has  either  a  rounded  apex  or  is  slightly  emarginate;  the  only 
exception  is  in  japonica,  in  which  the  subgenital  plate  is  as  deeply 
emarginate  as  that  of  the  Neopanorpa. 

The  larva  of  Neopanorpa  has  very  short  setae,  whereas  that  of 
Panorpa  has  much  longer  setae.  The  larval  head  sutures  of  Neo- 
panorpa are  usually  accompanied  by  a  broadly  sclerotized  band, 
while  those  of  Panorpa  are  simple.  Moreover,  along  the  posterior 
margin  of  the  10th  abdominal  segment  of  the  larval  Neopanorpa 
there  are  numerous  hairs,  absent  in  Panorpa. 

The  characteristics  which  have  been  used  for  the  specific  identi- 
fication of  Neopanorpa  are  the  median  process  of  the  3rd  abdom- 
inal tergite  of  the  male  and  the  wing  markings  and  both  the  male 
and  female  genitalia.  In  some  species  the  median  process  of  the 
3rd  tergite  of  the  male  is  very  short,  far  from  reaching  to  the 
middle  of  the  fourth  tergite  (claripennis,  fig.  132)  ;  in  others  it 
is  very  long,  extending  far  beyond  the  hind  border  of  the  6th 
abdominal  segment  (choui,  fig.  155).  The  color  of  wing  mem- 
brane is  useful.  In  some  species,  the  wings  are  hyaline  {nigritis, 
fig.  287),  in  others,  they  are  deep  yellow  {caveata  n.  sp.,  fig.  290) 
and  in  some  others,  they  are  faintly  yellow  {cavaleriei) .  The 
markings  of  the  wings  are  different  from  species  to  species.  In 
claripennis,  faoi,  pilosa,  nigritis  and  validipennis,  there  are  no 
markings  at  all.  In  apicata  only  a  shadoAv  of  dark  appears  at  the 
wing  apex.  In  choui  and  kwangtsehi  n.  sp..  the  markings  are 
very  indistinct,  while  in  some  others  they  are  sooty  brown  and 
very  extensive  (cantonensis  n.  sp.,  fig.  302). 

As  in  the  genus  Panorpa,  both  the  male  and  the  female  geni- 
talia of  N eopanorpa  remain  perfectly  stable  even  in  the  minute 
details.  The  general  structures  of  both  sexes  are  just  the  same  as 
those  of  Panorpa.  In  the  male  of  Neopanorpa,  the  outer  margins 
of  the  harpagones  are  mostly  concave  at  the  middle  {caveata 
n.  sp.,  etc.,  fig.  133)  ;  in  others  they  are  distinctly  convex  (taoi, 
fig.  157,  pilosa,  fig.  193).  The  hypandrium  is  usually  long  and 
broad  {caveata  n.  sp.,  etc.,  fig.  133),  but  in  nigritis  and  choui,  it 
is  very  inconspicuous.  The  hypovalvae  are  mostly  short  and 
broad,  usually  tending  to  overlap  each  other  distally  {claripen- 
nis, etc.,  fig.  136),  but  in  some  species,  they  are  narrow  and  slen- 
der (nigritis,  fig.  191,  mutabilis  n.  sp.,  fig.  141).  The  parameres 
are  absent  in  most  of  the  species  (heii  etc.,  fig.  162),  in  others, 
they  are  small  and  rod-shaped  {claripennis,  etc.,  fig.  136)  and  in 


CHENG  :  REVISION  OF  THE  CHINESE  MECOPTERA  63 

some  others,  they  are  branched  (pilosa,  etc.,  fig.  193).  In  the 
female  of  Neopanorpa,  the  subgenital  plate  is  distinctly  emar- 
ginate  distally.  This  emargination  is  diversely  shaped  in  differ- 
ent species.  In  parva,  etc.,  it  is  wide  and  deep  (fig.  184).  In 
pulchra,  etc.,  it  is  slightly  concave  (fig.  182).  In  translucida  n. 
sp.,  etc.,  it  is  V-shaped  (fig.  197 ) .  In  banksi,  etc.,  it  is  U-shaped  (fig. 
177),  and  in  kwangtsehi  n.  sp.,  it  is  exceptionally  truncated,  -with- 
out emargination  at  all  (fig.  198).  The  internal  skeleton  of  the 
female  Neopanorpa  is  usually  U-shaped,  with  the  axis  absent, 
but  in  caveata  n.  sp.  nigritis,  choui,  kwangtsehi  n.  sp.,  translucida 
n.  sp.,  pielina,  mutdbilis  n.  sp.  and  maai  n.  sp.,  the  axis  is  promi- 
nent and  projects  beyond  the  plate  of  the  internal  skeleton.  The 
following  keys  to  both  male  and  female  Neopanorpa  are  based 
upon  the  characteristics  mentioned  above.

The  color  of  the  wing  membrane  of  this  species  resembles 
that  of  Neopanorpa  ophthalmica  Navas  and  sauteri  Esben-Peter- 
sen,  but  the  markings  are  quite  different.  In  ophthalmica  and 
sauteri,  the  apical  band  is  completely  separated  from  the  ptero- 
stigmal  band  and  without  rounded  hyaline  spots,  whereas  that 
of  caveat  a  n.  sp.  is  usually  connected  with  the  pterostigmal  band 
by  some  network-like  bands  and  forms  several  rounded  hyaline 
spots.  The  shape  of  the  hypovalvae  of  the  male  and  the  very 
large  axis  of  the  female  also  make  its  recognition  easy.

This  species,  having  deep  yellow  wing  membranes,  resembles 
the  Formosan  species,  Neopanorpa  ophthalmica  Navas,  in  wing 
markings,  but  differs  in  the  shape  of  the  male  genitalia.  The 
length  of  the  hypovalvae  of  ophthalmica  is  the  same  length  as 
its  hypandrium  (Esben-Petersen,  1921),  whereas  that  of  tien- 
mushana  is  much  shorter  than  its  hypandrium.  The  preepiproct 
of  ophthalmica  is  not  narrowed  toward  the  apex,  and  has  only 
a  slightly  concave  hind  margin,  whereas  that  of  tienmushana  is 
narrowed  towards  the  apex,  with  a  small  U-shaped  distal  in- 
cision.

genital  plate  is  wider  and  the  two  bases  of  the  posterior  arms 
are  smaller  and  are  separated  from  each  other  more  than  those 
of  tienmushana.

This  species  resembles  Neopanorpa  tienmushana  n.  sp.  super- 
ficial^, but  differs  in  the  shape  of  the  hypovalvae  and  especially 
in  the  absence  of  the  small  U-shaped  incision  at  the  distal  end 
of  the  preepiproct.  This  species  also  differs  from  Neopanorpa 
ophthalmica  Xavas  by  the  short  hypovalvae  of  the  male  ami  the 
more  extensive  win?'  markings.

Body  mostly  black ;  vertex  black ;  rostrum  uniformly  light 
brown ;  median  process  of  third  abdominal  tergite  of  male  very 
short.  Fore  wing :  length,  13  mm. ;  width,  3  mm. ;  wing  mem- 
brane hyaline,  slightly  smoky,  without  color  markings,  although 
a  few  of  the  specimens  have  a  very  slight  indication  of  gray  dis- 
tally;  pterostigma  large,  dark  gray,  prominent.  Hind  wing: 
similar  to  the  fore.  Male  genitalia :  genital  bulb  elongate ;  coxo- 
podites  rather  long ;  harpagones  slender,  with  a  prominent  lobe 
on  the  inner  margin  proximally ;  hypandrium  conspicuous ; 
hypovalvae  well-developed,  reaching  to  the  base  of  the  harpa- 
gones, flattened  apically  and  much  broader  distally  than  prox- 
imally. Parameres  ver}-  small,  filamentous ;  preepiproct  with 
nearly  truncated  apex ;  aedeagus  with  short  apical  processes, 
united  with  each  other,  lateral  processes  tooth-shaped,  extending 
posteriorly.  Female  genitalia  :  snbgenital  plate  broad,  with  small 
V-shaped  incision  posteriorly ;  internal  skeleton  small,  U-shaped, 
the  axis  apparently  entirely  absent.

This  species,  without  color  markings,  resembles  Ncopanorpa 
apicata  Navas.  However,  according  to  Carpenter's  idea,  the  tip 
of  the  wing  of  apicata  shows  a  prominent  darkening  of  the  apex 
(hence  the  name  apicata),  whereas  that  of  claripennis  lacks  the 
darkened  apex.  Also,  in  Navas'  drawing,  the  wing  of  apicata 
gives  no  indication  of  a  prominent  pterostigma,  whereas  that  of 
claripennis  is  made  very  prominent  by  its  color.  Unfortunately, 
according  to  Navas,  the  type  of  apicata  (  S  )  lacks  the  terminal 
portion  of  the  abdomen,  so  we  shall  never  know  the  genital  struc- 
ture of  the  type.

Distribution :  same  as  type. 

This  species,  without  any  wing  markings,  resembles  Neo- 
panorpa taoi  Cheng  superficially,  but  differs  in  the  structure  of 
the  male  genitalia,  especially  the  parameres.  In  taoi,  the  para- 
meres are  simple,  leaf-like,  whereas  those  of  pilosa  are  branched. 
This  species  also  bears  some  resemblance  to  nigritis  Carpenter, 
but  is  much  larger  and  has  a  lighter  body.  In  nigritis,  the  outer 
margins  of  the  harpagones  of  the  male  are  normal  and  smooth, 
whereas  those  of  pilosa  are  distinctly  convex  at  their  base.

This  species  superficially  resembles  Neopanorpa  cavaleriei 
Xavas  in  the  wing  markings,  but  it  can  be  distinguished  by 
the  smaller  wing  size,  the  greatly  reduced  apical  branch  of  the 
pterostigmal  band  in  the  fore  wing  and  the  entire  lack  of  this

of  this  species  as  compared  with  the  forked  R2a  in  the  rede- 
scribed  figure  of  cavaleriei  by  Esben-Petersen  (1921,  fig.  93). 
This  species  also  resembles  N.  chelata  Carpenter,  in  wing  mark- 
ings, but  these  two  species  are  at  once  distinguished  by  the  forms 
op  both  the  male  and  the  female  genitalia.

88  BULLETIN  :   MUSEUM  OF   COMPARATIVE  ZOOLOGY 

This  species,  having  complete  basal  and  apical  bands  (with  a 
hyaline  spot),  differs  from  the  other  described  Neopanorpa  by 
the  peculiar  structures  of  both  the  male  and  the  female  genitalia, 
i.e.,  no  true  lobes  in  the  harpagones  of  the  male  and  the  long

This  species  differs  from  previously  described  Neopanorpa  by 
its  wing  markings,  especially  the  presence  of  the  additional  band 
which  extends  from  the  outer  part  of  the  pterostigma  to  the 
apical  band  to  form  a  large  hyaline  window.  The  structures  of 
both  the  male  and  the  female  genitalia  are  also  specific  charac- 
ters.

I  have  named  this  species  in  honor  of  Mr.  Maa,  who  has  been 
so  kind  as  to  allow  me  the  loan  of  his  collection. 

This  species  somewhat  resembles  Neopanorpa  mutabilis  n.  sp., 
but  the  gray  color  of  the  wing  markings,  the  shorter  last  few 
abdominal  segments  of  the  male  and  the  short  axis  of  the 
female  internal  skeleton  make  its  recognition  easy.

Body  mostly  black  above ;  vertex  black ;  last  few  abdominal 
segments  brown,  the  others  black  above.  Fore  wing :  length,  15 
mm. ;  width,  3  mm. ;  membrane  hyaline ;  markings  sooty  brown ; 
pterostigmal  band  interrupted,  with  same  broad  basal  branch, 
hut  no  apical  branch;  basal  band  reduced  to  a  few  spots;  apical 
band  entire,  but  narrowed  posteriorly.  Hind  wing :  similar  to  the 
fore.  Female  genitalia :  subgenital  plate  broad,  with  a  small 
U-shaped  distal  incision;  internal  skeleton  large,  the  axis  absent, 
but  with  three  well  developed  plates  at  the  base  of  the  long, 
posterior  arms,  which  reach  to  the  tip  of  the  subgenital  plate. 

Male  unknown. 

Holotype  (  $  )  :  Suifu,  Szechwan  (D.  C.  Graham)  ;  in  U.  S. 
National  Museum. 

Distribution :  same  as  holotype. 

This  species,  having  distinct  wing  markings,  differs  from  other 
described  Neopanorpa  by  the  peculiar  shape  of  the  internal 
skeleton,  which  has  three  plates  at  the  base  of  the  long  posterior 
arms.

complete,  with  a  separated  basal  branch  and  a  narrow  apical 
branch ;  apical  band  complete ;  pterostigma  prominent.  Hind 
wing:  length,  13  mm.;  width,  3.3  mm.;  similar  to  fore  wing, 
except  that  the  basal  band  is  represented  by  a  small  marking 
on  the  hind  margin.  Female  genitalia :  subgenital  plate  broad, 
with  a  U-shaped  distal  incision;  internal  skeleton  large,  U- 
shaped,  posterior  arms  rather  long,  obtuse  distally,  very  large 
basally,  with  a  narrow  sclerotized  bridge  and  a  rounded  mem- 
branous portion  between  them;  axis  apparently  absent. 

Male  unknown. 

Ilolotype  (  9  )  :  Heierhwan  (100  miles  south  of  Tachienlu), 
Sikang,  Sept.  20,  1939  (F.  Y.  Cheng,  Io  Chou  and  Tein  Ho  Hei)  ; 
in  Cheng  Collection,  Taipeh. 

Distribution:  Heierhwan,  Sikang,  Sept,  20,  1939;  Jihti  (20 
miles  east  of  Tachienlu),  Sikang,  Sept.  9,  1939;  AVantung  (50 
miles  south  of  Tachienlu),  Sikang,  Sept.  17,  1939. 

This  species  is  somewhat  variable  with  regard  to  the  markings 
of  the  wings.  In  my  collection,  there  is  one  individual  collected 
in  AVantung,  Sikang,  with  a  greatly  reduced  pterostigmal  band 
on  both  fore  and  hind  wings  and  without  the  basal  band  on 
the  hind  wing. 

The  wings  of  this  species  resemble  those  of  N eopanorpa  dimi- 
diata  Navas  superficially.  However,  in  dimidiata  the  apical 
band  is  well  developed,  with  a  faint  hyaline  spot,  whereas  that 
of  varia  is  interrupted  posteriorly  and  without  a  hyaline  spot. 
Moreover,  the  body  color  of  these  two  species  differs  very  much.

pterostigmal  band  at  the  costal  margin ;  both  basal  and  marginal 
spots  present,  elongated ;  pterostigma  not  prominent.  Hind  wing : 
length,  12  mm.;  width,  2.9  mm.;  similar  to  fore  wing,  except 
that  both  basal  and  marginal  spots  are  entirely  lacking.  Female 
genitalia :  subgenital  plate  broad  at  the  middle  portion,  with 
wide  V-shaped  distal  incision ;  internal  skeleton  small,  U-shaped, 
posterior  arms  rather  sharp  distally,  their  basal  outer  margins 
smoothly  curved,  connected  to  each  other  by  a  bridge,  which  is 
covered  by  a  rounded  large  membranous  part ;  no  axis  present. 

Male  unknown. 

Holotype  (9):  Canton,  Kwangtung;  in  Heude  Museum, 
Shanghai. 

This  species  differs  from  other  described  Ncopanorpa  by  its 
very  broad  wing  markings  and  the  presence  of  the  basal  spot. 
The  peculiar  structures  of  the  female  genitalia  also  make  its 
recognition  easy.

last  few  abdominal  segments  dirty  yellow.  Fore  wing :  length, 
15.5  mm. ;  apex  of  wing  rounded  in  an  elliptical  fashion ;  mem- 
brane appears  smudged  or  very  lightly  touched  with  rust ;  mark- 
ings sooty  brown;  pterostigmal  band  broad,  with  complete  apical 
branch,  which  is  narrow  posteriorly ;  basal  branch  of  pterostig- 
mal band  interrupted,  represented  by  a  spot  at  the  anal  margin 
of  the  wing ;  basal  band  absent ;  apical  band  broad,  complete, 
with  curved  inner  border  and  a  faint  window  posteriorly.  Both 
basal  and  marginal  spots  are  absent;  veins  black  and  strongly 
developed.  Hind  wing :  length,  15  mm. ;  similar  to  the  fore.

CHENG  :  REVISION  OF  THE  CHINESE  MECOPTERA  95 

This  species  resembles  Neopanorpa  varia  Cheng  in  the  struc- 
ture of  the  pterostigmal  band  of  the  wing,  but  differs  in  the 
apical  band.  In  varia,  the  apical  band  is  interrupted  posteriorly, 
without  a  hyaline  spot,  whereas  that  of  dimidiata  is  well  de- 
veloped, with  a  faintly  hyaline  spot  posteriorly.  I  have  not  seen 
this  species.  The  above  account  is  based  upon  Navas'  original 
description.

This  species  has  the  general  wing  pattern  of  Neopanorpa 
cantonensis  n.  sp.,  but  the  wing  is  more  slender  and  the  basal 
spot  is  absent.  It  also  resembles  N.  parva  Carpenter  super- 
ficially, but  has  more  extensive  markings.  The  internal  skeleton 
of  this  species  differs  from  that  of  parva  by  the  widely  divergent 
arms.

I  have  named  this  species  in  honor  of  Dr.  Hsiu  Fu  Chao,  who 
has  been  so  kind  as  to  allow  me  to  borrow  the  material  from 
the  Museum  of  National  Foochow  University. 

This  species,  having  brown  and  extensive  markings,  is  easily 
recognized  by  its  double  hyaline  spots  of  the  apical  band  and 
the  small  V-shaped  internal  skeleton  of  the  female.

that  the  apical  branch  of  the  pterostigmal  band,  the  inner  small 
Y-shaped  band  of  the  apical  band  and  the  basal  band  are 
greatly  reduced.  Female  genitalia :  subgenital  plate  abruptly 
narrow  posteriorly,  with  a  wide  U-shaped  distal  incision;  in- 
ternal skeleton  small,  being  U-shaped,  with  a  rather  long  stalk 
at  its  base,  the  axis  apparently  absent.

This  species,  having  a  large  hyaline  spot  in  the  posterior  part 
of  the  apical  band  of  the  fore  wing,  differs  from  the  other  de- 
scribed Neopanorpa  by  the  shape  of  the  internal  skeleton  of  the

Ilolotype  (  9  )  :  Yim-na-shan,  East  Kwangtung,  June  16,  1936 
(L.  Gressitt)  ;  in  Museum  of  Comparative  Zoology. 

Distribution  :  same  as  holotype. 

I  take  the  liberty  of  naming  this  speeies  in  honor  of  Professor 
F.  M.  Carpenter.  The  species  resembles  Neopanorpa  cavaleriei 
in  appearance,  but  differs  in  the  apical  band  of  the  fore  wing. 
In  cavaleriei,  the  apical  band  is  interrupted  posteriorly  and  is 
connected  along  the  anterior  margin  with  the  pterostigmal  band, 
whereas  that  of  this  species  is  not  interrupted,  has  a  large  hya- 
line spot  and  is  separated  from  the  pterostigmal  band  on  the 
anterior  margin  of  the  wing.  The  R2a  vein  of  cavaleriei  is  forked 
into  lUai  and  K'ja:>,  whereas  that  of  this  species  is  simple.  More- 
over, the  basal  band  of  cavaleriei  is  interrupted,  whereas  that  of 
this  species  is  complete  and  distinct.

Rostrum  long  and  slender;  tarsal  claws  serrated  on  inner 
margins;  wings  are  fully  developed,  slender  and  narrow,  es- 
pecially at  the  base ;  1A  short,  extending  to  the  anal  margin  of 
wing  far  before  origin  of  the  radial  sector ;  abdomen  very  long 
and  slender  in  male,  much  longer  than  the  wings;  6th  to  8th 
abdominal  segments  of  male  much  prolongated ;  genital  bulb  of 
male  with  a  narrow  stalk  basally  (pedunculate). 

Genotype :  Leptopanorpa  ritsemae  McLachlan. 

This  genus,  which  inhabits  mostly  southeast  Asia,  especially 
Japan  and  Java,  is  represented  in  China  by  only  one  species. 
L.  javanica  (Westwood)  ;  the  Chinese  locality  of  this  species 
is  Hainan,  an  island,  which  is  separated  from  the  mainland  by 
a  narrow  sea. 

The  most  obvious  difference  between  Leptopanorpa  and  Neo- 
panorpa is  the  length  of  the  last  four  abdominal  segments  of  the 


100  BULLETIN  :   MUSEUM  OF   COMPARATIVE  ZOOLOGY 

male.  However,  the  genital  structures  of  both  the  male  and  the 
female  of  Leptopanorpa  are  quite  close  to  Neopanorpa.  In  some 
species  of  Lcptopanorpa,  e.g.,  longicauda,  the  last  four  abdom- 
inal segments  of  the  male  are  exceedingly  long,  in  others,  e.g., 
erythrura,  they  are  rather  short.  It  seems  to  me  that  there  is  no 
distinct  difference  between  Leptopanorpa  and  Neopanorpa. 
Whether  or  not  this  characteristic  (prolongation  of  the  last 
four  abdominal  segments  of  the  male)  is  of  generic  significance 
is  not  certain.  A  morphological  study  of  the  larva  of  this  genus 
and  that  of  Neopanorpa  would  be  a  great  help  in  settling  the 
question.  A  knowledge  of  the  life  history  and  feeding  habits  of 
the  Leptopanorpa  is  also  very  desirable.

margin,  sometimes  enclosing  a  whitish  spot  in  its  posterior  part ; 
along  the  front  margin  it  is  narrowly  connected  with  the  ptero- 
stigmal  band ;  basal  spot  absent ;  marginal  spot  present ;  ptero- 
stigma  not  prominent.  Hind  wing :  length,  8-9  mm. ;  similar  to 
the  fore,  except  that  the  basal  band  is  represented  by  only  one 
spot.  The  male  genitalia  have  been  figured  out  by  Lieftinck.  Ac- 
cording to  his  drawings,  the  genital  bulb  is  slender;  coxopodites 
rather  long,  with  truncated  apex ;  harpagones  long,  slender, 
smoothly  incurved  at  apices,  the  outer  margin  slightly  concave 
near  the  base,  the  inner  margin  with  a  basal  rounded  tooth  and 
two  lobes,  opposite  each  other ;  hypandrium  conspicuous,  broad ; 
hypovalvae  broad,  with  rounded  apex,  reaching  beyond  the  base 
of  harpagones,  the  distal  portion  of  hypovalvae  coming  into 
contact  with  each  other;  parameres  simple,  with  slender  and 
twisted  stalk  and  a  greatly  enlarged  apical  portion  (if  I  under- 
stand Lieftinck 's  drawing  correctly)  ;  preepiproct  with  rounded 
tip ;  aedeagus  with  well  developed  and  stout  apical  processes ; 
lateral  processes  curved  backward  and  inward  with  broad  apex. 
The  internal  skeleton  of  the  female  genitalia  has  been  figured  by 
Lieftinck.  According  to  his  drawing,  the  internal  skeleton  is 
very  short  and  comparatively  broad;  the  basal  portion  of  the 
plate  is  in  the  form  of  two  wing-like  structures,  which  are  rather 
twisted  and  turned  dorsad;  mesially  the  two  portions  converge 
and  are  connected  with  each  other  by  a  thin  membrane ;  the 
distal  portion  of  the  plate  well  demarcated ;  posterior  arm  of  the 
plate  short,  with  tooth-like  apex ;  axis  not  present.

This  is  the  second  largest  genus  of  Mecoptei'a,  including  sixty- 
two  known  species  in  the  whole  world.  Seven  species  have 
already  been  recorded  in  China  and  four  new  ones  are  described 
below,  making  a  total  of  eleven.  They  are  widely  distributed  in 
that  country.  Although  only  eleven  species  have  been  found, 
the  localities  cover  the  whole  mainland  of  China,  that  is,  from 
northern  Shensi,  Liaoning  (one  province  of  Manchuria)  to 
southern  Kwangtung,  Yunnan,  and  from  western  Sikang  to 
eastern  Kiangsu.  Some  species,  e.g.,  sinensis  Walker,  besides 
being  common  in  Kiangsu,  Chekiang,  have  also  been  recorded 
in  Korea  and  Japan. 

In  the  classification  of  the  species  of  Bitiacus,  the  chief  charac- 
teristics which  have  been  used  are  the  body  structure  and  wing 
eoloration.  In  some  species,  the  wing  membrane  is  yellow  {sinen- 
sis, etc.),  in  others,  light  brown  {sinicus,  etc.).  The  size  of  the 
wing  affords  some  specific  characters;  in  appendiculatus,  the  fore 
wing  is  shorter  than  17  mm.,  whereas  that  of  sinensis  is  longer 
than  24  mm.  The  apex  of  the  wing  of  most  species  is  obtusely 
angulated,  but  in  carpenteri  n.  sp.,  it  forms  nearly  a  right  angle, 
forming  a  prominent  corner.  The  wing  markings  usually  appear 
as  several  small  spots.  They  are  present  in  all  the  species, 
except  planus  and  appendiculatus.  Most  of  the  venational 
eliaracteristics  are  subject  to  individual  variation.  However, 
there  are  some  venational  features  which  are  of  use  and  value 
in  the  determination  of  species,  especially  for  the  female :  the 
position  of  the  ending  of  1A  and  that  of  cubital  crossvein  (Cuv) 
with  respect  to  the  fork  of  media  (M)  ;  the  presence  or  absence 
of  the  anal  crossvein  (  Av)  ;  and  the  number  of  pterostigmal 
erossveins    (Pcv). 

Another  important  characteristic  is  the  structure  of  the  male 
genitalia,  which  are  not  so  complex  as  those  of  Panorpidae.  The 
tergum  of  the  9th  abdominal  segment  is  deeply  cleft  posteriorly, 
forming  a  pair  of  claspers.  The  shape  of  this  appendage  varies 
in  different  species.  Seen  from  the  side,  it  is  triangular  in  some 
species  (triangularis,  fig.  233)  and  subquadrangular  in  others 
{sinicus,  fig.  245).    Some  species  have  a  caudal  incision  in  each 


104  BULLETIN  :   MUSEUM  OF   COMPARATIVE  ZOOLOGY 

of  the  claspers  (sinensis,  fig.  235),  whereas  others  have  a  single 
long  process  (carpenteri  n.  sp.,  fig.  246).  In  most  species,  the 
posterior  parts  of  the  inner  surface  of  the  claspers  have  a  patch 
of  short,  stout,  sooty-brown  bristles  (sinensis,  etc.,  fig.  255), 
others  have  no  bristles  at  all  (carpenteri  n.  sp.,  fig.  256),  and 
others  have  two  to  three  bristles  which  are  borne  on  lobes  at- 
tached to  the  median,  inner  surface  of  the  claspers.  The  sternum 
of  the  9th  segment  is  a  simple  semicircular  plate.  It  is  not  of 
much  use  for  identification.  The  coxopodites  are  reduced,  mostly 
fused  with  the  9th  sternum.  The  harpagones  are  also  greatly 
reduced.  However,  the  shape  of  this  small  appendage  varies  in 
different  species.  In  some  species,  the  outer  margins  of  the 
harpagones  are  concave  (sinicus,  etc.,  fig.  249)  and  in  others 
convex,  forming  a  prominent  process  (pieli,  fig.  250).  Some  ap- 
pear as  an  inverted  boot,  others  have  a  long  and  slender  distal 
process  (planus,  fig.  248).  Extending  upward  between  the  coxo- 
podites is  a  long  coiled  spiral  filament  or  filum.  A  pair  of 
prominent  lobes,  the  aedeagus  lobes,  project  upwards  on  each 
side  of  the  base  of  the  filament.  In  some  species,  they  are  long 
and  slender  (tienmushana  n.  sp.,  fig.  268)  and  in  others  short 
and  stout  (pieli,  fig.  250).  Some  have  a  rounded  apex  (sinensis, 
fig.  270),  others  have  the  apex  truncated  (pla?ius,  fig.  248).  The 
proctiger  which  extends  dorso-caudad  between  the  preepiproct 
and  the  coxopodites  affords  some  taxonomic  value.  In  some 
species,  it  is  long  and  slender  (carpenteri  n.  sp.,  fig.  262)  and 
in  others  short  and  stout  (gressitti  n.  sp.,  fig.  254).  Some  have 
a  pair  of  lateral  lobes  at  the  middle  (coreana,  fig.  240),  while 
others  have  a  pair  of  long  processes  on  the  dorsal  part  of  the  apex 
(tiennmushana  n.  sp.,  fig.  263).  The  lower  process  of  the  proctiger 
varies  much  in  degree  of  development.  In  some  species,  it  is  very 
long  (carpenteri  n.  sp.,  fig.  262),  in  others,  it  is  very  short  (gres- 
sitti n.  sp.,  fig.  254). 

The  females  of  Bittacus  seem  to  have  lost  the  internal  skeleton 
which  is  so  useful  in  the  taxonomy  of  the  Panorpidae.  The  sub- 
genital  plate  is  not  well-developed,  and  no  taxonomic  value  can 
be  found.  Therefore,  the  identification  of  females  is  based  only 
upon  the  general  body  and  wing  characteristics.

Collection. 

Distribution :  same  as  type ;  Suigen,  Korea,  June  23,  1926 
(Issiki);  Shanghai,  Kiangsu,  China,  June  16-22,  1931-1933; 
Zikawei,  Shanghai,  Kiangsu,  China,  July  17,  1938  (Piel). 

This  species  has  previously  been  known  only  from  Korea. 

Coreanus,  having  a  yellowish  wing  membrane,  differs  from 
other  described  Bittacus  by  the  peculiar  shape  of  its  preepiproct, 
which  is  deeply  cleft  at  the  tip ;  the  upper  branch  of  this  cleft 
is  short,  the  lower  branch  elongate,  broadening  towards  the  apex 
and  curved  inwards.  The  paired  median  lateral  lobes  of  the 
proctiger  also  make  its  recognition  easy.

tal crossvein  (Cuv)  considerably  beyond  the  fork  of  media,  anal 
crossvein  ( Av)  absent ;  pterostigma  not  very  prominent,  con- 
nected with  Rs  by  two  pterostigmal  crossveins  (Pcv).  Hind 
wing :  length,  18-19  mm. ;  width,  5  mm. ;  similar  to  fore  wings. 
Male  genitalia :  preepiproct  triangular  when  viewed  from  side,

with  Rs  by  two  pterostigmal  crossveins  (Pcv).  Hind  wing: 
length,  17.5  mm. ;  width,  4.2  mm. ;  similar  to  fore  wings,  except 
that  there  is  only  one  pterostigmal  crossvein  (Pcv).  Male  geni- 
talia :  preepiproct  with  V-shaped  inner  margins  when  seen  from 
above,  with  truncated  apex ;  the  apical  margins  slightly  con- 
cave, furnished  with  a  series  of  short  black  bristles  on  its  inner 
sides;  posterior  end  of  coxopodites  extending  upward  for  a 
considerable  distance,  with  smooth  apex ;  harpagones  broad 
basally,  very  narrow  and  slender  distally,  with  prominent  inner 
process;  aedeagus  lobes  on  each  side  of  the  base  of  filum  (spiral 
filament)    broaden  towards  apex,  furnished  with  a  bundle  of

This  species,  having  a  yellowish  brown  wing  membrane,  dif- 
fers from  the  previously  described  species  by  the  more  or  less 
truncated  caudal  margins  of  the  preepiproct  in  lateral  view. 
The  slender  harpagones  and  the  broadened  apex  of  the  aedeagus 
lobes  also  make  its  recognition  easy.

Hind  wing :  length,  21  mm. ;  width,  5.4  mm. ;  similar  to  fore 
wings,  except  that  both  cubital  and  pterostigmal  crossveins  are 
represented  by  one  crossvein.  Male  genitalia:  preepiproct  equi- 
laterally  triangular  when  seen  from  side,  the  caudal  margins 
slightly  convex  at  the  middle,  the  posterior  parts  of  the  ventral 
margin  extending  backward  to  form  a  prominent  process;  at 
the  inner  surface  of  the  angle  between  the  above  margins  are 
short  black  bristles;  coxopodites  slightly  curved  upward  with 
emarginate  apex ;  harpagones  short,  with  rounded  tips,  the

CHENG :  REVISION  OF  THE  CHINESE  MECOPTERA  113 

This  species,  having  a  light  brown  wing  membrane,  differs 
from  Bittacus  zoensis  n.  sp.  by  its  less  extended  processes  in  the 
caudal-ventral  portion  of  the  preepiproct. 

Bittacus  carpenteri  n.  sp. 
Figures  246,  256,  262,  269,  307 

Body  light  brown;  vertex  brown,  with  a  deep  brown  marking 
enclosing  ocelli;  rostrum  brown.  Fore  wing:  length,  21.5  mm.; 
width,  5.5  mm. ;  narrow,  with  right  angulated  apex ;  membrane 
light  brown,  with  several  minute  dark  brown  spots,  one  at  the 
fork  where  M  separates  from  Cu1}  one  at  the  base  of  Rs,  one 
at  the  first  fork  of  Rs,  one  at  the  fork  of  R4+5  and  one  at  the 
cubital  crossvein  (Cuv)  ;  veins  brown,  1A  terminating  far 
before  the  level  of  the  fork  of  M ;  the  distal  end  of  R5  and  most 
of  the  crossveins  are  heavily  shaded  with  brown;  cubital  cross- 
vein  located  before  the  fork  of  M,  no  anal  crossvein  (Av)  pres- 
ent; pterostigma  prominent,  connected  with  Rs  by  two  ptero- 
stigmal  crossveins  (Pcv).  Hind  wing:  length,  17.5  mm.;  width, 
4.5  mm. ;  similar  to  fore  wings.  Male  genitalia :  preepiproct 
irregular  when  seen  from  side,  with  a  swollen  caudal  portion 
which  has  a  very  long  caudal  process ;  coxopodites  with  concave 
apex ;  harpagones  very  small,  inwardly  bent ;  aedeagus  lobes  on 
each  side  of  the  base  of  film  (spiral  filament)  narrowed  towards 
apex,  with  truncated  tips;  proctiger  very  long,  slender  at  the 
middle  portion,  with  enlarged  apex  which  is  furnished  with  a 
row  of  hairs;  the  lower  process  very  long,  pointed  towards  its 
apex.

I  take  the  liberty  to  name  the  species  in  honor  of  Professor 
F.  M.  Carpenter,  who  has  allowed  me  to  describe  the  species. 

This  species,  having  a  light  brown  wing  membrane,  is 
easily  distinguished  from  the  other  described  Bittacus  by  the 
apex  of  the  wing  forming  nearly  a  right  angle  and  the  long 
posterior  processes  of  the  preepiproct.  The  very  long  and  slender 
proctiger  and  lower  process  also  make  its  recognition  easy.

BlTTACUS  GRESSITTT  1L  sp. 

Figures  236,  254,  260,  266,  312 

Body  deep  brown ;  vertex  blaek  anteriorly ;  reddish  brown 
posteriorly ;  rostrum  blackish  brown.  Fore  wing :  length,  23.8 
mm. ;  width,  5.3  mm. ;  membrane  light  brown,  with  some  ill- 
defined  reddish  brown  shadows  along  the  margin  of  the  apical 
portion  of  wing;  markings  minute,  blackish  brown,  one  at  the 
fork  where  M  separates  from  Cuj,  one  at  the  base  of  Rs  and 
one  at  the  first  fork  of  Rs ;  veins  brown ;  1 A  terminating  at  the 
level  of  the  fork  of  M,  crossveins  rather  heavilv  shaded  with 
brown,  cubital  crossvein  (Cuv)  located  a  little  beyond  the  fork 
of  M,  no  anal  crossvein  (Av)  present;  pterostigma  rather  prom- 
inent, connected  with  Rs  by  two  pterostigmal  crossveins  (Pcv). 
Hind  wing:  length,  21  mm.;  width,  5  mm.;  similar  to  fore 
wings.  Male  genitalia :  preepiproct  U-shaped  when  seen  from 
dorsal  side,  apparently  emarginate  at  the  tip,  lower  parts  of  this 
emargination  much  produced  and  not  so  curved  inwards  as  in 
Bittacus  chujoi  Issiki  and  Cheng;  upper  parts  short  and  thick; 
both  the  lower  and  upper  parts  are  furnished  with  short  black 
bristles  on  the  interior  sides;  harpagones  longer  than  that  of 
chujoi,  with  broad  bases,  rounded  tips  and  small  inner  processes; 
aedeagus  lobes  on  each  side  of  the  base  of  filum  (spiral  filament) 
slender,  pointed  towards  apex  in  caudal  view;  proctiger  with 
its  posterior  half  bent  upward ;  apex  truncated,  with  only 
very  minute  hairs;  close  to  the  apex  there  is  a  prominent  side 
lobe  covered  with  many  soft  hairs.  Lower  process  short,  but 
apparently  present. 

Holotype  (  $  )  :  Yim-na-shan,  E.  Kwangtung ;  June  12,  1936 ; 
L.  Gressitt;  in  Museum  of  Comparative  Zoology.  Paratypes: 
5  9  9  ,  same  type  locality  and  deposition  as  holotype ;  June  12-17, 
1936;  L.  Gressitt;  in  Museum  of  Comparative  Zoology. 

This  species  is  named  in  honor  of  the  collector,  Dr.  L.  Gressitt. 
It  resembles  Bittacus  corcanus  Issiki  in  the  structure  of  the 
preepiproct,  but  these  two  species  are  at  once  distinguished  by 
the  color  of  the  wing  membrane  and  the  body  size.  This  species 
is  also  closely  allied  to  B.  chujoi  Issiki  and  Cheng  from  Formosa. 
The  preepiprocts  of  these  two  species  have  nearly  the  same 
shape  when  seen  from  the  side.    In  gressitti,  however,  the  lower 


CHENG:  REVISION  OF  THE  CHINESE  MECOPTERA  1  1  ~i 

margins  of  the  preepiproct  are  wholly  (not  just  partly,  i.e.. 
caudally,  as  in  chujoi)  folded  outward  and  the  lower  process 
is  much  longer  and  extends  straighter  than  that  of  chujoi.  Be- 
sides this,  the  bare  apex  of  the  proctiger  of  this  species  is  quite 
easy  to  distinguish  from  that  of  chujoi,  which  has  an  apical 
bundle  of  long  hairs.

Distribution :   same   as  type. 

This  species,  having  a  light  brown  wing  membrane,  differs 
from  the  other  described  Bittacus  by  the  peculiar  shape  of  the 
preepiproct,  which  has  an  irregular  dorsal  margin  and  an  in- 
wardly curved  rounded  apex  when  seen  from  the  side.  The 
slender  and  heavily  marked  wing  also  makes  its  recognition  easy.

No.  2  —  A  Catalogue  of  the  Cerionidae  (Mollusca-Pidmonata) 

By  William  J.  Clench 

INTRODUCTION 

The  Cerionidae,  a  family  of  terrestrial  pulmonate  Gastropoda, 
are  found  on  certain  islands  of  the  West  Indies  and  the  southern 
Keys  of  Florida  from  Miami  south  and  west  to  the  Dry  Tortugas. 
It  is  the  only  family  of  land  mollusks  peculiar  to  the  West 
Indies. l 

They  are  halophiles  and  are  seldom  found  more  than  a  few 
hundred  feet  from  the  sea.  In  the  Bahamas,  however,  they  may 
occur  at  a  much  greater  distance  inland,  particularly  in  lowland 
areas  where  salt  spray  can  reach  them  from  more  than  one 
direction. 

This  family  contains  but  a  single  genus  with  a  few  subgenera 
and  a  vast  number  of  "species"  and  "subspecies."  Probably 
less  than  20  per  cent  of  the  names  now  extant  actually  apply  to 
valid  species  or  subspecies.  The  task  ahead  for  anyone  attempt- 
ing to  monograph  this  group  is  rather  appalling  due  to  the  fact 
that  the  characters  generally  held  stable  in  most  other  groups 
of  mollusks  are,  in  this  group,  wildly  rampant.  Many  recent  as 
well  as  early  describers,  the  present  author  included,  are  and 
were  completely  oblivious  to  the  remarkable  plasticity  of  this 
group  of  mollusks.  I  think  that,  in  this  genus,  nature  is  isolating 
or  mixing  small  elements  of  Colon  populations  as  effectively  as 
man  has  done  with  his  domesticated  plants  and  animals.  Cerion 
lives  mainly  along  the  upper  strand  line,  an  exceedingly  hazard- 
ous area  to  occupy  in  any  region  where  hurricanes  occur.  Here, 
for  short  or  long  periods  of  time,  they  may  build  up  strong, 
vigorous  colonies.  The  appalling  devastation  of  a  hurricane  in 
the  strand  line  is  quite  apparent  to  even  a  casual  observer.  In 
such  an  area,  a  colony  may  be  greatly  reduced  or  even  completely 
exterminated.  The  same  storm  may  move  elements  of  this  colony 
to  a  new  region  and  bring  in  other  elements  of  the  genus  from 
distant  places  by  means  of  flotsam.    This  is  certainly  the  way  it 

1  In  essence,  the  lcnver  Florida  Keys  are  mainly  West  Indian  in  both 
their  fauna  and  flora.  I  do  not  know  of  any  permanent  colonies  of  Cerion 
living  on  the   Florida  mainland. 


122  BULLETIN:    MUSEUM   OK   COMPARATIVE  ZOOLOGY 

appears  to  those  of  us  fortunate  in  having  had  extensive  field 
experience  in  the  West  Indian  region.  Such  a  statement  is,  of 
course,  difficult  to  prove,  but  the  facts  of  distribution  still  remain 
and  their  haphazard  distributional  patterns  seem  to  offer  no  other 
reasonable  explanation.  Like  all  other  land  pulmonates,  the 
larval  stages  are  passed  within  the  egg;  there  is  no  "free  swim- 
ming" stage.  Their  distribution,  beyond  their  ability  to  migrate 
within  a  narrow  ecological  niche,  is  exceedingly  limited  as  far 
as  their  own  mobile  power  is  concerned.  Their  broader  distribu- 
tion is  brought  about  entirely  by  mechanical  means.  A  five-foot 
stream  would  be  an  absolute  barrier  without  such  means  of 
transport. 

The  morphological  characters  of  the  shell  appear  to  be  ex- 
ceedingly variable  and  most  of  the  differences  are  certainly  more 
apparent  than  real.  Few,  if  any,  of  these  characters,  such  as  size, 
degree  of  costation,  coloration,  position  of  the  apertural  teeth, 
convexity  of  the  spire,  or  the  ratio  between  height  and  width, 
are  at  all  stable. 

We  must  take  a  realistic  stand  regarding  the  naming  of  various 
elements  in  this  genus.  We  are  not  dealing  with  a  "normal" 
group  so  far  as  the  usual  specific  characters  are  concerned,  but 
rather  with  a  group  of  mollusks  existing  under  natural  conditions 
that  closely  approximate  the  control  and  isolation  which  have 
brought  about  man's  domesticated  animals  and  plants. 

HISTORICAL  SUMMARY 

As  for  most  of  our  widely  distributed  West  Indian  molluscan 
genera  the  early  work  in  this  group  began  in  the  late  18th 
century.  Surprisingly  enough,  however,  only  a  very  few  of  the 
many  named  forms  that  now  exist  found  their  way  into  the 
European  cabinets  prior  to  1850.  But  even  at  this  time,  few 
names  had  reached  the  printed  page  and  these  few  were  the  re- 
sult mainly  of  the  indefatigable  Cuban  collector  Juan  Gundlach. 
Much  of  coastal  Cuba  was  then  nearly  inaccessible,  at  least  from 
the  land  side,  and  such  named  forms  were  described  from  local- 
ities mainly  within  easj^  walking  distance  of  the  larger  coastal 
cities.  At  this  time,  little  was  known  of  the  richness  of  the 
Bahama  Archipelago.  Early  monographers,  such  as  Kiister  in 
the  Conchylien  Cabinet    (1841-50)    and   Sowerby    (1875-76)    in 


CLENCH:   CERIONIDAE  128 

the  Conehologica  Iconica  tabulated  such  species  as  were  then 
known  without  any  serious  attempt  to  group  them  into  natural 
assemblages.  This  task  was  first  accomplished  by  Pilsbry  in  the 
Manual  of  Conchology,  1901-02.  Prior  to  the  work  of  Pilsbry, 
Maynard  (1889)  started  such  a  study  but  the  several  new  forms 
that  he  described  over  the  course  of  many  years,  from  1889  to 
1924,  completely  submerged  his  original  attempt  at  such  a  com- 
plete classification.  His  work  was  marred  by  many  inaccuracies 
of  all  kinds  and  his  attempts  toward  a  clarification  of  this  com- 
plex problem  dwindled  as  the  jrears  passed,  ending  in  brief  de- 
scriptions and  eventually  in  a  sales  catalogue  with  a  few  "new 
species"  described.  In  fairness  to  Maynard,  however,  the  com- 
mercial side  of  his  venture  was  not  to  gain  profit  for  himself 
but  to  realize  money  to  finance  additional  expeditions  in  quest 
of  these  mollusks  in  which  he  was  so  deeply  interested.  It  seems 
to  me  that  Maynard  failed  to  grasp  much  of  the  importance  of 
his  own  discoveries.  He  failed  to  see  that  he  was  actually  dealing 
with  unit  populations  and  not  with  completely  isolated  entities 
which  he  had  termed  "species."  Somewhere  in  his  writings  he 
mentioned  that  a  wagon  road  on  New  Providence  was  a  complete 
barrier  between  two  of  his  named  ' '  species. ' '  But  he  overlooked 
the  caprice  of  a  single  hurricane  and  the  consequent  mixing  of 
these  two  populations.  Nevertheless,  we  owe  much  to  Maynard 
for  his  early  exploration  of  both  the  Bahama  Islands  and  the 
Cayman  Islands,  as  the  specimens  he  collected  are  still  the 
only  materials  available  for  study  from  many  remote  and  inac- 
cessible localities. 

It  is  most  unfortunate  that  his  writings  were  privately  pub- 
lished and  had  a  very  limited  sale.  He  not  only  wrote  the  text, 
but  cut  his  own  wood  blocks,  and  with  a  small  printing  press 
set  his  own  type  and  printed  his  publications.  His  collection 
was  purchased  from  his  daughter  jointly  by  the  Museum  of 
Comparative  Zoology  and  the  United  States  National  Museum 
in  1931. 

After  1900  many  students  besides  Maynard  and  Pilsbry  added 
materially  to  the  names  in  this  genus ;  Dall,  Bartsch,  Plate,  and 
Clench  for  the  Bahama  Archipelago  and  Aguayo,  Sanchez  Roig, 
Jaume  and  Clench  for  Cuba.  Many  names  were  added  by  H.  B. 
Baker  to  the  uva  complex  of  the  Dutch  West  Indies,  Curacao 
and  its  associated  islands. 


124  BULLETIN  :   MUSEUM   OF   COMPARATIVE  ZOOLOGY 

Mr.  Allison  V.  Armour's  yacht,  the  TJtowana,  made  several 
trips  to  various  islands  in  the  Bahamas  and  by  this  means  much 
Cerion  material  was  collected  for  this  museum  mainly  by 
T.  Barbour  and  J.  C.  Greemvay. 

In  1936,  Mr.  J.  C.  Greenway  and  his  brother  Gilbert  made 
extensive  collections  in  the  Bahamas  by  means  of  a  seaplane. 
Islands  visited  were  Andros,  Grand  Bahama,  the  Abacos,  Great 
and  Little  Inagua.  I  joined  them  for  the  exploration  of  Grand 
Bahama  and  the  Abacos.  During  this  same  trip  I  visited  also 
Eleuthera  Island.  A  year  previously  I  had  explored  rather  ex- 
tensively the  northern  end  of  Cat  Island  and  Little  San  Salvador 
or  Little  Island.  I  was  associated  on  this  trip  with  Henry  D. 
Russell  and  John  Huntington.  Later,  students  and  associates  of 
mine  visited  Long  Island  (Richard  W.  Foster,  Richard  McLean 
and  John  Huntington)  and  Great  and  Little  Inagua  (Richard 
McLean  and  Benjamin  Shreve).  Each  of  these  various  trips 
necessitated  several  days  in  Nassau,  and  much  time  was  devoted 
to  collecting  Cerion  and  other  mollusks  outside  of  this  city  on 
New  Providence  Island. 

In  1007,  Dr.  Plate  published  upon  a  few  species  obtained  on 
islands  in  the  Exuma  group.  During  the  summer  of  1930,  Dr. 
Paul  Bartsch  of  the  United  States  National  Museum  made  an 
extensive  collecting  trip  in  the  southern  Bahamas  visiting  such 
island  groups  as:  Cay  Sal  Bank,  Ragged  Islands,  Crooked  Island 
group,  Little  and  Great  Inagua,  Caicos  and  Turks  Islands.  More 
recently,  Mr.  and  Mrs.  George  F.  Kline  of  Madison,  New  Jersey, 
have  added  to  our  series  of  Cerion  from  a  few  islands  in  the 
Exuma  group  and  from  cays  in  the  Ragged  Islands,  Bahamas. 

Many  others  have  figured  in  the  exploration  of  the  Bahamas, 
mainly  with  other  interests  in  mind  hut,  nevertheless,  much  data 
in  the  form  of  material  have  been  collected  which  will  aid  in  the 
eventual  solution  of  this  mollusk  problem.  More  data  on  the 
historical  side  are  available  in  the  various  studies  which  are 
listed  in  the  bibliography. 

There  are  hut  three  centers  of  "speeiation"  at  the  present 
time,  for  this  genus:  Cuba,  the  Bahamas  and  the  Cayman  Is- 
lands. In  these  islands  the  greatest  number  of  populations  occur. 
Elsewhere,  such  as  Hispaniola,  Puerto  Rico  and  the  Virgin 
Islands  populations  are  exceedingly  few  and  all  appear  to  be 
very  closely  related.    (  hi  both  Hispaniola  and  Puerto  Rico  they 


CLENCH  :  CERIONIDAE  125 

are  to  be  found  only  on  the  south  coasts.  It  is  quite  astonishing 
that  this  genus  has  failed  to  invade  Jamaica. 

At  this  time  only  a  single  group  in  this  complex  has  been 
analyzed  (Clench  and  Aguayo,  1952)  :  the  subgenus  Umbonis. 
This  group  is  limited  to  the  north  coast  of  Cuba  and  the  Baha- 
mas. Distributional  patterns  for  the  species  in  this  group  are 
not  at  all  uniform ;  they  appear  to  be  hit  or  miss  and  based  upon 
chance  introductions. 

it  is  interesting  to  note  that  this  genus  succeeded  in  invading 
the  Dutch  West  Indies.  These  islands  are  far  removed  from  the 
Greater  Antilles  and  the  established  species  complex  on  them 
is  quite  different  from  all  others  in  the  genus.  It  is  possible  that 
this  was  an  early  introduction  and  that  since  then  no  other  mem- 
bers have  invaded  this  area,  so  that  all  of  the  present  named 
entities  are  exceedingly  close  in  their  relationships  and  appear 
to  be  but  unit  populations  of  a  closely-knit  species. 

COLLECTIONS 

Major  collections  of  Cerion  are  to  be  found  in:  the  Academy 
of  Natural  Sciences,  Philadelphia  ;  American  Museum  of  Natural 
History,  New  York  City;  Museum  of  Comparative  Zoology. 
Harvard  University;  Museum  of  Zoology,  University  of  Michi- 
gan; Museo  Poey,  Universidad  de  la  Ilabana,  Habana,  Cuba; 
and  the  United  States  National  Museum,  Washington,  D.C. 
Many  smaller  collections  exist  in  most  museums,  both  in  the 
Americas  and  in  Europe,  but  the  above  institutions  contain 
collections  that  are  rich  both  in  type  material  and  in  geographical 
series. 

GEOGRAPHIC  INDEX 

The  following  list  of  names  is  arranged  geographically  to  aid 
in  locating  the  species  of  Cerion  which  have  been  described  from 
any  given  locality.  Names  of  species  now  considered  synonyms 
have  been  omitted  from  this  list.  This  does  not  mean  that  a' I 
the  names  included  below  refer  to  valid  species  but  only  that  to 
date  no  attempt  has  been  made  to  restudy  most  of  these  forms 
since  they  were  originally  described.  A  good  example  is  that  of 
New  Providence,  Bahamas,  given  below.    Probably  no  more  than 


126 


BULLETIN  :   MUSEUM   OF   COMPARATIVE  ZOOLOGY 


live  or  six  species  exist  on  this  small  island,  yet  the  present  list 
stands  at  82! 

Fossil  species  have  been  included  in  this  list  as  most  of  these 
"fossil"  forms  are  not  old  in  any  geologic  sense. 

In  the  list  of  names  below  we  have  retained  the  original  spell- 
ing. As  Cerion  is  neuter,  all  the  adjectival  specific  names  should 
end  in  urn.

XOTES  ON  THE  GENUS  CERION 

The  following  notes  are  based  upon  studies  in  this  genus  which 
were  made  during  a  rehabilitation  of  certain  portions  of  our 
collection. 


132  BULLETIN  :   MUSEUM   OF   COMPARATIVE  ZOOLOGY 

Subgenus  STROPHIOPS   Dall 

Straphiops  Dall  1894,  Bull.  Mus.  Comp.  Zool.,  25,  p.  121  (type  species,  Pupa 
deoumana  Ferussac  (=C.  regium)  Castle  Island,  Bahamas). 

Pinguita  Maynard  1896,  Contributions  to  Science,  3,  p.  30  (type  species, 
Strophia  dimidiatia  [sic]   Pfeiffer,  monotypic). 

Cyclocerion  Bartsch  1952,  Kevista  de  la  Sociedad  Malacologica  ' '  Carlos 
de  la  Torre,"  9.  p.  1   (type  species,  Cerion  (Cyclocerion)   baconi  Bartsch). 

Both  Pinguita  Maynard  and  C yclocerion  Bartsch  appear  to  be 
absolute  synonyms  of  Strophiops  Dall.  This  group  is  widely 
spread  in  the  Bahamas  and  along  the  northern  coast  of  Cuba. 

Cerion  sanctacruzense  Aguayo  and  Jaume 

Cerion  sanctacruzense  Aguayo  and  Jaume  1951,  Revista  de  la  Sociedad 
Malacologica  "Carlos  de  la  Torre,"  8,  p.  14,  pi.  1,  fig.  14  (Sabanalamar, 
.Santa  Cruz  del  Sur,  Camagiiey,  Cuba ) . 

This  species  was  described  from  Sabanalamar,  which  is  just 
east  of  Santa  Cruz  del  Sur  on  the  southern  coast  of  Camagiiey, 
Cuba.  It  appears  to  be  rather  widespread  in  the  Cayos  de  Doce 
Leguas,  a  long  series  of  small  islands  that  run  Avesterly  and  just 
off  the  coast  from  Santa  Cruz  del  Sur.  Typical  sanctacruzense 
are  smooth,  but  numerous  colonies  from  the  various  islands  are 
both  smooth  and  strongly  ribbed.  We  have  specimens  from  the 
following  localities :  Sabanalamar ;  Santa  Cruz  del  Sur ;  Cayo 
Caguama;  Cayo  Cochiboca ;  Punta  Boca  de  Piedra  and  Cayo 
Anclitas. 

Cerion  politum  Maynard 

Strophia  marmorata  polita  Maynard  1896,  Contributions  to  Science,  3. 
p.  14,  pi.  3,  figs.  3-4   (Cabo  Cruz,  Cuba). 

Cerion  politum  maisianum  Pilsbry  1902,  Manual  of  Conchology,  (2)  14, 
p.  218,  pi.  30,  figs.  89-91   (Punta  Maisi,  Cuba). 

Both  of  the  above  names  apply  to  the  same  species.  Maynard 
was  in  error  in  giving  the  type  locality  as  Cabo  Cruz.  This 
species  occurs  only  at  Punta  de  Maisi,  at  the  extreme  eastern 
end  of  Cuba.  In  color  it  ranges  from  nearly  pure  white  to  mar- 
bled with  brownish.  Both  smooth  and  finely  ribbed  forms  occur 
in  different  colonies  as  well  as  mixed  in  others.

4-5,  Univ.  Habana  (Lengua  do  Pajaro,  Bahia  de  Lebiza,  Mayari,  Oriente, 
Cuba  ). 

All  of  tlie  above  names  apply  to  but  a  single  species.  This  ap- 
pears to  be  a  species  which  is  limited  to  the  margins  of  rather 
large  bays.  Its  distribution  extends  from  Bahia  de  Banes  east  to 
Bahia  de  Yaguaneque  along  the  north  coast  of  Oriente,  Cuba.

Cerion  sanzi  Pilsbry  and  Vanatta  appears  to  be  the  most 
widely  distributed  Cerion  throughout  the  Archipielago  de  Cama- 
giiey, a  long  chain  of  cays  and  little  islands  on  the  northern 
coast  of  Cuba.   This  chain  of  cays  extends  from  Cayo  Guillermo, 


134  BULLETIN:    MUSEUM   OF   COMPARATIVE   ZOOLOGY 

off  Punta  Alegre  to  Cayo  Sabinal,  a  distance  of  125  miles  (200 
kilometers). 

The  synonyms  given  above  all  appear  to  be  this  species  or  else 
hybrid  colonies  in  which  the  sanzi  characters  are  most  prominent. 

Cerion  microdon  Pilsbry  and  Vanatta 

Cerian  mcrassatum  microdon  Pilsbry  and  Vanatta  1896,  Proc.  Acad.  Nat. 
Sei.  Philadelphia,  p.  328,  pi.  11,  fig.  5   (Cuba). 

Cerion  tenuilabre  pygmaeum  Pilsbry  and  Vanatta  189(5,  Proc.  Acad.  Nat. 
Sei.  Philadelphia,  p.  334,  pi.  11,  fig.  9,   (Gibara,  Cuba). 

The  two  names  given  above  appear  to  be  the  same  species.  C. 
mierodon  is  exceedingly  variable  in  size  and  somewhat  in  colora- 
tion. It  occurs  on  both  sides  of  the  harbor  of  Gibara  but  is  very 
rare  on  the  eastern  side.  Most  of  the  specimens  from  the  west 
side  were  collected  dead.  At  the  time  Dr.  Aguayo  and  I  visited 
this  locality  we  found  even  the  dead  specimens  to  be  localized 
in  certain  areas  only  and  not  broadly  distributed  throughout  the 
coastal  region  of  the  harbor.

No.  3  —  Studies  on  New  Zealand  Elasmobranchii.  Part  VI. 
Two  New  Species  of  Etmopterus  from  New  Zealand  1 

By  J.  A.  F.  Garrick 

Zoology  Department,  Victoria  University  College, 
Wellington,  New  Zealand 

Experimental  line-fishing-  off  New  Zealand,  for  the  purpose  of 
adding  to  our  knowledge  of  the  deeper-water  shark  fauna  of  this 
region,  has  resulted  in  the  capture  of  three  specimens  of  Etmop- 
terus representing  two  species  apparently  new  to  science.  These 
specimens  were  caught  off  Kaikoura  on  the  east  coast  of  the 
South  Island,  by  Mr.  Richard  Baxter,  who,  fishing  from  a  16  foot 
dinghy,  collected  one  large  brown  specimen  from  500  fathoms, 
and  a  small  grey-black  specimen  from  200  fathoms  in  November, 
1955.  In  February,  1956,  a  further  grey -black  specimen  was 
caught  in  100  fathoms.  All  captures  were  made  close  inshore,  the 
submarine  topography  of  the  Kaikoura  region  being  such  that 
water  500  fathoms  deep  is  found  within  3  miles  of  the  coast. 

Although  squaloid  sharks  are  fairly  well  represented  in  the 
New  Zealand  fauna,  no  specimens  of  Etmopterus  have  been 
known,  and  geographically  the  nearest  member  of  the  genus  is 
E.  molleri  (Whitley)  1939  of  southern  Australia.  It  is  therefore 
of  considerable  interest  that  the  two  species  of  these  luminescent 
sharks  now  known  to  be  present  should  represent  what  are  more 
or  less  the  extremes  of  morphological  diversity  in  the  genus. 
The  large  brown  specimen,  here  proposed  as  Etmopterus  baxteri 
n.sp.,  in  honour  of  Mr.  Richard  Baxter,  is  akin  to  E.  princeps 
of  the  North  Atlantic  in  its  size  —  which  exceeds  that  of  most 
other  species ;  in  the  uniform  but  random  arrangement  of  the 
dermal  denticles ;  in  the  noticeably  small  and  rounded  pectoral 
fins ;  in  the  rather  plain  colouration  and  inconspicuous  pelvic 
flank  mark ;  and  in  the  high  number  of  cusps  on  the  upper  teeth. 
The  grej^-black  specimens,  named  here  as  Etmopterus  abemethyi 
n.sp.,  for  Mr.  Fred  Abernethy  who  has  contributed  greatly  to 
the  collection  of  New  Zealand  elasmobranchs,  are  closely  allied 
to  the  Pacific  species  E.  lucifer,  E.  brachyurus  and  E.  molleri, 
and  like  them  are  small ;  with  dermal  denticles  arranged  linearly

of  the  Universitv  of  New  Zealand.

on  the  sides  and  upper  surface  of  the  trunk;  with  large  and 
more  angular  pectoral  fins;  with  an  obvious  colour  pattern  and 
conspicuous  flank  marks;  and  with  a  smaller  number  of  cusps 
on  the  upper  teeth. 

Comparison  of  E.  baxteri  and  E.  abernethyi  with  other  species 
of  the  genus,  of  which  twelve  are  listed  by  Bigelow,  Schroeder 
and  Springer  (1953,  p.  238),  though  E.  molleri  (Whitley)  1939 
should  be  added  to  these,  has  been  greatly  facilitated  by  the 
availability  of  specimens  of  E.  spinax,  E.  polli  and  E.  princeps 
provided  by  Drs.  H.  B.  Bigelow  and  W.  C.  Schroeder,  to  whom 
I  am  also  especially  indebted  for  their  generosity  in  supplying 
access  to  their  manuscript  key  to  the  species.

caudal,  10.1 ;  pelvic  and  subcaudal,  14.3. 

Distance  from  origin  to  origin  of :  pectoral  and  pelvic,  35.7 ; 
pelvic  and  subcaudal,  22.2. 

Head  depressed,  wide,  compact,  and  very  large-eyed;  trunk 
moderately  stout,  and  compressed  posterior  to  the  pectorals. 
Height  of  trunk  at  origin  of  pectorals  7.5  in  the  length  from 
snout  tip  to  origin  of  subcaudal.  Length  of  body  measured  to 
the  cloaca,  62  per  cent  of  the  total  length.  Caudal  peduncle  little 
compressed  and  slender,  and  without  lateral  keels  or  precaudal 
pits. 

Dermal  denticles  small,  numerous,  and  in  the  form  of  conical 
thorns,  slightly  curved  and  directed  posteriorly,  and  borne  on 
four-angled  bases.  Each  denticle  carries  six  ridges,  four  of 
which  are  continuous  with  the  ridges  arising  from  the  angles  of 
the  base,  while  two  are  intermediate  ridges  on  the  anterior  face 
of  the  denticle  and  do  not  extend  on  to  the  base.  Denticles  from 
the  head  and  fins  similar  to  those  from  the  trunk.  The  denticles 
are  distributed  uniformly  but  sparsely  so  that  there  are  con- 
siderable interspaces  between  them  where  the  skin  is  visible. 
Their  arrangement  is  random,  at  least  on  the  anterior  two-thirds 
of  the  trunk,  though  towards  the  caudal  peduncle  and  on  the 
tail  they  are  in  more  or  less  regular  longitudinal  rows.  The 
pectoral,  pelvic,  dorsal  and  caudal  fins  are  denticle  covered 
almost  to  their  margins,  except  for  the  ventral  surface  of  the 
pelvic  which  has  a  wide,  naked  zone  distally,  and  the  web  of  the 
second  dorsal  on  which  the  denticles  are  very  sparse.  Other  naked 
regions  of  the  body  include  the  ventral  surface  of  the  tip  of  the 
snout ;  the  upper  and  lower  lips ;  the  axil  of  the  pectoral  where 
the  naked  area  is  large  and  ovoid  in  outline,  extending  along  the 
trunk  well  posterior  to  the  fin  when  the  latter  is  laid  back,  and 
also  continued  on  to  the  upper  surface  of  the  fin  itself  as  a  wide 
band  along  the  posterior  margin ;  the  axil  of  the  pelvic  and  the 
entire  upper  surface  of  the  base  of  this  fin;  the  axil  of  the  first 
dorsal  where  the  naked  area  is  small ;  and  the  axil  of  the  second 
dorsal  where  the  naked  area  is  very  extensive,  reaching  from  in 
front  of  the  origin  of  the  fin  to  behind  its  posterior  free  tip.  In 
all  cases,  the  naked  regions  correspond  with  the  lighter  coloured 
areas  on  the  trunk  and  fins.  Within  the  dark  area  encompassed 
by  the  pelvic  flank  mark,  the  denticles  are  noticeably  smaller

than  the  adjacent  ones,  and  also  the  tips  of  these  denticles  are 
directed  ventrally  rather  than  posteriorly  as  are  the  majority  of 
the  trunk  denticles. 

Head  measured  to  first  gill-opening  6.2  in  the  total  length, 
and  just  less  than  half  the  distance  from  snout  tip  to  first 
dorsal  origin.  Head  noticeably  broad,  its  greatest  width  at  the 
level  of  the  first  gill-opening  where  it  is  1.6  times  the  least  fleshy 
interorbital  width,  the  latter  being  equal  to  the  preoral  distance. 
Width  of  the  head  at  the  level  of  the  nostrils  is  only  slightly 
narrower  than  the  interorbital  width,  so  that  the  contours  of  the 
head  between  these  levels  are  almost  parallel.  The  snout  tip  is 
broadly  rounded,  and  each  nostril  forms  an  abrupt  step  in  the 
contour.  The  snout  is  thick,  slightly  wedge-shaped  in  profile, 
strongly  depressed,  and  flat  above  as  is  the  greater  part  of  the 
head  to  the  level  of  the  spiracles.  Length  of  snout  measured  to 
eye,  3.0  in  the  head.  Eye  very  large,  ovoid,  1.5  times  as  long  as 
high,  its  horizontal  diameter  1.3  in  the  snout.  Spiracle  large,  its 
length  4.0  in  the  horizontal  diameter  of  the  eye,  and  placed  just 
above  the  level  of  the  dorsal  margin  of  the  eye,  and  behind  it  by 
a  distance  equal  to  about  twice  its  own  length.  Gill-openings  of 
moderate  size  and  slightly  oblique;  each  gill-opening  is  deeply 
emarginate,  especially  the  first  in  which  the  tips  of  the  gill- 
filaments  are  visible.  Lengths  of  the  gill-openings  decrease  from 
the  first  to  the  fourth,  but  with  the  fifth  equal  to  the  third. 
Length  of  the  first  gill-opening  1.7  times  that  of  the  fourth,  and 
1.5  in  the  horizontal  diameter  of  the  eye.  Interspaces  between 
the  gill-openings  decrease  posteriorly,  that  between  the  first  and 
second  almost  twice  that  between  the  fourth  and  fifth.  Nostrils 
large,  oblique,  and  well  anterior  on  the  venter  of  the  snout.  Each 
nasal  aperture  subdivided  into  an  anteriorly  directed,  circular, 
anterolateral  aperture  and  an  ovoid  posteromedial  aperture  by 
triangular  nasal  flaps.  The  anterior  nasal  flap  is  large,  pointed, 
and  external  to  the  shorter,  fleshy  posterior  flap.  The  postero- 
medial aperture  is  also  margined  in  front  and  behind  by  a  low 
membrane.  Mouth  broad,  and  only  slightly  arched,  its  width  just 
greater  than  the  preoral  distance,  and  1.9  in  the  length  of  head. 
The  upper  labial  furrows  moderately  long,  and  deeply  incised 
anteriorly,  their  length  1.4  in  the  distance  from  their  anterior 
extremity  to  the  symphysis  of  the  upper  jaw.    The  lower  labial 


176  BULLETIN  :  MUSEUM  OF  COMPARATIVE  ZOOLOGY 

furrows  are  shallowly  incised  and  short,  their  length  about  half 
that  of  the  upper  furrows. 

Teeth  2g_27  ,  dissimilar  in  the  two  jaws.  The  upper  teeth 
erect,  each  with  a  long,  sharply-pointed,  awl-shaped,  smooth- 
edged  major  cusp  flanked  on  each  side  by  up  to  four  small  lesser 
cusps,  and  borne  on  a  longitudinally-striated  bifid  base.  Most  of 
the  upper  teeth  have  three  lesser  cusps  on  each  side  of  the  major 
cusp,  with  the  middle  cusp  of  these  three  considerably  larger 
than  the  others  though  not  more  than  one-third  the  length  of  the 
major  cusp.  A  few  teeth  near  the  centre  of  the  jaw  have  four 
lesser  cusps  on  each  side,  with  the  largest  lesser  cusp  separated 
from  the  major  cusp  by  two  small  lesser  cusps,  while  in  the  teeth 
towards  the  angle  of  the  jaw  there  is  a  reduction  in  the  number 
of  lesser  cusps  to  one  or  two  on  each  side.  Three  series  of  upper 
teeth  functional  at  the  centre  of  the  jaw,  two  towards  the  angles. 
The  lower  teeth  blade-like,  each  with  a  smooth,  little-sculptured, 
rectangular  base  almost  twice  as  high  as  broad,  and  bearing  a 
single,  smooth-edged,  triangular  cusp.  Each  cusp  is  sharply 
notched  laterally,  strongly  oblique,  and  overlaps  the  adjacent 
cusp  so  that  an  almost  continuous  cutting  edge  is  formed.  There 
is  no  median  tooth,  and  the  base  of  the  first  tooth  on  the  left 
side  overlaps  that  of  the  first  tooth  on  the  right.  A  single  series 
of  lower  teeth  functional. 

First  dorsal  small,  short-based,  and  brush-shaped,  its  distance 
from  snout  tip  33.4  per  cent  of  the  total  length.  Height  of  first 
dorsal  1.9  in  its  base,  and  the  latter  4.6  in  the  interspace  be- 
tween the  first  and  second  dorsals.  Length  of  the  posterior  mar- 
gin 1.5  in  the  length  of  the  base;  the  posterior  tip  sharply 
pointed.  The  first  dorsal  spine  short  and  almost  straight,  its 
length  less  than  half  the  distance  from  its  origin  to  the  first 
dorsal  apex.  Interspace  between  the  first  and  second  dorsals 
equal  to  the  distance  from  snout  tip  to  the  axil  of  the  pectoral. 
Second  dorsal  considerably  larger  than  the  first,  and  originating 
above  the  posterior  insertion  of  the  pelvic  base.  Height  of  the 
second  dorsal  2.0  in  its  base,  and  the  latter  3.2  in  the  interspace 
between  the  dorsals.  The  second  dorsal  spine  strongly  curved 
and  long,  its  length  2.5  times  that  of  the  first  dorsal  spine.  Inter- 
space between  second  dorsal  and  caudal  3.0  in  that  between  first 
and  second  dorsals.  Caudal  measured  from  hypural  origin  5.0  in

margin  slightly  sinuous.  The  terminal  lobe  with  a  convex  margin. 
Height  of  the  hypural  1.7  times  that  of  the  epiural,  and  its  lower 
anterior  margin  almost  straight.  The  apex  acutely  angled,  and 
the  posterior  margin  deeply  concave.  The  pectorals  short  and 
wide,  their  length  2.0  in  the  head  measured  to  the  first  gill-open- 
ing, and  their  width  1.4  in  their  length.  The  anterior  margin 
almost  straight,  the  posterior  margin  slightly  convex  and  contin- 
ued without  a  distinct  angle  into  the  distal  margin.  Pelvics 
originating  anterior  to  the  second  dorsal  origin  by  a  distance 
equal  to  the  length  of  the  pectoral.  Length  of  pelvic  base  equal 
to  that  of  second  dorsal  base ;  posterior  margin  short,  its  length 
2.5  in  the  horizontal  diameter  of  the  eye.  The  posterior  tip  of 
pelvic  pointed,  and  terminating  just  anterior  to  the  origin  of  the 
second  dorsal  spine.

external  view  of  dermal  denticles  from  high  on  side  at  level  of  1st  dorsal ; 
B,  lateral  view. 

Colour.  The  overall  colour  of  the  specimen  is  an  almost  uni- 
form, medium  dusky  brown,  slightly  darker  on  the  ventral  sur- 
face and  on  the  fins,  but  considerably  lighter  in  the  regions  which 
are  smooth  and  free  of  denticles,  such  as  the  axils  of  the  fins,  and 
the  lips.  There  is  also  a  vertical  white  band  devoid  of  pigment 
on  the  anterior  surface  of  the  outer  part  of  each  gill-arch,  though 
this  is  visible  only  on  the  first  arch  where  the  anterior  edge  of 
the  first  gill-opening  is  strongly  emarginate.    Despite  the  ap- 


178  BULLETIN  :  MUSEUM  OF  COMPARATIVE  ZOOLOGY 

parent  uniformity  of  colour  of  the  specimen,  close  examination 
reveals  the  presence  of  well-defined,  darker  regions  which  con- 
tribute to  a  pattern  similar  to  that  described  for  other  etmop- 
terids.  These  darker  regions  are  characterised  in  this  speci- 
men chiefly  by  the  presence  of  numerous  small,  black  pits, 
rather  than  by  an  increase  in  the  number  of  typical  chromato- 
phores.  The  black  pits  are  not,  however,  confined  to  the 
darker  regions,  but  are  distributed  more  sparsely  over  the  en- 
tire head,  trunk  and  fins.  The  most  prominent  dark  region  is 
a  longitudinal  flank  mark  above  the  pelvic  fin,  and  of  the  shape 
shown  in  Figure  1A.  As  described  above,  within  the  area  en- 
compassed by  this  flank  mark,  the  dermal  denticles  are  smaller 
and  directed  more  ventrally  than  those  outside  it,  so  that  they 
also  contribute  to  its  definition.  The  pelvic  flank  marks  are  con- 
nected on  the  ventral  surface  of  the  caudal  peduncle  where  they 
form  a  pattern  as  in  Figure  1C.  The  ventral  surface  of  the  ab- 
domen is  also  a  distinct  dark  region,  well  delineated  on  the  flanks 
by  a  denser  concentration  of  black  pits  along  its  edges  than 
elsewhere  on  the  ventral  surface.  Anteriorly  it  is  continued 
under  the  head  and  snout,  but  apart  from  an  ill-defined  trans- 
verse band  under  the  head,  its  extent  is  not  clear.  Other  dark 
marks  present  are  a  narrow,  curved  band  on  the  lower  surface 
of  the  pectoral  fin,  extending  from  the  origin  of  the  fin  to  its 
insertion;  a  short  streak  on  the  anterior  margin  of  each  dorsal 
fin,  close  to  the  tip  of  each  dorsal  spine ;  and  a  prominent,  dark 
line  near  the  tip  of  the  caudal  axis,  parallel  to  and  just  below 
the  terminal  portion  of  the  lateral  line  where  the  latter  is  in  the 
form  of  a  naked  groove.  The  last-mentioned  mark  is  contributed 
to  not  only  by  black  pits,  but  also  by  a  very  thin  black  streak 
along  each  edgo.  of  the  lateral  line  groove.  A  very  few  similar 
black  streaks  are  also  present  sporadically  on  the  sides  of  the 
trunk,  where  they  are  short  and  appear  to  be  derived  from  the 
fusion  of  contiguous  black  pits.  The  lining  of  the  mouth  is  a 
light  dusky  brown,  as  is  the  lining  of  the  body  cavity. 

Luminescence.  The  black  pits  which  contribute  most  of  the 
colour  pattern  to  the  specimen,  and  the  few  black  streaks  which 
are  present,  appear  to  be  identical  with  those  of  E.  spinax  in 
which  thev  are  known  to  be  luminescent.  However,  Mr.  Baxter 
did  not  notice  any  luminescence  on  the  specimen  when  it  was 


GARRICK  :  NEW  ZEALAND  ELASMOBRANCHII  179 

first  taken  from  the  water,  though  this  was  during  daytime  when 
such  luminescence  might  not  be  obvious. 

Maturity.  The  adult  condition  of  the  specimen  is  evidenced 
by  the  extrusion  of  two  embryos  during  its  transport  from  Kai- 
koura  to  Wellington.  The  embryos  are  two  inches  long,  devoid 
of  pigment,  and  only  part  way  through  development.  They  were 
attached  to  large  yolk-sacs,  though  these  were  ruptured  and 
could  not  be  measured.  At  least  two  other  intact  yolk-sacs  can 
be  felt  within  the  animal,  and  possibly  others  may  be  present 
but  ruptured. 

Discussion.  The  thorn-like  denticles  of  E.  baxteri  readily  dis- 
tinguish it  from  those  species  of  Etmopterus  with  truncate  denti- 
cles, i.e.  frontimaculatus,  pusillus  and  granulosus,  as  they  do 
also  from  paessleri  which  is  described  as  having  denticles  with 
a  larger  central  spine  surrounded  by  several  lesser  spines.  Of 
the  remaining  etmopterids,  all  of  which  have  denticles  with  a 
single  spine,  four  more  are  separable  from  baxteri  on  denticle 
characters  —  namely,  virens,  in  which  the  denticles  are  thorn- 
like but  very  short  and  low,  and  spinax,  hillianus  and  schultzi, 
which  have  elongate,  bristle-like  denticles;  though  as  the  dif- 
ferences between  these  species  and  baxteri  in  this  respect  are  less 
distinctive  than  those  between  baxteri  and  the  species  with 
truncate  or  multispinose  denticles  mentioned  above,  it  is  perhaps 
better  not  to  rely  on  them  alone  as  primary  specific  characters. 

Compared  with  virens,  baxteri  is  heavy-bodied  and  short- 
tailed  (the  distance  from  pelvic  origin  to  tip  of  caudal  42.6  per 
cent  of  the  total  length  in  baxteri,  53  per  cent  in  virens).  From 
villosus,  baxteri  differs  in  the  very  much  shorter  predorsal  length 
(equal  to  less  than  the  distance  from  origin  to  origin  of  the  first 
and  second  dorsals  in  baxteri,  but  reaching  from  first  dorsal 
origin  to  almost  the  upper  caudal  origin  in  villosus).  The  two 
noticeably  short-tailed  Pacific  species,  brachyurus  from  the 
Philippines  and  molleri  from  southern  Australia,  differ  from 
baxteri  not  only  in  their  short-tailedness  (the  length  of  the  upper 
caudal  margin  two-thirds  and  three-fourths  of  the  distance  from 
the  rear  ends  of  the  pelvic  bases  to  the  lower  caudal  origin  in 
brachyurus  and  molleri  respectively,  but  more  than  one  and  a 
third  times  in  baxteri)  but  also  in  the  linear  arrangement  of 
the  denticles  on  the  sides  of  their  trunks;  their  proportionately 
longer  pectoral  fins  (reaching  to  the  first  dorsal  when  laid  back 


1  80  BULLETIN  :  MUSEUM  OF  COMPARATIVE  ZOOLOGY 

in  brachyurus  and  molleri,  but  falling  well  short  of  this  level 
in  baxteri)  ;  and  their  more  attenuate  pelvic  flank  marks.  The 
same  differences  apply  between  lucifer  and  baxteri,  though  in 
lucifer  the  length  of  the  upper  caudal  margin  is  proportionately 
longer  than  in  brachyurus  or  molleri  but  still  considerably 
shorter  than  in  baxteri. 

Of  the  etmopterids  with  bristle-like  denticles,  i.e.  schultzi,  hil- 
lianus and  spinax,  schultzi  is  clearly  distinct  from  baxteri  not 
only  in  its  very  elongate  caudal  fin  (the  upper  margin  of  the 
caudal  almost  equal  to  the  distance  from  snout  tip  to  the  tip 
of  the  pectoral  when  the  latter  is  laid  back  in  schultzi,  but 
reaching  only  to  the  second  gill-opening  in  baxteri)  but  also  in 
its  peculiar  frayed  and  fringe-like  fin  margins  which  differ 
from  those  of  all  other  etmopterids.  E.  hillianus  has  a  greater 
peduncular  length  than  baxteri  (the  distance  from  the  rear  ends 
of  the  pelvic  bases  to  the  lower  caudal  origin  as  long  as  the 
distance  from  snout  tip  to  pectoral  origin  in  hillianus,  but  reach- 
ing only  midway  between  spiracle  and  first  gill-opening  in 
baxteri)  ;  while  spinax  is  readily  separable  from  baxteri  by  its 
much  narrower  head  (head  width  equal  to  the  preoral  distance 
in  spinax,  but  more  than  one  and  a  half  times  this  distance  in 
baxteri)  •  its  shorter  and  less  concave  gill-openings ;  and  the  shape 
of  the  dark  markings  on  the  ventral  surface  of  the  trunk  and 
peduncle. 

The  remaining  etmopterids  to  be  compared  with  baxteri,  i.e. 
polli  and  princeps,  both  agree  with  this  species  in  being  more  or 
less  plain  and  dark  coloured,  and  in  having  thorn-like  denticles 
which  are  in  random  but  uniform  arrangement.  E.  polli,  how- 
ever, is  distinctive  in  having  a  short  interdorsal  space  (reaching 
much  less  than  the  distance  from  snout  tip  to  first  gill-opening 
in  polli,  but  extending  to  the  axil  of  the  pectoral  in  baxteri)  and 
a  longer  pectoral  which  reaches  behind  the  base  of  the  first 
dorsal  spine  when  laid  back.  In  baxteri  and  princeps  the  pec- 
torals are  short,  their  tips  failing  to  reach  the  first  dorsal  origin, 
while  further  agreement  between  these  species  is  seen  in  the 
noticeable  broadness  of  the  head,  the  long  and  concave  gill- 
openings  (which  expose  the  lamellae  of  the  first  gill-arches),  and 
the  vertical  white  markings  on  the  outer  part  of  the  gill-arches. 

E.  baxteri  differs  from  princeps  in  having  a  shorter  tail  (the 
length  from  pelvic  origin  to  tip  of  caudal  equal  to  distance  from 


GARRK'K  :  NEW  ZEALAND  ELASMOBRANCITII  181 

snout  tip  to  posterior  tip  of  the  first  dorsal  fin  in  baxteri,  but 
reaching  to  midway  between  first  dorsal  tip  and  pelvic  origin  in 
princeps)  ;  a  shorter  caudal  fin  (the  upper  caudal  margin  reach- 
ing from  snout  to  second  gill-opening  in  baxteri  but  from  snout 
tip  to  pectoral  origin  in  princeps)  ;  a  more  conspicuous  and  dif- 
ferently shaped  pelvic  flank  mark;  less  oblique  nostrils;  and 
upper  teeth  mostly  with  7  or  9  cusps  rather  than  the  5  cusps  in 
princeps.  Moreover  the  arrangement  of  the  lesser  cusps  of  the 
upper  teeth  in  baxteri,  where  a  very  small  lesser  cusp  is  sand- 
wiched between  a  larger  lesser  cusp  and  the  major  cusp,  differs 
from  that  in  not  only  princeps  but  also  all  other  etmopterids 
where  the  lesser  cusps  usually  diminish  uniformly  in  size  from 
the  major  cusp  outwards.

Head  depressed,  long,  and  very  large-eyed ;  trunk  moderately 
slender,  and  compressed  posterior  to  the  pectorals.  Height  of 
trunk  at  origin  of  pectorals  8.7  in  the  length  from  snout  tip  to 
origin  of  subcaudal.  Length  of  body  measured  to  the  cloaca,  53 
per  cent  of  the  total  length.  Caudal  peduncle  little  compressed 
and  slender,  and  without  lateral  keels  or  precaudal  pits. 

Dermal  denticles  small,  slender  and  thorn-like,  borne  on  four- 
angled  bases  and  with  their  tips  directed  slightly  posteriorly. 
Each  denticle  is  six-ridged,  as  in  E.  baxteri,  though  the  ridges 
are  less  steep  and  fail  to  extend  to  the  tip  of  the  denticle.  The 
denticles  are  numerous,  and  well-spaced ;  arranged  in  random  on 
the  ventral  surface  of  the  head  and  trunk,  but  in  distinct  parallel 
longitudinal  rows  on  the  sides  and  upper  surface,  the  fins,  and 
the  venter  of  the  peduncle.  Above  the  lateral  line,  the  rows  are 
oblique,  sloping  posterodorsally  on  the  head  and  in  front  of  the 
first  dorsal  fin,  but  with  their  slope  flattening  out  and  reversing 
behind  the  latter  level.  Below  the  lateral  line,  the  rows  are  hori- 
zontal. The  line  of  demarcation  between  the  linear  arrangement 
of  the  denticles  on  the  sides  and  the  random  arrangement  below, 
is  sharp,  and  parallels  that  of  the  dark  colour  pattern;  it  skirts 
the  lateral  margin  of  the  snout,  follows  round  the  lower  edge  of 
the  eye,  runs  beneath  the  gill-openings,  and  is  especially  prom- 
inent from  the  axil  of  the  pectoral  to  the  origin  of  the  pelvic. 
Within  the  lateral  pelvic  flank  mark,  the  denticles  are  more 
sparsely  distributed,  are  noticeably  smaller,  and  have  their  tips 
directed  ventrally  rather  than  posteriorly.  The  distal  parts  of 
the  webs  of  the  dorsal,  pectoral  and  pelvic  fins  are  naked,  as  are 
the  terminal  and  hypural  lobes  of  the  caudal  fin.  Other  naked 
areas  include  the  upper  and  lower  lips;  the  interspaces  between 
the  gill-openings ;  and  the  axils  of  the  pectoral,  pelvic  and  dorsal 
fins  (though  none  of  the  latter  is  as  extensive  as  in  E.  baxteri).

Head  measured  to  first  gill-opening  5.3  in  the  total  length,  and 
about  two-thirds  of  the  distance  from  snout  tip  to  first  dorsal 
origin.  Head  long,  flat  above,  and  with  little  change  in  width 
from  the  level  of  the  spiracles  to  the  level  of  the  nostrils.  Inter- 
orbital  width  1.4  in  the  preoral  distance.  The  snout  contours 
rapidly  taper  at  the  level  of  the  nostrils  so  that  the  snout  tip  is 
prominently  pointed.  In  lateral  view  the  snout  is  of  almost  equal 
thickness  from  the  hind  level  of  the  eyes  to  the  nostrils,  though 
anterior  to  the  latter  the  profile  angles  steepen  to  form  the 
bluntly  wedge-shaped  snout  tip.  Length  of  snout,  measured  to 
eye,  2.9  in  the  head.  Eye  large,  ovoid,  nearly  twice  as  long  as 
high ;  its  horizontal  diameter  1.4  in  the  snout.  Spiracle  large,  its 
length  just  less  than  one  quarter  of  the  horizontal  diameter  of  the 
eye,  and  placed  just  above  the  eye  and  behind  it  by  a  distance 
equal  to  one  and  a  half  times  its  own  length.  Gill-openings  small, 
each  vertical  but  concave,  their  lengths  subequal  and  about  4.0 
in  the  eye.  Interspaces  between  the  gill-openings  decrease  slightly 
posteriorly.  Nostrils  large,  oblique,  and  well  anterior  on  the 
venter  of  the  snout.  Each  nasal  aperture  subdivided  by  tri- 
angular nasal  flaps  into  a  circular,  anterolateral  aperture  facing 
to  the  anterior,  and  an  ovoid  posteromedial  aperture  which  is 
margined  in  front  and  behind  by  a  low  membrane.  The  anterior 
nasal  flap  is  attenuate,  sharply  pointed,  and  external  to  the  short 
fleshy  posterior  flap.  Mouth  broad  and  little  arched,  its  width 
1.5  in  the  preoral  distance,  the  latter  1.7  in  the  head.  The  upper 
labial  furrows  deeply  incised  anteriorly,  their  length  equal  to  the 
distance  from  their  anterior  extremities  to  the  symphysis  of  the 
upper  jaw,  and  arranged  so  that  one-third  is  anterior  to  the 
angle  of  the  jaw  and  two-thirds  is  posterior.  The  lower  labial 
furrows  are  shallowly  incised  and  short,  their  length  less  than 
half  that  of  the  upper  furrows. 

Teeth  1g_^7  in  the  male  of  338  mm.,  -fipnr  ^n  ^ne  fema-le  °f 
278  mm.,  dissimilar  in  tbe  two  jaws.  The  upper  teeth  erect,  multi- 
cusped,  each  with  a  long,  sharply-pointed,  awl-shaped,  smooth- 
edged  major  cusp  flanked  on  each  side  by  one  or  two  lesser  cusps, 
and  borne  on  a  longitudinally-striated  base.  Most  of  the  upper 
teeth  have  two  lesser  cusps  on  each  side  of  the  major  cusp,  with 
the  outer  cusp  of  these  two  very  much  smaller  than  the  inner 
which  is  one-third  to  one-half  of  the  length  of  the  major  cusp. 


GABRICK  :  NEW  ZEALAND  ELASMOBRANCHIT  185 

The  teeth  towards  the  angle  of  the  jaw  have  only  one  or  no  lesser 
cusps  on  each  side.  Three  series  of  upper  teeth  functional  at  the 
centre  of  the  jaw,  two  towards  the  angles.  The  lower  teeth  blade- 
like, each  with  a  smooth-faced,  subrectangular,  laterally-rounded 
base,  bearing  a  single,  smooth-edged  triangular  cusp.  Each  cusp 
is  sharply  notched  laterally,  very  strongly  oblique,  and  overlaps 
the  adjacent  cusp  so  that  an  almost  continuous  cutting  edge  is 
formed.  There  is  no  median  tooth,  and  the  base  of  the  first  tooth 
on  the  left  side  overlaps  that  of  the  first  tooth  on  the  right.  A 
single  series  of  lower  teeth  functional. 

First  dorsal  small,  brush-shaped,  originating  just  anterior  to 
the  tip  of  the  pectoral  when  the  latter  is  laid  back.  Distance  from 
snout  tip  to  first  dorsal  origin  29.6  per  cent  to  32.0  per  cent  of  the 
total  length.  Height  of  first  dorsal  1.7  in  its  base,  and  the  latter 
3.8  in  the  interspace  between  the  first  and  second  dorsals.  Length 
of  the  posterior  margin  1.3  in  the  length  of  the  base,  and  the 
posterior  tip  pointed.  The  first  dorsal  spine  short  and  almost 
straight,  its  length  less  than  half  the  distance  from  its  origin  to  the 
apex  of  the  fin.  Interspace  between  the  dorsals  equal  to  or  less  than 
the  distance  from  snout  tip  to  pectoral  origin.  Second  dorsal  much 
larger  than  the  first,  originating  just  posterior  to  the  rear  inser- 
tion of  the  pelvic  base.  Height  of  the  second  dorsal  1.5  in  its 
base,  and  the  latter  2.7  in  the  interspace  between  the  dorsals.  The 
second  dorsal  spine  curved  and  long,  reaching  two-thirds  of  the 
distance  from  its  origin  to  the  apex.  Interspace  between  second 
dorsal  and  caudal  1.8  in  that  between  first  and  second  dorsals. 
Caudal  measured  from  hypural  origin  4.0  in  the  total  length. 
Height  of  the  epiural  6.5  in  its  length,  and  its  margin  straight 
along  most  of  its  length  but  convex  distally.  The  terminal  lobe 
with  a  convex  margin.  Hypural  originates  well  anterior  to  the 
epiural,  its  height  1.6  times  that  of  the  latter.  Anterior  margin 
of  hypural  straight,  the  apex  right-angled  but  rounded,  and  the 
posterior  margin  concave.  Pectorals  noticeably  wide,  their  width 
1.2  in  their  length,  and  the  latter  2.3  in  the  head.  Anterior  and 
posterior  margins  convex,  distal  margin  straight,  and  the  pos- 
terior angle  smoothly  rounded.  Pelvics  originating  well  anterior 
to  the  second  dorsal,  the  interspace  between  first  dorsal  tip  and 
pelvic  origin  equal  to  the  length  of  the  pelvic  base.  Anterior 
and  distal  margin  straight,  and  the  apex  prominent  but  rounded. 


186  BULLETIN"  :  MUSEUM  OP  COMPARATIVE  ZOOLOGY 

The  posterior  tip  sharply  pointed  and  terminating  at  the  level 
of  the  second  dorsal  spine.  Claspers  on  holotype  cylindrical  in 
section,  tapering  to  a  point  posteriorly,  and  showing  no  sign  of 
the  external  features  which  might  be  expected  in  a  mature  ani- 
mal. 

Colour.  Dusky  dark  brown  above,  black  below,  though  a  heavy 
coating  of  mucus  gives  the  specimens  a  greyish  cast.  Dorsal, 
pectoral  and  pelvic  fins  pale  and  translucent,  as  is  the  lower 
posterior  margin  of  the  caudal.  A  large,  ovoidal  pale  area  covers 
the  greater  part  of  the  top  of  the  head,  and  posteriorly  is  con- 
tinued as  a  wide  band  along  the  mid-dorsum  of  the  trunk  and 
peduncle,  though  it  is  interrupted  at  the  dorsal  fins,  the  bases  of 
which  are  dusky  brown.  There  is  also  a  pale  supraorbital  streak 
on  each  side  of  the  head ;  a  narrow  indistinct  pale  band  along 
the  lateral  line ;  and  an  elongate  pale  mark  above  and  anterior  to 
the  pelvic  origin.  In  the  female  of  278  mm.,  the  pale  markings 
are  more  extensive  than  in  the  holotype ;  the  mid-dorsal  band 
extending  well  down  the  sides  of  the  peduncle,  and  the  epiural 
lobe  as  well  as  the  hypural  lobe  is  pale,  though  the  terminal  lobe 
and  the  apex  of  the  hypural  are  darker  than  elsewhere  on  the 
caudal  axis  as  is  also  the  case  in  the  holotype. 

Microscopic  examination  shows  that  the  darkness  of  the  ventral 
surface  is  due  not  only  to  a  greater  number  of  chromatophores 
compared  with  the  condition  on  the  sides  and  upper  surface,  but 
also  to  the  presence  of  numerous  small  black  pits,  as  in  E.  baxteri. 
The  dark  regions  thus  characterised  include  the  undersurface  of 
the  snout,  head  and  trunk  (the  demarcation  line  between  the 
dark  region  below  and  the  lighter  region  above  well  delineated  by 
a  greater  concentration  of  black  pits  than  elsewhere  on  the  under- 
surface—  see  Figure  4C)  ;  the  venter  of  the  peduncle  where  a 
pattern  is  present  as  in  Figure  3C,  though  this  pattern  is  not 
developed  as  clearly  in  the  female  of  278  mm. ;  an  attenuate  pelvic 
flank  mark  of  the  shape  shown  in  Figure  3A ;  a  long,  narrow 
caudal  streak  parallel  to  and  below  the  naked,  grooved  portion 
of  the  lateral  line ;  a  large  curved  streak  on  the  underside  of 
the  pectoral,  and  a  short  arc  on  its  upper  surface ;  and  a  short 
streak  on  the  upper  surface  of  the  pelvic  base.  There  is  also  a 
prominent  row  of  black  pits  and  streaks  along  the  mid-dorsal 
line,  while  others  are  scattered  over  most  of  the  head  and  the

trunk  where  their  concentration  and  arrangement  is  similar  to 
that  known  in  E.  lucifcr.  Lining  of  mouth  dusky  grey;  lining 
of  body  cavity  black. 

Luminescence.  It  is  not  known  if  E.  abernethyi  is  luminescent, 
for  although  the  black  pits  and  streaks  present  resemble  closely 
those  of  luminescent  species  of  Etmopterus,  no  luminescence  was 
observed  in  the  specimens  when  they  were  caught.

Figure  4.  Etmopterus  abernethyi  n.sp.,  holotype,  338  mm.  total  length. 
A,  external  view  of  denticles  from  high  on  side  at  level  of  1st  dorsal;  B, 
lateral  view;  C,  external  view  of  skin  from  lower  part  of  side  of  trunk, 
showing  three  rows  of  denticles  arranged  linearly,  and  others  below 
arranged  at  random.  Note  greater  concentration  of  chromatophores  in  lower 
half,  and  black  pits  which  are  most  numerous  at  demarcation  line  between 
light  and  dark  regions. 

Maturity.  The  claspers  on  the  holotype  lack  the  external  spurs 
which  might  be  expected  in  a  mature  specimen;  the  female  of 
278  mm.  has  not  been  examined  for  its  state  of  maturity  though 
its  small  size  in  comparison  with  the  immature  male  suggests  that 
it,  too,  is  immature. 

Discussion.  As  in  E.  baxteri,  the  thorn-like  denticles  of  E. 
abernethyi  provide  a  ready  character  for  the  separation  of  this 
species  from  front imaculat us,  pusillus  and  granulosus  which  have 
truncate  denticles,  and  from  paessleri  in  which  the  denticles  are 


188  BULLETIN  :   MUSEUM  OF   COMPARATIVE  ZOOLOGY 

multispinose.  The  slender  thorns  of  abernethyi  are  also  obviously 
distinct  from  the  short,  low  denticles  of  virens,  though  in  other 
respects  including  the  general  proportions  of  the  body,  abernethyi 
is  strikingly  similar  to  this  species.  It  differs  from  virens  in  the 
relatively  shorter  peduncular  length  (the  distance  from  the  rear 
ends  of  the  pelvic  bases  to  the  lower  caudal  origin  equal  to  the 
distance  from  snout  tip  to  first  gill-opening  in  abernethyi.  but 
reaching  to  the  pectoral  origin  in  virens)  ;  in  the  lack  of  the 
transverse  pale  markings  on  the  abdomen ;  in  the  presence  of  the 
conspicuous  mid-dorsal  pale  band ;  and  in  the  shape  of  the  dark 
pelvic  flank  mark  and  the  ventral  peduncular  dark  marks.  E. 
abernethyi  differs  from  villosus  in  the  much  shorter  predorsal 
length  (just  greater  than  the  distance  from  origin  to  origin  of 
the  first  and  second  dorsals  in  abernethyi,  but  reaching  from  first 
dorsal  origin  to  almost  the  upper  caudal  origin  in  villosus). 

The  etmopterids  with  bristle-like  denticles  differ  less  from 
abernethyi  in  their  denticle  shape  than  they  do  from  baxteri 
which  has  shorter  and  less  slender  denticles  than  abernethyi.  But 
schultzi  with  its  very  elongate  caudal  (the  upper  margin  of  which 
is  about  equal  to  the  distance  from  snout  tip  to  tip  of  pectoral 
when  the  latter  is  laid  back)  and  its  fringed  fins  cannot  be  con- 
fused with  abernethyi  whose  upper  caudal  margin  is  just  greater 
than  the  length  of  head  measured  to  the  pectoral  and  whose 
fins  are  not  frayed  more  than  is  usual  in  other  etmopterids.  E. 
hillianus  differs  from  abernethyi  not  only  in  its  bristle-like 
denticles,  as  does  spinax,  but  also  in  its  greater  peduncular  length 
(distance  from  rear  ends  of  bases  of  pelvics  to  origin  of  lower 
caudal  equal  to  distance  from  snout  tip  to  pectoral  origin  in 
hillianus,  but  only  to  first  gill-opening  in  abernethyi)  ;  the  shape 
of  the  pelvic  flank  mark  and  the  ventral  peduncular  mark;  and 
the  prepelvic  transverse  pale  band  which  is  lacking  in  abernethyi. 
E.  spinax  has  a  peduncular  length  similar  to  abernethyi,  but 
differs  in  its  random  arrangement  of  bristle-like  denticles,  and  its 
colour  patterns  including  the  shape  and  extent  of  the  pelvic  and 
peduncular  dark  marks. 

E.  polli,  princeps  and  baxteri  have  denticles  only  slightly 
stouter  than  those  of  abernethyi,  but  like  spinax,  these  are  ar- 
ranged in  random  (at  least  anterior  to  the  caudal  peduncle)  and 
thus  markedly  different  to  the  linear  arrangement  in  abernethyi. 


GARRICK  :   NEW   ZEALAND   ELASMOBRANCHII  189 

The  pelvic  flank  marks  of  polli  and  baxteri  are  much  less  elongate 
than  those  of  abernethyi,  while  the  short  interdorsal  space  of 
polli  (equal  to  less  than  the  distance  from  snout  tip  to  first  gill- 
opening  in  polli,  but  extending  to  the  pectoral  origin  in  aber- 
nethyi) and  the  short  stubby  pectoral  fins  of  princeps  and  baxteri 
(failing  to  reach  the  first  dorsal  origin  when  laid  back)  clearly 
distinguish  these  species  from  abernethyi. 

The  remaining  three  etmopterids,  brachyurus,  molleri  and 
lucifer,  all  agree  fairly  closely  with  abernethyi  in  their  overall 
proportions,  their  colour  patterns  (excluding  the  extensive  mid- 
dorsal  pale  band  which  seems  to  be  characteristic  of  abernethyi) , 
and  the  nature  and  arrangement  of  their  denticles.  Bat  brachyu- 
rus and  molleri  are  short-tailed  species,  the  lengths  of  their  upper 
caudal  margins  reaching  only  two-thirds  and  three-fourths  of  the 
distance  from  the  rear  ends  of  the  pelvic  bases  to  the  lower  caudal 
origins,  while  in  abernethyi  the  upper  caudal  margin  is  one  and 
a  quarter  times  this  distance.  Moreover,  in  lateral  view  both 
brachyurus  and  molleri  are  noticeably  more  sharp-snouted 
species,  the  upper  and  lower  profiles  of  the  head  tapering 
smoothly  to  the  snout  tip.  E.  abernethyi  is  less  sharp-snouted, 
the  head  profiles  little  tapered  from  the  eyes  to  the  nostrils  but 
steepening  rapidly  from  the  nostrils  anteriorly,  where  a  distinct 
change  in  the  angles  is  evident.  E.  lucifer  is  intermediate  be- 
tween abernethyi,  and  brachyurus  and  molleri  in  the  length  of 
its  upper  caudal  margin  (which  is  equal  to  the  distance  from 
the  rear  ends  of  pelvic  bases  to  the  origin  of  lower  caudal),  but 
differs  from  abernethyi  in  having  a  greater  peduncular  length 
(distance  from  rear  ends  of  pelvic  bases  to  origin  of  lower 
caudal  equal  to  distance  from  snout  tip  to  pectoral  origin  in 
lucifer,  but  reaching  only  to  first  gill-opening  in  abernethyi)  ; 
a  shorter  snout  (equal  to  or  less  than  the  length  of  the  eye  in 
lucifer,  but  1.5  times  the  eye-length  in  abernethyi)  ;  a  different 
dark  pattern  on  the  undersurf ace  of  the  peduncle ;  and  the  lack 
of  the  extensive  mid-dorsal  pale  band  which  is  so  prominent  in 
abernethyi.

INTRODUCTION 

By 

Raymond  A.  Paynter,  Jr. 

In  northeastern  Chiapas,  bordered  on  one  side  by  the  Rio 
Usumacinta  and  on  the  other  by  the  Rio  Jatate,  with  northern 
limits  near  Palenque  and  southern  limits  along  the  Guatemalan 
border,  there  is  a  vast  area  of  about  15,000  square  kilometers 
of  almost  unexplored  and  very  sparsely  inhabited  virgin  forest 
(Map).  The  region  is  known  as  the  Selva  Lacandona,  because 
of  the  presence  of  scattered  family  groups  of  Lacandon  Indians, 
primitive  and  isolated  remnants  of  the  once  vast  Maya  empire. 

The  Indians,  who  number  less  than  200  individuals,-  have  been 
the  subject  of  considerable  publicity  over  the  past  decade,  par- 
ticularly after  the  discovery  at  Bonampak  of  well-preserved 
murals  in  some  ruined  temples  which  are  occasionally  utilized  by 
the  Lacandons.    Several  expeditions  of  archaeologists  and  an-

thropologists  have  been  into  the  Selva  Lacandona  (see,  e.g.,  Bloni 
and  Duby,  1955),  principally  in  the  vicinity  of  Bonampak,  but 
no  biologists  have  reconnoitered  the  region,  with  the  exception 
of  the  Goodnights  (1953),  who  studied  the  Phalangitis,  and 
Miranda  (1953),  who  made  a  botanical  survey.  Both  investiga- 
tions were  made  at  Monte  Libano,  on  the  edge  of  the  forest,  and 
probably  are  only  indications  of  what  occurs  in  the  interior. 

The  Selva  Lacandona  is  on  the  northeastern  slope  of  the  central 
highlands  of  Chiapas.  There  is  a  gradual  decline  in  altitude 
from  a  maximum  of  approximately  1400  meters,  near  the  Rio 
Jatate,  to  about  100  meters,  at  the  Rio  Usumacinta.  Between 
the  two  principal  rivers  are  many  lesser  streams  whose  courses 
are  very  poorly  known,  but  which  generally  parallel  one  another 
in  a  northwest-southeast  direction.  Scattered  throughout  are  a 
number  of  sizable  lakes  (lagunas),  the  largest  of  which  are 
Laguna  Suspiro  and  Laguna  Ocotal  Grande  (Plate,  upper  fig- 
ure), nine  and  seven  kilometers  in  length,  respectively.  The 
natives  call  the  latter  lake  simply  "Laguna  Ocotal,"  and  all  the 
zoological  material  obtained  there  was  so  labeled,  but  on  a  map 
prepared  by  Frans  Blom  (see  Map)  the  longer  name  is  used,  in 
contradistinction  to  Laguna  Ocotal  Chico,  a  much  smaller  lake 
to  the  northeast. 

It  is  unfortunate  that  nothing  certain  is  known  of  the  drainage 
of  these  important  lakes.  While  they  may  drain  southeast  into 
the  Rio  Lacanja,  thence  into  the  Rio  Lacantun,  and  finally 
into  the  Usumacinta  basin,  there  is  no  evidence  that  this  is  the 
case,  despite  the  predilections  of  cartographers  for  drawing  con- 
necting streams  between  known  lakes  and  known  rivers.  From 
personal  observations,  limited  to  the  region  about  Laguna  Ocotal, 
I  am  inclined  to  believe  that  these  lakes  have  formed  within 
closed-end  solution  valleys.  The  heavily  karsted  limestone 
strongly  suggests  such  an  origin.  Underground  drainage  to  the 
Usumacinta  basin  is  possible,  of  course. 

Miranda  (1952)  has  prepared  a  generalized  vegetation  map  of 
Chiapas  in  which  the  Selva  Lacandona  is  depicted  as  being  cov- 
ered by  high  evergreen  forest,  with  areas  of  pines  and  oaks  at 
the  lakes  and  along  the  southwestern  boundary  of  the  region. 
It  should  be  realized,  however,  that  "high  evergreen  forest"  is  a 
broad  term  embracing  a  great  diversity  of  vegetational  assem-

blages.  For  example,  at  Monte  Libano  the  forest  is  high,  lux- 
uriant, and  has  a  relatively  clear  understory.  It  is  what  is  usually 
referred  to  as  "rain  forest,"  which  in  this  part  of  the  world 
commonly  contains,  among  other  characteristic  species,  mahogany 
(Swietenia  humilis)  and  ramon  (Trophis  racemosa  or  Brosimum 
alicastrum).  On  the  other  hand,  at  Laguna  Ocotal  there  is  a 
forest  which  seems  physiognomically  quite  similar  but  which  is 
markedly  different  in  composition,  lacking,  in  part,  ramon  and 
mahogany,  while  gigantic  oaks  (Quercus  spp.)  are  present.  A  de- 
tailed description  of  the  vegetation  about  Laguna  Ocotal  is  found 
in  Dressier 's  account  (pp.  200-203). 

Nothing  is  known  of  the  climatology  of  the  region.  Since  the 
altitude  and  vegetation  vary  in  the  Selva  Lacandona,  it  is  reason- 
able to  suppose  that  the  climate  is  also  variable.  The  nearest 
location  from  which  weather  records  are  aATailable  is  Tenosique, 
Tabasco,  a  town  at  a  somewhat  lower  elevation  (60  m.)  than  the 
lowest  point  in  the  Selva  Lacandona.  Here  the  mean  annual 
rainfall  is  1697  mm.,  with  June  being  the  wettest  month  and 
March  the  driest ;  the  warmest  month  is  May,  which  has  a  mean 
temperature  of  30.4°C.  and  the  coolest  month  is  January,  with  a 
mean  of  22.9°C.  (Ward  and  Brooks,  1936). 

In  1954,  with  generous  support  from  the  American  Academy 
of  Arts  and  Sciences  and  from  the  Chapman  Memorial  Fund  of 
the  American  Museum  of  Natural  History,  a  party  was  formed 
in  order  to  make  the  first  biological  survey  of  the  interior  of  the 
Selva  Lacandona.  The  group  consisted  of  the  author,  as  leader 
and  ornithologist,  Robert  T.  Paine,  3rd,  as  assistant  ornithologist, 
Elisha  F.  Lee,  as  mammalogist,  Robert  L.  Dressier,  as  botanist, 
and  Mrs.  Ruth  Oberg,  also  a  botanist,  specializing  in  the  Orchi- 
daceae. 

In  early  July  the  party  flew  from  the  capital  of  Chiapas, 
Tuxtla  Gutierrez,  to  Ocosingo  (alt.  850  m.),  a  village  about  one 
hundred  kilometers  to  the  northeast.  Heavy  rains  had  raised 
the  level  of  the  nearby  rivers  and  delayed  for  several  days  the 
arrival  of  our  pack  animals.  Finally,  on  the  morning  of  July  10 
we  started  for  Finca  El  Real  (alt.  600  m.),  which  is  approxi- 
mately 40  kilometers  to  the  east,  and  reached  there  in  the  after- 
noon of  the  following  day. 

At  El  Real  additional  supplies,  mules,  and  men  were  secured 
and  on  July  15,  with  18  mules  and  9  arrieros,  trail-cutters,  etc., 


BIOLOGICAL  INVESTIGATIONS   IN    CHIAPAS,    MEXICO  197 

we  moved  20  kilometers  east  to  the  settlement  of  Monte  Libano 
(alt.  600  m.).  During  the  night  a  number  of  the  mules  strayed 
and  we  were  unable  to  recover  them  and  move  on  until  July  18. 
The  trail-cutters  had  been  sent  ahead  to  clear  the  way  and  pre- 
pare bridges,  but  progress  was  slow  and  difficult  owing  to  the 
mud  and  obstructions  in  the  trail.  About  seven  hours  after  leav- 
ing Monte  Libano  we  arrived  at  El  Censo  (alt.  700  m.),  an 
uninhabited  camping  spot  in  magnificent  rain  forest.  The  fol- 
lowing morning  the  trail  was  poor  during  the  first  hour  of 
travel,  but  then  became  worse  due  to  an  escarpment  which  rises 
over  300  meters  above  the  country  to  the  east.  Ascent  was  made 
by  steep  switchbacks  which  were  barely  surmounted  by  the  pack 
animals.  Beyond  this  point  the  trail  improved  somewhat.  In  the 
middle  of  the  afternoon  our  destination  was  reached  and  a  camp 
was  prepared  at  the  northwestern  end  of  Laguna  Ocotal  (Plate, 
lower  figure),  at  an  altitude  of  950  meters.  Because  of  insufficient 
forage  at  the  lake,  most  of  the  mules  were  returned  to  El  Real,  but 
four  men  remained  to  assist  with  the  collecting  and  maintenance 
of  the  camp. 

The  forest  is  dense  and  the  terrain  rough  around  Laguna  Oco- 
tal, which  means  that  it  is  seldom  practicable  to  work  far  from  a 
trail.  The  only  trails  existing  in  the  area  are  the  one  by  which 
we  entered,  and  a  badly  obstructed  path  leading  to  Bonampak. 
Consequently,  Ave  were  not  able  to  range  as  far  as  desired  and 
even  after  a  month  of  intensive  collecting  did  not  reach  the 
opposite  end  of  the  lake  or  the  pine-covered  ridges  along  its 
southwestern  side.  Future  workers  in  the  region  would  do  well 
to  employ  an  additional  man  or  two  to  cut  new  trails,  thereby 
enabling  the  collectors  to  sample  a  larger  area. 

The  campsite  was  situated  on  a  narrow  strip  of  ground  which 
has  cut  off  a  small  arm  of  the  lake,  impounding  the  water  and 
forming  a  swamp.  Most  of  the  mammals,  and  many  of  the 
amphibians  were  collected  here. 

Although  each  member  of  the  party  concentrated  on  his  field 
of  interest,  unrelated  material  was  collected  whenever  pos- 
sible. For  this  reason  the  bird,  mammal,  and  botanical1  col- 
lections are  probably  the  most  nearly  representative  samples 
from  the  region,  while  the  fish,  reptile,  amphibian,  and  inverte-

brate  collections  contain,  in  the  main,  only  the  more  conspicuous 
elements  of  their  faunas. 

At  the  end  of  a  month  the  mules  were  brought  back  from  the 
ranch  and  on  August  20  the  camp  was  abandoned.  We  returned 
to  El  Real  by  the  same  route  used  in  entering  the  forest  and 
on  August  30  were  flown  from  the  ranch  to  Tuxtla  Gutierrez. 

An  especial  debt  of  gratitude  is  owed  to  the  members  of  the 
field  party.  Their  whole-hearted  cooperation  is  evident  from 
the  large  amount  of  material  which  was  collected,  although  the 
period  was  brief  and  conditions  difficult.  During  preparations, 
and  while  in  the  field,  we  received  much  assistance  and  many 
courtesies  from  Horacio  Albores  of  Ocosingo,  Jose  Tarano  and 
Juan  Bulnes  of  Finca  El  Real,  and  Frans  Blom  of  San  Cristobal 
de  las  Casas.  I  wish,  also,  to  express  my  appreciation  to  Joseph 
C.  Bequaert,  Charles  H.  Blake,  William  L.  Brown,  Jr.,  Frances 
L.  Burnett,  Robert  L.  Dressier,  Charles  P.  Lyman,  Robert  Rush 
Miller,  and  Benjamin  Shreve,  who  have  submitted  the  following 
reports  based  on  material  obtained  during  the  expedition.

THE  VEGETATION  ABOUT  LAGUNA  OCOTAL 

By 
Robert  L.  Dressler  1 

Only  a  preliminary  characterization  of  the  plant  cover  can  be 
made  at  this  time.  Many  important  species  were  not  in  flower  or 
fruit,  and  the  upper  stories  of  the  rich  tropical  evergreen  forest 
were  sampled  only  through  occasional  windfalls. 

Four  main  vegetation  types  may  he  recognized  in  the  area  : 
(1)  Pine  Forest,  or  ocotal,  which  is  usually  at  a  higher  level  on 
a  given  slope  than  is  ni<>ut<  or  selva,  but  occurs  down  to  the 
lake  shore  near  the  campsite.  Pine  forest  is  said  to  extend  south- 
ward for  some  distance  on  the  ridge  west  of  the  lakes.  (2)  Monte, 
a  dense  transition  of  small,  usually  slender,  hardwoods.  This 
vegetation  generally  occurs  between  the  ocotal  and  the  selva  or 
the  lake  shore.  (3)  Tropical  Evergreen  Forest  (selva).  This, 
the  "montana"  of  the  natives,  makes  up  the  hulk  of  the  Selva 
Lacandona  of  eastern  Chiapas  and  apparently  surrounds  the 
lake  area.  (4)  Cloud  Scrub,  a  distinctive  type  limited  to  prom- 
ontories overlooking  the  lake. 

(1)  Pine  Forest.  The  pine  stands  include  some  splendid,  large 
specimens  of  Pinus  tenuifolia  Bentham  (probably  the  only 
species  present  i,  but  are  not  continuous  or  very  extensive  in  the 
area  studied.  The  pines  probably  occupy  only  slopes  and  hilltops 
which  are  loo  well  drained  for  the  more  mesic  forest  types.  Open 
park-like  sites,  which  are  few  and  quite  small,  have  a  grassy 
ground  cover  including  Cyperus,  Scleria,  Dichromena,  and  Pani- 
cum.  In  favored  sites  an  understory  is  formed  by  small  hard- 
wood trees,  such  as  Hauya  h<  ij</<  <ma  Donnell-Smith,  a  reddish- 
barked  tree  with  much  the  aspect  of  madrono,  Saurauia  subal- 
pina  Donnell-Smith,  and  Myrica  cerifera  L.  These  trees  are 
often  quite  mossy  and  hear  a  rich  epiphyte  flora  of  many  species 
of  orchids  and  ferns,  most  of  which  also  occur  in  the  upper 
stories  of  the  selva.  The  pines  themselves  hear  many  epiphytes, 
hut  these  are  of  relatively  few  species,  the  genera  Tillandsia,

BIOLOGICAL    INVESTIGATIONS    I  N    CHIAPAS,    MEXICO  201 

Catopsis,  and  Epidendrum  being  conspicuous.  Chimaphila  macu- 
hifd  (L.)  Pursh  was  found  on  one  slope,  and  a  small  fan-palm 
(Brahea)  occurs  in  dry  sites.  The  greater  pari  of  the  pine  forest 
has  a  great  deal  of  undergrowth  and  might  he  considered  as  a 
marginal  type  passing  into  the  monte. 

(2)  Transition  Forest  or  Monte.  This  is  a  somewhat  diverse 
assemblage  of  vegetations  which  is  characterized  by  its  relatively 
low  height  (mostly  about  5-10  m.)  and  great  density,  its  position 
between  the  pine  forest  and  the  selva,  and  a  very  poor  epiphyte 
flora.  Only  a  few  of  the  trees  making  up  this  vegetation  have 
been  identified.  A  pink-fruited  Hoffmannia  is  frequent,  Acaly- 
pha  gummifera  Lundell  and  Cnidosculus  midtilobus  (Pax) 
Johnston  are  local,  and  Cecropia  was  observed  in  one  stand. 
A  slender  Verbesina  and  Calliandra  houstoniana  (Miller 
Standley  are  frequent  in  drier  sites.  Undergrowth  is  relatively 
scant  in  most  parts  of  the  monte,  but  the  shrubby  Cephaelis 
tomentosa  (Aublet)  Vahl  is  abundant  on  the  selva  side  of  the 
transition,  and  the  fern,  Nephrolepis  cordifolia  (L.)  Presl,  is 
locally  very  abundant   on  the  ocotal  side. 

This  vegetation  may.  on  an  abrupt  slope,  form  a  very  narrow 
zone,  or  it  may  be  more  widespread.  In  one  or  two  sites  near 
the  camp  it  is  fairly  extensive  in  small  areas  that  have  been 
disturbed  (cut  over  for  fire  wood  ami  poles  for  camp  con 
struct  ion.  burnt  over,  and  doubtless  heavily  grazed  by  mules  at 
infrequent  intervals).  At  the  north  end  of  the  lake  clear  evi- 
dence of  disturbance  is  found  in  a  nearly  pure  stand  of  small 
"pomarosa",  Eugenia  (Syzygium)  jambos  L.  (which  may  be 
considered  a  local  phase  of  the  nioiih  ).  This  Asiatic  species  i> 
certainly  introduced.  There  are  two  or  three  very  large  examples 
of  pomarosa  and  two  large  clumps  of  bamboo  near  the  Bonampak 
trail,  which  may  date  to  its  original  introduction.  On  a  slope 
nearby,  in  the  ocotal,  there  is  a  small  area  where  Lantana  camara 
L.,  Trema  micrantha  (L.)  Blume,  Euphorbia  hirta  L.,  and 
Psidium  (probably  /'.  </u<tj<tr<i  L.)  occur  together.  None  of  these 
weedy  species  was  seen  elsewhere  in  the  region,  and  they  surely 
indicate  past  disturbance.  Many  of  the  elements  of  the  monte 
are  probably  those  that  would  occur  in  secondary  growth  any- 
where in  the  area   (for  example.  Cnidosculus,  Cecropia).

(3)  Tropical  Evergreen  Forest  or  Selva.  This  is  the  Selva 
Alta  Siempre  Verde  of  Miranda  (1952).  I  have  used  "selva" 
rather  than  the  local  "montana"  in  my  notes  and  discussion  to 
avoid  confusion  with  "monte".  This  fine  forest  is  similar  to 
(and  continuous  with)  that  near  Monte  Libano,  which  has  been 
described  by  Miranda  (1953b),  though  the  forest  about  Laguna 
Ocotal  lacks  ehicozapote,  ramon,  mahogany,  and  the  fiendishly 
spiny  palm,  Hexopetion.  Ground  cover  in  the  selva  is  relatively 
sparse  and  walking  about  is  easy.  Fallen  fruits  and  flowers  in- 
dicate that  Talauma  mexicana  (de  Candolle)  Don  and  Cymbo- 
jx  lain  in  penduliflorum  (Dunal)  Baillon  are  frequent,  and  the 
fruits  of  Sloanea  were  seen  at  one  place.  Oaks  (Quercus  SJcinneri 
Bentham  and  perhaps  other  species)  occur  frequently,  especially 
in  the  drier  phases  of  the  selva.  These  slightly  more  open,  less 
humid  stands,  curiously  enough,  are  not  to  be  found  near  the 
drier  ocotal,  but  at  some  distance  from  the  lake,  along  the 
Bonampak  trail.  The  selva  adjoining  the  ocotal  (or  transition) 
usually  shows  its  wetter  phases.  The  upper  stories  of  the  selva  are 
rich  in  epiphytes  of  many  kinds.  The  lower  tree  trunks  bear 
ferns,  peperomias,  gesneriads  and  a  few  species  of  orchids 
(such  as  Chondrorhyncha  lendyana  Reichenbach  til.,  Pleurothal- 
lis  eardiothallis  Reichenbach  til.,  Maxillaria  maleolens  Sehlechter, 
and  M.  nasuta  Reichenbach  fil.)  which  are  largely  or  quite  re- 
stricted to  this  habitat.  Collinia,  Eleutheropetalum,  and  several 
species  of  Chamaedorea  were  the  only  palms  seen  in  the  selva; 
tree  ferns  (Cyathea)  are  locally  abundant. 

(4)  Cloud  Scrub.  This  vegetation,  probably  comparable  to 
the  "elfin  woodland"  of  the  West  Indies,  was  found  only  on 
cliff  tops  overlooking  the  west  side  of  the  lake  (the  prevailing 
winds  are  from  the  east,  across  the  water).  These  local  and  rela- 
tively inaccessible  sites  were  not  visited  by  the  expedition  zool- 
ogists. The  limestone  promontories  are  very  well  drained  and, 
probably  for  this  reason,  support  only  relatively  small  trees 
(predominantly  Clusia  rosea  Jacquin?),  but,  while  the  arboreus 
elements  are  comparable  in  size  and  form  to  monte  ha  jo  or 
chaparral,  the  great  atmospheric  moisture  supports  an  abundance 
of  epiphytes.  These  epiphytes  are  largely  mosses  and  ferns,  but 
some  orchids,  Ericaceae  and  other  epiphytes  of  the  high  selva 
also  flourish  in  the  Clusia  scrub. 


BIOLOGICAL  INVESTIGATIONS   IN    CHIAPAS,    MEXICO  208 

These  collections  and  notes  are  too  scanty  and  our  knowledge 
of  the  Lacandon  Forest,  as  a  whole,  too  slight  to  say  much  about 
the  geographic  affinities  of  the  Laguna  Ocotal  region.  A  number 
of  the  expected  "Guatemalan"  and  "Honduran"  species,  new 
to  the  known  flora  of  Mexico,  were  found,  especially  in  the  rich 
orchid  flora  (Oberg,  in  press).  The  pine  forest  itself  is  rela- 
tively poor  in  distinctive  elements,  but  this  is  perhaps  to  be 
expected  from  its  small  and  discontinuous  area.  It  is  possible 
that  this  ocotal  has  lost  ground  to  the  monte  in  relatively  recent 
times  through  the  occasional  disturbances  caused  by  chicleros, 
anthropologists,  and  others  who  have  used  this  campsite  on  the 
Bonampak  trail.  A  more  long-term  vegetational  change  may  be 
indicated  by  the  pine  logs  found  in  selva  near  Monte  Libano 
(Miranda  1953b).

LAND  AND  FRESHWATER  MOLLUSKS  OF  THE 
SELVA  LACANDONA,  CHIAPAS,  MEXICO 

By 

Joseph  C.  Bequaebt 

To  conform  with  the  general  plan  of  the  reports  on  the  col- 
lections made  by  Dr.  Raymond  A.  Paynter,  Jr.,  and  his  associ- 
ates in  Mexico,  during  the  summer  of  1954,  only  the  39  species 
obtained  in  the  Selva  Lacandona  have  been  fully  treated  below. 
However,  in  order  to  make  the  paper  more  generally  useful,  a 
list  is  appended  of  49  additional  species  definitely  reported  from 
the  State  of  Chiapas.  In  this  list  localities  are  recorded  for  9 
species  obtained  by  Dr.  Paynter 's  party  outside  the  Lacandona 
area.  In  all,  88  species  of  inland  mollusks  are  thus  known  at 
present  from  the  State  of  Chiapas,  73  of  them  terrestrial  and 
15  aquatic. 

As  Chiapas  has  not  been  visited  thus  far  by  a  professional 
malacclogist,  the  88  species  obviously  represent  only  a  fraction 
of  the  actual  molluscan  fauna.  A  comparison  with  the  better 
known  adjoining  areas  of  Mexico  (Veracruz)  and  Guatemala 
(Peten  and  Alta  Vera  Paz),  where  the  ecology  and  topographical 
conditions  are  similar,  suggests  that  the  molluscan  fauna  of 
Chiapas  should  comprise  some  180  to  200  species.  The  known 
88  species  came  from  several  distant  localities  and  were  obtained 
by  different  collectors  during  the  past  100  years.  They  may  be 
regarded  as  a  random  sample  of  at  least  the  more  common  and 
more  conspicuous  forms,  sufficiently  representative  to  determine 
the  dominant  features  of  the  molluscan  fauna  of  the  State,  as 
well  as  of  the  Selva  Lacandona.  It  should  be  kept  in  mind,  more- 
over, that  the  mollusks  of  the  better  explored  adjoining  terri- 
tories are  as  yet  far  from  being  completely  known. 

The  73  terrestrial  species  will  be  considered  first,  as  they 
form  the  bulk  of  the  fauna  and  are  most  interesting  from  our 
point  of  view.  At  present  26  of  them,  or  about  one-third  of  the 
total,  are  known  only  from  Chiapas  or  extend  in  a  few  cases 
just  north  of  the  boundary  to  Tabasco.  Although  this  figure 
seems  to  point  to  a  fairly  higli  degree  of  endemicity,  it  is  prob- 


BIOLOGICAL   INVESTIGATIONS   IN   CHIAPAS,   MEXICO  205 

ably  deceptive.  Several  of  these  "endemic"  species  are  poorly 
known,  often  only  from  single  specimens  and  not  from  one  or 
more  populations.  In  fact  I  am  personally  acquainted  with 
only  eight  of  these  supposedly  endemic  forms.  I  suspect  that 
eventually  many  of  them  will  he  recognized  as  identical  with, 
or  within  the  range  of  intraspecific  variation  of  more  widespread 
species,  recorded  under  other  names  from  adjoining  areas. 

The  largest  group  comprises  28  species  (slightly  over  one- 
third  of  the  total)  which  generally  extend  from  the  western  sec- 
tion of  Veracruz,  through  Tabasco  and  Chiapas,  to  Guatemala 
and  British  Honduras.  Of  these,  15  are  at  present  recorded  from 
Chiapas  (and  sometimes  Tabasco)  to  Guatemala,  9  from  Vera- 
cruz, Tabasco  and  Chiapas,  and  4  from  Veracruz  to  Guatemala ; 
but  there  can  be  little  doubt  that  all  of  them  actuall}7  occur 
throughout  the  whole  area.  As  suggested  above,  this  group  will 
eventually  grow  by  the  addition  of  several  of  the  species  now 
supposedly  endemic  in  Chiapas.  It  appears  to  be  the  dominant 
and  characteristic  molluscan  assemblage  for  what  may  perhaps 
be  called  the  Chiapas-Guatemalan  Subregion  of  Central  America. 
In  all,  54  of  the  73  terrestrial  species  known  from  Chiapas  have 
not  been  recorded  outside  this  Subregion. 

The  remaining  species  are  much  more  widely  distributed.  Most 
of  them  reach  their  northern  limit  in  Veracruz,  although  usually 
extending  southward  far  beyond  Guatemala,  in  some  cases  even 
to  Costa  Rica  and  Panama.  Four  of  them  are  "followers  of 
man,"  who  has  spread  them  far  and  wide  outside  their  original 
home,  which  is  now  sometimes  in  doubt. 

The  very  limited  freshwater  fauna  consists  of  only  15  species. 
As  is  often  the  case  for  freshwater  mollusks  in  the  tropics,  they 
are  not  particularly  characteristic.  Seven  species  are  widely 
distributed  throughout  Mexico  and  Central  America,  or  some 
even  beyond;  5  are  possibly  restricted  to  the  Veracruz-Chiapas- 
Guatemala  area,  like  the  bulk  of  the  terrestrial  species;  and  3 
freshwater  clams  are  at  present  known  only  from  Chiapas,  prob- 
ably due  to  insufficient  knowledge  of  the  Central  American  naiad 
fauna  as  a  whole.

The  30  specimens  from  the  Lacandona  area  agree  well  in 
shape  and  in  sculpture  with  the  descriptions  and  figures  of 
Pilsbry  and  of  Bartsch  and  Morrison.  When  well  preserved,  the 
sculpture  consists  of  microscopic,  spiral,  slightly  wavy,  densely 
crowded  lines  and  coarser  diagonal,  curved  threads,  spirally 
ascending  forward  and  crossing  the  irregular,  vertical  growth 
lines.  The  retractive  threads  are  often  irregular  or  interrupted 
by  coarse  malleations  and  are  usually  best  marked  at  the  peri- 
phery, below  which  they  are  sometimes  nearly  horizontal. 

The  species  was  known  thus  far  from  only  three  specimens. 
The  type  measured  20.7  mm.  in  height,  34  mm.  in  greater  diam- 
eter and  25.9  mm.  in  lesser  diameter.  The  corresponding  figures 
for  the  paratype  were  21.7  mm.,  34.3  mm.  and  26.1  mm.  As  will 
be  seen  from  the  subjoined  table,  some  of  the  22  fully  adult  shells 
of  the  Selva  Lacandona  approach  these  measurements  closely; 
a  few  are  slightly  smaller  (down  to  29.8  mm.  in  greater  diameter 
and  18  mm.  high),  and  several  are  decidedly  larger  (up  to  41.5 
mm.  in  greater  diameter  and  24.7  mm.  high).  The  larger  speci- 
mens seem  to  bridge  the  gap  between  A.  palenquensis  and  A. 
ponderosus  (Pfeiffer),  so  far  as  size  is  concerned.  To  judge  from 
the  specimens  of  A.  ponderosus  at  the  M.C.Z.,  that  species  has, 
however,  a  decidedly  higher  spire  and  a  less  flattened,  more 
convex  body- whorl,  as  well  as  a  deeper  and  somewhat  narrower 
umbilicus,  than  A.  palenquensis.  The  sculpture  seems  to  be 
about  the  same  in  both  species. 

The  specimen  of  A.  ponderosus  figured  by  Bartsch  and  Morri- 
son was  of  about  the  size  of  our  largest  A.  palenquensis.  Other 
known  specimens  are,  however,  much  larger  (up  to  48.5  mm.  in 
greater  diameter  and  29  mm.  high  in  a  series  of  4  specimens  from 
northern  Guatemala  at  M.C.Z.).  It  is  therefore  possible  that 
A.  ponderosus,  definitely  recorded  only  from  Guatemala  (Alta 
Vera  Paz)  and  British  Honduras,  actually  grows  larger  than  A. 
palenquensis.  The  latter  is  known  only  from  northeastern  Chia- 
pas, the  Selva  Lacandona  being  some  70  km.  south  of  Palenque. 

In  general  shape,  measurements,  depressed  spire  and  widely 
open  umbilicus  A.  palenquensis  resembles  Am  phi  cy  clot  us  mega- 
planus  Morrison  (1955,  Proc.  Washington  Acad.  Sci.,  45,  p.  160, 


210  BULLETIN  :  MUSEUM  OF  COMPARATIVE  ZOOLOGY 

figs.  29-31),  from  El  Ocote,  some  35  km.  south  of  Ocozocoautla, 
Chiapas  and  some  180  km.  west  of  the  Selva  Lacandona.  How- 
ever, the  sculpture  of  the  later  whorls  of  megaplanus  is  described 
as  ' '  consisting  of  fine  irregular  axial  vermiculate  ribbing, ' '  being 
similar  to  that  of  Amphieyclotus  texturatus  (Sowerby).  Solem 
suggests  that  megaplanus  may  be  only  a  local  race  of  texturatus.

Laguna  Ocotal,  950  m.,  many  young  shells.   The  largest  meas-

Pomacea  flagellata  (Say)  is  the  common  ampullariid  snail  in 
Mexico  and  Central  America,  from  Veracruz  southward,  as  far 
as  Panama  and  northern  Colombia.  It  is  extremely  variable  in 
shape  and  size  (when  adult),  even  in  the  same  population.  Some 
30  names  have  been  proposed  for  these  variations  and,  as  some 
of  these  have  been  proposed  either  for  unusual  or  freak  speci- 
mens or  for  immature  or  juvenile  snails,  it  is  extremely  difficult 
to  dispose  of  them  as  synonyms  of  the  few  races  or  geographical 
forms  that  may  be  usefully  recognized. 

One  of  the  best  characterized  of  these  races,  seemingly  re- 
stricted to  Tabasco,  Chiapas  and  northern  Guatemala,  is  nearly 
globular  in  shape,  usually  about  as  high  as  its  greatest  width, 
sometimes  slightly  higher  or  slightly  lower.  Under  optimum 
conditions  it  may  reach  greater  dimensions  than  any  of  the  other 
races  of  the  species.  ''Giant"  specimens  are  particularly  com- 
mon in  Lake  Peten,  whence  Tristram  described  his  P.  giganteus. 
The  original  measurements  given  by  Tristram  were :  height, 
95  mm.;  greatest  diameter,  90  mm.;  lesser  diameter,  85  mm.; 
aperture,  66  by  39  mm.  The  cotype  figured  by  von  Martens  is 
92  mm.  high,  with  the  aperture  69.5  mm.  long.  The  largest 
specimen  I  have  seen  from  Lake  Peten  is  102.5  mm.  high,  88  mm. 
in  greatest  width,  with  the  aperture  74.3  by  42  mm.,  of  about  6 
whorls.  The  largest  of  several  collected  by  Mr.  F.  G.  Thompson 
4  miles  south  of  Villahermosa,  Tabasco,  is  83  mm.  high  and  75 
mm.  wide. 


212  BULLETIN  :  MUSEUM  OF  COMPARATIVE  ZOOLOGY 

There  can  be  little  doubt  that  the  type  of  Reeve's  A.  ghies- 
brechtii was  a  slightly  smaller  specimen  of  P.  giganteus  with 
unusually  bright  vermilion  margins  of  the  aperture.  A  brightly 
colored  aperture  occurs  sporadically  in  several  species  of  Poma- 
cea,  but  is  never  a  reliable  specific  character.  The  color  may  be 
more  or  less  pronounced,  and,  moreover,  is  often  more  orange, 
as  in  Fischer  and  Crosse's  figure  of  A.  ghiesbrechtii  from  the 
Usamacinta  River  in  Tabasco  (Miss.  Scientif.  Mexique,  Moll. 
Terr.  Fluv.,  2,  PI.  48,  fig.  8),  where  it  is  present  only  over  the 
outer  margin  of  the  mouth.  Reeve's  figure  of  the  type  of 
ghiesbrechtii  is  85  mm.  high,  73  mm.  in  greatest  width,  with  the 
aperture  59  mm.  by  36.5  mm. 

A.  miltocheilus  Reeve  appears  to  be  no  more  than  a  small 
specimen  of  A.  ghiesbrechtii;  it  was  collected  by  the  same  per- 
son in  Chiapas  also,  and  both  may  have  come  from  the  same 
population.  The  figure  is  48  mm.  high,  43  mm.  in  greatest 
width,  with  the  aperture  36.5  mm.  by  21.5  mm.  The  aperture 
has  the  same  bright  vermilion  color  as  the  type  of  ghiesbrechtii. 

A.  livescens  Reeve  agrees  well  with  some  young  specimens  of 
A.  ghiesbrechtii  found  in  Lake  Peten  with  the  giant  specimens. 
Although  the  name  was  published  some  months  before  ghies- 
brechtii, I  prefer  to  use  the  latter,  because  it  was  based  on  a 
fully  adult  shell  from  a  precise  locality  and  dates  from  the  same 
year.

Laguna  Ocotal,  950  m.,  many  dead  specimens  in  a  silt  deposit 
on  the  shore.  I  have  also  seen  some  fresh  specimens  of  this  re- 
markable snail  from  Lake  Coatepeque,  El  Salvador  (N.  C.  Fassett 
Coll.  —  Received  through  Dr.  H.  "W.  Levi). 

Von  Martens  commented  upon  the  close  similarity  of  subpronus 
and  Taphius  pronus  von  Martens  of  Lake  Valencia,  Venezuela. 
It  is,  indeed,  impossible  to  point  out  a  reliable  difference  in  the 
general  shape,  the  method  of  coiling,  the  degree  of  deflection  of 
the  aperture,  the  shape  of  the  aperture  and  the  relative  width 
and  depth  of  the  umbilicus,  particularly  as  T.  pronus  varies 
greatly  in  all  these  characters.  There  remains  only  the  fine  spiral 
striation  of  the  shell,  present  in  fresh  specimens  of  T.  pronus. 
There  is  no  trace  of  this,  neither  on  the  weathered  specimens 
from  Laguna  Ocotal  (where  they  might  be  worn),  nor  on  the 
very  fresh  specimens  from  Lake  Coatepeque.  The  largest  speci- 
men from  Laguna  Ocotal  is  8  mm.  in  greatest  width  and  2.8  mm. 
thick.  The  largest  of  the  5  specimens  from  Lake  Coatepeque  is 
4.5  mm.  in  greatest  width  and  2  mm.  thick,  approximating  von 
Martens'  original  measurements  of  5  mm.  and  2  mm. 

I  am  not  fully  satisfied  that  F.  C.  Baker's  figures,  cited  above, 
actually  represent  true  T.  subpronus.

Lamellaxis  exiguus   (von  Martens) 
L.eptinaria  exigua   von   Martens,   1898,   Biologia   Centr.-Amer.,   Terr.   Fluv. 
Moll.,  p.  318;  PL  18,  fig.  10  (Teapa  in  Tabasco). 

Laguna  Ocotal,  950  m. ;  Ocosingo,  1000  m. 

As  von  Martens  suspected,  the  original  specimens,  5  mm.  long, 
were  immature.  The  lot  from  Laguna  Ocotal  comprises  three 
immature  shells  agreeing  with  the  original  description  and  figure, 
and  one  adult,  11.2  mm.  long,  5.5  mm.  in  greatest  width,  the 
aperture  5  mm.  by  3  mm.,  of  6y2  whorls;  the  body-whorl  is  7  mm. 
long  in  front  view.  The  spaced,  costulate  sculpture  of  the  earlier 
(post-nepionic)  whorls  changes  gradually  to  close,  finer  vertical 
striae  on  the  later  whorls ;  the  striation  is  replaced  by  exceedingly 
fine  vertical  engraved  lines  below  the  periphery  of  the  body- 
whorl;  the  first  2  (nepionic)  whorls  are  smooth.  In  the  full- 
grown  shell  the  columella  is  shaped  about  as  originally  drawn 
for  the  young,  but  the  median  fold  is  slightly  more  pronounced. 
The  outer  columellar  area  is  broad  and  its  margin  is  spread  over 
the  wide  and  deep  umbilicus. 

The  species  is  known  only  from  Tabasco  and  Chiapas.

Widely  distributed  throughout  tropical  America,  from  Vera- 
cruz to  Sao  Paulo,  Brazil,  and  Peru,  as  well  as  throughout  the 
Antilles.  It  has  possibly  been  spread  by  man.  Pfeiffer 's  original 
locality  appears  to  have  been  erroneous. 

The  species  is  evidently  not  a  true  Opeas  and  I  have  followed 
H.  B.  Baker  (1927,  Occ.  Papers  Mus.  Zool.,  Univ.  Michigan,  No. 
182,  p.  7)  in  placing  it  in  Synopeas  Jousseaume  (1899).  This 
generic  name  appears  to  be  antedated,  however,  by  Synopeas 
Foerster  (1856)  and  a  substitute  may  have  to  be  proposed.

The  specimens  from  Chiapas  agree  with  H.  B.  Baker's  inter- 
pretation of  Morelet "s  II.  trochulina,  which  fortunately  is  in 
accord  with  Morelet 's  type  as  figured  by  von  Martens.  That 
figure  shows  the  body-whorl  even  more  angulate  at  the  periphery 
than  figured  by  Baker. 

Von  Martens  concluded  that  Helix  selenkai  Pfeiffer  (1866) 
could  not  be  separated  from  H.  trochulinus,  whereas  H.  B.  Baker 
regards  them  as  distinct  (although  recognizing  that  they  may 
only  represent  two  ecological  forms).  The  material  before  me 
is  too  small  to  decide  the  matter.  A  lot  of  27  specimens,  from 
the  T.  Bland  Collection,  collected  at  Mirador,  Veracruz,  by 
Berendt,  who  distributed  them  as  //.  selenkai,  appear  to  be  all

very  strongly  marked  (more  so  than  drawn  by  von  Martens)

If  restricted  as  H.  B.  Baker  does,  //.  trochulinus  is  known 
definitely  only  from  Veracruz,  Chiapas  and  Peten.

El  Censo  to  Laguna  Ocotal,  700-1000  m. 

The  five  mostly  adult  specimens  collected  belong  to  the  var. 
hyalino-albida  Fischer  and  Crosse  (1875),  being  clear  whitish, 
although  very  fresh.  Apart  from  color,  they  agree  not  only  with 
the  published  figures  of  Reeve  and  of  Fischer  and  Crosse,  but 
also  with  specimens  from  the  Bland  Collection  (now  at  M.C.Z.), 
labeled  Guatemala. 

There  has  been  some  doubt  about  the  specific  distinctness  of 
D.  moricandi  and  Drymaeus  sulphureus  (Pfeiffer,  1857),  prob- 
ably because  of  the  similarity  in  color  (both  species  having  a 
pure  white  and  a  citron-yellow  phase)  and  the  fact  that  they 
may  occur  together  in  Guatemala.  In  the  series  I  have  compared, 
full-grown  moricandi  differs  consistently  in  being  broader  at 
the  body-whorl,  with  a  wider  spire,  in  the  longer  aperture  (which 
reaches  at  least  half  of  the  total  length  of  the  shell),  in  a  rela- 
tively wider  columellar  area,  and  in  a  more  open  and  perforate 
umbilicus.  Immature  shells  are,  however,  difficult  to  separate. 
The  largest  shell  seen  from  Chiapas  is  29  mm.  long,  14  mm.  in 
greatest  width,  the  aperture  17  mm.  by  9.5  mm. 

D.  moricandi  is  only  known  with  certainty  from  Chiapas  and 
the  adjoining  northeastern  section  of  Guatemala.  D.  sulphureus 
is  more  widely  distributed  from  Veracruz  to  Costa  Rica.

The  species  is  now  for  the  first  time  recorded  from  reliable 
Mexican  localities,  in  Chiapas.  The  supposed  occurrence  in 
"Veracruz"  has  never  been  confirmed  and  was  evidently  one 
more  of  the  many  erroneous  localities  in  the  Cuming  Collection. 
The  record  from  ' '  Honduras ' '  is  likewise  based  on  an  error  from 
the  same  source.  L.  trigonostoma  is  restricted  to  Guatemala  and 
Chiapas,  so  far  as  known  at  present.  Dr.  H.  T.  Dalmat  col- 
lected specimens  in  Guatemala  at  Yepocapa,  Dept.  Chimalten-

The  species  varies  somewhat,  not  only  in  the  banding,  but  also 
in  the  shape  and  slope  of  the  spire.  I  agree  with  Pilsbry  (1899) 
that  it  is  scarcely  useful  to  distinguish  these  variants  by  names, 
except  as  collector's  items.

ANTS  FROM  LAGUNA  OCOTAL  (HYMENOPTERA: 

FORMICIDAE) 

By 

William  L.  Brown,  Jr. 

The  ants  from  Laguna  Ocotal  were  collected  for  the  most  part 
by  Robert  L.  Dressier,  and,  unless  otherwise  indicated,  the  col- 
lections were  made  from  epiphytes,  particularly  bulbous-based 
Tillandsia,  growing  in  the  pine  forest  or  the  adjacent  tropical 
evergreen  forest.  Among  the  21  species  represented  in  the  col- 
lection, 17  can  be  determined  to  species  in  accordance  with 
present-day  classifications;  the  remainder  belong  to  difficult 
groups  in  need  of  revision,  or  else  the  sample  is  in  some  way 
unsatisfactory  for  species  determination,  so  that  identification 
is  carried  only  to  genus. 

All  of  these  species  belong  to  the  tropical  American  fauna, 
and  all  are  either  widespread  in  South  and  Central  America  or 
else  range  at  least  through  Central  America  and  extend  north- 
ward into  Veracruz  and  neighboring  Mexican  states.  Very  few 
ants  have  been  recorded  from  Chiapas  (see  Brown,  1950,  Was- 
mann  Jour.  Biol.,  8:  241-250),  but  with  the  present  series  we 
have  accumulated  a  sample  sufficient  to  confirm  the  expected 
close  similarity  of  the  Chiapas  ant  fauna  to  those  of  Guatemala 
and  Veracruz.  A  few  of  the  records  of  ants  received  from  E.  0. 
Wilson,  collected  by  him  in  Veracruz  during  1953,  are  men- 
tioned below  where  relevant.  I  also  possess  a  small  number  of 
Chiapas  ants  collected  by  C.  J.  Goodnight  and  L.  J.  Stannard 
during  the  last  five  years,  mostly  from  soil  and  leaf-litter  ber- 
lesates,  including  new  species  of  dacetines  and  basicerotines  that 
will  be  described  elsewhere.  The  soil  and  soil-cover  samples  are, 
of  course,  quite  different  from  the  epigaeic-arboreal  collections 
reported  below;  on  the  forest  floor,  Wasmannia  auropunctata 
(Roger),  small  species  of  Pheidole  and  Solenopsis,  Prionopelta 
modesta  Forel,  and  several  of  the  smaller  Dacetini  are  the  com- 
monest forms,  present  in  nearly  every  Berlese  sample  taken, 
while  Pachycondyla  harpax  (Fabricius),  Ponera  nitidula  Emery, 
Ponera  spp.,  and  Brachymyrmex  are  rather  frequent.

As  is  well  known,  some  of  the  forms  listed  below  have  been 
involved  in  considerable  taxonomic  uncertainty,  due  chiefly  to 
unrecognized  synonymy.  "Wherever  such  synonymy  has  become 
obvious  from  the  augmented  samples  now  available  in  the  Mu- 
seum of  Comparative  Zoology,  I  have  taken  the  minimum  formal 
steps  necessary  to  list  and  justify  it. 

Platythyrea  punctata  P.  Smith 

From  a  nest  in  a  fallen  log,  August  3.  Winged  forms  were 
present,  the  males  being  fully  pigmented  and  apparently  active, 
while  most  of  the  females  were  still  in  the  callow  stage  or  were 
not  yet  eclosed.  Wilson  found  this  ant  foraging  on  tree  trunks 
after  dark  in  Veracruz  and  Cuba;  the  nocturnal  tree-climbing 
habit  seems  characteristic  of  many  members  of  tribe  Platythy- 
reini.

This  species  is  very  widespread  in  the  forested  regions  of 
tropical  America,  but  a  single  female  stray  from  a  log  is  the 
first  sample  so  far  recorded  from  Chiapas.  Series  from  different 
nests  from  many  localities  in  the  Museum  of  Comparative 
Zoology  show  wide  diversity  in  size  and  in  allometric  characters, 
including  relative  head  width,  general  robustness  of  body,  and 
sculpture.  However,  there  is  often  considerable  variation  in  these 
characters  within  single  nest  series,  and  one  particular  series, 
from  San  Juan  Pueblo,  Honduras,  leg.  W.  M.  Mann,  contains 
extremes  of  the  variation  as  well  as  all  intergrades ;  bracketed  are 
the  "diagnostic"  characters  for  robustus  and  manco,  as  reviewed 
for  types  and  metatopotypes,  or  both,  of  these  two  variants 
before  me.

Neoponera  lineaticeps  Mayr 

A  small  colony  of  this  rather  uncommonly  collected  ant  was 
taken  from  a  TUlandsia  base,  which  is  apparently  a  preferred 
habitat.  It  has  been  taken  in  Veracruz  and  Costa  Rica  on  several 
occasions,  but  this  is  the  first  record  from  Chiapas.  The  specific 
name  derives  from  the  peculiar  coarse,  regular  longitudinal 
striation  covering  the  central  part  of  the  upper  surface  of  the 
head,  a  feature  that  will  identify  the  species  at  a  glance  under 
magnification.

worker.  NEW  SYNONYMY. 
A  single  worker  was  taken  foraging  on  an  epiphyte.  This 
species  and  the  closely  related  N.  obscuricornis  Emery  have  been 
confused  through  the  literature,  and  the  confusion  extends  to 
most  of  the  ant  collections  rich  in  neotropical  material  to  this 
day.  The  outstanding  differences  between  these  two  species  as 
I  see  them  are  :  ( 1 )  N.  apicalis  has  the  five  or  six  apical  funicular 
segments  a  bright,  contrasting  yellow,  whereas  in  N.  obscuri- 
cornis,  the  apex  of  the  funiculus  is  little  or  not  at  all  lightened, 
and  does  not  form  a  sudden  contrast  with  the  rest  of  the  antenna. 
Faded  or  teneral  specimens  may  seem  to  be  intermediate,  but 
these  are  rare  and  are  easily  identified  by  the  remaining  charac- 
ters. (2)  N.  apicalis  has  the  sides  of  the  petiolar  node  nearly 
flat,  scarcely  or  not  at  all  concave  or  sulcate  just  next  to  the 
posterolateral  angles,  so  that  these  angles  are  blunt,  whereas 
in  obscuricornis,  the  same  angles  are  thrown  into  relief  by  a 
slight  but  distinct  sulcation  extending  along  the  posterior  sides 
of  the  node  from  top  nearly  to  base.  (3)  Of  the  two  species, 
apicalis  is  slightly  but  distinctly  larger  on  the  average,  though 
there  is  some  overlap  in  size  between  the  two  forms.  (4)  JV.  api- 
calis is  more  opaquely  sculptured  than  is  N.  obscuricornis,  though 
both  species  are  strongly  opaque;  direct  comparison  is  really 


BIOLOGICAL  INVESTIGATIONS   IN   CHIAPAS,   MEXICO  231 

needed  to  reveal  the  difference.  A  study  of  numerous  nest 
series,  in  addition  to  stray  workers,  convinces  me  that  the  fore- 
going characters  are  consistently  linked  in  one  or  the  other 
combination.  No  difficulty  has  arisen  in  assigning  fresh  worker 
specimens  to  one  or  the  other  species,  and  no  intergrades  have 
been  seen,  despite  the  fact  that  the  two  species  frequently  occur 
in  close  proximity  over  a  vast  area  reaching  from  the  Amazon 
Basin  to  southern  Mexico.  In  the  Museum  of  Comparative 
Zoology,  collections  of  both  species  at  single  localities  have  been 
made  as  follows :  Kartabo  and  Kamakusa,  British  Guiana,  leg. 
W.  M.  Wheeler;  Barro  Colorado  I.,  Panama  Canal  Zone,  leg.  N. 
Banks;  Laguna  Encantada,  Veracruz,  leg.  Q.  Jones  and  R.  L. 
Dressier ;  Pueblo  Nuevo,  near  Tetzonapa,  and  Las  Hamacas,  near 
Santiago  Tuxtla,  both  in  Veracruz,  leg.  E.  0.  Wilson.  Both 
species  live  in  plant  cavities  in  arboreal  situations,  but  nothing 
has  been  recorded  concerning  their  ecological  occurrence  in  any 
detail. 

While  it  seems  clear  enough  that  two  and  only  two  species 
exist  in  this  complex,  the  application  of  names  to  these  entities 
is  still  in  some  doubt.  The  earliest  recognized  description  of  a 
member  of  the  complex  appeared  when  Latreille  claimed  to  have 
described  two  species  at  once,  giving  them  the  names  flavicornis 
and  apicalis.  The  former  name  was  supposed  by  Latreille  to 
apply  to  a  Formica  flavicornis  earlier  named  by  Fabricius,  but 
Fabricius'  insect  is  apparently  an  attine  species  having  nothing 
to  do  with  Neoponera;  flavicornis  is  thereby  a  preoccupied  name. 
Nearly  everything  about  Latreille 's  characterization  of  flavi- 
cornis and  apicalis  is  either  confused  or  patently  in  error,  and 
the  confusion  extends  to  the  correspondence  of  the  plate  figures 
with  their  respective  descriptions.  No  reliable  difference  is 
mentioned  or  shown  by  Latreille  that  will  serve  to  separate  the 
two  forms,  and  the  description  of  the  antennal  coloration,  if 
nearly  accurate,  would  indicate  that  both  are  referable  to  apicalis 
in  the  present  sense.  This  is  my  interpretation,  made  without 
recourse  to  types,  but  a  thorough  examination  of  the  original 
references  in  conjunction  with  fairly  good  samples  of  the  com- 
plex shows  that  it  is  the  simplest  solution  to  a  problem  that 
bothered  Latreille,  Emery,  and  Wheeler,  among  others,  to  the 
point  where  the  essentially  simple  species-to-species  relationship 
became  lost  to  view.  The  name  latreillei  is  an  objective  synonym 


232  BULLETIN  :  MUSEUM  OP  COMPARATIVE  ZOOLOGY 

of  flavicornis.  I  do  not  follow  Emery's  "Genera  Insectorum" 
assignment  of  latreillei  as  a  variety  of  obscuricornis  —  an  as- 
signment which  expressed  his  lack  of  confidence  in  latreillei  as 
a  named  entity  in  his  characteristically  mild,  but  in  this  case 
totally  confusing,  fashion.  The  variety  verenae  was  described 
by  Forel  in  his  familiar  "final  melange"  paper  of  1922,  in  which 
several  other  formicid  variants,  since  synonymized  by  various 
authors,  were  named  on  the  basis  of  the  most  doubtful-appearing 
evidence.  Forel  mentions  no  character  that  would  serve  to  dis- 
tinguish verenae  from  typical  apicalis,  and  verenae  comes  from 
the  middle  of  the  range  of  the  species.

Wheeler  conceived  the  named  variants  above   (plus  also  the 
"subspecies"  sulcatula  Santschi,  q.v.  infra,  which  belongs  in  the 
crenata,  not  the  unidentata,  complex)  as  "local  varieties"  based 
on  differences  in  color,  sculpture,  form  of  petiole,  pilosity  and 
some  lesser  details.    There  is  no  doubt  that  variation  exists  in 
these  various  features,  and  it  is  clear  that  both  Emery  and 
Wheeler  understood  that  the  variation  was  graded  from  series 
to  series  even  in  the  limited  samples  examined  by  these  authors. 
It  is  also  clear,  from  the  present  augmented  sample  drawn  from 
many  parts  of  the  species  distribution,  that  the  different  charac- 
ters do  not  vary  according  to  the  same  geographic  plan.    The 
region  of  the  Upper  Amazon  Basin  shows  the  strongest  varia- 
tion, especially  in  sculpture,  and  the  range  of  the  variation  there 
leaves  little  encouragement  for  racemakers.   While  it  is  possible 
to  trace  some  series  to  their  general  area  of  origin  by  the  study 
of  trends  in  individual  characters,  other  samples  are  ambiguous 
or  contradictory  in  the  display  of  the  same  characters.    Clearly, 


BIOLOGICAL  INVESTIGATIONS  IN   CHIAPAS,   MEXICO  233 

a  study  of  geographical  variation  by  individual  characters  is 
required  before  further  attempts  are  made  to  classify  the  popula- 
tions making  up  N.  unidentata. 

At  the  Laguna  Ocotal  collecting  area,  the  species  is  character- 
ized in  general  by  a  petiolar  node  a  bit  less  thick  from  front  to 
rear,  as  viewed  from  the  side,  than  in  the  average  Amazonian 
series.  However,  I  am  unable  to  separate  some  samples  in  the 
Chiapas  lot  from  some  taken  in  the  Amazon-Guianas  region. 
According  to  the  locality  and  the  characteristics  of  the  most 
extreme  examples,  I  suppose  the  Chiapas  series  would  fall  under 
Wheeler's  concept  of  var.  may  a.  This  species  is  common  in 
bulbous-based  Tillandsia  at  the  Laguna,  if  Dressier 's  collections 
are  a  fair  indication  of  relative  abundance. 

N.  unidentata  and  N.  crenata  (Roger),  and  also  N.  carinulata 
(Roger),  range  widely  over  tropical  America.  All  three  inhabit 
plant  cavities,  and  all  are  very  similar  in  general  habitus,  but 
the  types  of  petiolar  node  formation  are  widely  divergent. 

Neoponera  crenata  (Roger) 

Ponera  crenata  Roger,  1861,  Berlin,  eut.  Zeitschr.,  5:  3,  female,  nom.  pro 
Portera  pallipes   Fr.   Smith,   1858,  p.   98  nee  p.   87. 

The  series  from  Laguna  Ocotal  (and  most  collected  else- 
where in  southern  Mexico)  agree  best  with  the  form  described 
by  Forel  as  X.  stipitum,  of  which  a  cotype  rests  in  the  Museum 
of  Comparative  Zoology.  For  the  present,  I  am  unable  to  find 
any  satisfactory  characters  to  separate  stipitum  from  crenata, 
and  I  incline  to  the  belief  that  a  thorough  study,  with  resort  to 
the  scattered  types  of  these  and  other  named  variants  of  the 
complex,  will  see  them  all  merged  under  the  name  crenata. 
Meanwhile,  we  may  tentatively  associate  various  morphological 
tendencies  with  the  names  attached  to  the  several  inadequate 
descriptions  involved. 

The  populations  of  which  I  have  samples  vary  widely  in  size 
from  nest  to  nest,  although  intranidal  variation  is  relatively  re- 
stricted. Weakly  correlated  with  size  is  the  shape  of  the  petiolar 
node ;  this  correlation  holds  best  at  the  extremes  of  the  size  range, 
but  is  poor  in  intergradient  series.  Larger  specimens  (ca.  11  to 
12.5  mm.  in  TL,  or  total  outstretched  length  of  body,  including

throughout,  and  distinct  from  the  dorsal  face,  and  the  compound 
eyes  tend  to  be  farther  from  the  front  of  the  sides  of  the  head, 
e.g.,  Kartabo,  British  Guiana,  nos.  60,  425,  leg.  W.  M.  Wheeler. 
These  correspond  to  my  idea  of  "typical"  crenata  (=pallipes 
F.  Smith  preocc). 

In  smaller  specimens,  such  as  the  Wheeler  Kartabo  series  nos. 
495,  708,  679,  286,  507,  671,  148  and  621,  among  many  others, 
TL  averages  only  6  to  8  mm.  In  these,  the  eyes  may  be  closer 
to  the  anterior  cephalic  margins  and  the  posterior  nodal  face  is 
often  (not  always)  more  convex,  with  the  surface  curving  con- 
tinuously into  the  dorsal  face;  such  specimens  correspond  to 
stipitum  Forel.  It  is  worth  noting  that  the  female  node,  as  usual 
among  ponerines,  is  higher  and  thinner  in  lateral-view  profile 
than  in  the  workers  from  the  same  nest.  This  caste  difference 
appears  to  have  caused  some  confusion  in  the  complex  in  the 
past. 

A  specimen  from  Espiritu  Santo,  Brazil  (TL  8.8  mm.)  and 
some  others  away  from  the  Kartabo  locality  appear  to  be  transi- 
tional between  the  large  and  small  forms,  but  this  would  not 
necessarily  preclude  the  specific  distinction  between  two  closely 
related  forms  where  sympatric,  as  at  Kartabo  and  elsewhere  in 
the  Amazon-Orinoco  Basins  (perhaps  a  case  of  "character  dis- 
placement"). The  intermediate  forms  seem  to  be  the  same  as 
moesta  Mayr,  the  var.  moesta  of  authors.  The  polynomials  N. 
crenata  fiebrigi  Forel,  N.  crenata  confusa  Santschi,  N.  crenata 
confusa  lata  Santschi  and  N.  unidentata  sulcatula  Santschi  seem 
from  their  descriptions  to  represent  minor  southern  nest  variants 
in  the  small-to-medium  size  range  of  the  crenata  complex;  these 
names  are  almost  sure  to  prove  synonymous  when  properly 
studied.  In  view  of  the  insufficiency  of  my  present  sample 
(though  it  is  considerably  better  than  exists  in  other  collections 
known  to  me)  and  the  difficulty  of  seeing  all  the  types  involved, 
I  have  left  formal  synonymy  in  this  group  to  some  future 
worker. 

ECITON    BURCHELLI    (WestWOOd) 

Workers  were  taken  from  a  raiding  column  near  the  Laguna 
Ocotal  camp.  These  specimens  would  undoubtedly  be  placed  as 
"race  paririspinum"  by  Father  Borgmeier;  however,  the  head 


BIOLOGICAL  INVESTIGATIONS  IN   CHIAPAS,   MEXICO  235 

of  the  largest  major  (soldier)  in  the  series  is  dingy  yellowish- 
white  in  color. 

PSEUDOMYRMEX  PALLIDUS  F.  Smith 

A  few  workers  from  a  Tillandsia. 

Pseudomyrmex  gracilis  (Fabricius) 

This  is  the  common  bicolored  form  of  the  species  often  known 
as  var.  or  subsp.  mexicanus.  It  may  be  that  the  bicolored  form 
is  suppressed  in  northern  South  America  where  other  bicolorous 
species  of  similar  size  and  appearance  become  common.  The 
geographical  variation  of  this  complex,  while  outstandingly  con- 
spicuous, has  never  been  carefully  and  thoroughly  investigated. 

Pheidole  punctatissima  Mayr 
Two  colonies  were  taken  in  epiphytic  plants. 

Pheidole  spp. 

Two  indeterminate  species  of  Pheidole  were  taken  in  Tilland- 
sia. One  of  these  is  in  the  confusing  biconstricta  group,  and  the 
other  is  a  much  smaller  species.  Pheidole  is  one  of  the  very 
large  (1,000-plus  named  forms)  ant  genera  currently  "out  of 
control"  taxonomically.  Until  adequate  revisions  of  these  groups 
become  available,  description  of  isolated  new  species  only  adds  to 
the  confusion  and  the  unrecognized  synonymy.  Possibly  one  half 
of  the  names  currently  remaining  unchallenged  in  Pheidole  are 
synonyms  of  older  names,  and  identification  of  species  with  any 
certainty  is  hopeless  in  most  faunas,  even  where  helpful  pre- 
liminary revisionary  attempts  have  been  published. 

Procryptocerus  scabriusculus  Emery 

A  stray  worker  from  foliage.  E.  0.  Wilson  also  took  a  worker 
during  1953  at  Las  Hamacas,  near  Santiago  Tuxtla,  Veracruz. 
This  and  the  following  two  cephalotine  species  were  determined 
from  revisionary  papers  on  the  cephalotines  by  W.  W.  Kempf. 
The  work  of  Father  Kempf  is  refreshingly  sound  and  useful  as 


236  BULLETIN  :  MUSEUM  OF  COMPARATIVE  ZOOLOGY 

compared  to  the  majority  of  publications  on  neotropical  ants 
with  which  the  would-be  identifier  has  to  grapple. 

Paracryptocerus  cristatus  (Emery) 

A  stray  soldier.  E.  0.  Wilson  took  a  colony  of  this  species  at 
Las  Hamacas,  Veracruz,  on  August  27,  1953,  occupying  three 
internodes  of  a  living  Cecropia  tree  about  15  feet  tall  in  tropical 
evergreen  forest. 

Paracryptocerus  scutulatus  (F.  Smith) 

A  soldier  aud  workers.  The  species  is  widespread  from 
southern  Mexico  to  Venezuela. 

Smithistruma  epinotalis   (Weber) 

This  little  dacetine  normally  lives  in  plant  cavities  well  above 
the  ground.  The  collection  at  Laguna  Ocotal  was  made  from  a 
Tillandsia,  but  collections  from  Veracruz,  sent  by  N.  L.  H. 
Krauss  and  by  E.  0.  Wilson,  were  taken  from  hollow  twigs  of 
standing  shrubs  and  trees. 

Acromyrmex  octospinosus  (Reich) 

Foraging  workers  of  this  fungus-growing  ant  stole  rice  from 
the  Laguna  Ocotal  camp.  The  species  has  been  discussed  at 
length  by  W.  M.  Wheeler  (1937,  "Mosaics  and  other  anomalies 
among  ants,"  Harvard  Univ.  Press.  Cf.  pp.  69-74),  who  detailed 
the  ambiguity  of  the  characters  supposed  to  separate  it  from 
A.  hystrix  (Latreille).  Wheeler  suggested  as  a  better  separatory 
character  the  presence  or  absence  of  bilateral  tubercles  or  carinae 
on  the  propodeal  dorsum;  however,  Wheeler's  own  series  of  the 
two  forms  in  the  Museum  of  Comparative  Zoology  appear  to 
grade  through  on  this  basis  without  a  break. 

The  distinction  of  the  "races"  echinatior  Forel,  inti  Wheeler, 
volcanus  Wheeler,  ekchuah  Wheeler  and  cubanus  Wheeler  seems 
to  me  at  least  as  precarious  as  the  specific  separation  of  hystrix 
from  octospinosus.  The  differences  supposed  to  separate  these 
forms  are  weak  and  variable,  and  seem  to  mark  mere  individual 
or  nest  varieties  in  some  eases ;  even  if  they  prove  later  to  follow 


BIOLOGICAL  INVESTIGATIONS  IN   CHIAPAS,   MEXICO  237 

to  some  degree  geographical  trends,  there  seems  little  to  be  gained 
by  placing  formal  names  upon  these  samples  at  this  time.  As 
seems  to  be  the  case  with  a  large  number  of  the  subspecies  so 
far  described  in  the  animal  kingdom,  these  examples  are  based  on 
entirely  inadequate  samples  from  restricted  localities,  and  in 
their  description  scant  thought  seems  to  have  been  given  to  the 
overaU  trends  in  variation  of  the  characters  within  the  whole 
species. 

Azteca  sp. 
A  small  brownish  form,  represented  by  minor  workers  only. 

Brachymyrmex  obscurior  Forel 

Specimens  from  TiUandsia  seem  to  agree  best  with  descriptions 
and  other  determined  material  of  this  species,  though  determina- 
tions in  this  genus  are  doubtful  in  the  absence  of  anything 
better  than  Santschi's  revision. 

Nylanderia  ?guatemalensis  (Forel) 

This  slender  yellowish  form  is  usually  placed  as  a  subspecies 
of  vivid  ul  a,  but  since  the  taxonomy  of  this  genus  is  so  poorly 
worked  out,  I  feel  that  it  is  better  to  accord  provisional  spe- 
cies rank  to  those  names  not  obviously  synonyms.  The  guati  - 
))iale7isis  syntype  in  the  Museum  of  Comparative  Zoology  is 
badly  damaged,  rendering  the  comparison  uncertain.

FISHES  FROM  LAGUNA  OCOTAL 

By 

Robert  Rush  Miller1 

Since  no  special  collecting  equipment  was  available,  only  a 
very  limited  sample  of  the  fish  fauna  of  this  lake  was  obtained. 
Forty-seven  specimens,  representing  four  species  in  three  fam- 
ilies, were  secured  by  dipnet,  bent  pin,  and  rifle  (using  .22  caliber 
dust  shot)  between  July  21  and  August  14,  1954,  by  various 
members  of  the  expedition.  Many  of  the  examples  are  twisted, 
with  broken  fins  and  missing  scales,  thus  rendering  a  careful 
study  difficult  or  impossible.  One  viviparous  species  cannot  be 
identified  with  certainty  to  genus  since  no  males  were  obtained. 
Although  two  new  species  appear  to  be  represented,  no  suitable 
type  material  is  available  and  further  well-preserved  series,  in- 
cluding both  sexes,  are  needed  to  clarify  their  status.  The  fol- 
lowing report,  therefore,  is  necessarily  of  a  preliminary  nature. 

The  specimens  listed  below  have  been  divided  between  the 
Museum  of  Comparative  Zoology  and  the  Museum  of  Zoology 
of  the  University  of  Michigan. 

Despite  the  small  size  of  the  collection,  a  most  interesting 
fish  fauna  is  indicated  for  Laguna  Ocotal.  Isolation  no  doubt  has 
been  a  potent  factor  in  the  differentiation  of  endemic  species  in 
this  remote  area. 

CHARACIDAE 

Characins 

Astyanax  fasciatus  (Cuvier).  Banded  tetra. 

This  is  one  of  the  widest  ranging  freshwater  fishes  of  the 
Americas.  It  is  known  from  Argentina  northward  on  the  At- 
lantic slope  to  western  Texas  and  adjacent  parts  of  New  Mexico, 
and  on  the  Pacific  slope  from  Colombia  to  western  Mexico  (Rio 
Armeria  basin  of  Colima  and  Jalisco).

BIOLOGICAL  INVESTIGATIONS   IN   CHIAPAS,    MEXICO  239 

There  are  10  adults,  59  to  107  mm.  in  standard  length.  The 
number  of  anal  fin-rays  varies  as  follows:  22(4),  23(4),  and 
24(2).  Recognition  of  subspecies  of  A.  fasciatus  is  currently 
made  largely  on  the  basis  of  the  anal-ray  count.  The  above 
specimens  could  be  assigned  to  A.  f.  aeneus  (Giinther)  or  they 
might  be  interpreted  as  intergrades  between  that  lowland  form 
and  the  highland  subspecies,  A.  f.  mexicanus  (de  Filippi).  I 
prefer  to  postpone  assignment  until  a  good  series  is  available 
from  Laguna  Ocotal,  especially  since  these  specimens  have  a 
more  oblique  mandible  and  more  posterior  dorsal  fin  than  speci- 
mens of  A.  f.  aeneus  from  the  Usumacinta  basin  in  Guatemala. 

The  following  color  notes  were  made  in  Ann  Arbor  on  October 
29,  1954.  The  fins  of  the  three  largest  fish  (98,  105  and  107  mm. 
S.L.)  are  bright  yellow-orange  to  deep  red-orange  as  follows: 
over  seven-eighths  of  the  pelvic  fins  (tips  of  rays  clear),  the 
anteriormost  9  rays  to  all  of  the  rays  of  the  anal  fin,  the  outer 
one-half  of  the  caudal  rays  (except  3  to  4  rays  of  each  lobe,  which 
are  colored  their  entire  lengths),  and  the  median  part  of  the 
pectoral  rays  (weakly  colored).  The  dorsal  fin  is  clear  in  one, 
faintly  yellowish  on  the  distal  half  in  another,  and  yellow-orange 
on  the  same  rays  in  the  third.  The  seven  smaller  fish  show  weaker 
color  on  these  fins  or  none  at  all. 

POECILIIDAE 

Livebearers 

PSEUDOXIPHOPHORUS  BIMACULATUS  (Heckel) 

This  species  is  known  along  the  Atlantic  slope  of  Middle 
America  from  Veracruz,  Mexico,  to  Miranda,  Nicaragua ;  its  alti- 
tudinal  distribution  is  from  near  sea  level  to  about  3,500  ft. 

Twenty-three  young  to  adult  specimens,  16  to  49  mm.  long,  in- 
cluding 3  mature  males,  were  obtained.  The  scale  crescents  are 
conspicuously  blackened.  Dorsal-ray  counts  are  as  follows:  13(3), 
14(12),  and  15(8).  According  to  current  practice,  this  sample 
is  assignable  to  P.  b.  taeniatus  Regan  (see  Hubbs,  1935,  Univ. 
Mich.  Misc.  Publ.  No.  28:  9-10,  and  references  cited  therein),  a 
subspecies  known  to  range  from  Mexico  to  Honduras. 


240  BULLETIN  :  MUSEUM  OF  COMPARATIVE  ZOOLOGY 

Undetermined  genus  and  species. 

There  are  2  adult  females  of  a  species  of  poeciliid  which  I 
cannot  identify  with  any  known  member  of  the  family.  In  the 
absence  of  males,  T  am  uncertain  to  which  genus  the  species 
belongs.  Reference  to  the  Poeciliidae  (rather  than  to  some  other 
cyprinodont  family)  is  assured  from  the  nature  of  the  first  3  rays 
of  the  anal  fin  (unbranched)  and  of  the  neuromasts  or  pit  organs 
on  the  scale  rows  (see  Hubbs  and  Miller,  1954,  Zoologica,  39 
(1):2). 

The  general  body  form  is  similar  to  that  of  Lucania  parva 
(Baird  and  Girard),  a  species  of  the  oviparous  family  Cyprino- 
dontidae,  although  it  is  more  angulate  anteriorly,  both  in  dorsal 
and  ventral  profiles.  The  dorsal  fin  is  long,  containing  12  rays 
in  each  specimen;  the  anal  fin  has  9  rays.  The  origin  of  the 
dorsal  fin  is  midway  between  the  base  of  the  caudal  fin  and  the 
tip  of  the  snout.  There  is  a  faint,  dark  line  along  the  midside 
of  the  body  that  fades  out  anteriorly,  and  the  skin  beneath  the 
anterior  half  of  the  exposed  part  of  each  scale  on  the  back  and 
sides  shows  a  concentration  of  coarse  chromatophores.  There  are 
no  distinctive  markings. 

The  mandible  is  short  and  nearly  vertical,  indicating  a  surface- 
feeding  habit.  The  teeth  are  distinctive :  those  in  the  outer  row 
of  each  jaw  are  large  and  asymmetrical  (shaped  like  the  tip  of  a 
tableknife  blade),  and  are  tilted  obliquely  away  from  the  center 
towards  the  outer  margin  of  the  jaws;  they  are  most  strongly 
oblique  nearest  the  midpoint  of  each  jaw,  becoming  almost  erect 
at  the  margins.  There  is  a  toothless  gap  at  the  midpoint  in  the 
lower  jaw.  Inside  of  each  outer  row  of  teeth  is  an  irregular 
series  of  small,  conical  teeth. 

The  body  shape,  long  dorsal  fin,  oblique  mouth,  and  distinctive 
dentition  comprise  characters  which  set  this  species  apart  from 
any  poeciliid  known  to  me  from  Middle  America.  The  jaw  denti- 
tion of  Xiphophorus  helleri  (Heckel)  is  very  similar  and  the 
species  in  question  may  pertain  to  that  genus ;  it  does  not  repre- 
sent that  species,  however,  which  differs  in  coloration,  mouth 
width,  a  less  oblique  lower  jaw,  the  more  robust  body,  etc.  The 
dentition  of  the  outer  jaws  is  similar  also  in  specimens  of  Phalli - 
chthys  pittieri  (Meek),  but  the  teeth  of  that  species  are  more 
loosely  attached  and  more  numerous  and  other  marked  differences 
indicate  no  intimate  relationship.

CICHLIDAE 

Mo  j  arras 
Cichlasoma  species 

Twelve  specimens,  51  to  96  mm.  long,  represent  a  species  of 
(he  "Section"  (or  subgenus)  Parapetenia  of  Regan  (1906,  Biol- 
ogia  Centrali-Americana,  Pisces,  8 :  26).  However,  I  cannot  place 
the  present  form  with  any  of  those  treated  by  Regan  or  by  sub- 
sequent authors.  What  remains  of  the  color  pattern  is  suggestive 
of  both  C.  salvini  and  C.  iirophthalmus,  but  the  Ocotal  specimens 
otherwise  differ  in  many  ways  from  both  of  those  species.  There 
are  rather  definite  to  indistinct  vertical  to  oblique  bands  along 
the  sides,  numbering  not  more  than  10  or  11,  the  anteriormost 
2  to  3  extending  obliquely  forward  across  the  nape  (as  in  C. 
nigrofasciatum) .  An  irregular,  usually  disrupted,  lateral  band 
extends  from  the  upper  angle  of  the  opercle,  reaching  backward 
not  farther  than  to  below  the  middle  of  the  soft  dorsal  fin.  Some 
specimens  have  a  prominent  black  spot  at  the  base  of  the  upper 
half  of  the  caudal  fin  (and  lying  entirely  above  the  posterior 
extension  of  the  lateral  line)  which  is  surrounded  by  a  light 
area,  as  in  C.  urophthalmus  (see  Giinther,  1868,  Trans.  Zool.  Soc. 
London,  6:  PI.  72,  fig.  1)  ;  this  spot  is  indistinct  or  obsolete  in 
other  specimens.  The  two  largest  fish  are  entirely  black  (a  mel- 
anistic  phase?)  and  have  a  shorter  pectoral  fin  (not  reaching 
origin  of  anal),  but  otherwise  agree  with  the  ten  smaller  fish. 
In  the  latter,  the  pectoral  fin  extends  to  above  or  slightly  beyond 
the  origin  of  the  first  anal  spine.  It  is  possible  that  the  two  black 
specimens  represent  a  different  species,  but  this  point  cannot  be 
determined  satisfactorily  on  the  basis  of  the  present  material. 

The  spinous  dorsal  is  long  and  low,  comprising  18  spines  in 
9  and  19  in  3  specimens;  the  soft  dorsal  has  9  rays  in  all;  the 
anal  spines  are  numerous :  8  in  7  and  9  in  5 ;  and  the  soft  rays  of 
the  anal  fin  vary  as  follows:  6(1),  7(7),  8(3),  and  9(1).  A 
narrow  but  definite  frenum  is  present  in  each  specimen  and  the 
gillrakers  (total  number,  including  rudiments)  number  9(1), 
10(9),  and  11(2).  The  premaxillary  spines  extend  posteriorly 
from  about  the  front  to  the  middle  of  the  orbit. 

The  large  number  of  dorsal  and  anal  spines  (with  correspond- 
ingly few  soft  rays),  the  body  form,  and  the  coloration  appear 
to  be  among  the  distinguishing  characters  of  this  species.

REPTILES  AND  AMPHIBIANS  FROM 
THE  SELVA  LACANDONA 

By 

Benjamin  Shreve 

As  this  section  of  the  report  deals  only  with  the  reptiles  and 
amphibians  collected  during  1954  in  the  Selva  Lacandona,  it 
is  perhaps  fitting  to  mention  that  Raymond  A.  Paynter,  Jr.  and 
Robert  L.  Dressier  collected  reptiles  and  amphibians  in  other 
parts  of  Chiapas  and  elsewhere  in  Mexico.  Although  not  included 
in  this  study,  these  are  much  appreciated. 

Of  those  collected  in  Chiapas,  a  specimen  of  Stenorhina  f. 
freminvillii  Dumeril,  Bibron  and  Dumeril  from  Ocosingo,  should 
be  mentioned  as  representing  the  first  record  of  this  race  for  the 
state.  It  will  be  seen  that  of  those  species  discussed  in  the 
report,  several  are  new  to  Mexico  or  to  Chiapas. 

It  seems  advisable  to  mention  that  the  wholesale  restriction  of 
type  localities  by  Smith  and  Taylor  (1950,  Univ.  Kansas  Sci. 
Bull.,  33,  pp.  313-380)  is  not  followed  here  because  of  the  numer- 
ous instances  of  error  and  poor  judgment,  aside  from  being  con- 
sidered unnecessary.  See  comments  of  Dunn  and  Stuart  (1951, 
Copeia,  p.  55;  and  1951,  Science,  113,  p.  677).

a  differently  colored  dewlap,  smaller  ventrals  as  compared  with 
the  dorsals,  and  possibly  larger  head  scales.  These  are  mentioned 
by  the  two  authors  of  this  new  form  as  differences  between  their 
new  race  and  the  typical  form.

cal form.

distinguishing  their  Chiapas  material  from  the  rest  of  their 
Mexican  toads,  although  they  referred  all  to  Bufo  horribilis 
Wiegmann.  These  authors  fail  to  state  how  horribilis  differs  from 
the  several  other  forms  that  undoubtedly  have  been  included  in 
what  is  conventionally  regarded  as  marinus,  whose  type  locality 
was  probably  Surinam.   Head  and  body  length  150  mm.

Trinomials  are  used  as  conspicuus  is  probably  just  the  southern 
representative  of  alf  recti.  The  differences  between  the  two  forms 
appear  to  be  very  slight.  Although  the  type  locality  of  con-

laticeps  (1932,  Bull.  U.  S.  Nat.  Mus.,  160,  pp.  93,  106),  which 
was  taken  from  the  unique  type.  Kellogg  does  not  mention  the 
length  of  the  tarsal  fold,  which  in  our  material  extends  from 
about  one-half  to  two-thirds  the  length  of  the  tarsus.  The  entire 
underside  of  the  lower  jaw  and  throat,  not  just  the  sides  of  the 
throat  as  in  the  type,  is  stippled  Avith  brown.  In  one  specimen 
(M.C.Z.  28246)  the  usual  black  side  of  the  upper  jaw  is  reduced 
to  a  spot  under  the  eye. 

The  largest  example  (M.C.Z.  28227)  has  a  head  and  body 
length  of  78  mm.  The  much  larger  size  of  laticeps  and  its  some- 
what different  coloring  seem  to  be  the  chief  characters  separating 
it  from  the  closely  related  Central  American  E.  gollmeri 
(Peters).  But  in  color  gollmeri  sometimes  shows  the  same  varia- 
tion as  is  described  above  for  M.C.Z.  28246.

the  forelimbs,  the  anterior  border  being  nearly  straight;  head 

and  body  length  41  mm.  Although  known  from  Piedras  Negras,

The  largest  of  these  unquestionably  belongs  to  this  race.  The 
two  smaller  examples  (M.C.Z.  28218-9)  are  less  certain.  They  do 
not  show  the  reticulation  or  spotting  on  the  limbs  and  sides  dis- 
played by  the  large  specimen. 

This  constitutes  the  first  Mexican  record  for  both  the  species

BIRDS  OF  LAGUNA  OCOTAL 

By 

Raymond  A.  Paynter,  Jr. 

INTRODUCTION 

An  investigation  of  the  avifauna  was  one  of  the  primary  ob- 
jectives of  the  Museum  of  Comparative  Zoology  expedition  to  the 
Selva  Lacandona,  Chiapas.  Between  July  21  and  August  19, 
1954,  while  at  Laguna  Ocotal  (alt.  950  m.),  490  birds  were  pre- 
pared as  skins.  While  these  specimens  are  a  good  sample  of 
the  resident  avifauna,  there  can  be  little  doubt  that  additional 
species  occur  in  the  region  but  were  not  observed.  In  a  heavily 
forested  region  collecting  is  difficult  even  under  the  most  favor- 
able conditions.  We  were  at  work  at  the  end  of  the  breeding 
season  when  most  birds  are  silent  and  secretive  -  obviously  the 
most  difficult  collecting  period. 

The  following  list  is  based  on  the  specimens  collected,  as 
well  as  on  unequivocal  field  observations.  The  specimens  were 
weighed  on  a  double-pan  balance.  The  means  of  the  measure- 
ments are  accompanied  by  their  standard  errors  (am)-  The 
Hippoboscidae  (bird-flies)  were  identified  by  Joseph  C.  Bequaert. 

ANNOTATED  LIST 

Tinamus  major  robustus  Sclater  and  Salvin 

1  $  ,  Aug.  7. 
The  species  was  heard  on  a  few  occasions  and  seen  twice.   The 
bird  weighed  1090.5  grams. 

Crypturellus  boucardi  boucardi  (Sclater) 

1  9  ,  July  22 ;  1$,  Aug.  10 ;  1$,  Aug.  11. 

Although  by  no  means  common,  this  is  the  more  abundant 
tinamou.  Occasionally  it  was  found  in  the  tropical  evergreen 
forest  but  it  occurred  principally  in  the  monte.  The  males 
weighed  291.4  and  403.3  grams;  the  female  351.0  grams.

On  an  undisturbed  lake  one  would  expect  to  find  water  birds 
in   abundance,    but   the    cormorant    was   the    only    exclusively 
aquatic  form  and  even  they  were  in  small  flocks.   The  weight  of 
the  bird  was  1165.0  grams. 

Butorides  viRESCENS  virescens  (Linnaeus) 

1$,  Aug.  11. 

The  specimen  is  immature  and  weighed  93.1  grams.    Green 
Herons  were  uncommon. 

Sarcoramphus  papa  (Linnaeus) 

One   was   observed,   within   a   flock   of   Turkey   Vultures,   on 
August  3. 

Cathartes  aura  subsp. 
A  few  vultures  came  to  the  camp  at  irregular  intervals. 

Elano'ides  forficatus  subsp. 
Two  kites  were  noted  on  Julv  26  and  three  on  August  1. 


i&  ■ 


Accipiter  striatus  subsp. 

A  single  individual  flew  back  and  forth  over  the  lake  on 
August  16.  It  would  seem  an  early  date  for  a  migrant.  Prob- 
ably the  bird  was  a  resident,  possibly  A.  s.  chionogaster. 

Buteogallus  urubitinga  ridgwayi  (Gurney) 

1  £  ,  Aug.  15. 

This  is  the  only  example  of  the  species  which  was  seen.  It 
harbored  three  species  of  Hippoboscidae :  Omithociona  erythro- 
cephala,  Lynchia  angustifrons,  and  L.  wolcotti. 

I  concur  with  Amadon  (1949),  and  Amadon  and  Eckelberry 
(1955),  that  the  genera  Hypomnrphnus  and  Buteogallus  should 
lie  united.

Laughing  Falcons  were  heard  several  times. 

MlCRASTTJR  SEMITORQUATUS  NASO   (LeSSOn) 

1$,  Aug.  17. 
Although  the  dense,  undisturbed,  forests  surrounding  the 
lake  appeared  ideally  suited  for  certain  of  the  birds  of  prey, 
such  as  those  of  the  genera  Micrastur,  Spizastur,  and  Spizaetus, 
hawks  were  excessively  rare.  Only  one  example  of  M.  semitor- 
quatus  was  seen.  It  was  host  to  the  bird-flies  Omithoctona 
erythrocephala  and  Lynchia  wolcotti,  and  weighed  749.8  grams. 

Micrastur  ruficollis  guerilla  Cassin 

1  (J ,  Aug.  14. 
The  specimen  was  taken  in  the  low  forest  near  the  edge  of 
the  lake.   On  several  occasions  others  were  found  in  the  thickest 
parts  of  the  evergreen  forest. 

Falco  rufigularis  subsp. 

On  August  10  a  pair  of  Bat  Falcons  flew  near  the  (.'amp. 
where  they  could  be  seen  distinctly. 

Crax  rubra  rubra  Linnaeus 

U,  19,  Aug.  8;  1$,  Aug.  15. 

Curassows  were  fairly  abundant  but  not  so  numerous  as 
guans.  The  specimen  collected  on  August  15  is  about  one-third 
grown. 

Penelope  purpurascens  purpurascens  Wagler

Chachalacas  were  very  abundant  in  the  transition  zone  between 
the  broadleaf  forest  and  the  pines,  and  in  the  monte  at  the  end 
of  the  lake.  Specimens  of  Ornithoctona  erythrocephala  were 
obtained  from  four  birds  and  Lynchia  plaumanni  from  one.  Six 
males  ranged  in  weight  from  319.1  to  448.5  grams,  with  a  mean 
of  402.30±16.82;  nine  females  from  309.6  to  394.8,  with  a  mean

Aram  us  guarauxa  dolosus  Peters 

19,  Aug.  1;  19,  Aug.  11. 
There  seems  to  be  no  specific  record  of  the  species  in  Chiapas, 
although  Alvarez  del  Toro  (1952)  mentions  that  it  is  abundant 
in  the  state.  The  shores  of  the  lake  are  strewn  with  the  empty 
shells  of  the  snail  Pomacea  flagellata,  the  preferred  food  of 
limpkins,  suggesting  the  presence  of  many  of  these  birds.  How- 
ever, none  was  heard  and  just  a  few  lone  individuals  were  seen. 

Aramides  cajanea  subsp. 

A  wood  rail  called  in  the  evening  of  July  30.  This  is  another

which  was  inexplicably  rare.

small  kingfisher,  but  somewhat  slower.  The  male  is  an  adult  and 
weighed  49.0  grams.  The  female  retains  a  portion  of  the  im- 
mature plumage  and  weighed  40.5  grams.  Elsewhere  (Paynter,

Short-billed  Pigeons  were  heard  frequently,  and  sometimes 
could  be  seen  in  the  tallest,  trees  of  the  broadleaf  forest.  The 
specimens,  however,  were  taken  principally  in  the  low  forest  and 
edges  where  they  came  to  feed  in  fruiting  trees. 

The  males  weighed  154.3,  154.4.  159.0,  and  166.1  grams;  the

1  <5  ,  July  22 ;  15.  July  2.5  ;  1  $ ,  July  30  ;  16,  July  31. 

Although  the  species  has  been  recorded  in  Mexico  only  from 
Santa  Kosa,  Comitan,  Chiapas  (Berlioz,  1939)  and  from  two 
localities  on  the  Rio  Usumacinta  in  Tabasco  (Brodkorb,  1943), 
it  was  reasonably  abundant  in  the  deep  forest  at  Laguna  Ocotal. 
The  apparent  absence  of  Leptotila  verreauxi  and  L.  plumbeiceps, 
species  which  are  widely  distributed  in  southern  Mexico,  was 
surprising.  However,  most  forms  of  Leptotila  are  secretive  and 
difficult  to  collect  and  I  would  feel  certain  of  the  absence  of 
these  species  only  if  more  time  had  been  spent  in  the  field. 

Two  adult  males  and  a  female  weighed  167.2,  176.5,  and  152.1 
gram,  respectively;  a  female  in  juvenal  plumage  138.0  grams. 

Ara  macao  (Linnaeus) 

Small  flocks  of  Scarlet  Macaws  flew  over  quite  regularly  in

then  only  in  the  tops  of  tall  pines  or  on  conspicuous  dead  trees 
in  the  selva.

PlONUS  SENILIS  SENILIS  (Spix) 

1$,  Aug.  14;  1$,  Aug.  16. 

Although  parrots  passed  over  each  day  at  dawn  and  dusk, 
they  were  nearly  absent  from  the  forest  surrounding  Laguna 
Ocotal.  Late  in  our  stay  a  small  flock  of  Pionus  senilis  began 
to  roost  for  the  night  in  the  pines  at  the  edge  of  the  broad- 
leaf  forest  on  the  eastern  side  of  the  lake.  It  is  from  this 
group  that  the  specimens  were  secured.  The  birds  weighed  220.4 
and  221.5  grams. 

The  genus  Amazona  was  represented  in  the  flocks  of  parrots 
seen  in  the  air.  A.  ochrocephala  was  tentatively  identified,  but 
another  species  seemed  to  be  present  also ;  there  may  have  been 
still  others.

Phaethornis  superciliosus  longirostris  (DeLattre) 

1  9  ,  July  31;  1  8  ,  Aug.  9. 
No  approach  to  P.  s.  veraecrucis  is  exhibited  by  the  specimens, 
although  birds  from  Palenque,  which  is  about  100  kilometers  to 
the  north,  either  were  referred  to  that  race  (Brodkorb,  1943, 
Tashian,  1952)  or  said  to  be  intermediate  (Friedmann,  Griscom, 
and  Moore,  1950).  The  weight  of  the  male  was  6.4  grams;  that 
of  the  female  5.9  grams.  Dressier  reported  seeing  one  of  these 
hummingbirds  feeding  at  a  dwarf  Heliconia  {H.  tortuosa 
Griggs),  a  plant  with  red  bracts  and  long,  curved,  yellow 
flowers,  for  which  the  bird's  bill  is  well  suited.

This  species  and  the  females  and  immature  males  of  Abeillia 
abeillei  were  impossible  to  differentiate  in  the  field ;  their  relative 
abundance  is  not  known.  Among  the  least  common  humming- 
birds, they  occurred  in  the  high  broadleaf  forest  in  localities 
where  the  sun  reaches  the  ground  and  encourages  the  growth 
of  flowering  plants  and  shrubs.

Mt.  Ovando,  Chiapas,  the  type  locality  of  L.  v.  ovandensis,  and 
conclude  that,  although  recognizahle,  it  is  an  extremely  weak 
race.  The  coloration  of  the  dorsal  surface  is  variable  and  no 
consistent  difference  between  the  two  races  is  distinguishable. 
The  bill  length  is  also  inconstant;  there  appears  to  be  a  com- 
plete overlap  between  the  forms  in  this  character.  The  only  dif- 
ferentiating features  I  can  appreciate  are  the  faintly  lighter 
abdomen  and  slightly  greater  area  of  white  on  the  lower  throat 
of  L.  v.  ovandensis. 

Seven  males  ranged  in  weight  from  5.3  to  6.5  grams,  with

Trogon  collaris  puella  Gould

Within  the  heavy  forest  this  species  was  noted  with  regularity, 
but  it  was  uncommon. 

The  males  weighed  63.7  and  64.5  grams ;  the  females  63.4 
grams.  It  is  of  interest  to  compare  these  weights  with  those 
obtained  on  the  Yucatan  Peninsula  (Paynter,  1955).  There  two 
males  weighed  47.6  and  53.5  grams,  and  two  females  41.1  and 
53.9  grams.  This  suggests  that  the  Peninsular  birds  are  smaller 
in  mass,  although  no  differences  in  linear  measurements  are 
evident.    A  larger  series  is  needed  to  confirm  the  proposal.

These  small  motmots  were  seldom  seen,  but  because  of  their 
silent,  sluggish  behavior  may  have  been  more  numerous  than  it 
appeared. 

The  two  males  weighed  32.5  and  32.7  grams;  the  female  29.7 
and  the  bird  of  doubtful  sex  31.0  grams.  None  possessed  more 
than  a  trace  of  fat.  Van  Tyne  (1935)  gave  the  weight  of  five 
males  from  Peten  as  ranging  from  27.0  to  28.5  grams,  and 
noted  that  the  heaviest  bird  was  fatty ;  two  females  weighed  26.5 
and  27.5  grams.  The  apparent  difference  in  weight  between  the 
two  populations  should  be  investigated  when  more  data  are 
available.

No  more  than  ten  of  these  birds  were  seen  during  the  period

considerably  heavier  than  the  previously  reported  maximum 
of  119.5  grams  (Van  Tyne,  1935). 

Tashian  (1952)  listed  M.  m.  goldmani  from  Palenque,  but

Centurus  pucherani  perileucus  (Todd) 

1  9  ,  July  29 ;  1  <$ ,  Aug.  IS  ;  19,  Aug.  19. 

Within  the  pines  this  species  was  moderately  numerous,  but 
it  usually  ranged  in  the  tops  of  the  trees,  out  of  gunshot.  One 
of  the  specimens  was  collected  in  the  pines  and  the  other  two 
in  the  zone  of  transition  between  the  pine  and  broadleaf  forests. 
It  was  rare,  however,  in  the  latter  locality.  The  weight  of  the 
male  was  53.0  grams;  that  of  the  females  48.9  and  49.4  grams. 

Amadon  and  Eckelberry  (1955),  in  commenting  on  the  failure 
of  many  authors  to  unite  Centurus  with  Melanerpes,  as  was 
done  by  Peters  (1948),  state  that  "...  the  barred  (sic)  imma- 
ture plumage  of  the  Red-headed  Woodpecker  (M.  erythrocepha- 
lus)  and  the  color  pattern  of  M.  portoricensis,  do  tie  the  two 
groups  together. ' '  I  fail  to  appreciate  this.  The  plumage  of  the 
immature  M.  erythrocephalus  is  streaked,  not  barred,  and  notably 


BIOLOGICAL  INVESTIGATIONS   IN   CHIAPAS,    MEXICO  259 

similar  to  that  of  the  adult  Acorn  Woodpecker  {M.  formici- 
vorus).   No  species  of  Centurus  approximates  such  a  condition. 

M.  portoricensis,  an  insular  species  presumably  at  the  end 
of  an  evolutionary  line,  rather  than  a  link,  bears  no  resemblance 
to  the  Centurus  group,  with  the  exception  of  its  red  abdomen  and 
brown  sides.  Dorsally  it  is  similar  to  M.  formicivorus  with  a 
glossy  black  back,  white  rump,  and  white  forehead ;  it  lacks 
only  the  red  head  of  that  species  (and  of  Centurus) .  Its  behavior 
is  said  to  be  like  that  of  the  Acorn  Woodpecker  (Wetmore, 
1927).  The  coloration  of  the  throat  and  upper  chest  of  M. 
portoricensis  is  similar  to  that  of  M.  erythroceplialus,  even  to 
the  remnant  of  a  black  pectoral  band.  The  extension  of  red  to 
the  abdomen,  when  the  chest  is  red,  is  a  small  evolutionary  step 
and  is  certainly  a  logical  explanation  for  the  existence  of  this 
character  in  M.  portoricensis. 

Thus,  the  only  real  similarity  between  this  species  and  the 
Centurus  group  is  the  brown  coloration  of  the  sides.  It  seems 
most  likely  that  this  character  was  acquired  independently  by 
an  M.  forinicivorus-liiie  progenitor,  which  was  isolated  in  the 
Antilles.  Alternative  explanations  are  that  M.  portoricensis  is 
a  primitive  species  exhibiting  the  first  indications  of  the  diver- 
gence of  Centurus  from  Melanerpes,  or,  that  Centurus  is  the 
older  group  and  M.  portoricensis,  retaining  only  its  brown 
sides,  betrays  the  origin  of  Melanerpes.  These  are  obviously 
spurious  hypotheses. 

It  is  unexpected  that  Amadou  and  Eckelberry  (1955)  should 
accept  the  unification  of  Centurus  and  Melanerpes,  but  main- 
tain Tripsurus,  a  genus  also  reduced  to  the  synonymy  of  Mela- 
nerpes by  Peters  (1918).  It  is  true  that  the  species  usually 
placed  within  Tripsurus  are  separated  from  Centurus  (sensu 
stricto)  by  gaps  greater  than  those  existing  between  most  species 
of  Centurus,  but  I  believe  the  group  is  not  of  generic  rank  and 
is  best  considered  a  subgenus  of  Centuries.

Two  males  weighed  33.8  and  35.5  grams.  Both  species  of 
Dendrocincla  were  present  in  moderate  numbers  and  seemed 
about  as  common  as  I  have  found  them  in  the  rain  forest  of 
the  Yucatan  Peninsula. 

Sittasomus  griseicapillus  sylvioides  Lafresnaye

The  linear  dimensions  of  8.  g.  sylvioides  and  8.  g.  gracileus 
have  been  shown  to  be  markedly  different  (Paynter,  1955).  It 
is  not  unexpected  that  a  substantial  difference  in  the  average 
weight  of  the  races  also  can  be  demonstrated.  The  weight  of 
five  males  of  8.  g.  sylvioides  from  Laguna  Ocotal  ranged  from 
12.8  to  14.2  grams,  with  a  mean  of  13.52±0.21;  that  of  six 
females  from  11.1  to  13.8  grams,  with  a  mean  of  12.53±0.12. 
On  the  Yucatan  Peninsula,  where  8.  g.  gracileus  is  found,  seven 
males  ranged  from  9.0  to  12.1  grams,  with  a  mean  of  11.01±0.35; 
four  females  from  8.6  to  10  grams,  with  a  mean  of  9.25±0.34 
(Paynter,  1955). 

Within  the  selva  this  was  the  most  abundant  of  the  Dendro- 
colaptidae.

Dendrocolaptes  certhia  sancti-thomae  (Lafresnaye) 

1  9  ,  July  26  ;  1  9  ,  Aug.  9;  1  $ ,  Aug.  13. 

A  bird  of  the  high  evergreen  forest,  but  at  times  seen  on  the 
trunks  of  pines  when  they  were  adjacent  to  its  preferred  habitat. 
No  woodhewer  was  more  shy. 

When  more  birds  have  been  weighed  there  may  be  evident  a 
difference  in  mass  between  this  subspecies  and  D.  c.  legtersi 
of  the  Yucatan  Peninsula.  The  male  and  the  two  females 
weighed,  respectively,  67.3,  66.0,  and  68.3  grams.  Tashian 
(1952)  found  a  female  to  weigh  63.0  grams.  Paynter  (1955) 
recorded  two  males  of  D.  c.  legtersi  as  weighing  52.7  and  60.8 
grams,  and  three  females  of  D.  c.  sancti-thomae,  which  exhibited 
an  approach  toward  the  Yucatan  Peninsula  endemic,  as  54.3,

L.  of/in  is  and  the  present  species  occurred  sympatrically  in 
the  pines.  They  are  morphologically  so  similar  it  was  not  possible 
to  distinguish  them  in  the  field ;  their  relative  abundance  is  un- 
known.  As  an  aggregate,  however,  they  were  not  common. 

An  adult  male  and  two  females  weighed  30.8.  29.8,  30.9  grams,

It  is  regrettable  that  it  was  not  possible  to  study  the  species 
carefully  while  in  the  field.  L.  souleyetii  is  a  lowland  form  which 
usually  occurs  in  rain  forest,  while  L.  affinis  is  found  in  pines  or

other  types  of  forest  characteristic  of  the  highlands.  The  fact 
that  at  Laguna  Ocotal  L.  souleyetii  abandoned  the  broadleaf 
forest  for  the  pines  suggests  that  it  may  have  found  a  more 
easily  exploitable  niche  within  the  conifers.  Neither  species  was 
common  and  probably  they  were  able  to  exist  sympatrically 
without  competing. 

The  specimen  weighed  27.6  grams.

None  of  the  Furnariidae  was  more  abundant  than  this  species, 
which  was  a  conspicuous  element  of  the  heaviest  selva. 

Seven  males  ranged  in  weight  from  44.7  to  50.4  grams,  with  a

These  birds  were  seen  on  the  average  of  about  once  a  day  in 
the  most  dense  forest.  The  weight  of  the  male  and  three  females

fauna. At  Laguna  Ocotal,  it  was  common,  and  often  associated 
with  Myrmotherula  schisticalor,  in  the  shrubs  bordering  trails 
through  the  thickest  parts  of  the  deciduous  forest. 

Three  of  the  males  are  immature  and  weighed  11.6,  12.7,  and

PORMICARIUS  ANALIS  MONILIGER  Sclater 

IS,  Aug.  18. 

Antthrushes  were  noted  only  four  times  but  undoubtedly 
were  more  abundant  than  it  seemed.  On  the  Yucatan  Peninsula 
I  found  them  exceedingly  difficult  to  collect  during  the  wet  sea- 
son, but  when  the  forest  was  dry  they  were  heard  moving  about 
in  the  leaves,  much  like  tinamous,  and  could  be  taken  with  little 
difficulty.  The  specimen  from  Laguna  Ocotal  was  snared  in  a 
trammel  net  in  the  monte,  although  previously  the  species  had 
been  seen  only  in  the  high  forest.   It  weighed  51.3  grams.

One  of  the  females  collected  on  August  16  is  a  fledgling  barely 
able  to  fly.  This  species  is  among  the  latest  breeders  found  in  the 
region  and  also  was  one  of  the  most  common  birds  wherever  there 
were  bushes  and  small  trees  in  the  broadleaf  forest.  Adult  males 
made  up  about  one  quarter  of  the  birds  seen. 

Adult  males  weighed  17.8  17.9,  and  19.1  grams;  an  immature 
male  15.8  grams;  adult  females  1 6.6,  17.1,  17.2,  and  17.4  grams;  a

Myiarchus  tuberculifeb  connectens  Miller  and  Griscom 

U,  July  20;  1  9  ,  Aug.  5 ;  1  $  ,  Aug.  10;  2  ?,  Aug.  12;  1  $  ,  Aug.  18. 

The  specimens  from  Laguna  Ocotal  are  referable  to  M.  t. 
connectens,  although  they  are  rather  small  and  fall  within  the 
upper  size  range  of  a  series  of  24  specimens  of  M.  t.  platyrhyn- 
chus,  the  smallest  of  the  races,  from  the  Yucatan  Peninsula. 
They  are,  however,  dark  dorsally  and  have  varying  amounts  of 
rufous  on  the  underside  of  the  rectrices,  two  characters  dis- 
tinguishing M.  t.  connectens  from  M.  t.  platyrhynchus.  The  race 
seems  not  to  have  been  reported  from  Chiapas,  although  it  is  to 
be  expected  along  the  northern  and  northeastern  Guatemalan 
border. 

Recently  (1955)  I  noted  that  one  character  distinguishing  M. 
tuberculifer  from  M.  yucatanensis  is  its  horn-colored,  rather  than 
black,  bill.  It  was  not  realized  at  the  time  that  the  lighter  colored 
bill  is  not  always  found  in  M.  tuberculifer.  M.  t.  connectens  and 
M.  t.  lawrenceii  occasionally  have  horned-colored  bills,  but  in  the 
vast  majority  it  is  black.  On  the  other  hand,  within  the  remain- 
ing races  horn-colored  bills  are  frequent  and  black  bills  are  some- 
what of  an  exception;  only  M.  t.  platyrhynchus,  and  apparently 
M.  t.  nigricapillus,  seem  to  have  consistently  light  bills. 

Enough  data  have  accumulated  so  that  a  slight  difference  in 
weight  between  several  races  seems  to  be  evident.  Six  males 
of  M.  t.  platyrhynchus  ranged  from  14.7  to  19.7,  with  a  mean 
of  17.15±0.74  grams;  females  of  the  race  weighed  15.0,  16.0, 
17.3,  and  17.9  grams  (Paynter,  1955).  31.  t.  connectens  has  larger 
linear  dimensions  and  the  specimens  from  Laguna  Ocotal  sug- 
gest that  heavier  weight  may  be  an  added  character.  Three  males 
weighed  19.0,  19.9,  and  19.2  grams,  a  female  19.2  grams,  and 
two  birds  of  undertermined  sex  18.0  and  19.1  grams.  M.  t. 
lawrenceii,  the  race  with  the  greatest  linear  dimensions  of  the 
three,  may  also  weigh  the  most.  Paynter  (1955)  recorded  males 
from  Ocozocoautla,  Chiapas  as  weighing  21.8  and  22.5  grams; 
Martin,  Robins,  and  Heed  (1954)   found  males  in  Tamaulipas

of  the  range  for  X.  y.  centralis,  as  given  by  Paynter  (1955).  All 
the  specimens  are  worn  or  in  molt;  it  is  possible  that  in  fresh 
plumage  there  would  be  less  overlap  with  X.  y.  centralis. 

Two  males  weighed  72.1  and  87.1  grams ;  five  females  from 
84.0  to  88.0  grams,  with  a  mean  of  86.08±0.68. 

Jays  occurred  commonly  in  the  selva.  They  were  present,  but 
less  abundant,  in  the  pines  and  monte.

It  is  probable  that  T.  m.  umbrinus  and  T.  m.  canobrunneus 
may  be  distinguishable  by  a  difference  in  weight.    At  Laguna 
Ocotal,  six  males  ranged  from  16.0  to  18.7  grams,  with  a  mean 
of  16.76 ±0.47  ;  five  females  from  13.4  to  15.4  grams,  with  a  mean 
of   14.44±0.46.    On   the   Yucatan  Peninsula    (Paynter,   1955), 
seven  males  ranged  from  13.3  to  15.0  grams,  with  a  mean  of 
14.36±0.77;  11  females  from  11.9  to  12.8  grams,  with  a  mean  of 
11.90±0.95. 

These  wrens  ranged  through  the  low  forest  in  abundance. 
Occasionally  they  were  found  in  the  high  broadleaf  forest  and 
in  the  brush  at  the  edge  of  the  pine  zone.

Troglodytes  musculus  ixtermedius  Cabanis 

1  6  .  July  28  ;  1  $ ,  Aug.  2  ;  19.  Aug.  3  ;  1  $  ,  Aug.  17. 

In  the  scrubby  pine  burn  the  species  was  common,  but  it  was 
one  of  the  most  difficult  birds  to  collect  because  of  its  excessively 
shy  nature. 

At  Ocosingo,  where  one  specimen  (male  ?)  was  collected 
on  July  8,  and  at  El  Real,  where  a  female  and  male  were  taken 
on  July  13  and  14,  the  species  lived  in  the  vicinity  of  houses 
and  behaved  like  its  northern  counterpart,   T.  aedon. 

The  weights  of  the  males  were  11.1,  11.2,  11.4,  and  12.0  grams; 
those  of  the  females  10.6  and  10.6  grams.

A  very  abundant  resident  of  the  undergrowth  in  the  broad- 
leaf  forest. 

Seven  adult  males  weighed  between  14.4  and  17.3  grams, 
with  a  mean  of  15.81±.32;  five  females  from  14.1  to  16.7  "rams, 
with  a  mean  of  15.40±.41. 

Hexicorhixa  leucopiirys  castaxea  Ridgway 

1  9,  July  2.->;  1  .$,  Aug.  2. 

These  specimens  apparently  represent  the  first  record  of  H.  I. 
castanea  from  Mexico,  although  Hellmayr  (1934)  had  predicted 
that  it  would  be  found  there  on  the  Atlantic  slope.  The  respective 
weights  of  the  male  and  female  were  16.6  and  16.1  grams. 

H.  Jeucophnjs  and  //.  leucosticta  were  found  in  what  seemed 
to  be  exactly  the  same  habitat.  No  behavioral  differences  were 
noted.  The  darker  breast  of  H.  leucophrys  could  not  -be  recog- 
nized in  the  dark  undergrowth,  making  it  impossible  to  dis- 
tinguish between  the  two  species.  They  were,  therefore,  collected 
at  random.  Presumably  the  ratio  between  the  species  in  the 
collection  also  represents  the  true  ratio  at  Laguna  Ocotal.

MlCROCERCULUS  MARGINATUS  PHILOMELA  (Salvin) 

1  ?,  July  26.;  1  $  ,  Aug.  9. 

There  is  no  doubt  that  this  wren  was  uncommon  but  it  was 
by  no  means  rare,  as  the  dearth  of  specimens  would  seem  to 
indicate.  Its  call  is  distinctive  and  was  heard  about  once  a  day 
while  collecting  in  the  broadleaf  forest.  It  was  seldom  seen 
because  of  its  preference  for  the  darkest  areas  of  the  forest 
floor,  where  it  blended  ideally  with  the  background. 

The  male  weighed  18.1  grams ;  the  unsexed  bird  18.4  grams. 

TURDUS  ALBICOLLIS  LEUCAUCIIEN  Sclater 

19,  July  28;  1$,  Aug.  14. 

The  male  retains  the  juvenal  plumage  on  its  throat,  upper 
breast,  wing  coverts,  neck,  and  pileum.  The  remainder  of  the 
plumage  is  slaty  with  a  faint  wash  of  olive.  The  other  bird, 
an  adult  female,  is  decidedly  olivaceous  dorsally ;  the  throat 
markings  are  brownish  black.  It  agrees  with  specimens  of  T.  a. 
leucauchen  from  Guatemala. 

The  weight  of  the  male  was  66.7  grams ;  that  of  the  female 
70.3  grams. 

Myadestes  unicolor  pallens  Miller  and  Griscom 

1$,  July  31;    16,  Aug.  1;    19,  Aug.  7;   29,  Aug.  11;   19,  Aug. 
12;  IS,  Aug.  15;  1$,  Aug.  18. 

The  type  of  M.  u.  veraepacis,  56  specimens  of  M.  u.  pallens 
from  Honduras  and  Nicaragua,  one  specimen  from  Veracruz  and 
three  from  "Mexico"  of  M.  u.  unicolor,  and  the  present  series 
from  Chiapas  have  been  examined.  It  is  concluded  that  M.  u. 
pallens  is  barely  distinguishable  from  the  nominate  form,  on 
the  basis  of  its  paler  ventral  color,  and  that  31.  u.  veraepacis, 
which  was  described  as  an  intermediate  form,  is  referable  to 
M.  u.  pallens.  The  supposed  differences  in  size  between  the  forms 
cannot  be  confirmed  with  the  present  material. 

Because  this  is  a  montane  species,  it  is  presumed  that  the 
population  north  of  the  Isthmus  of  Tehuantepec  has  no  contact 
with  that  which  occurs  from  Chiapas  southward.  It  is,  there- 
fore, not  surprising  that  the  series  from  Laguna  Ocotal  is 
referred   to   the   more   southern   population,  M.   u.   pallens.    It 


BIOLOGICAL  INVESTIGATIONS   IN   CHIAPAS,    MEXICO  271 

is  strange,  however,  that  the  species  does  not  subspeciate  more 
markedly,  since  it  is  a  member  of  a  genus  whose  species  are 
rather  plastic. 

Adult  males  weighed  34.1  and  38.2  grams;  an  adult  female 
36.1  grams;  two  males  and  a  female  which  were  in  almost  com- 
plete adult  plumage  39.5,  40.7,  and  36.3  grams,  respectively.

Berlioz  (1939)  recorded  the  species  from  Chiapas  for  the 
first  time,  but  lacking  comparative  material  was  unable  to  assign 
his  series  to  a  race. 

The  beautiful  song  of  this  thrush  was  often  heard  in  the 
late  afternoon  and  sometimes  in  the  morning.  It  must  have  been 
fairly  abundant,  but  it  was  very  difficult  to  approach.  Had  it 
not  been  for  the  song,  it  would  have  been  assumed  to  be  a  rare 
species.  It  was  collected  in  the  darkest  parts  of  the  broadleaf 
forest. 

A  young,  spotted  female  weighed  29.0  grams;  two  females 
which  were  not  quite  adult  31.9  and  32.6  grams ;  two  adult  males 
and  an  adult  female  33.1,  37\5,  and  32.6  grams,  respectively. 

Smaragdolantus  pulchellus  pulchellus  (Sclater  and  Salvin) 

1  9  ,  Aug.  3 ;  1  $ ,  Aug.  12 ;  1  $  ,  Aug.  13. 

Alvarez  del  Toro  (1952)  has  recorded  this  species  in  Chiapas, 
apparently  for  the  first  time.  Blake  (1953)  also  lists  the  bird 
from  there  but  has  informed  me  (in  lift.),  that  his  citation 
of  the  race  8.  p.  verticalis  from  Chiapas  is  a  lapsus. 

Being  a  species  which  ranges  in  the  tops  of  trees  it  is  difficult  to 
judge  its  abundance.  It  seemed  to  be  uncommon.  The  male 
weighed  25.3  grams;  the  females  24.3  and  26.2  grams.

Prior  to  Alvarez  del  Toro's  book  (1952)  the  species  does  not 
seem  to  have  been  noted  from  Chiapas.  It  was  common  at  Laguna 
Ocotal  in  the  broadleaf  forest.

Mniotilta  varia  (Linnaeus)

PARULA  AMERICANA  INORNATA  Baird 

19,  Aug.  12. 

Parula  "pitiayumi"  appears  to  be  only  a  morphologically  pro- 
nounced subspecies  group  of  P.  americana.  Unless  sympatry  can 
be  shown  to  exist,  the  logical  course  seems  to  be  to  treat  the 
groups  as  conspecific. 

A  pair  of  the  warblers  was  in  a  flowering  tree  in  the  montc 
on  August  12.   No  others  were  seen  while  at  the  lake. 

The  specimen  weighed  6.9  grams,  as  did. a  female  collected  at 
Ocosingo  on  July  7.

1  9  ,  July  22 ;  1$  ,  July  30  ;  1  ?,  Aug.  ]8  ;  2  <5  ,  Aug.  19. 

The  species  was  abundant  in  the  tops  of  the  pines.  It  was 
noted  in  the  broadleaf  forest  a  few  times. 

The  specimens  exhibit  no  approach  toward  D.  g.  ornata,  a 
distinctive  form,  which  has  been  found  in  western  Cbiapas  (e.g.. 
Edwards  and  Lea,  1955)  but  for  which  there  seems  to  be  no 
published  report  in  eastern  Chiapas.  In  the  Museum  of  Com- 
parative Zoology  there  are,  however,  specimens  referable  to  this 
race  from  Santa  Rosa  (Escuintla)  and  Nuevo  Amatenango, 
localities  near  the  Guatemalan  border. 

The  respective  weights  of  three  males  and  a  female  were  7.3, 
8.5,  8.7  and  7.6  grams.  One  bird  was  host  to  the  hippoboscid 
Ornithoctona  fusciventris.

at  the  rate  of  about  one  per  clay.    The  specimen  collected  on 
July  25  is  a  very  early  arrival,  but  at  Palenque  in  1949  Tashian 
(1952)  observed  the  species  on  July  12.

grams. 


Granatellus  sallaei  sallaei  (Bonaparte) 

19  ?,  Aug.  10;  1&,  Aug.  13. 

A  rare  inhabitant  of  the  low  forest  at  the  end  of  the  lake. 
The  male  weighed  14.0  grams,  suggesting  that  this  race  is  heavier 
than  G.  s.  boucardi,  six  males  of  which  are  known  to  have 
ranged  from  9.2  to  10.6  grams,  with  a  mean  of  10.00±.22  (Payn- 
ter,  1955).  The  bird  whose  sex  could  not  be  determined  with 
certainty  weighed  11.6  grams. 

I  have  examined  the  type  of  6?.  s.  griscomi  van  Rossem,  a 
male,  and  find,  as  the  describer  claimed  (1934),  that  dorsally 
it  is  less  slaty  and  gray  than  most  specimens  of  the  species.  The 
supposed  differences  in  the  distribution  and  shade  of  the  red  of 
the  underparts,  and  of  the  gray  on  the  throat,  cannot  be  recog- 
nized by  me. 

The  bird  was  received,  as  a  mount,  by  the  Museum  of  Com- 
parative Zoology  in  1880.  It  is  presumed  to  have  been  collected 
at  least  a  few  years  earlier.  It  was,  therefore,  well  over  fifty 
years  old,  at  a  minimum,  when  named  as  the  type.  It  is  soiled 
and  has  the  oily  texture  that  is  often  noticed  in  specimens  which 
have  been  mounted  and  on  display  for  many  years.  The  charac- 
ters ascribed  to  the  race  are  without  doubt  functions  of  age  and 
dirt.  This  belief  is  strengthened  when  old  and  fresh  specimens 
of  G.  s.  boucardi,  or  of  G.  s.  sallaei,  are  compared.  The  older 
specimens  are  often  noticeably  darker.

1$,  July  26. 
These  were  among  the  most  abundant  birds  at  the  lake.    They 
occurred  in  all  types  of  habitat,  with  the  exception  of  the  pines, 
although  they  were  most  often  found  in  the  higher  broadleaf 
forest. 

Females  weighed  8.8,  10.0,  10.3,  and  10.4  grams ;  two  males 
9.8  grams  each. 

Basileuterus  rufifrons  salvini  (Cherrie) 

1    ?,  July   14;    19,  July  20;    IS,  July  23;    IS,  19,  Aug.   12. 

This  species  replaced  B.  culicivorus  in  the  pines,  where  it  was 
common  but  usually  too  high  to  collect.  Two  males  weighed  11.4 
and  11.8  grams;  two  females  10.3  and  10.8  grams. 

Todd  (1929)  and  Griscom  (1932)  to  the  contrary,  it  appears 
that  Ridgway  (1902)  was  correct  in  treating  delattrii,  salvini, 
and  rufifrons  as  conspecific.  Griscom  (1932)  chose  to  regard 
each  as  a  distinct  species,  claiming  that  all  three  forms  are  sym- 
patric  in  the  western  cordillera  of  Guatemala,  and  that  salvini 
and  rufifrons  are  sympatric  in  Vera  Paz.  However,  it  is  sig- 
nificant to  note  that  one  or  another  of  these  forms  has  been 
collected  at  approximately  twenty  localities  in  Guatemala  (vide 
Griscom,  1932,  and  Todd,  1929,  for  lists),  but  at  no  given  place 
has  more  than  a  single  form  been  taken.  Even  when  two  col- 
lectors' stations  are  adjacent,  there  seems  always  to  be  a  dif- 
ference in  their  altitudes.  Thus  sympatry  does  not  appear  to 
exist.  No  intergradation  between  B.  r.  delattrii  and  either  B.  r. 
rufifrons  or  B.  r.  salvini  is  known  but  this  may  be  of  little 
significance  since  even  in  the  comparatively  well-studied  region 
of  Veracruz  integration  between  B.  r.  rufifrons  and  B.  r.  scdvini 
was  undetected  until  1943  (Wetmore).

Icterus  mesomelas  mesomelas  (Wagler) 

Id,  July  27;  1  9  ,  Aug.  12. 

The  male  weighed  42.7  grams;  the  female  35.0  grams.  Orni- 
thoctona  fusciventris  was  found  on  the  latter. 

The  dearth  of  clearings  meant  that  habitats  for  most  of  the 
Icteridae  were  lacking.  The  almost  total  absence  of  orioles  was 
one  of  the  impressive  ornithological  features  of  the  Laguna 
Ocotal  region. 

An  oropendola  was  seen  in  the  forest  by  one  of  the  party,  but 
whether  it  was  Zarhynchus  wagleri  or  Gymnostinops  montezuma 
is  unknown.

One  bird  was  taken  in  the  pines  and  the  others  in  the  low 
forest.    The  species  was  rather  uncommon. 

The  male  collected  August  2  had  slightly  enlarged  gonads; 
that  taken  August  17  retained  about  half  of  its  juvenal  plumage 
but  had  fully  enlarged  testes.  Breeding  in  transitional  plumage 
has  been  reported  before   (e.g.,  Skutch,  1954). 

The  first  male  weighed  14.8  and  the  second  16.4  grams;  the 
female  17.6  grams.

the  tops  of  the  trees  in  flocks  of  about  ten  individuals. 

A  male  weighed  46.2  grams;  females  40.3,  46.2,  47.4,  and 
48.4  grams. 

PlILOGOTIIRAUPIS   SANGUINOLEXTA    SANGUINOLENTA    (LeSSOn) 
1  6  ,  July  25 ;  1  $ ,  July  2(5 ;  1  $ ,  Aug.  12  ;  1  ?,  Aug.  13. 

The  weights  of  the  males  were  38.8,  40.0,  and  44.2  grams. 

The  species  was  moderately  common  but  more  shy  than  most 
tanagers.  It  came  to  exposed  areas  at  times  but  generally  was 
present  in  the  heavier  selva. 

PlRANGA  LEUCOPTERA  LEUCOPTERA    (Trildeau) 
1  ?,  July  22  ;  1  <J ,  Aug.  4;  1  $ ,  Aug.  3 1 ;  1  9  ?,  Aug.  16;  2  $ ,  Aug.  18. 

Usually  these  birds  were  found  in  small  flocks  along  the  edges 
of  trails  and  in  the  monte. 

The  mean  weight  of  five  males  was  16.68±.32.  They  ranged 
from  15.5  to  17.4  grams. 

One  specimen  harbored  the  bird-fly  Ornithoctona  fusciventris.

BIOLOGICAL  INVESTIGATIONS  IN    CHIAPAS,    MEXICO  277 

This  form  was  more  common  than  H.  gutturalis.  Both  species 
occurred  throughout  the  broadleaf  forest,  with  occasional  ap- 
pearances in  the  monte.  There  was  no  noticeable  difference  in 
habitat  preference  between  the  two  forms. 

These  specimens  lend  credence  to  the  suggestion  (Paynter. 
1955)  that  II.  r.  nelsoni  may  weigh  less  than  H.  r.  rubicoides, 
although  this  still  cannot  be  proved.  Six  adult  male  H.  r.  rubi- 
coides  ranged  from  35.8  to  40.5  grams,  with  a  mean  of  38.00±.71 ; 
five  adult  females  from  27.8  to  33.6  grams,  with  a  mean  of 
31.04±1.07.  Adult  males  of  typical  H.  r.  nelsoni  were  reported 
i  Paynter,  1955)  to  weigh  27.7,  30.4,  31.5,  and  32.1  grams;  a 
female  27.5  grams. 

Habia  gutturalis  salvini  (Berlepsch) 

1   .',  July  23  ;  1$,  July  24 ;  1$,  July  27 ;  1$,  July  30. 

The  unsexed  specimen  weighed  42.9  grams;  the  remaining 
birds  all  of  which  are  immature,  42.7,  43.6,  and  43.7  grams. 

This  series  is  unsatisfactory  for  subspecific  determination.  It 
seems,  however,  to  be  more  similar  to  immature  specimens  from 
the  range  of  H.  g.  salvini  than  to  the  limited  material  I  have 
seen  of  immature  H.  g.  litioralis,  a  weak  or  possibly  invalid,  race. 

Chlorospingus  ophthalmicus  dwighti  Underdown

1$,  July  24;  IS,  Aug.  1;  1$,  Aug.  2;  1?,  Aug.  7;  1  ?,  Aug.  10. 
Along  the  edges  of  trails  and  within  the  broadleaf  forest, 
wherever  there  was  low  vegetation,  these  birds  swarmed. 

Adult  males  weighed  18.6,  18.7,  and  19.7  grams;  females  17.2 
and  17.4  grams.  Juvenal  males  weighed  18.6,  18.6,  18.7,  and 
18.8  grams;  females  16.0  and  17.3  grams. 

Chlorophanes  spiza  guatemalensis  Sclater

The  species  was  most  often  seen  in  the  Clusia  tree  at  the  camp. 


278  BULLETIN  :  MUSEUM  OF  COMPARATIVE  ZOOLOGY 

Adult  males  weighed  13.1  and  13.3  grams;  an  immature  male 
12.2  grams;  females  12.3  and  13.4  grams. 

Saltator  atriceps  atriceps  (Lesson) 

1  <S  ,  Aug.  9  ;  1  9  ,  Aug.  10. 

The  gonads  of  the  male  were  very  enlarged  and  that  of  the 
female  moderately  enlarged. 

None  of  the  saltators  was  common,  but  this  was  the  most 
frequently  observed  of  the  three.  All  the  forms  frequented  the 
brush  where  the  broadleaf  and  pine  forests  joined. 

The  weights  of  the  male  and  female  were  77.3  and  85.5  grams, 
respectively. 

Saltator  maximus  gigantoides  Cabanis 

1  9  ,  Aug.  3 ;  1  $ ,  Aug.  12. 

These  specimens  have  only  a  trace  of  green  on  the  pelium, 
leaving  no  doubt  that  they  are  referable  to  this  race  rather  than 
to  S.  m.  magnoides,  which  has  been  recorded  from  near  Comitan 
(Berlioz,  1939). 

The  male,  which  had  enlarged  testes,  weighed  52.3  grams. 
The  female,  whose  ovary  was  slightly  enlarged,  weighed  48.4 
grams. 

Saltator  coerulescens  yucatenensis  Berlepsch 

1  6  ,  July  27. 

To  find  this  race  at  Laguna  Ocotal  was  unexpected,  but  the 
specimen  is  pale,  has  only  a  faint  wash  of  buffy  on  the  breast, 
and  has  a  light  crissum,  all  characters  differentiating  S.  c. 
yucatenensis  from  8.  c.  grandis.  Although  it  may  be  an  aber- 
rant bird,  additional  specimens  from  the  region  will  probably 
confirm  the  identification,  inasmuch  as  Brodkorb  (1943)  found 
a  series  from  eastern  Tabasco  to  be  closer  to  S.  c.  yucatenensis 
than  to  8.  c.  grandis. 

The  bird,  which  was  reproduetively  active,  weighed  54.2  grams. 

Caryothraustes  poliogaster  poliogaster   (Du  Bus) 

1$,  19,  Aug.  10;  19,  Aug.  18. 
Flocks  of  these  birds  were  seen  regularly  in  one  area  of  transi-

tion  between  the  selva  and  ocotal,  where  the  vegetation  was 
fairly  high  but  not  dense.   They  were  seldom  seen  elsewhere. 
The  male  weighed  48.6  grams ;  the  females  49.3  and  50.7  grams. 

Cyanocompsa  cyanoides  concreta    (Du  Bus) 

1  $  ,  July  27 ;  1  $  ,  July  31 ;  1$,  Aug.  14;  1$,  Aug.  19. 

The  male  taken  July  27  had  enlarged  testes.  That  collected 
on  August  14,  an  immature  bird,  was  host  to  Ornithoctona 
fusciventris. 

Adult  males  weighed  30.5  and  30.9  grams;  an  immature 
male  27.6  grams;  an  adult  female  30.4  grams. 

Sporophila  torqueola  morelleti   (Bonaparte) 

1  $  ,  July  26 ;  1  $ ,  Aug.  8 ;  1  $  ,  Aug.  13. 

Iii  the  vicinity  of  the  marsh  near  the  campsite,  seedeaters 
were  seen  and  heard  daily.  A  few  were  also  found  in  the  pine 
burn,  but  none  elsewhere. 

The  bird  taken  on  August  13,  which  is  immature,  weighed 
8.7  grams.  The  remaining  birds  were  in  full  breeding  condition 
and  weighed  8.9  and  9.6  grams. 

Oryzoborus  funereus  Sclater 

13,19,  Aug.  2. 

The  birds,  both  of  which  had  fully  enlarged  gonads,  were 
collected  in  the  pine  burn.  The  area  was  searched  for  additional 
birds,  but  this  pair  was  the  only  one  found.  The  species  was 
reported  from  Chiapas  once  before   (Brodkorb,  1943). 

The  weights  of  the  male  and  female  were  14.3  and  14.7  grams, 
respectively. 

Atlapetes  albinucha  (Lafresnaye  and  d'Orbigny) 

1$,  July  30;  1  $  ,  Aug.  3. 

The  August  3  specimen  is  a  fledgling,  which  was  barely  able 
to  fly ;  the  other  a  juvenal.  Both  birds  were  taken  in  the  under- 
brush of  the  pine  burn.  Only  one  other  was  seen  during  the 
month  at  the  site. 

The  fledgling  weighed  32.5  and  the  juvenal  33.2  grams.

DISCUSSION 

One  hundred  and  twenty-two  species  of  birds  were  collected 
or  observed  during  the  period  spent  at  Laguna  Ocotal.  Of  this 
number,  11!)  are  presumed  to  breed  in  the  vicinity  and  three  are 
known  to  be  visitors  (Empidonax  minimus,  Mniotilta  varia,  and 
Seiurus  motacilla). 

The  avifauna  of  the  lowlands  to  the  north  and  to  the  east 
of  the  Selva  Lacandona  is  fairly  well  known,  affording  a  useful 
basis  for  comparison  with  that  which  was  found  at  Laguna 
Ocotal.  Brodkorb  (1943)  has  surveyed  the  birds  of  Tabasco  and 
adjacent  areas  in  Veracruz,  Campeche,  and  Chiapas;  Tashian's 
report  (1952)  on  the  birds  of  Palenque,  Chiapas,  is  an  informa- 
tive supplement.  To  the  east,  the  district  of  Peten,  Guatemala, 
has  been  investigated  by  Van  Tyne  (1935)  and  Taibel  (1955). 
The  localities  encompassed  by  these  papers  are  situated  at  alti- 
tudes below  250  meters,  with  a  few  insignificant  exceptions.  A 
large  part  of  the  region  is  covered  by  "high  evergreen  forest," 
to  use  the  terminology  of  Miranda  (1952).  However,  the  com- 
position of  the  forest  differs  from  that  at  Laguna  Ocotal  and 
is  the  type  commonly  called  "rain  forest."  The  distinction 
between  the  high  evergreen  forest  at  Laguna  Ocotal  and  that 
which  is  found  at  lower  altitudes  is  considered  in  the  paper  in- 
troducing this  series  pp.  193-199). 

The  birds  in  the  highlands  contiguous  with  the  Selva  Lacan- 
dona are  not  so  well  known.  Berlioz's  (1939)  report  on  a  collec- 
tion from  the  district  of  Comitan  is  the  nearest  approach  to  a 
detailed  study,  but  it  seems  that  the  collector  (Mario  del  Toro 
Aviles)  was  selective  and  did  not  attempt  to  obtain  repre- 
sentatives of  all  the  species  in  the  region.  The  paucity  of  rap- 
torial and  aquatic  species  is  particularly  noticeable.  The  col- 
lector spent  a  few  days,  in  April  and  October,  at  Comitan  (alt. 
1650  m.),  a  sizable  town  on  a  plain,  with  oak  and  coniferous 
forests  a  short  distance  away.  He  collected  for  20  days  in  August 
and  for  four  days  in  October  at  Juncana  (alt.  1(345  m.),  a  village 
situated  in  the  oaks  and  pines,  40  kilometers  southeast  of  Comi- 
tan. From  May  to  August  he  worked  at  Santa  Rosa,  which, 
Prof.  Brodkorb  {in  litt.)  informs  me,  is  a  finca,  at  an  altitude 
of  about  1200  meters,  near  the  Guatemala  border  and  east  of 
Laguna    Montebello,    roughly   seventy   kilometers    southeast    of 


BIOLOGICAL  INVESTIGATIONS    IX    CHIAPAS,    MEXICO  281 

Coniitan.  According  to  Prof.  Brodkorb,  this  region  is  character- 
ized by  high  rainfall  and  by  the  presence  of  the  Sweet  Gum 
(Liquidambar  styraciflua).  Miranda  (1952)  maps  the  area 
within  the  zone  of  "temperate  deciduous  woods,"  one  of  whose 
key  species  is  Liquidambar. 

When  the  resident  birds  at  Laguna  Ocotal  are  compared  with 
those  known  from  adjacent  Veracruz,  Tabasco,  Chiapas,  Cam- 
peche,  and  Peten  (Brodkorb,  1943;  Tashian,  1952;  Van  Tyne, 
1935;  Taibel,  1955),  it  is  seen  (Table  1,  p.  284)  that  24  of  the  119 
species  (22  per  cent)  have  not  been  found  in  the  lowlands  en- 
compassed by  these  studies.  Of  these  24  birds,  four  (Spizaetus 
tyr annus,  Micrastur  semitorquatus,  31.  ruficollis,  and  Chloro- 
phanes  spiza)  are  uncommon  species  which  have  been  collected 
at  low  altitudes  nearby,  e.g.,  on  the  Yucatan  Peninsula  (Payn- 
ter,  1955),  and  in  time  probably  will  be  found  in  the  regions 
under  consideration.  The  20  species  remaining  are  characteristic 
of  higher  elevations,  with  none  having  been  found  below  roughly 
300  meters,  at  least  in  northern  Middle  America. 

With  the  exception  of  the  pines,  the  vegetation  at  Laguna 
Ocotal  is  pbysiognomically  similar  to  that  of  the  lowlands. 
Therefore,  the  presence  of  the  conifers  might  logically  seem 
to  be  the  cause  of  the  difference  in  composition  of  the  two 
avifaunas.  However,  this  is  not  the  case.  Only  four  species 
are  confined  to  the  pines  at  Laguna  Ocotal.  These  are  Lepidoco- 
laptes  souleyetii,  L.  affinis,  Contopus  pertinax,  and  Basileuterus 
rufifrons;  Dendroica  graciae  was  abundant  in  the  pines  but  was 
seen  in  the  broadleaf  forest  on  a  few  occasions.  Of  these  five 
species,  only  Lepidocolaptes  affinis  and  Dendroica  graciae  do  not 
occur  in  the  adjacent  lowlands.  More  subtle  differences  in  the 
environments  must  be  responsible  for  the  discrepancy  between 
the  avifaunas  of  the  two  regions. 

If  the  resident  birds  of  Laguna  Ocotal  are  compared  with  those 
listed  by  Berlioz  (1939)  for  the  District  of  Comitan,  Chiapas 
(2100  to  1650  m.),  it  is  seen  (Table  2,  p.  285)  that  54  species  (45 
per  cent)  have  not  been  recorded  at  the  higher  elevations.  Owing 
to  what  certainly  was  discriminating  collecting  in  the  highlands 
(e.g.,  Cathartes  aura  is  not  recorded),  the  difference  between 
the  two  avifaunas  is  doubtless  exaggerated,  but  still  it  must  be 
substantial.  Most  of  the  species  in  Table  2  are  forms  which 
frequent  lower  altitudes  and  would  be  unexpected  in  the  District 


282  BULLETIN  :  MUSEUM  OP  COMPARATIVE  ZOOLOGY 

of  Comitan.  It  is  interesting  to  note  that  of  the  24  birds  listed 
in  Table  1  as  not  occurring  in  the  nearby  lowlands,  18  are  re- 
corded in  the  highlands  (Berlioz,  1939),  including  the  so-called 
"lowland  forms"  Micrastur  ruficollis  and  Chlorophanes  spiza. 

From  this  it  may  be  concluded  that  the  composition  of  the 
avifauna  of  Laguna  Ocotal  is  intermediate  between  that  of  the 
adjacent  lowlands  and  highlands,  with  a  stronger  element  from 
the  lowlands.  The  presence  of  pines  at  Laguna  Ocotal,  the  one 
strikingly  marked  vegetational  difference  between  the  lowlands 
and  the  lake  district,  has  almost  no  effect  on  the  composition  of 
the  avifauna.

DESIGN  QUANTITIES  OF  SOME  CHIAPAS  BIRDS 

By 

Charles  H.  Blake 

What  an  airplane  or  a  bird  is  capable  of  in  the  way  of  flight 
is  largely  deducible  from  a  few  rather  simple  ratios.  Obviously, 
ability  to  perform  as  well  as  the  design  permits  depends  on  an 
adequate  power  plant  and  a  sufficiently  strong  and  responsive 
control  system.  We  do  not  yet  know  how  to  assess  these  latter 
properties  in  a  bird,  but  the  design  quality  of  the  wings  can  be 
discussed  in  general  from  the  quantities  here  presented. 

Three  quantities  are  considered  here :  wing  loading,  span  load- 
ing, and  aspect  ratio.  These  are  derived  from  three  measure- 
ments :  weight,  wing  area,  and  wing  span.  English  units  are  used 
to  render  comparison  with  airplanes  easier. 

The  area  is  that  of  the  slightly  flattened  wings.  Ideally  it 
should  be  the  projected  area  of  the  wings  fully  outstretched  in 
flight.   This  can  only  be  closely  approximated. 

The  span  is  twice  the  length  of  the  wing  beyond  the  edge  of 
the  body  in  the  attitude  in  which  the  area  is  measured.  This  is 
less  than  the  tip  to  tip  distance  or  wing  expanse. 

Wing  loading  is  expressed  as  pounds  of  weight  per  square  foot 
of  wing  area.  Similarly  span  loading  is  in  pounds  per  foot  of 
span. 

The  aspect  ratio  is  dimensionless  and  most  conveniently  cal- 
culated as  the  square  of  the  span  divided  by  the  wing  area. 

The  wing  loading  is  an  indicator  of  the  relative  power  required 
for  acceleration.  Takeoff  and  climbing  are  more  difficult  with 
higher  wing  loading.  On  the  other  hand,  stability  varies  in  the 
same  sense  as  wing  loading.  Span  loading  is  a  measure  of 
maneuverability.  Birds  with  high  span  loadings  will  have  diffi- 
culty in  turning  rapidly  unless  the  aspect  ratio  is  very  low.  The 
aspect  ratio  is  related  to  lift.  The  higher  the  aspect  ratio  the 
greater  the  lift  in  proportion  to  the  wing  area.  In  general,  birds 
with  high  aspect  ratios  glide  and  soar  readily  or  remain  in  the 
air  for  long  periods  or  both.  It  is  also  generally  true  that  a  high 
aspect   ratio   improves  stability  at  low  speeds.    Similar  effects 


BIOLOGICAL   INVESTIGATIONS  IN   CHIAPAS,    MEXICO  287 

can  be  obtained  by  high  wing  camber  or  an  appropriate  dihedral 
angle  between  the  wings. 

I  am  greatly  indebted  to  Raymond  A.  Paynter,  Jr.  for  making 
(in  the  field)  the  outlines  of  the  wings  of  21  birds  comprising  18 
species,  shown  in  the  table,  and  recording  the  weights  of  the 
individuals  drawn.  The  series  is  important  because  it  gives  us 
our  first  information  on  almost  all  the  included  families,  and 
it  is  the  first  sizable  series  of  sedentary  species.  I  also  thank 
the  Geological  Survey  Department,  Jamaica,  B.  W.  I.,  for  the 
use  of  a  planimeter. 

There  is,  of  course,  great  risk  in  speaking  definitely  about  the 
flight  of  species  one  has  never  seen  alive.  Some  general  remarks 
may  be  made  on  the  basis  of  the  quantities  themselves.  The  wing 
loadings  are  very  diverse.  Tinamus  has  a  loading  that  is  high 
even  for  a  bird  weighing  nearly  2y2  pounds.  By  contrast,  the 
specimen  of  Ortalis  has  less  than  one-third  the  weight  but  more 
than  two-thirds  the  wing  area  of  the  Tinamus.  One  would  readily 
believe  that  Tinamus  would  take  off  with  difficulty  and  even  re- 
luctantly. It  might,  however,  fly  well  on  a  straightaway  after  it 
was  up  to  speed.  This  is  a  matter  of  motor  rather  than  wings. 
If  the  motor  is  only  sufficiently  powerful  to  maintain  cruising 
speed,  then  takeoff  becomes  virtually  impossible.  This  is  probably 
not  quite  true  of  any  bird.  With  a  high  wing  loading  consid- 
erable excess  power  must  be  available.  These  remarks  also 
apply,  with  less  force,  to  the  toucan,  Pteroglossus,  and  the  parrot, 
Pionus.  If  the  figures  for  other  parrots  are  similar  to  those  for 
Pionus,  their  rather  labored,  although  rapid,  flight  is  under- 
standable. At  the  other  extreme  are  a  hummingbird,  Abeillia, 
and  a  woodhewer,  Sittasomus,  whose  wing  loadings  are  close  to 
the  lowest  on  record.  Their  flight  should  be  about  equally  un- 
stable but  in  other  respects  entirely  different. 

Turning  to  the  span  loadings,  Tinamus  is  again  unusual  in  its 
high  loading.  No  other  bird  in  the  list  exceeds  0.5  and  span 
loadings  above  this  latter  figure  are  very  rare.  The  two  hum- 
mingbirds show  the  lowest  loadings.  It  should  be  noted  that 
Eupherusa  has  about  twice  the  wing  loading  as  well  as  about 
twice  the  span  loading  of  Abeillia.  It  would  be  expected,  a 
priori,  that  the  flight  of  these  two  birds  would  be  quite  different. 
Abeillia  ought  to  be  the  more  maneuverable.   It  is  possible  that 


288  BULLETIN  :  MUSEUM  OF  COMPARATIVE  ZOOLOGY 

the  curious  flitting  flight  occasionally  shown  by  some  of  the  larger 
hummingbirds,  notably  Trochilus  and  Anthracothorax,  is  con- 
nected with  the  very  low  loadings  and  high  aspect  ratios. 

The  aspect  ratio  shows  clearly  that  only  the  hummingbirds 
would  be  likely  to  fly  continuously  for  any  length  of  time.  But 
two  other  species  in  the  list  even  attain  a  ratio  of  5.0  and  one 
of  these  is  the  parrot.  These  low  ratios  may  well  be  characteristic 
of  nearly  non-migratory  species.  Generally  the  aspect  ratio  of 
North  American  passerines  seems  to  be  from  5.5  to  7.  I  have 
recently  measured  a  specimen  of  Coccyzus  americanus,  migratory 
but  not  appearing  to  be  a  strong  flyer,  and  found  an  aspect  ratio 
of  5.9. 

In  this  connection  it  is  of  more  than  incidental  interest  that 
one  of  Otto  Lilienthal's  later  gliders  had  an  aspect  ratio  of 
about  Sy2.  Such  a  machine  would  have  very  low  stability  at  low 
speeds  and  his  control  system  was  slow  and  cumbersome.  It 
is  no  wonder  that  he  met  his  death  in  a  crash.  On  the  other 
hand,  a  small  bird  has  such  low  terminal  velocity  that  the  legs 
can  take  up  the  shock  of  a  fall  from  almost  any  height.  The 
bird  gets  into  trouble  by  running  into  some  barrier  beak  first 
in  full  flight  or  attempting  to  land  while  its  forward  speed  is 
much  in  excess  of  stall  speed. 

In  two  cases,  as  shown,  two  individuals  of  the  same  sex  were 
available.  The  derived  ratios  agree  within  10  per  cent;  quite  a 
reasonable  agreement. 

With  a  few  exceptions,  the  general  picture  is  one  of  low  speed, 
short  and  unstable  flight.  It  is  probable  that  most  of  these  birds 
do  not  venture  out  in  the  open  where  they  might  encounter 
both  wind  and  turbulence.

MAMMALS  COLLECTED  AT  LAGUNA  OCOTAL 

By 

Prances  L.  Burnett  and  Charles  P.  Lyman 

This  collection  was  made  at  Laguna  Ocotal,  Chiapas,  Mexico, 
between  July  22  and  August  19,  1954,  by  K.  A.  Paynter,  Jr., 
and  Elisha  P.  Lee.  The  specimens  were  all  collected  in  the 
vicinity  of  the  camp,  and  consist  of  skins  and  skulls,  unless  other- 
wise noted. 

The  mammals  are  for  the  most  part  lowland  forms,  with  a 
few  subspecies  which  are  so  widespread  that  they  are  found  in 
the  highlands  as  well.  In  subspecies  with  restricted  ranges,  the 
races  from  Laguna  Ocotal  are  in  general  similar  to  those  col- 
lected by  Kuns  and  Tashian  (1954)  from  Palenque  to  the 
northwest,  while  Murie's  (1935)  collection  from  Uaxactun, 
Peten,  Guatemala,  to  the  northeast  contains  more  species  endemic 
to  the  Yucatan  Peninsula.  Of  the  mammals  which  tend  to  be 
restricted  to  the  Yucatan  Peninsula,  the  fruit  bat  Artibeus 
jamaicensis  yucatanicus  is  the  only  race  represented  in  the  col- 
lection from  Laguna  Ocotal. 

We  wish  to  thank  Dr.  Charles  0.  Handley,  Jr.,  of  the  United 
States  National  Museum  for  comparing  our  spider  monkey  with 
material  in  the  United  States  National  Museum.  Also  we  grate- 
fully acknowledge  the  loan  of  comparative  material  from  the 
following  institutions:  Museum  of  Zoology,  Ann  Arbor,  Michi- 
gan; American  Museum  of  Natural  History,  New  York  City; 
Pish  and  Wildlife  Service,  United  States  Department  of  the 
Interior,  Washington,  D.C.;  Chicago  Museum  of  Natural  His- 
tory, Chicago,  Illinois;  and  Museum  of  Natural  History,  Law- 
rence, Kansas.  In  particular,  we  thank  Miss  Barbara  Lawrence 
for  her  help  in  preparation  of  the  manuscript. 

Didelphis  marsupialis    ?subsp. 

15,299   (M.C.Z.  47274-47276) 
These  young  opossums  are  relatively  too  large  to  be  yuca- 
tanensis  and   could  be   assigned   to   tabascensis   on  geographic 


BIOLOGICAL     INVESTIGATIONS     IN     CHIAPAS,     MEXICO  291 

grounds.  One  difference  between  the  latter  subspecies  and 
mesamericana  (—marsupialis  Allen,  1901)  was  said  to  be  the 
greater  length  of  tail  compared  to  head  and  body.  Using  Allen's 
tables  it  is  found  that  the  average  of  the  individual  ratios  of  tail 
length  to  head  and  body  length  for  42  mesamericana  is  89.8 
(expressed  in  per  cent)  with  a  standard  deviation  of  ±7.5  while 
the  ratio  for  21  tdbascensis  is  91.9  with  a  standard  deviation  of 
±11.5.  Obviously  this  difference  has  no  statistical  value.  The 
Laguna  Ocotal  specimens  have  ratios  of  tail  length  to  head  and 
body  length  of  84,  88  and  91. 

Long  nasals,  terminating  posteriorly  in  a  sharp  point,  were 
also  used  to  characterize  tdbascensis.  However,  in  four  specimens 
in  the  M.C.Z.  collection,  all  taken  within  a  few  days  in  the 
vicinity  of  Cordoba,  Veracruz,  one  (M.C.Z.  39772)  has  nasals 
which  come  to  a  sharp  point  in  the  midline,  while  the  posterior 
portion  of  the  nasals  of  another  (M.C.Z.  39770)  are  rounded  in 
outline.  The  two  others  (M.C.Z.  39771  and  39767)  have  nasals 
which  are  intermediate  between  the  extremes.  There  is  no  indi- 
cation that  the  shape  of  the  nasals  is  dependent  on  the  age  or 
the  sex  of  the  animals.  As  the  length  of  the  nasals  depends 
partly  on  the  shape  of  their  posterior  border,  measurements  of 
nasal  length  on  skulls  of  the  same  size  would  then  vary  according 
to  the  outline. 

Our  evidence  supports  Hershkovitz's  (1951)  opinion  that  there 
is  only  one  widespread  form  of  Did  el  phis  marsupialis  in  Mexico 
and  in  Central  America  north  of  the  highlands  of  Nicaragua. 

Artibeus  jamaicensis  yucatanicus  J.  A.  Allen 

4$ 6 ,32 9    (M.C.Z.  -47278-47284) 

The  measurements  of  these  fruit  bats  correspond  with  those 
that  Andersen  (1908)  gives  for  yucatanicus  rather  than  those 
for  the  larger  race,  jamaicensis.  Andersen  did  not  group  his 
results  according  to  sex,  but  forearm  length  and  various  skull 
measurements  of  the  Laguna  Ocotal  specimens  indicate  that  the 
females  tend  to  be  smaller  than  the  males.  Our  Chiapas  skulls 
are  smaller  than  jamaicensis  skulls  of  the  same  sex  from  Vera- 
cruz, British  Honduras,  and  Honduras. 

Other  scattered  records  indicate  that  this  subspecies  ranges 
into  northern  Guatemala  (Murie,  1935)  and  northeastern  Chiapas 
(Kuns  and  Tashian,  1954).

Alouatta  palliata  pigra  Lawrence 

■2  6  6,19  (M.C.Z.  4726G-47268)  Skins  and  skeletons 
This  series  of  howler  monkeys  was  all  collected  in  August  from 
a  band  of  five  individuals.  The  skin  of  the  female  is  typically 
black  and  in  this  resembles  a  male  topotype  from  British  Hon- 
duras collected  in  April.  The  males,  on  the  other  hand,  have  an 
extensive  region  between  the  shoulders,  fading  to  a  point  in  the 
middle  of  the  back,  where  the  bases  of  the  hairs  are  pale.  In 
addition,  similarly  colored  hairs  are  interspersed  among  the 
darker  hairs  under  the  forearms  of  one  of  these  skins.  All  have 
longer,  denser  hair  than  has  the  single  topotype.  The  skulls  of 
the  males  are  even  more  massive  than  the  topotype  while  that  of 
the  female  is,  as  would  be  expected,  considerably  smaller. 

The  collection  of  these  specimens  extends  the  range  of  pigra 
125  miles  to  the  west  and  south  of  the  type  locality  of  Uaxactun, 
Guatemala.  Kuns  and  Tashian  (1954)  report  a  specimen  from 
Palenque,  Chiapas  as  mexicana. 

Ateles  geoffroyi  vellerosus  Gray 

1  9   (M.C.Z.  47269)  Skin  and  skeleton 

Dr.  Charles  0.  Handley,  Jr.  very  kindly  identified  this  speci- 
men of  spider  monkey  as  vellerosus  through  comparison  with 
material  in  the  United  States  National  Museum.  He  writes  that 
the  Laguna  Ocotal  skin  is  very  similar  to  one  from  Palenque 
in  Chiapas,  but  somewhat  darker  and  more  richly  colored  than 
specimens  from  Oaxaca  and  Veracruz.  No  comparison  was 
needed  with  pan  from  Guatemala,  which  is  very  much  blacker, 
nor  yucatanensis  which  is  smaller  and  paler.  This  specimen  was 
collected  well  within  the  range  of  this  widespread  subspecies 
(Kellogg  and  Goldman,  1944). 

Paynter  reports  that  there  were  fewer  spider  monkeys  than 
howler  monkeys  at  the  lake.  Small  bands  of  three  or  four  Ateles 
were  seen  every  few  days,  while  bands  of  howler  monkeys  could 
be  heard  around  the  camp  almost  every  evening.

central  Veracruz  but  are  a  little  smaller  when  compared  to  the 
measurements  given  by  Nelson  (1899).  Apparently  the  north-

north  west  through  Laguna  Ocotal  to  Palenque  (Kuns  and  Tash- 
ian,  1954).  To  the  northeast  Murie  (1935)  found  the  brighter 
colored  vivax.  At  Laguna  Ocotal  the  habitat  of  this  squirrel  was 
restricted  to  the  tropical  evergreen  forest. 

SCIUBUS  AUREOGASTER  AUREOGASTER  F.   Clivier 

16,299   (M.C.Z.  47286-47288) 

The  collection  of  fire-bellied  squirrels  at  Laguna  Ocotal  extends 
the  limits  of  their  range  more  to  the  south  and  closer  to  the 
Guatemalan  border,  though  Dr.  Remington  Kellogg  and  Dr. 
Charles  0.  Handley,  Jr.  write  us  that  no  specimen  of  aureogaster 
has  yet  been  taken  in  Guatemala  proper.  In  comparison  with 
more  northern  specimens  no  noticeable  differences  in  the  skulls 
could  be  found,  but  these  Chiapas  squirrels  are  not  as  dark  in 
color.  However,  as  Kelson  (1952)  has  pointed  out,  aureogaster 
varies  considerably  in  the  degree  of  melanism  in  various  areas 
of  its  range. 

Paynter  found  these  squirrels  on  the  forest  edges,  amid  thick 
tangles  of  small  trees  and  vines,  in  contrast  to  the  deep  forest 
habitat  of  deppei.

Fifty-one  skins  and  skulls,  as  well  as  three  skulls  only,  were 
collected  of  this  larger  rice  rat.  Most  of  these  animals  were  quite 
young,  ranging  from  sub-adults  with  the  upper  third  molars 
just  erupting  to  adults  with  slightly  worn  molars.  The  pelage 
of  these  animals  is  darker  than  that  of  specimens  from  Yaruca,

Honduras,  which  Goldman  (1918)  considered  typical  couesi.  This 
darker  cast  is  due  to  a  more  plumbeous  color  in  the  bases  of  the 
dorsal  hairs,  with  the  guard  hairs  being  black  instead  of  brown- 
ish. A  detailed  comparison  of  the  skulls  of  these  specimens  with 
over  90  couesi  of  similar  ages  (as  indicated  by  tooth  wear)  from 
other  localities  revealed  no  significant  differences  in  the  Laguna 
Ocotal  specimens.  Topotypical  adults  of  pinicola  from  Pine 
Ridge,  British  Honduras,  were  smaller  than  mature  but  younger 
animals  from  Laguna  Ocotal. 

0.  c.  couesi  appears  to  be  a  very  widespread  subspecies,  and, 
except  for  the  somewhat  darker  color,  our  specimens  are  typical 
of  the  race. 

Oryzomys  alfaroi  palatinus  Merriam 

9  6  $,  7  9  9  (M.C.Z.  47303-47305,  47319-47330,  47355) 
Although  some  of  these  smaller  rice  rats  have  a  dorsal  pelage 
dark  enough  to  fit  the  description  of  saturatior,  others  are  almost 
as  pale  as  Panamanian  specimens  of  alfaroi,  which  palatinus  re- 
sembles in  coloration.  All  of  the  Laguna  Ocotal  animals  have 
whitish  underparts,  rather  than  the  buffy  ones  ascribed  to  satura- 
tior, and  are  hence  referred  to  palatinus.  As  Goldman  points  out 
(1918),  palatinus  and  saturatior  inhabit  the  same  mountain 
range,  and  intergradation  between  the  two  races  is  probable. 

Ototylomys  phyllotis  guatemalae  Thomas 

:'>i  S    (M.C.Z.  47301,  47302,  47386) 

Two  skins  and  skulls,  and  an  additional  single  skull,  were 
taken  of  this  smaller  genus  of  tree  climbing  rats.  The  diagnostic 
characters  given  by  early  authors  (Merriam,  1901,  Thomas,  1909, 
and  Sanborn,  1935)  do  not  hold  when  applied  to  the  present 
specimens  and  the  descriptions  by  Laurie  (1953)  were  not 
sufficiently  definitive  to  clarify  the  situation.  Furthermore,  the 
published  records  of  the  distribution  of  this  group  are  confused. 

Although  these  animals  are  generally  rare  in  collections,  it 
was  possible  to  borrow  seventy  specimens,  including  one  series 
from  Esmeralda,  Quintana  Poo,  Mexico,  and  another  from  Uax- 
actun,  Peten,  Guatemala.  Examination  of  these  specimens 
showed  that  Ototylomys  could  be  divided  into  two  groups.    One 


BIOLOGICAL    INVESTIGATIONS    IN    CHIAPAS,    MEXICO  295 

group  consists  of  a  smaller  animal  with  an  upper  molar  tooth 
row  measuring  5.9  to  6.5  mm.,  from  the  Yucatan  Peninsula  south 
to  Peten,  and  the  other  group  consists  of  a  larger  animal  with 
an  upper  tooth  row  of  6.9  to  7.5  mm.,  from  Chiapas  and  Alta 
Vera  Paz.  Our  specimens  belong  to  the  group  of  larger  mammals 
which  also  include  connectens  and  guatemalae.  Sanborn  states 
that  connectens  is  the  only  race  in  which  the  belly  hairs  have 
slaty  bases.  However,  in  eight  specimens  within  the  stated  range 
of  connectens  the  bases  of  the  hair  of  the  belly  vary  from  slaty 
gray  (Finca  Chama  and  Chimoxan,  Guatemala)  to  almost  pure 
white  (Concepcion).  Furthermore,  two  specimens  of  guatemalae 
from  Palenque,  Chiapas,  show  a  slaty  cast  of  the  belly  fur, 
particularly  in  the  midline. 

Our  specimens  from  Laguna  Ocotal  also  have  slaty  based  fur  on 
the  belly,  otherwise  they  are  closest  to  Thomas'  description  of 
guatemalae.  They  are  too  small  to  be  referred  to  Sanborn's 
connectens  and  hence  are  considered  to  be  the  former  race.  It 
seems  apparent,  however,  that  Ototylomys  shows  considerable 
variation  within  a  relatively  small  geographic  area,  and  it  is 
suspected  that  some  of  the  characters  which  have  been  used  to 
separate  races  will  be  found  not  to  hold  when  more  specimens 
are  available  for  comparison. 

Peromyscus  mexicanus  teapensis  Osgood 

8  $  $  ,  3  9  5  (M.C.Z.  47308-47318) 
According  to  Osgood  (1909)  the  various  races  of  mexicanus 
are  only  slightly  differentiated.  The  Laguna  Ocotal  specimens 
are  referred  to  teapensis  on  the  basis  of  color  as  well  as  on 
geographic  grounds.  Although  the  pelage  is  very  much  darker, 
the  skulls  closely  resemble  a  series  of  mexicanus  from  Veracruz, 
in  that  they  lack  the  broader  nasals,  heavier  rostrum,  and  more 
massive  molars  ascribed  to  teapensis.  Kims  and  Tashian  (1954), 
while  identifying  their  specimens  from  Palenque  as  teapensis, 
also  noted  that  the  skulls  showed  no  evidence  of  the  thickened 
rostrum.

Sigmodon  hispidus  saturatus  V.  Bailey

One  adult  cotton  rat  and  one  subadult  were  collected.  Both 
animals  are  very  similar  to  specimens  in  the  M.C.Z.  collection 
from  British  Honduras,  except  that  the  tips  of  the  belly  hairs  of 
the  adult  are  generally  more  whitish  than  yellowish.  Laguna 
Ocotal  lies  well  within  the  range  of  this  widespread  subspecies. 

Nasua  narica  narica  (Linnaeus)

resembles  very  closely   older   specimens   of   narica   in   color   of

Odocoileus  virginianus  subsp. 

Robert  Dressier  found  fragments  of  two  tibiae,  two  femora,  one 
scapula  and  one  vertebra  (M.C.Z.  47476-47481)  of  white-tailed 
deer  in  an  Indian  rock  shelter  near  the  camp  at  Laguna  Ocotal. 
Paynter  found  no  evidence  that  this  deer  occurs  naturally  in 
the  area,  and  it  appears  probable  that  the  remains  may  have  been 
carried  there  by  travelling  Indians.  Associated  with  the  bones 
were  shells  of  varieties  of  snails  found  in  the  nearb}^  lake  and 
more  distant  streams. 

Mazama  sp. 

Bones  of  these  small  deer  were  also  found  in  the  rock  shelter 
by  Dressier,  along  with  those  of  the  larger  white-tail.  Mazama 
fragments  consisted  of  a  ramus,  a  scapula,  and  a  vertebra  (M.C.Z." 
47482-47484). 

Brocket  deer  were  seen  by  Paynter  several  times  in  the  "burn 
near  the   camp   at   Laguna   Ocotal.    One   particular   spot  was 
noted  where  single  animals  were  found  bedded  down  on  a  num- 
ber of  occasions. 

Dasypus  novemcinctus  subsp. 

The  shell  of  one  animal  was  found  near  camp,  and  one  live 
armadillo  was  seen  in  the  area.

No.  5  —  The  Genus  Tetragnatha  (Araneae,  Argiopidae)  in 

Panama 

By  Arthur  M.  Checkering 

Albion  College,  Albion,  Michigan 

As  a  result  of  several  visits  to  the  Canal  Zone  and  the  Republic 
of  Panama  for  the  purpose  of  collecting  and  studying  spiders  I 
have  accumulated  a  rather  large  number  of  specimens  belonging 
to  the  interesting  genus  Tetragnatha  Latreille,  1804.  The  present 
study  of  the  genus  is  specifically  concerned  with  its  occurrence 
in  Panama  where  it  appears  to  have  found  exceptionally  favor- 
able conditions. 

Araneologists  who  have  interested  themselves  in  the  genus 
Tetragnatha  have  emphasized  such  characters  as  the  following: 
size  of  the  body ;  shape  of  the  abdomen ;  relative  position  of  the 
eyes ;  several  features  of  the  chelicerae  and  cheliceral  teeth ;  color ; 
relative  lengths  of  the  different  segments  of  the  male  palp  ;  specific 
characteristics  of  the  male  palpal  tarsus;  presence  or  absence  of 
spines  on  legs  and  their  length.  F.  P.  Cambridge  (1903)  paid 
close  attention  to  the  characters  and  relationships  of  the  con- 
ductor and  embolus  in  male  palps.  Petrunkevitch  (1930)  also 
did  this  and,  in  addition,  gave  careful  attention  to  the  appear- 
ance of  the  genital  fold  in  females  which  are  often  difficult  to 
place  with  certainty  because  of  the  absence  of  an  epigynum  and 
other  marked  characteristics.  My  experience  with  the  genus 
seems  to  show  that  close  attention  must  ahvays  be  given  to  the 
specific  shape  of  the  conductor  and  embolus  as  well  as  to  their 
relationships.  These  features  appear  to  be  the  least  variable 
among  all  of  those  used  by  taxonomists  and,  therefore,  the  most 
reliable  for  purposes  of  accurate  determination.  In  females  the 
characters  of  the  genital  fold  are  often  very  helpful.  Size ;  color ; 
number,  relative  size,  and  placement  of  the  cheliceral  teeth  are 
all  subject  to  a  rather  wide  range  of  variation.  These  facts  seem 
to  explain  the  numerous  errors  in  identification  which  can  be 
found  in  almost  every  collection.  In  making. this  study  I  have 
tried  to  take  into  consideration  all  of  these  items  in  making  my 
identifications  and  in  drawing  conclusions  regarding  synonymy.

periods  of  collecting  and  study  of  spiders  in  various  parts  of 
Panama  during  the  past  thirty  years. 

Genus  TETRAGXATHA  Latrcille,  1804 

The  Cambridges  (1889-1903)  reported  the  following  species  of 
this  genus  in  Panama:  T.  alba  F.  P.  Cambridge;  T.  pallida  0.  P. 
Cambridge;  T.  tenuis  0.  P.  Cambridge;  T.  tenuissima  0.  P. 
Cambridge.  Petrunkevitch  (1925)  added  T.  antillana  Simon  to 
the  known  list  from  Panama,  and  Banks  (1929)  recorded  T. 
mexicana  Keyserling.  Chamberlin  and  Ivie  (1936)  described 
four  new  species  from  my  first  collection  of  Panamanian  spiders 
made  in  1928. 

T.  alba  F.  P.  Cambridge  has  proven  to  be  a  synonym  for  T. 
laboriosa  Hentz.  T.  amplidens  Chamberlin  and  Ivie  and  T.  siduo 
Chamberlin  and  Ivie  are  synonyms  for  T.  tropica  0.  P.  Cam- 
bridge. The  male  of  T.  apheles  Chamberlin  and  Ivie  belongs 
with  T.  mexicana  Keyserling  but  the  female  is  a  T.  antillana 
Simon.  T.  ethodon  Chamberlin  and  Ivie  appears  to  be  a  valid 
species.  To  the  best  of  my  knowledge,  therefore,  the  total  list 
of  known  species  of  Tetragnatha  from  Panama  prior  to  this 
study  may  be  stated  as  follows:  T.  antillana  Simon;  T.  ethodon 
Chamberlin  and  Ivie;  T.  laboriosa  Hentz;  T.  mexicana  Keyserl- 
ing; T.  pallida  0.  P.  Cambridge;  T.  tenuis  0.  P.  Cambridge; 
T.   tenuissima  0.   P.  Cambridge;   T.  tropica  0.  P.  Cambridge. 


<  HICKERING:  TETRAGNATHA  IN  PANAMA  303 

As  a  result  of  my  studies  on  this  genus  I  have  definitely  recorded 
the  following  additional  known  species  to  the  list :  T.  caudata 
Emerton;  T.  cognata  0.  P.  Cambridge;  T.  confraterna  Banks; 
T.  guatemalensis  O.  P.  Cambridge;  T.  pallescens  F.  P.  Cam- 
bridge; T.  vermiformis  Emerton.  In  addition  to  these  I  have 
been  compelled  to  recognize  and  describe  T.  fragilis  sp.  nov. ; 
T.  gertschi  sp.  nov. ;  T.  mdbelae  sp.  nov. ;  T.  sinuosa  sp.  nov. 
Thus  the  total  number  of  species  of  Tetragnatha  now  known  to 
occur  in  Panama  amounts  to  eighteen. 

No  attempt  is  made  in  this  paper  to  give  complete  bibliographic 
references.  Only  those  which  are  regarded  as  particularly  per- 
tinent are  included.  Those  who  desire  more  extensive  bibliog-

i The  term  "large  tooth"  is  being  used  in  the  sense  in  which  F.  P.  Cambridge 
employed  it.  In  certain  species  there  is  an  enlarged  proraarginal  tooth  at  about 
thi-  "apical  third  or  fourth."

Females 

Because   of   the   lack  of   distinctive   features  in  females  it  is  difficult   to 
provide    readily   workable   keys.     It    is   hoped,   however,   that   the   following 
key  will  aid  the  student  of  the  group  in  separating  the  females  of  the  dif- 
ferent species.

T.  antillana  Simon  is  well  known  throughout  Mexico,  Central 
America,  most  of  South  America,  and  the  West  Indies.  The  vial 
in  the  collection  of  the  Museum  of  Comparative  Zoology  labelled 
the  type  of  T.  eremita  Chamberlin  now  contains  only  a  single 
male  palp  but  this  is  very  definitely  from  T.  antillana  Simon.

clearty  belongs  here.   Moreover,  the  female  of  T.  apheles  Cham- 
berlin  and  I  vie  is  quite  clearly  a  T.  antillana  Simon. 

Male :  Lateral  eyes  somewhat  closer  to  one  another  than  AME 
are  to  PME ;  legs  well  supplied  with  short  spines ;  palpal  patella

embolus  as  shown  in  Figure  2;  the  paracymbiuni  is  distally 
bifurcate  (Fig.  3)  ;  the  fang  is  moderately  sinuous  and  is  without 
a  basal  dorsal  cusp  but  there  is  a  suppressed  tubercle  on  the 
inner  margin  opposite  the  third  promarginal  tooth ;  there  is  no 
"large  tooth"  on  the  promargin  but  the  spur  together  with  the 
two  contiguous  teeth  forms  a  conspicuous  group  of  three  (Fig.  4). 

Female :  The  genital  fold  is  as  shown  in  Figure  5 ;  the  retro- 
margin  of  the  fang  groove  has  a  large  distinctive  tooth  directed 
forward  with  a  small  tooth  near  it  (Fig.  6)  ;  the  promargin  has 
a  similar  pair  of  distal  but  smaller  teeth ;  the  fang  is  moderately 
sinuous  and  there  may  be  a  suppressed  dorsolateral  cusp  near 
its  base ;  the  abdomen  is  not  extended  posterior  to  the  spinnerets 
in  either  sex. 

Collection  records :  The  male  and  female  hypotypes  are  from 
Boquete,  R.  P.,  August,  1950  and  July,  1939,  respectively. 
Numerous  examples  of  both  sexes  from  Boquete,  R.  P.,  July, 
1939,  August,  19,50;  El  Valle,  R.  P.,  July,  1936;  El  Volcan, 
R.  P.,  February- April,  1936  (W.  J.  Gertsch)  ;  one  female  from 
Madden  Dam  Forest,  C.  Z.,  July,  1950.

For  some  time  this  species  was  considered  as  new  and  was 
scheduled  to  be  described  as  such.  After  careful  comparison  with 
T.  caudata  from  the  northern  regions  the  close  similarities  seemed 
to  warrant  regarding  it  as  a  southern  variant  of  this  species. 
Further  knowledge  regarding  it  may  compel  araneologists  to 
regard  it  as  a  separate  species.  T.  caudata  Emerton  has  been 
recorded  from  Maine  to  Florida  along  the  Atlantic  coast,  from 
Canada,  through  several  middle  Western  states,  and  in  the  south 
as  far  west  as  Mississippi.  It  is  interesting  to  find  it  now  in 
Panama  and  not  where  it  would  be  expected  to  come  in  with 
goods  shipped  from  the  north.  The  most  distinctive  features  of 
the  species  are  given  below.

Male:  ALE  considerably  further  from  PLE  than  AME  are 
from  PME  (Fig.  7);  palpal  patella  only  a  little  shorter  than 
palpal  tibia ;  the  conductor  terminates  in  a  broad  distal  piece 
(differing  considerably  from  that  in  northern  forms)  (Fig.  8)  ; 
the  paraeymbium  is  bluntly  rounded  distally;  the  prolateral 
spur  is  indistinctly  bifid;  the  "large  tooth"  is  present  and  the 
other  eheliceral  teeth  are  as  shown  in  Figure  9;  the  fang  has  no 
cusps;  the  abdomen  is  considerably  extended  beyond  the  spin- 
nerets; leg  spines  are  few  and  weak.

Apparently  this  species  has  not  been  studied  since  the  original 
work  done  by  the  Cambridges  and,  hence,  it  seems  desirable  to 
give  a  condensed  description  of  hypotypes  as  follows : 

Male  hypotype.  Total  length  4.160  mm.  exclusive  of  chelicerae ; 
including  chelicerae  4.875  mm.  Abdomen  widest  about  two- 
fifths  from  base ;  does  not  extend  posterior  to  spinnerets.  Legs 
comparatively  robust ;  with  both  spines  and  hairs.  Ratio  of  eyes 
AME  :  ALE  :  PME  :  PLE  =  3.5  :  2.5  :  3.5  :  3.5.  Lateral  eyes 
separated  from  one  another  by  the  diameter  of  ALE.  AME  sep- 
arated from  PME  by  nearly  twice  as  far.  Carapace  longer  than 
basal  segment  of  chelicerae  in  ratio  of  about  3  :  2.  Chelicerae : 
relative^  short  and  robust ;  the  fang  has  a  cusp  on  its  inner 
margin  near  the  base ;  the  prolateral  spur  is  a  simple  and  fairlj- 
robust  spine ;  the  promargin  of  the  fang  groove  has  six  teeth  of 
which  the  second  is  considerably  enlarged  and  could  well  be  con- 
sidered the  "large  tooth"  in  the  usual  sense  but  F.  P.  Cambridge 
did  not  so  regard  it ;  the  retromargin  has  six  teeth  with  the  first 
two  close  together  (Fig.  12).  Legs  with  both  spines  and  hair. 
Palp :  the  tibia  is  only  slightly  longer  than  the  patella ;  the 
paracymbium  is  relatively  short  and  broad  except  terminally 
where  it  narrows  to  a  blunt  apex  (Fig.  13)  ;  the  conductor  is 
broad  throughout  its  length  (Fig.  14).  The  hypotype  male  is 
colored  essentially  like  the  hypotype  female  but  is  lighter 
throughout. 

Hypotype  female.  Total  length  exclusive  of  the  chelicerae 
5.265  mm. ;  inclusive  of  the  chelicerae  5.525  mm.  Abdomen  very 
»il>bous  about  the  middle  (Fig.  15)  ;  gibbosity  lacking  in  some 
individuals  which  may  not  be  mature ;  not  continued  posterior  to 
spinnerets.    Chelicerae :    short,   robust ;   fang  without  inner  or

outer  cusps;  promargin  of  fang  groove  with  seven  teeth1;  retro- 
margin  with  six  (Fig.  16).  Some  variation  in  respect  to  number 
and  placement  of  teeth  has  been  noted  in  both  sexes.  When  the 
female  is  fully  mature  the  genital  fold  appears  as  shown  in 
Figure  17.  The  eyes  are  essentially  as  thev  appear  in  the  male 
(Fig.  18).

This  species  was  described  by  its  author  from  Costa  Rica  with 
great  brevity  and  accompanied  by  a  very  simple  figure  of  the 
male  chelicera.  The  species  has  received  no  attention  since  1909 
and  would  seem  to  deserve  a  detailed  description  which  is  given 
below  in  accord  with  my  usual  formula.

mm. ;  inclusive  of  the  chelicerae  about  10.92  mm.  Carapace  3.12 
mm.  long,  1.722  mm.  wide  opposite  posterior  border  of  second 
coxae  where  it  is  widest ;  cephalic  part  only  slightly  raised ;  with 
other  features  as  usual  in  the  genus. 

Eyes.  Ocular  tubercle  bearing  AME  rather  prominent ;  viewed 
from  above,  both  rows  moderately  recurved;  viewed  from  in 
front,  anterior  row  slightly  recurved,  posterior  row  nearly 
straight,  both  measured  by  centers ;  central  ocular  quadrangle 
wider  behind  than  in  front  in  ratio  of  6  :  5,  wider  behind  than 
long  in  ratio  of  6  :  5.  Ratio  of  eyes  AME  :  ALE  :  PME  :  PLE 
=  6:3:  4.25  :  4.  AME  separated  from  one  another  by  slightly 
more  than  their  diameter,  from  ALE  by  slightly  more  than  1.3 
times  their  diameter.  PME  separated  from  one  another  by 
slightly  less  than  2.5  times  their  diameter,  from  PLE  by  twice 
their  diameter.  Laterals  separated  from  one  another  by  the 
diameter  of  AME.  AME  separated  from  PME  by  slightly  more 
than  the  distance  between  the  laterals  (Fig.  19).  Height  of 
clypeus  equal  to  1.5  times  the  diameter  of  AME. 

Chelicerae.  Strongly  developed,  quite  porrect,  and  moderately 
divergent;  basal  segment  2.73  mm.  long  and,  therefore,  some- 
what shorter  than  carapace ;  fang  long,  slender,  only  slightly 
sinuous,  without  cusps;  the  prolateral  spur  is  simple,  without

(Figures  27-31) 

T.  ethodon  Eoewer,  1942 

As  I  have  pointed  out  elsewhere,  the  females  regarded  by  the 
authors  of  this  species  as  the  allotype  and  paratypes  actually 
belong"  to  T.  tenuissima  0.  P.  Cambridge.  The  absence  of  spines 
on  the  legs,  the  cheliceral  teeth,  and  the  genital  fold  as  well  as 
other  less  marked  characteristics  make  this  identification  certain.

The  holotype  male  appears  to  represent  a  valid  species  and  is 
so  regarded  in  this  paper.  It  seems  strange,  however,  that  only 
one  specimen  has  been  taken  in  view  of  the  repeated  extensive 


CHICKERING:  TETRAGNATHA  IN  PANAMA  317 

collecting  practiced  during  the  past  twenty-eight  years.  The 
male  holotype  is  rather  badly  mutilated  and,  hence,  it  is  impos- 
sible to  describe  it  as  carefully  as  desired.  The  following  items 
may  be  useful  additions  to  the  very  brief  description  given  by 
the  authors  of  the  species. 

Eyes.  Viewed  from  above,  both  rows  moderately  recurved; 
viewed  from  in  front,  anterior  row  nearly  straight  and  posterior 
row  gently  procurved,  both  measured  by  centers.  Central  ocular 
quadrangle  slightly  wider  behind  than  in  front,  slightly  wider 
behind  than  long.  Ratio  of  eyes  AME  :  ALE  :  PME  :  PLE  = 
12  :  8  :  10  :  9.  AME  separated  from  one  another  by  their 
diameter,  from  ALE  by  about  five-fourths  of  their  diameter. 
PME  separated  from  one  another  by  about  1.7  times  their  di- 
ameter, from  PLE  by  slightly  less  than  this.  Laterals  separated 
from  one  another  by  five-fourth's  of  the  diameter  of  ALE.  Lat- 
erals, therefore,  slightly  closer  to  one  another  than  AME  are 
to  PME.  Height  of  clypeus  equal  to  about  five-fourths  of  the 
diameter  of  AME. 

Chelicerae.  The  "large  tooth"  is  present;  the  prolateral  spur 
is  bifid ;  the  chelieeral  teeth  along  the  fang  groove  are  as  shown 
in  Figure  28. 

Palp.  Essentially  as  shown  in  figures  provided  by  the  authors 
of  the  species;  some  details  relating  to  conductor,  embolus,  and 
paracymbium  are  shown  in  Figures  29-31. 

Type  locality.  The  holotype  is  from  Barro  Colorado  Island, 
C.  Z.,  July-August,  1928  (Chickering).  No  other  specimens  have 
come  to  light  during  several  collecting  periods  since  the  finding 
of  the  holotype. 

Tetragnatha  fragilis  sp.  now 
(Figures  32-38) 

Male  holotype.  Total  length  including  chelicerae  5.85  mm., 
exclusive  of  the  chelicerae  5.395  mm.  Carapace  1.527  mm.  long, 
.780  mm.  wide  opposite  second  coxae  where  it  is  widest ;  cephalic 
part  nearly  parallel  sided ;  other  features  as  usual  in  the  genus. 

Eyes.  Eight  in  two  rows  as  usual,  all  dark ;  viewed  from  above, 
both  rows  definitely  recurved ;  viewed  from  in  front,  both  rows 
also  moderately  recurved,  measured  by  centers.  Central  ocular 
quadrangle  wider  behind  than  in  front  in  ratio  of  13  :  11 ;  wider 


318  BULLETIN  :   MUSEUM  OF   COMPARATIVE  ZOOLOGY 

behind  than  long  in  nearly  the  same  ratio.  Ratio  of  eyes  AME 
:  ALE  :  PME  :  PLE  =  7.5  :  5  :  6.5  :  6.  AME  separated  from 
one  another  by  about  six-fifths  of  their  diameter,  from  ALE 
by  four-thirds  of  their  diameter.  PME  separated  from  one  an- 
other by  slightly  more  than  twice  their  diameter,  from  PLE  by 
a  little  more  than  1.5  times  their  diameter.  Laterals  separated 
from  one  another  by  a  little  more  than  twice  the  diameter  of 
PLE.  AME  separated  from  PME  by  slightly  more  than  1.5 
times  the  diameter  of  PME  and,  therefore,  closer  together  than 
ALE  are  to  PLE.  Height  of  clypeus  equal  to  about  the  diameter 
of  AME. 

Chelicerae.  Well  developed;  strongly  divergent;  basal  seg- 
ment .910  mm.  long;  with  a  well-developed  prolateral  spur  hav- 
ing a  pair  of  blunt  terminal  tubercles ;  fang  only  slightly  sinuous 
but  conspicuously  bowed  near  the  middle ;  the  promargin  of  the 
fang  groove  has  the  "large  tooth"  about  one-third  from  the 
distal  end,  a  small  tooth  distal  to  this  and  a  series  of  five  teeth 
proximal  to  it  diminishing  in  size  to  very  minute  at  the  last 
(this  series  appears  to  be  very  variable  among  the  paratypes)  ; 
the  retromargin  has  a  relatively  large  hook-like  tooth  near  the 
base  of  the  fang  and  a  series  of  five  additional  more  proximal 
(only  four  of  these  on  the  right)  (Figs.  32-33)  ;  paratypes  fre- 
quently show  only  three  proximal  to  the  hook-like  tooth  on  the 
retromargin. 

Maxillae.  Nearly  parallel,  somewhat  broadened  distally ;  some- 
what concave  along  lateral  surface  in  distal  quarter ;  longer  than 
lip  in  ratio  of  23  :  10 ;  somewhat  more  than  three  times  as  long 
as  wide  at  narrowest  level. 

Lip.  Longer  than  wide  at  base  in  ratio  of  about  9:8;  sternal 
suture  gently  procurved  ;  with  the  usual  sternal  tubercles  at  ends 
of  sternal  suture. 

Sternum.  Generally  scutif orm ;  moderately  convex;  longer 
than  wide  in  ratio  of  about  37  :  25 ;  moderately  scalloped  opposite 
each  coxa  and  extended  between  all  coxae,  the  second  and  third 
being  relatively  widely  separated ;  continued  as  a  narrow  sclerite 
between  fourth  coxae  which  are  separated  by  only  one-eleventh 
of  their  width. 

Legs.  1243.  Width  of  first  patella  at  "knee"  .198  mm.,  tibial 
index  of  first  leg  4.  Width  of  fourth  patella  at  "knee"  .137  mm., 
tibial  index  of  fourth  leg  5.

True  spines  are  completely  lacking  from  all  legs. 

Palp.  The  tibia  is  slightly  longer  than  patella  but  both  are 
short ;  the  paracymbium  is  distinctly  notched  or  bifid  at  its  apex ; 
the  embolus  describes  nearly  a  circle  on  the  bulb  and  then  ex- 
tends nearly  straight  to  terminate  at  a  point  slightly  beyond

(Figs.  34-35) .  Both  conductor  and  embolus  are  closely  associated 
throughout. 

Abdomen.  Not  continued  posterior  to  spinnerets;  only  slightly 
extended  over  carapace ;  3.802  mm.  long ;  without  any  anterior 
dorsal  notch  at  base ;  very  slender  and  of  nearly  uniform  di- 
ameter throughout ;  a  little  more  than  seven  times  as  long  as 
wide  near  base ;  genital  fold  only  a  transverse  ridge. 

Color  in  alcohol.  Legs  yellowish  with  extensive  fine  dusky  gray 
dotting.  Palps,  chelicerae,  and  maxillae  yellow  with  a  variety  of 
shading.  Lip  and  sternum  yellowish  with  dusky  dotting.  Cara- 
pace yellowish  with  a  broad  irregular  dusky  median  stripe  from 
posterior  border  nearly  to  PLE.  Abdomen :  dorsum  yellowish 
white  with  a  small  median  black  spot  just  above  the  anal  tubercle 
and  four  pairs  of  similar  small  black  dorsolateral  spots  in  the 
posterior  three  fourths  (with  some  irregularities)  ;  there  is  a 
narrow  dark  gray  lateral  stripe  on  each  side;  the  venter  is  a 
dusky  gray. 

Female  allotype.  Total  length  including  chelicerae  7.67  mm.

of  four  teeth  diminishing  in  size  toward  the  proximal  end ; 
retromargin  with  six  teeth  arranged  and  spaced  essentially  as 
shown  in  Figure  37.  As  usual  there  are  variations  in  number  and 
placement  of  cheliceral  teeth  among  the  paratypes;  one  para- 
type  exhibits  the  same  number  and  placement  on  the  promargin 
but  has  seven  teeth  on  the  retromargin  spaced  somewhat  differ- 
ently also  from  those  of  the  allotype.

AME  :  ALE  :  PME  :  PLE  =  4  :  3.25  :  4.75  :  4.  AME  separated 
from  one  another  by  seven-fourths  of  their  diameter,  from  ALE 
by  eleven-fourths  of  their  diameter.  PME  separated  from  one 
another  by  nearly  twice  their  diameter,  from  PLE  by  nearly  the 
same  distance.  Laterals  separated  from  one  another  by  about 
two-thirds  of  the  diameter  of  ALE  and,  therefore,  much  closer 
to  one  another  than  AME  are  to  PME.  Height  of  clypeus  nearly 
equal  to  the  diameter  of  AME.

not  sinuous ;  fang  groove  well  marked ;  promargin  of  fang  groove 
with  seven  teeth,  retromargin  with  seven  and  with  both  sets 
spaced  essentially  as  shown  in  Figure  42.  There  is  no  so-called 
"large  tooth"  on  the  promargin  and  the  two  most  distal  retro- 
marginal  teeth  are  close  together.  Some  variation  in  number  and 
placement  of  teeth  has  been  noted  among  the  paratypes. 

Maxillae.  Nearly  parallel  in  general  but  slightly  divergent  in 
distal  halves;  with  rounded  distal  truncatures;  slightly  concave 
along  lateral  surfaces ;  longer  than  lip  in  ratio  of  about  32  :  15 ; 
about  three  times  as  long  as  wide  at  narrowest  level. 

Lip.  Broader  at  base  than  long  in  ratio  of  about  4:3;  sternal 
suture  gently  procurved ;  with  pronounced  sternal  tubercles  at 
ends  of  suture. 

Sternum.  Generally  scutiform;  moderately  convex;  longer 
than  wide  in  ratio  of  about  5:4;  moderately  scalloped  opposite 
each  coxa  and  produced  between  all  coxae ;  continued  as  a  narrow 
sclerite  between  fourth  coxae  which  are  separated  by  slightly 
more  than  one-third  of  their  width. 

Legs.  1243.  Width  of  first  patella  at  ''knee"  .264  mm.,  tibial

Palp.  The  patella  is  slightly  longer  than  the  tibia  which  has 
the  usual  distal  ehitinized  rim.  The  cymbium  is  long,  slender, 
constricted  in  the  middle  third,  and  much  broader  at  base.  The 
paracymbium  is  also  slender,  club-shaped,  with  a  long  ehitinized 
border  together  with  a  ehitinized  knob  essentially  as  shown  in 
Figures  30-40.  Both  conductor  and  embolus  are  somewhat  spira- 
loid,  closely  associated  throughout  their  length,  and  with  the 
tips  extended  as  a  terminal  hook  (Fig.  41).  The  bulb  is  more 
inflated  than  usual  in  the  genus.

Male  hypotype.  Total  length  including  chelieerae  13  mm.; 
exclusive  of  the  chelieerae  8.10  mm.  Carapace  2.925  mm.  long; 
1.95  mm.  wide  opposite  second  coxae  where  it  is  widest. 

Eyes.  Viewed  from  above,  both  rows  recurved,  anterior  row 
rather  strongly,  posterior  row  moderately.  Viewed  from  in  front, 
anterior  row  moderately  recurved,  posterior  row  slightly  pro- 
curved  (Fig.  53),  both  measured  by  centers.  Central  ocular 
quadrangle  wider  behind  than  in  front  in  ratio  of  23  :  18;  wider 
behind  than  long  in  ratio  of  23  :  39.  Ratio  of  eyes  AME  : 
ALE  :  PME  :  PLE  =  6  :  4.5  :  5  :  5.  AME  separated  from 
one  another  by  their  diameter,  from  ALE  by  about  2.33  times 
their  diameter.  PME  separated  from  one  another  by  twelve- 
fifths  of  their  diameter,  from  PLE  by  2.7  times  their  diameter. 
Laterals  separated  from  one  another  by  about  the  diameter  of 
PLE.  AME  separated  from  PME  by  about  1.33  times  the  di- 
ameter of  AME,  hence  further  from  one  another  than  ALE  are 
from  PLE.  Height  of  elypeus  equal  to  1.5  times  the  diameter 
of  AME. 

Chelieerae.  Very  divergent;  basal  segment  slightly  shorter 
than  carapace.  The  following  features  appear  to  be  particularly 
worthy  of  mention  :  there  is  a  basal  dorsal  cusp  on  the  fang  but 
it  appears  to  be  variable  in  the  degree  to  which  it  is  developed  in 
different  individuals ;  the  prolateral  spur  is  robust  and  shows 
two  tubercles  below  the  apex;  along  the  promargin  of  the  fang 
groove  there  is  a  small  tooth  fairly  close  to  the  spur,  a  hook-like 
tooth  behind  that,  then  the  "large  tooth",  and  this  is  followed 
by  a  series  of  nine  teeth  with  the  last  four  being  very  minute 
(this  is  not  in  agreement  with  statement  by  F.  P.  Cambridge)  ; 
the  retromargin  has  three  teeth  near  the  apex,  then  a  small  tooth 
(not  present  on  the  right  side),  and  this  is  followed  by  seven

teeth  (Fig.  46).  The  spur,  the  three  most  apical  promarginal 
teeth,  and  the  three  most  apical  retromarginal  teeth  appear  to 
be  fairly  consistent  in  their  appearance  in  different  individuals 
but  a  considerable  range  of  variation  has  been  noted  with  respect 
to  the  remaining  teeth. 

Palp.  Tibia  longer  than  patella  in  ratio  of  3  :  2;  conductor 
geniculate  at  beginning  of  apical  third,  somewhat  spoon-shape 
at  apex ;  paracymbium  terminates  in  a  unique  slender  curved 
process  (Figs.  49-51). 

Female  hypotype.  Total  length  including  chelicerae  10.40  mm. 
Abdomen  considerably  swollen  in  anterior  half;  genital  fold  as 
shown  in  Figure  52.

Chelicerae.  The  fang  has  a  dorsal  basal  cusp;  the  promargin 
of  the  fang  groove  has  a  large  apical  tooth,  a  somewhat  smaller 
tooth  considerably  separated  from  the  first,  and  then  after  a 
considerable  space  there  is  a  series  of  five  teeth  diminishing  in 
size  toward  the  proximal  end  of  the  segment;  the  retromargin 
has  a  small  apical  tooth,  a  large  tooth  close  to  it  followed  by  a 
series  of  eight  teeth  with  the  second  and  third  of  this  series

Notes  from  Dr.  W.  J.  Gertsch  suggested  the  synonymy  given 
above.  Comparisons  of  many  specimens  of  both  T.  laboriosa  and 
T.  alba  from  different  localities  have  convinced  me  that  this  is 
correct.  Since  the  species  has  been  described  many  times  and  is 
one  of  the  best  known  in  the  genus  only  those  features  believed 
to  be  most  distinctive  will  be  emphasized  here. 

Distinctive  features:  Male.  ALE  and  PLE  about  as  far  from 
one  another  as  AME  are  from  PME ;  palpal  patella  slightly 
shorter  than  palpal  tibia ;  the  conductor  and  embolus  as  shown  in 
Figures  55-56 ;  the  paracymbium  is  not  divided  distally ;  the 
prolateral  spur  is  robust  and  bifid  distally;  the  "large  tooth" 
is  present  on  the  promargin  of  the  fang  groove  with  other  teeth 
as  shown  in  Figure  57 ;  the  abdomen  is  conspicuously  silvery 
with  alternating  dark  and  silvery  stripes;  of  medium  size,  vary- 
ing from  5  mm.  to  about  6.5  mm. 

Female :  size  varies  from  about  6  mm.  to  about  8  mm.  in 
length ;  the  genital  fold  as  shown  in  Figure  59 ;  the  cheliceral 
teeth  as  shown  in  Figure  58  with  considerable  variation  noted 
among  the  many  individuals  examined;  F.  P.  Cambridge  noted 
a  small  dorsal  basal  cusp  on  the  fang  but  I  have  not  found  this.

All  legs  with  both  hairs  and  spines. 

Palp.  The  tibia  is  only  slightly  longer  than  the  patella  and 
both  are  short ;  the  paracymbium  is  short,  broad,  and  has  a 
somewhat  serrate  distal  margin ;  the  embolus  forms  a  normal 
loop  on  the  bulb  and  then  extends  with  the  rather  broad  con- 
ductor to  its  termination  close  to  the  apex  of  the  cymbium  (Figs. 
G2-64). 

Abdomen.  Not  continued  posterior  to  spinnerets;  extended 
only  slightly  over  the  carapace ;  only  slightly  notched  dorsally 
at  base ;  nearly  uniform  in  width  throughout ;  4.355  mm.  long ; 
.780  mm.  wide  near  base  and,  therefore,  nearly  six  times  as  long 
as  wide. 

Color  in  alcohol.    Legs,  mouth  parts,  and  sternum  all  with

varying  shades  of  yellowish.  Carapace  yellowish  with  a  dusky 
stripe  extending  from  posterior  border  to  the  median  pit  and 
then  continuing  forward  as  a  pair  of  somewhat  diverging  stripes. 
Abdomen :  dorsally  and  dorsolateral^  covered  by  many  yellow- 
ish silvery  spangles;  ventrally  there  are  fewer  of  the  spangles 
with  the  median  area  free  of  these  and  somewhat  transparent. 

Type  locality.  Male  holotype  from  Barro  Colorado  Island, 
C.  Z.,  July,  1954.  Two  paratype  males  from  Madden  Dam  For- 
est, C.  Z.,  July,  1950.   Females  unknown.

F.  P.  Cambridge  had  Keyserling 's  holotype  female  for  study 
and  regarded  it  as  an  immature  specimen.  He  was  certain  that 
T.  longa  0.  P.  Cambridge  was  the  same  species  and  he  had  both 
sexes  for  study.  The  female  reported  by  Banks  (1929)  is  im- 
mature and  its  identification  is  uncertain.  I  have  had  specimens 
from  the  British  Museum  for  comparison  with  mine  and  with 
those  described  by  Chaniberlin  and  Ivie  as  T.  apheles.  It  is  quite 
dear  that  the  female  of  T.  apheles  is  a  recently  moulted  T.  an- 
fillana  Simon.  The  male  appears  to  be  a  T.  mexicana  Keyserling 
and  is  so  regarded  here.  There  may  be  a  single  female  in  my 
collection  which  belongs  to  this  species  but  I  consider  this  un- 
certain. In  view  of  the  confusion  relating  to  this  species  the 
decision  has  been  made  to  give  a  rather  complete  description  of 
a  male  hypotype  in  accord  with  my  usual  procedure. 

Male  hypotype.  Total  length  including  chelicerae  13.455  mm. ; 
exclusive  of  the  chelicerae  11.505  mm.  long.  Carapace  2.925  mm. 
long;  1.625  mm.  wide  opposite  second  coxae  where  it  is  widest; 
generally  slender;  with  lateral  ocular  tubercles  well  separated; 
with  cephalic  region  only  slightly  raised ;  median  pit  irregularly 
circular;  with  a  rather  marked  transverse  groove  between  AME 
and  PME. 

Eyes.  Viewed  from  above,  both  rows  rather  strongly  recurved ; 
viewed  from  in  front,  anterior  row  gently  recurved,  posterior

ocular  quadrangle  wider  behind  than  in  front  in  ratio  of  20  :

from  one  another  by  about  five-fourths  of  their  diameter,  from 
ALE  by  nearly  1.6  times  their  diameter.  PME  separated  from 
one  another  by  about  2.8  times  their  diameter,  from  PLE  by 
nearly  2.25  times  their  diameter.    Laterals  separated  from  one

hence,  closer  to  the  latter  than  the  laterals  are  to  one  another.

of  AME.  The  relative  distances  between  the  different  types  of 
eyes  as  they  are  considered  here  appear  to  be  somewhat  different 
from  those  observed  in  specimens  from  the  British  Museum 
(Natural  History).  These  differences,  however,  are  not  con- 
sidered to  be  particularly  significant. 

Chelicerae.  Divergent;  moderately  slender;  basal  segment 
2.08  mm.  long  and,  therefore,  about  two-thirds  as  long  as  cara- 
pace ;  prolateral  spur  a  simple,  slender  hook,  not  bifid  terminally ; 
fang  slender,  somewhat  sinuous;  fang  groove  with  seven  pro- 
marginal  teeth  and  five  retromarginal  teeth  spaced  essentially 
as  shown  in  Figure  66.  The  two  chelicerae  do  not  agree  in  the 
number  of  teeth  present  along  the  fang  groove.  In  the  hypotype 
the  teeth  on  the  left  are  as  shown  in  the  figure  while  on  the  right 
there  are  only  six  promarginal  teeth  but  there  are  seven  retro- 
marginal  teeth.  This  again  emphasizes  the  unreliability  of  teeth 
as  a  certain  character  for  identification. 

Maxillae.  Essentially  parallel  but  quite  concave  along  outer 
margin  at  the  beginning  of  the  last  third  ;  considerably  broadened 
at  distal  border. 

Lip.  Chitinized  lip  wider  at  base  than  long  in  ratio  of  6  :  5 ; 
sternal  suture  gently  procurved;  with  well-developed  sternal 
tubercles  at  ends  of  sternal  suture. 

Sternum.  Generally  scutiform;  longer  than  wide  in  ratio  of 
7:4;  scalloped  opposite  all  coxae  and  continued  between  all  of 
these  including  the  fourth  which  are  separated  by  a  little  more 
than  one-fifth  of  their  width ;  moderately  convex ;  covered  by 
both  relatively  short  and  long  bristles. 

Legs.  1423.  Width  of  first  patella  at  "knee"  .418  mm.,  tibial 
index  of  first  leg  4.  Width  of  fourth  patella  at  "knee"  .330  mm., 
tibial  index  of  fourth  leg  5.

the  tibia  has  the  usual  ehitiuous  rim  at  distal  end;  the  para- 
cymbium  is  long,  rather  slender,  bluntly  rounded  at  its  distal 
end ;  the  conductor  shows  three  thin  spiraloid  plates  near  its 
middle  and  appears  to  be  somewhat  spiraloid  at  its  distal  end 
(Figs.  67-68).  One  specimen  shows  the  distal  end  of  the  con- 
ductor almost  exactly  as  drawn  by  F.  P.  Cambridge  but  the 
hypotype  appears  somewhat  different.  These  differences  are  re- 
garded as  well  within  the  normal  variation  of  the  species. 

Abdomen.  Long,  slender;  slightly  the  widest  near  base  and 
gradually  tapered  to  posterior  end  which  is  not  extended  beyond 
spinnerets ;  8.385  mm.  long ;  .975  mm.  wide  near  base  and, 
therefore,  more  than  eight  times  as  long  as  wide.  Genital  fold 
(Fig.  70)  nearly  transverse. 

Color  in  alcohol.  Legs  yellowish  with  small  grayish  spots; 
femora  one  and  two  with  an  obscure  prolateral  grayish  stripe. 
Chelicerae  yellowish  white  with  fang  and  teeth  darker.  Maxillae 
yellowish  with  grayish  streaks.  Lip  yellowish  with  grayish  mark- 
ings on  the  strongly  chitinized  portions.  Sternum  with  various 
shades  of  dusty  gray.  Abdomen :  very  light  colored  in  general ; 
dorsum  with  many  irregular  silvery  spangles  and  a  double  series 
of  small  black  dorsolateral  spots;  the  venter  has  the  usual  median 
darker  stripe. 

Two  females  appear  to  go  with  the  males  but  they  are  probably 
immature.  The  general  characteristics  of  females  have  been 
studied  from  specimens  loaned  by  the  British  Museum  (Natural 
History).  From  these  specimens  Figures  69  and  70  have  been 
drawn. 

Type  locality.  The  male  hypotype  is  from  Barro  Colorado 
Island,  C.  Z.,  August,  1939.  Three  other  males  and  probably  two 
immature  females  are  in  the  collection  from  the  same  locality, 
dune  and  August,  1939.

This  species  is  well  known  and  has  been  quite  adequately  de- 
scribed by  several  authors  in  fairly  recent  years  (Seeley,  1928; 
Petrunkevitch,  1930;  Kaston,  1948).  For  this  reason  only  dis- 
tinctive characteristics  and  a  few  figures  will  be  given  in  this 
paper.  Petrunkevitch  (1930)  was  the  first,  so  far  as  I  know,  to 
point  out  that  T.  bid  ens  F.  P.  Cambridge  was  the  same  as  T.

Distinctive  features.  Male:  The  lateral  eyes  are  considerably 
farther  from  one  another  than  AME  are  from  PME  (Fig.  71)  ; 
the  palpal  patella  is  about  three-fourths  as  long  as  the  palpal 
tibia;  the  conductor  is  curiously  sickle-shaped  distally  (Fig. 
73)  ;  the  paracymbium  is  long,  slender,  and  rounded  at  the  apex; 
the  chelicerae  are  nearly  as  long  as  the  carapace ;  the  prolateral 
spur  on  the  basal  segment  of  the  ehelieera  is  unequally  bifid; 
the   "large  tooth"   is  absent   from  the  promargin  of  the  fang

groove ;  the  cheliceral  teeth  are  essentially  as  shown  in  Figure 
72;  in  some  specimens  the  abdomen  appears  to  be  very  slightly 
prolonged  posterior  to  the  spinnerets ;  spines  of  moderate  length 
are  on  all  legs. 

Female.  The  slightly  extended  abdomen  is  somewhat  more 
evident  in  this  sex  than  in  males ;  the  abdomen  is  somewhat  gib- 
bous anteriorly  and  is  notched  dorsally  at  its  base ;  the  cheliceral 
teeth  are  essentially  as  shown  in  Figure  74;  the  genital  fold  is 
essentially  as  shown  in  Figure  75. 

Collection  records.  Both  sexes  have  been  collected  in  the  fol- 
lowing localities  :  Barro  Colorado  Island,  C.  Z.,  June- July,  1934 ; 
February-March,  1936  (W.  J.  Gertsch)  ;  June,  1936;  El  Volcan,

This  species  was  described  from  Bugaba,  Panama,  and  has 
only  been  reported  once  since  that  time  (Banks,  1929)  so  far  as 
I  know. 

Male  hypotype.  Total  length  exclusive  of  the  chelicerae  6.83 
mm. ;  including  the  chelicerae  length  is  8.455  mm.  Carapace  1.755 
mm.  long.  The  whole  body  is  long  and  slender.  The  legs  are  long, 
slender,  and  bear  stout  spines  and  hairs.  Ratio  of  eyes  AME  : 
ALE  :  PME  :  PLE  =  10  :  4  :  5.5  :  5.5.  AME  separated  from 
one  another  by  their  diameter,  from  ALE  by  a  little  more  than 
1.5  times  their  diameter.  PME  separated  from  one  another  by 
slightly  more  than  twice  their  diameter,  from  PLE  by  a  little 
less  than  three  times  their  diameter.  Laterals  separated  from 
one  another  by  a  little  less  than  twice  the  diameter  of  PLE 
(Fig.  76).  AME  separated  from  PME  about  as  far  as  ALE  is 
separated  from  PLE.  The  central  ocular  quadrangle  is  nearly 
square,  only  slightly  longer  than  wide.  Chelicerae :  basal  seg- 
ment 1.722  mm.  long  and,  therefore,  almost  as  long  as  the  cara- 
pace ;  the  fang  has  no  cusps ;  the  promargin  of  the  fang  groove 
has  six  teeth  and  the  retromargin  seven,  all  spaced  essentially 
as  shown  in  Figure  77;  there  is  no  true  "large  tooth"  in  the

usual  sense ;  the  prolateral  spur  is  simple  without  distal  bifurca- 
tion. Palp:  the  tibia  is  longer  than  patella  in  ratio  of  about 
3:2;  the  bulb  is  relatively  short  and  the  cymbium,  conductor, 
and  embolus  are  all  long  and  slender  (Fig.  78).  The  color  in 
both  sexes  is  very  pale  throughout  with  many  yellowish  silvery 
spangles  on  the  abdomen.  A  few  of  the  females  in  the  collection 
have  bright  red  spots  at  the  bases  of  the  spines  and  a  bright  red 
narrow  dorsolateral  stripe  on  each  side  of  the  abdomen.

Male  kolotype.  Total  length  exclusive  of  chelicerae  4.095  mm. ; 
including  chelicerae  4.355  mm.  Carapace  1.27  mm.  long,  .877 
mm.  wide  opposite  intervals  between  second  and  third  coxae 
where  it  is  widest;  anterior  row  of  eyes  occupy  the  full  width 
of  carapace  at  their  level. 

Eyes.  Eight  in  two  rows  as  usual ;  ocular  tubercles  only  moder- 
ately prominent ;  viewed  from  above,  both  rows  recurved,  an- 
terior row  strongly  so  and  posterior  row  moderately ;  viewed 
from  in  front,  anterior  row  gently  recurved,  posterior  row  gently 
procurved,  all  measured  by  centers ;  central  ocular  quadrangle 
wider  behind  than  in  front  in  ratio  of  14  :  11,  wider  behind  than 
long  in  ratio  of  14  :  12.  Ratio  of  eyes  AME  :  ALE  :  PME  : 
PLE  =  4  :  '2.75  :  4  :  3.  AME  separated  from  one  another  and 
from  ALE  by  nearly  five-fourths  of  their  diameter.  PME  sep- 
arated  from  one  another  by  a  little  more  than  five-fourths  of 
their  diameter,  from  PLE  by  about  the  same  distance.  Laterals 
separated  from  one  another  by  the  diameter  of  PLE.  AME  sep- 
arated from  PME  by  slightly  more  than  their  diameter,  hence 
(Fig.  81)  somewhat  farther  apart  than  laterals  are  separated 
from  one  another. 

Cliclicerae.  Short,  robust,  only  slightly  porrect  and  divergent; 
the  fang  is  strongly  sinuous  and  has  a  low  cusp  on  the  inner  sur- 
face and  a  low  tubercle  at  its  base  on  the  dorsal  side;  the  pro- 
lateral  spur  has  moved  into  a  nearly  dorsal  position;  the  pro- 
margin  of  the  fang  groove  has  five  teeth  with  the  first  a  massive 
growth  not  seen  in  any  other  species;  the  retromargin  has  seven

teeth  (Figs.  85-86).  There  is  no  "large  tooth"  in  the  usual 
sense. 

Maxillae.  Nearly  parallel  with  much  less  concavity  along  lat- 
eral borders  than  usual  in  the  genus;  longer  than  lip  in  ratio 
of  9  :  4 ;  not  quite  three  times  as  long  as  wide  in  the  middle. 

Lip.  Wider  at  base  than  long  in  ratio  of  about  3:2;  sternal 
suture  gently  proeurved ;  sternal  tubercles  at  ends  of  sternal 
suture  shorter  and  blunter  than  usual  in  the  genus. 

Sternum.  Rather  strongly  convex;  generally  scutiform;  longer 
than  wide  in  ratio  of  7  :  5;  less  strongly  scalloped  opposite  each 
coxa  than  usual  in  the  genus;  continued  between  fourth  coxae 
which  are  separated  by  one-third  of  their  width.

All  legs  with  both  spines  and  hair. 

Palp.  The  tibia  is  slightly  longer  than  the  patella  and  is  very 
broad ;  both  tibia  and  patella  are  short ;  both  cymbium  and 
paracymbium  appear  to  be  somewhat  distinctively  shaped  (Figs. 
82-84)  ;  the  embolus  and  conductor  appear  to  be  completely  sep- 
arated much  of  their  lengths,  the  former  with  a  conspicuous 
loop  at  the  distal  end  of  the  bulb  and  terminating  in  a  long 
lash-like  apex  (Figs.  82-83). 

Abdomen.  Not  continued  posterior  to  spinnerets;  long,  slender 
and  nearly  uniform  in  width ;  3.90  mm.  long,  .715  mm.  wide  about 
one-third  from  base ;  not  notched  dorsally  at  base. 

Color  in  alcohol.  Generally  a  light  yellowish  throughout ;  the 
carapace  is  dusky  gray  in  the  cephalic  portion,  behind  the  median 
thoracic  pit  and  along  the  lateral  margins.  Abdomen :  the  usual 
characteristic  silvery  spangles  are  few  in  number  in  the  mid- 
dorsal  region  but  are  concentrated  more  or  less  as  a  dorsolateral 
stripe  on  each  side ;  there  is  also  a  row  of  five  or  six  darker  spots 
above  the  dorsolateral  silvery  stripes  on  each  side  and  a  small 
median  blackish  spot  just  above  the  anal  tubercle ;  the  venter  is 
almost  uniformly  yellowish  with  few  yellowish  silvery  spangles. 

Type  locality.  Male  holotype  from  Summit,  C.  Z.,  August, 
1950.  Four  male  paratypes  from  the  same  locality,  August,  1950, 
and  a  single  male  from  the  C.  Z.  Forest  Reserve,  July,  1954 
complete  the  known  list  of  specimens.   The  female  is  unknown.

CHICKERING  :  TETRAGNATHA  IN  PANAMA  343 

This  seems  to  be  a  rare  species  in  collections.  The  Cambridges 
had  it  from  Guatemala  and  Panama.  The  British  Museum 
(Natural  History)  was  unable  to  loan  me  specimens  and  this 
indicated,  I  suppose,  that  only  the  original  types  are  in  that 
institution.  There  is  one  female  in  the  M.  C.  Z.  collection  from 
San  Domingo  (Dominican  Republic)  doubtfully  assigned  to  this 
species.  As  I  have  already  pointed  out,  females  are  often  difficult 
to  identify  with  certainty  but  I  seem  to  have  a  few  specimens 
which  must  be  assigned  to  this  species. 

Female  hypotype.  Total  length  including  chelicerae  10.985 
mm. ;  exclusive  of  chelicerae  9.75  mm.  Carapace  2.73  mm.  long,

AME  separated  from  one  another  by  1.3  times  their  diameter,

porreet,  slightly  divergent;  basal  segment  1.55  mm.  long  and, 
therefore,  only  a  little  more  than  one-half  as  long  as  the  carapace  ; 
fang  without  cusps;  promargin  of  fang  groove  with  seven  teeth; 
retromargin  with  eight  on  right  and  seven  on  left  (Fig.  88)  ; 
teeth  observed  here  not  quite  in  agreement  with  statements  made 
by  F.  P.  Cambridge.  Color :  legs  and  mouth  parts,  except  lip, 
with  varying  shades  of  yellowish ;  lip  reddish  brown ;  sternum 
yellowish ;  the  carapace  has  a  few  dusky  streaks  behind  the 
thoracic  pit  and  in  front  of  it  there  are  two  faint  diverging  dusky 
stripes  passing  toward  the  posterior  eyes ;  on  the  abdomen  dor- 
sally  and  laterally  there  are  many  light  yellowish  silvery  spangles 
surrounded  by  light  semitransparent  reticulations ;  the  spangles 
diminish  toward  the  venter  and  disappear  medially  leaving  a 
rather  narrow  yellowish  stripe  throughout.  The  genital  fold  is 
shown  in  Figure  89. 

Type  locality.  The  female  hypotype  is  from  Barro  Colorado 
Island,  C.  Z.,  Sept.  1939.  Several  other  females  are  in  my  col- 
lection from  the  same  locality,  June,  1936 ;  June  and  August, 
1939.

This  species  is  now  known  to  be  widely  distributed  throughout 
Mexico,  Central  America,  northern  part  of  South  America,  and 
most  of  the  Caribbean  islands.  Petrunkevitch  (1930)  described 
the  most  important  features  of  the  females.  The  most  essential 
characters  of  both  sexes  will  be  summarized  here.  The  species 
occurs  in  my  collections  most  frequently  of  all  species  known 
from  Panama.

therefore,  almost  as  long  as  the  carapace ;  the  fang  is  moderately 
sinuous,  long  and  slender  and  has  no  cusps;  the  prolateral  spur 
is  long,  curved,  with  a  very  small  dorsal  apical  tubercle  and  a 
robust  ventral  apical  tubercle ;  the  promargin  of  the  fang  groove

the  paracymbium  is  short,  bluntly  pointed  at  its  apex  and  has  a 
chitinized  knob  near  the  distal  end ;  the  conductor  and  embolus 
are  finely  attenuated  at  their  tips  (Figs.  92-94).  One  of  the 
most  distinctive  features  in  this  species  is  the  complete  absence 
of  spines  from  the  legs.  The  hair  is  coarse,  however,  and  there 
are  many  bristles.

genital  fold  appears  essentially  as  shown  in  Figure  95.  Cheli- 
eerae :  There  is  a  very  conspicuous  basal  dorsal  cusp  on  the 
fang;  the  fang  has  a  deep  indentation  on  the  inner  side  near 
the  middle  and  is  moderately  sinuous;  the  promargin  of  the  fang 
groove  has  seven  teeth  and  the  retromargin  has  eleven  spaced 
essentially  as  shown  in  Figure  96  (a  considerable  variation  in 
the  teeth  in  different  individuals  has  been  noted)  ;  the  basal  seg- 
ment is  not  quite  as  long  as  the  carapace. 

Type  locality.  The  male  hypotype  is  from  Barro  Colorado

Male  hypotype.  Total  length  including  chelicerae  10.92  mm. ; 
exclusive  of  the  chelicerae  8.775  mm.  Carapace  3.055  mm.  long, 
1.755  mm.  wide  opposite  second  coxae  where  it  is  widest.  First 
row  of  eyes  project  slightly  beyond  the  sides  of  the  carapace; 
the  second  row  occupies  nearly  the  full  width  of  the  carapace 
at  their  level.  Viewed  from  above,  both  rows  of  eyes  recurved, 
posterior  row  slightly,  anterior  row  moderately.  Viewed  from 
in  front,  anterior  row  moderately  recurved,  posterior  row  mod- 
erately procurved,  both  measured  by  centers  (Fig.  97).  Ratio 
of  eyes  AME  :  ALE  :  PME  :  PLE  =  13  :  9  :  11  :  10.  AME 
separated  from  one  another  by  about  their  diameter,  from  ALE 
by  about  1.5  times  their  diameter.  PME  separated  from  one 
another  by  nearly  twice  their  diameter,  from  PLE  by  twice  their 
diameter.  Laterals  separated  from  one  another  by  slightly  more

the  "large  tooth"  with  two  small  teeth  distal  to  it  and  a  series 
of  ten  small  teeth  proximal  to  it ;  the  retromargin  has  a  series  of

and,  apparently,  quite  variable  among  the  numerous  specimens 
available  for  study. 

Palp.  The  tibia  is  almost  twice  as  long  as  the  patella;  the 
paracymbium  is  bluntly  pointed  distally ;  the  distal  end  of  the 
conductor  is  subaculeate  and  slightly  hooked  (Fig.  99). 

The  legs  have  both  spines  and  hairs  some  of  which  are  quite 
erect. 

Female  hypotype.  Total  length  exclusive  of  the  chelicerae 
10.53  mm. ;  inclusive  of  the  chelicerae  13.13  mm.  Abdomen  not 
extended  posterior  to  the  spinnerets;  conspicuously  gibbous  in 
anterior  third  and  concave  along  dorsal  surface.  The  genital 
fold  is  essentially  as  shown  in  Figure  102.  Chelicerae :  there  is 
a  dorsal  basal  cusp  on  the  fang;  there  is  also  an  unusual  dorsal 
distal  tooth  on  the  basal  segment  of  the  chelicera  at  the  base  of 
the  fang;  the  promargin  of  the  fang  groove  has  a  small  and  a 
much  larger  tooth  at  the  distal  end  and,  after  a  considerable 
space,  a  series  of  seven  teeth ;  the  retromargin  has  a  total  of 
thirteen  teeth  spaced  essentially  as  shown  in  Figures  100-101. 
The  exact  number  of  cheliceral  teeth  seems  to  be  quite  variable 
among  the  numerous  specimens  available  for  study.  I  regard 
Chamberlin  and  Ivie's  T.  amplidens  as  one  of  these  with  a 
larger  number  of  teeth  than  heretofore  recognized  in  this  species. 
Basal  segment  of  the  chelicerae  not  quite  as  long  as  the  carapace. 

Type  locality.  Both  hypotypes  are  from  Barro  Colorado  Is- 
land, C.  Z.,  June,  1939.  Numerous  specimens  of  both  sexes  are  in 
my  collection  from  the  following  localities :  Barro  Colorado 
Island,  C.  Z.,  June-July,  1934;  June,  1936;  June-August,  1939; 
June-August,  1950;  July,  1954;  Madden  Dam  Forest,  C.  Z.,

Museum  of  Comparative  Zoology,  compared  them  with  my  speci- 
mens from  Panama.  This  study  has  convinced  me  that  I  have 
been  dealing  with  the  same  species.  There  are  what  I  consider 
minor  differences  in  the  cheliceral  dentition,  possibly  the  eyes 
and  other  features  but  I  think  these  are  all  well  within  the  normal 
range  of  variations  of  a  widely  dispersed  species.  It  seems  in- 
teresting to  find  this  species  so  far  south  in  Central  America 
when  it  has  previously  been  reported  only  from  east  of  the  Rocky 
Mountains  in  the  United  States  and  not  yet  from  the  West 
Indies.

is  wider  behind  than  in  front  in  ratio  of  17  :  15,  wider  behind

nearer  the  base  (Figs.  103-104)  ;  the  promargin  of  the  fang 
groove  has  ten  teeth  the  third  of  which  would  probably  be 
called  the  "large  tooth"  by  F.  P.  Cambridge ;  the  prolateral  spur 
is  slender  and  not  apically  bifid ;  the  retromargin  of  the  fang 
groove  has  eight  teeth.  Palp :  the  tibia,  including  the  chitinous 
extension,  is  only  slightly  longer  than  the  patella;  the  embolus 
extends  in  a  very  loose  spiral  through  the  somewhat  twisted 
conductor  to  terminate  in  a  characteristic  apical  form  (Fig.  105)  ; 
the  paracymbium  is  broad  at  the  base  where  it  is  strongly  chitin- 
ized  but  it  is  very  slender  in  the  distal  half  and  not  notched  at 
its  apex.  Color :  legs,  cephalothorax,  and  mouth  parts  are  all 
yellowish  ;  the  abdomen  is  covered  by  many  yellowish  silvery 
spangles  and  grayish  reticulations ;  the  cardiac  area  has  a  trans- 
parent stripe ;  the  venter  is  also  covered  by  the  yellowish  silvery 
spangles  and  is  without  a  median  stripe  which  is  so  frequently 
present  in  the  genus. 

Female  Ixxjpotxjpe.  Total  length  including  the  chelicerae  12.675 
mm. ;  exclusive  of  the  chelicerae  10.725  mm.  Carapace  2.925  mm. 
long.  Eyes  essentially  as  in  male  (Fig.  106).  Chelicerae:  basal 
segment  1.95  mm.  long,  about  two-thirds  as  long  as  carapace; 
the  fang  has  no  cusps;  the  promargin  of  the  fang  groove  has 
seven  teeth,  the  first  of  which  is  relatively  large ;  the  retromargin 
also  has  seven  teeth,  the  first  of  which  is  small  (Fig.  107)  ;  the 
cheliceral  teeth  are  not  in  close  agreement  with  description  given 
by  Seeley   (1928).    The  genital  fold  is  essentially  as  shown  in

No.  6  —  The  Tenuis  and  Selenophora  Groups  of  the  Ant  Genu* 
Ponera  (Rymenoptera:  Formicidae) 

By  Edward  0.  Wilson 

When  W.  M.  Wheeler  created  the  new  genus  Pseudocryptopone 
(generitype:  Cryptopone  tenuis  Emery)  in  1933,  it  was  with  the 
free  acknowledgment  that  this  entity  could  not  be  clearly  sep- 
arated from  Ponera.  "Indeed,  I  confess  my  inability  to  draw  a 
sharp  line  of  demarcation  between  the  two  genera.  One  of  the 
species,  incerta,  new  species,  which  I  have  assigned  to  Pseudo- 
cry  ptopone,  might,  with  equal  propriety,  be  placed  in  Ponera." 
The  purpose  of  this  exceptional  procedure  was  to  begin  a  pre- 
liminary, orderly  reduction  of  Ponera.  ll Ponera  is  now  a  large 
and  very  difficult  genus  in  great  need  of  careful  revision.  The 
monographer  who  undertakes  this  task  will  very  probably  divide 
it  into  several  subgenera  or  even  genera  and  his  definition  of 
these  will  automatically  determine  their  relations  to  Pseudo- 
cryptopone and  therefore  its  true  status  and  affinities."  In  a 
similar  fashion,  Wheeler  withdrew  two  Papuan  species  of  Ponera 
{selenophora  and  clavicornis)  and  combined  them  with  a  new 
Philippine  species  (oreas)  to  form  a  second  new  genus,  Seleno- 
pone. 

Although  Wheeler's  aim  to  partition  Ponera  and  thereby  sim- 
plify its  classification  was  an  admirable  one,  the  formal  naming 
of  new  genera  on  such  feeble  evidence  as  he  proposed  was  not  well 
justified.  A  more  recent  examination  of  Pseudocryptopone  and 
Selenopone,  along  with  many  of  the  related  Indo-Australian 
species  of  Ponera,  has  convinced  the  present  writer  that 
Wheeler's  genera  cannot  be  maintained  on  the  basis  of  even  the 
most  liberal  criteria.  To  begin,  Pseudocryptopone  is  linked 
to  Ponera  by  the  intermediate  species  Ponera  mocsaryi  Emery, 
which  shows  a  combination  of  Ponera  and  Pseudocryptopone 
characters.  These  two  genera  are  further  linked  by  several  species 
more  closely  allied  to  the  Pseudocryptopone  generitype,  but 
which  tend  strongly  toward  the  more  typical  Ponera  type,  e.g., 
Ponera  incerta  (Wheeler),  P.  ratardorum  Wilson,  and  P.  huonica 
Wilson.  Similarly,  Selenopone  is  linked  to  Ponera  by  the  inter- 
mediate Ponera  syscena  Wilson,  and  is  closely  approached  within 


356  BULLETIN  :   MUSEUM  OF  COMPARATIVE  ZOOLOGY 

the  ranks  of  the  "typical"  Ponera  by  the  species  P.  papuana 
Emery.  Finally,  Pscudocryplopone  and  Selenopone  are  linked 
to  one  another  by  several  more  or  less  intermediate  species, 
including  Ponera  clavicornis  Emery,  P.  tenuis  (Emery),  and 
P.  huonica  Wilson. 

In  short,  there  does  not  appear  at  present  to  be  any  basis  for 
a  generic  split  along  the  lines  proposed  by  Wheeler.  The 
following  synonymy  is  accordingly  proposed: 

Genus     PONERA     Latreille 

Ponera  Latreille,   1804,  Nouv.   Diet.   Hist.   Nat.,  24:    178-179.    Generitype: 
Formica  eoarctata  Latreille  {—Formica  contracta  Latreille),  by  subse- 
quent selection. 
Pseudocryptopone  Wheeler,  1933,  Amer.  Mus.  Nov.,  no.  672:  12-13.   Generi- 
type:   Cryptopone    tenuis    Emery,    original    designation.     NEW    SYN- 
ONYMY. 
Selenopone   Wheeler,    1933,   ibid.,   p.    19.    Generitype:    Ponera    selenophora 
Emery,  original  designation.    NEW  SYNONYMY. 
Pseudocryptopone  and  Selenopone  are  of  course  available  as 
subgeneric  names  if  any  reason  is  found  to  make  formal  sub- 
generic  divisions  in  future  revisions  of  Ponera.   In  the  present 
study,    however,   the    entities   considered    are    the   two    species 
groups  having  affinities  with  P.  tenuis  and  P.  selenophora  re- 
spectively. Both  groups  are  herein  much  enlarged  by  the  addition 
of  a  total  of  ten  new  species,  most  of  which  were  collected  by 
the  author  during  a  recent  research  tour  in  Melanesia.    To  the 
selenophora  group  have  been  added  two  older  species   (scabra, 
sinensis)  which  were  apparently  overlooked  by  Wheeler  in  his 
1933  revision. 

Together  the  tenuis  and  selenophora  groups  comprise  a  large 
and  important  section  (approximately  50  per  cent)  of  the 
Papuan  species  of  Ponera,  but  the  present  evidence  indicates  that 
they  diminish  rapidly  outside  this  area.  In  the  tenuis  group,  a 
single  species  is  known  from  Java  and  one  each  from  the  Caroline 
Islands,  New  Caledonia,  and  southeastern  Australia.  In  the 
selenophora  group,  one  species  each  is  known  from  the  Philip- 
pines, Hongkong,  and  southern  Japan.  It  is  possible  that  other 
described  species  from  outside  the  Papuan  region  may  be  placed 
in  these  two  groups  when  Ponera  is  more  exhaustively  studied. 


WILSON  :  TENUIS  AND  SELENOPHORA  GROUPS  OF  PONERA       357 

At  the  moment  the  greatest  concentration  of  species  for  both 
groups  appears  to  exist  at  intermediate  elevations  (500-1600 
meters)  in  the  mountains  of  New  Guinea.  No  less  than  five 
species,  comprising  25  per  cent  of  the  total  known,  have  been 
collected  in  a  limited  area  around  the  headwaters  of  the  Mongi 
River,  Huon  Peninsula.  Further  collecting  in  similar  areas  in 
other  parts  of  New  Guinea  will  probably  yield  a  large  proportion 
of  the  still  undiscovered  species. 

The  present  contribution  has  been  prepared  as  a  preliminary 
part  of  a  review  of  the  ants  of  Melanesia.  The  remainder  of  the 
species  of  Ponera  will  be  treated  in  a  later  part.  Most  of  the  type 
and  other  material  used  in  this  study  is  deposited  in  the  Museum 
of  Comparative  Zoology  at  Harvard  University.  Other  source 
collections  have  been  the  Emery  Collection  in  Genoa;  Dr.  E.  S. 
Ross'  collection  of  New  Guinea  ants,  deposited  with  the  Cali- 
fornia Academy  of  Sciences;  Dr.  J.  L.  Gressitt's  collection  of 
Melanesian  ants,  deposited  in  the  B.  P.  Bishop  Museum,  Hono- 
lulu ;  and  Miss  L.  E.  Cheesman's  collection  of  New  Hebridean 
ants,  deposited  in  the  British  Museum  of  Natural  History. 

Measurements 

In  the  taxonomy  of  a  genus  such  as  Ponera,  where  species  dif- 
ferences are  for  the  most  part  minute  and  subtle,  exact  measure- 
ments are  necessary  for  accurate  species  diagnoses.  In  the  pres- 
ent study  an  ocular  micrometer  was  used,  and  estimations  were 
made  to  the  nearest  two-tenths  of  a  unit  of  0.0293  mm,  or  to 
0.006  mm.  Thus  the  calculated  maximum  error  is  ±  0.006  mm, 
but  in  practice,  of  course,  the  actual  maximum  error  varies 
around  this  figure  according  to  the  specific  measurement  involved. 
Head  width,  as  defined  below,  is  probably  the  "safest"  measure- 
ment ;  repetitive  measurements  have  shown  that  the  actual  maxi- 
mum error  is  no  more  than  ±  0.006  mm.  Scape  length  and 
petiolar  node  length  are  the  least  reliable  measurements,  but 
even  here  the  actual  maximum  error  probably  does  not  exceed 
four-tenths  of  a  micrometer  unit  either  way,  or  ±  0.012  mm. 

Head  width  (HW).  Worker  and  queen:  the  maximum  width 
of  the  head  held  in  perfect  full  face  and  excluding  the  eyes. 
If  the  eyes  extend  beyond  the  lateral  borders  of  the  head  in  this 
position,  the  measurement  is  taken  across  whatever  parts  of  the 


358  BULLETIN  :   MUSEUM   OF   COMPARATIVE  ZOOLOGY 

lateral  borders  are  left  exposed.  Male:  the  maximum  width  of 
the  head  across  and  including  the  eyes. 

Head  length  (HL).  The  length  of  the  head,  held  in  perfect 
full  face,  measured  from  the  level  of  the  anterionnost  point  of 
the  anterior  clypeal  border  to  the  midpoint  of  the  occipital 
border. 

Scape  length  (8L).  The  maximum  length  of  the  scape  exclu- 
sive of  the  basal  "neck." 

Cephalic  index  (CI).   Head  width  X  100/head  length. 

Scape  index  (SI).    Scape  length  X  100/head  width. 

Pronotal  width  (PW).  The  maximum  width  of  the  pronotum 
measured  from  directly  above  and  at  a  right  angle  to  the  long 
axis  of  the  alitrunk. 

Petiole  height.  The  height  of  the  entire  petiole,  measured 
from  the  level  of  the  crest  of  the  petiolar  node  to  the  level  of  the 
lowermost  point  of  the  subpetiolar  process. 

Petiolar  node  length.  When  the  petiole  is  held  in  exact  side 
view,  the  distance  from  the  midpoint  of  the  curve  where  the 
anterior  face  of  the  node  meets  the  anterior  peduncle  to  the 
midpoint  of  the  curve  where  the  posterior  face  of  the  node 
meets  the  posterior  peduncle. 

Dorsal  petiole  width.  The  width  of  the  petiolar  node  measured 
from  directly  a,bove  the  node  and  at  right  angles  to  the  long 
axis  of  the  body.

length  0.18  mm,  dorsal  petiole  width  0.25  mm.  Mandibles  with 
three  well  developed  teeth  occupying  approximately  the  apical 
two-fifths  of  the  masticatory  border ;  the  remainder  of  the  border 
occupied  by  an  indeterminate  number  of  minute  denticles.  Eyes 
minute,  consisting  of  a  single  ommatidium.  Antennal  club  dis- 
tinctly 4- jointed,  considerably  longer  than  the  entire  remainder 
of  the  funiculus.  Head  seen  in  full-face  view  with  nearly  straight 
sides,  feebly  concave  occipital  border.  Petiolar  node  in  side 
view  massive,  subrectangular,  tapering  only  very  slightly  dor- 
sally  ;  seen  from  directly  above,  its  dorsal  surface  forming  an 
almost  exact  half-circle,  the  posterior  face  concave.  Subpetiolar 
process  somewhat  reduced,  its  apex  right-angular. 

Dorsum  of  head  densely  punctate  and  subopaque  to  opaque ; 
sides  of  head  also  densely  punctate,  but  the  punctures  relatively 
shallow  and  the  surface  feebly  shining.  Entire  dorsal  and  lateral 
surfaces  of  the  alitrunk  covered  by  puncturation  or  shagreening1 
of  variable  density  but  everywhere  shallow  and  feeble,  so  that  the 

i  Shagreening  as  most  rigorously  defined  means  "covered  with  small,  close-set 
tubercles,  suggesting  shagreen  leather,"  or  "with  a  pebbled  surface  like  shagreen 
leather"  (Webster's  International  Dictionary,  unabridged,  second  edition).  In 
the  present  descriptions  I  have  employed  a  somewhat  broader  definition  of  com- 
mon usage  in  entomology,  using  this  term  to  cover  in  addition  to  minute  tubercu- 
lation  and  pebbling  any  dense,  irregular,  minute  sculpturing  which  cannot  more 
precisely  be  described  as  puncturation,  striolation,  vermiculation,  or  reticulation.

surface  varies  from  feebly  to  strongly  shining.  The  dorsal  petiolar 
surface  and  gastric  tergites  are  also  feebly  sculptured  and  their 
surfaces  overall  feebly  shining. 

Body  pilosity  sparse,  being  limited  almost  entirely  to  a  few 
hairs  on  the  anterior  elypeal  border,  posterodorsal  border  of  the 
petiolar  node,  and  entire  surfaces  of  the  gastric  tergites.  Ap- 
pendages mostly  bare,  except  for  terminal  surfaces  of  tibiae  and 
tarsal  segments.  Body  and  appendage  pubescence  everywhere 
dense,  very  short  and  predominantly  oblique  to  appressed. 

Body  concolorous  yellowish  ferruginous;  appendages  light 
brownish  yellow  to  clear  yellow. 

Worker  paratype  variation.  HW  0.38-0.40  mm,  HL  0.51-0.52 
mm,  SL  0,32-0.33  mm,  CI  73-76,  SI  83-86,  PW  0.29-0.30  mm.

CI  76,  SI  87,  maximum  eye  length  0.09  mm,  dorsal  petiole  width 
0.26  mm.  Distinguished  from  the  worker  by  the  usual  queen- 
worker  caste  differences.  As  in  the  queens  of  many  other  species 
of  Ponera,  the  petiolar  node  is  much  thinner  than  in  the  worker 
caste,  forming  distinctly  less  than  a  half-circle  when  viewed 
from  directly  above. 

Relationships.  P.  caledonica  forms  with  P.  exedra  Wilson  of 
Australia  a  discrete  subgroup  of  the  tenuis  group,  characterized 
in  the  worker  caste  by  relatively  large  size,  elongated  head,  thick 
petiolar  node,  and  light  coloration.  The  closest  affinities  of  the 
caledonica  subgroup  are  evidently  with  the  szentivanyi  subgroup 
{szentivanyi  and  petila).  P.  caledonica,  can  be  distinguished  from 
P.  exedra  by  its  smaller  size,  thinner  node,  and  lighter  color. 

Material  examined.  NEW  CALEDONIA :  Ciu,  near  Mt.  Can- 
ala,  300  m.  (type  locality),  January  3,  1955,  berlese  sample  of 
12  workers  and  1  dealate  queen  (E.  O.  Wilson)  ;  Mt.  Mou,  180 
m.,  December  11,  1954,  2  workers  (Wilson,  ace.  no.  128),  and 
berlese  samples  of  Dec.  12  and  27,  1954,  3  workers;  Chapeau 
Gendarme  (Yahoue),  Dec.  7,  1954,  berlese  sample  of  a  single 
worker  (Wilson). 

Ecological  note.  This  is  apparently  a  rather  scarce  cryptobiotic 
species  in  New  Caledonia.  Despite  rather  intensive  hand  collect- 
ing by  the  author  in  the  localities  cited  above,  only  once  (ace. 
no.  128)  was  it  encountered  directly.  In  this  case  two  workers 
were  found  with  a  small  amount  of  brood  in  a  small  cavity  in  the 


364  BULLETIN  :   MUSEUM  OF  COMPARATIVE  ZOOLOGY 

undersurface  of  a  rock  set  deeply  in  the  soil.  These  individuals 
were  rather  sluggish,  and  when  prodded  with  the  tip  of  a  pair 
of  forceps,  rolled  up  and  feigned  deatli  for  a  short  while,  a 
behavioral  response  common  in  other  species  of  Ponera.  All  of  the 
other  collections  of  calcdonica  were  made  by  filtering  the  ants 
from  masses  of  leaf  litter  and  soil  in  a  Berlese  funnel.  The  col- 
lections at  Mt.  Mou  and  Chapeau  Gendarme  were  made  in  rela- 
tively dry,  semi-deciduous,  valley-pocket  forests,  while  that  at 
Ciu  was  in  moister  tropical  evergreen  forest. 

Ponera  exedra  Wilson,  n.  sp. 

Holotype  worker.  HW  0.38  mm,  HL  0.54  mm,  SL  0.34  mm, 
CI  71,  SI  90,  PW  0.32  mm,  petiole  height  0.30  mm,  petiolar  node 
length  0.20  mm,  dorsal  petiole  width  0.24  mm.  This  species  is 
very  close  to  P.  calcdonica  Wilson,  and  is  distinguished  by  its 
slightly  larger  size,  more  elongate  head,  and  longer  scapes,  as 
indicated  in  the  measurements  cited  above.  It  also  has  a  distinctly 
thicker  petiolar  node ;  when  viewed  from  directly  above,  the 
entire  surface  of  the  node  forms  slightly  but  distinctly  more  than 
a  half-circle.  In  addition,  the  subpetiolar  process  is  somewhat 
more  reduced,  and  its  apical  angle  is  obtuse. 

Queen  paratype.  (Tentative  determination).  HW  0.40  mm, 
IIL  0.54  mm,  SL  0.35  mm,  CI  74,  SI  88,  petiolar  node  length 
0.21  mm,  dorsal  petiole  width  0.25  mm.  Distinguished  from  the 
worker  by  the  usual  queen-worker  caste  differences.  Maximum 
eye  length  0.11  mm.  Petiolar  node  thinner  and  more  sharply 
tapering  than  in  worker;  seen  from  directly  above,  the  dorsal 
surface  of  the  node  alone  forms  distinctly  less  than  a  half-circle, 
but  the  entire  node  forms  distinctly  more.  Head  (except  mandi- 
bles) and  first  three  gastric  tergites  medium  brown;  alitrunk 
and  petiole  somewhat  lighter  yellowish  brown;  mandibles  and 
appendages  brownish  yellow  to  clear  yellow. 

Relationships.   See  under  P.  calcdonica. 

Material  examined.  VICTORIA:  Arthurs  Seat  (mountain) 
at  McCrae,  100-300  m.  (type  locality)  ;  April  28,  1951;  a  single 
worker  (W.  L.  Brown).  NEW  SOUTH  WALES:  Pymble; 
October  23,  1950;  a  single  dealate  queen  (Brown). 

Ecological  notes.  Dr.  Brown  has  supplied  me  with  the  follow- 
ing information  relative  to  the  Arthurs  Seat  worker.   This  speci-

men  was  found  under  a  rock  in  granitic  soil  in  a  medium 
rainfall  forest  of  Eucalyptis  viminalis,  E.  radiata  and  Banksia 
sp.  Brown  notes  that  the  ant  fauna  of  Arthurs  Seat  is  unusual 
for  this  part  of  Victoria,  containing  a  number  of  distinctly  north- 
ern elements,  e.  g.  Mayriella  abstinens  Forel  and  Camponotus 
intrepiclus  (Kirby).  Thus  the  discovery  of  the  Ponera  exedra 
queen  at  Pymble,  N.  S.  W.,  hundreds  of  miles  to  the  north,  is  not 
too  surprising.  This  latter  specimen  was  collected  from  beneath 
a  rock  in  medium,  dry  sclerophyll  forest  on  sandstone. 

The  close  affinities  of  P.  exedra  to  P.  caledonica  are  of  con- 
siderable interest,  insomuch  as  they  represent  another  of  a  grow- 
ing series  of  known  links  at  the  species-group  level  between  the 
ant  faunas  of  NewT  Caledonia  and  eastern  Australia. 

Ponera  huonica  Wilson,  n.  sp. 

Holotype  worker.  HW  0.41  mm,  HL  0.49  mm,  SL  0.33  mm. 
CI  84,  SI  81,  petiole  height  0.33  mm,  petiolar  node  length  0.18 
mm,  dorsal  petiole  width  0.22  mm.  Right  mandible  with  three 
teeth  occupying  the  apical  half  of  the  masticatory  border,  a 
smaller  tooth  situated  approximately  midway  between  the  basal- 
most  of  the  apical  teeth  and  the  basal  angle,  and  an  even  smaller, 
barely  distinguishable  tooth  on  the  basal  angle.  There  are  no 
intercalary  denticles  evident  at  magnifications  up  to  100X ; 
higher  magnifications  were  not  used.  The  left  mandible  is 
similar,  but  the  median  tooth  described  above  is  smaller  and 
rudimentary.  Eye  minute,  consisting  of  a  single  ommatidium. 
Antennal  club  massive,  distinctly  4-jointed,  slightly  longer  than 
the  remainder  of  the  funiculus.  Head  shape  about  as  described 
in  P.  szaboi  "Wilson.  Petiolar  node  seen  from  the  side  relatively 
thick,  subrectangular,  tapering  very  little  dorsally;  seen  from 
above  its  dorsal  surface  forms  slightly  more  than  a  half -circle. 
Subpetiolar  process  well-developed,  its  apex  sharply  truncated. 

Mandibles  smooth  and  shining ;  clypeus  somewhat  less  smooth, 
and  feebly  shining;  remainder  of  head  roughly  shagreened  and 
opaque.  Pro-  and  mesonotum  shagreened  to  contiguously  punc- 
tate, and  subopaque ;  episternum  and  various  propodeal  surfaces 
variably  punctate  and  feebly  shining  to  subopaque.  Petiolar  node 
mostly    covered    with    scattered    shallow    punctures,    feebly    to

strongly  shining.  C4astric  tergites  contiguously  punctate  and  sub- 
opaque. 

Pilosity  as  in  P.  calcdonica  but  in  addition  with  a  few  short 
erect  hairs  on  the  occipital  border,  anterior  pronotal  angle, 
and  anterior  gastric  tergital  surfaces.  Pubescence  dense,  short, 
predominantly  oblique  to  appressed. 

Head  (except  mandibles)  medium  brown;  alitrunk,  petiole, 
and  gaster  light  brown,  the  gaster  a  shade  darker  than  the 
rest;  mandibles  and  appendages  light  brown. 

Worker  paratype  variation.  HW  0.40-0.41  mm,  HL  0.48-0.50 
mm,  SL  0.33-0.35  mm,  CI  80-83,  SI  81-87,  PW  0.29-0.32  mm. 
The  unusual  mandibular  dentition  described  for  the  holotype 
occurs  in  most  of  the  paratype  workers.  In  several  it  is  modified 
by  the  addition  of  one  or  two  smaller  intercalary  teeth  or  denti- 
cles on  the  basal  half  of  the  masticatory  border.  In  several  others 
the  two  principal  teeth  of  the  basal  half  are  reduced  to  the  size 
of  normal  (for  the  tenuis  group)  denticles. 

Queen  paratypes.  HW  0.43-0.45  mm,  HL  0.51  mm,  SL  0.35- 
0.36  mm,  CI  84-86,  SI  80-82,  dorsal  petiole  width  0.23-0.24  mm. 
Differing  from  the  worker  caste  by  the  usual  queen-worker 
differences.  Compound  eyes  well  developed,  a,t  least  0.29  mm 
in  maximum  length.  Petiolar  node  notably  more  slender  in 
side  view ;  seen  from  above  its  dorsal  surface  forms  distinctly 
less  than  a  half -circle.    Coloration  similar  to  that  of  worker. 

Male  paratype.  HW  0.43  mm,  HL  0.45  mm,  maximum  eye 
length  0.21  mm,  dorsal  petiole  width  0.14  mm.  Not  differing 
fundamentally  in  morphology  from  known  Ponera  males  outside 
the  tenuis  group.  Antennae  13-jointed.  Mandibles  much  re- 
duced, only  about  0.06  mm  in  length,  edentate,  with  rounded 
apices.  Petiolar  node  seen  from  the  side  forming  roughly  an 
isosceles  triangle,  with  slightly  concave  anterior  and  posterior 
faces  and  rounded  dorsal  crest ;  seen  from  above,  circular  in  out- 
line. Genitalia  exserted.  Parameres  small,  0.14  mm  in  length 
(measured  from  distalmost  edge  of  basiparamere  to  tip  of  para- 
mere),  tapering  distally  to  a  pointed  apex.  Penis  valves  large, 
prominent,  extending  nearly  0.1  mm  beyond  the  dorsal  margin 
of  the  parameres,  their  dorsal  borders  strongly  convex,  almost 
semicircular. 

Entire  body  covered  with  abundant,  relatively  short  (length

never  exceeding  0.06  mm)  oblique  to  erect  hairs,  which  merge 
into  the  equally  abundant  underlying  oblique  pubescence. 
Appendages  almost  entirely  lacking  pilosity,  supplied  instead 
with  dense,  predominantly  oblique  pubescence. 

Body  uniformly  dark  brown ;  appendages  light  to  medium 
brown;   wings   lightly   and   uniformly   infumated. 

Relationships.  This  species  is  closely  allied  to  P.  tenuis 
(Emery)  and  P.  ratardorum  Wilson  (q.v.). 

Material  examined.  P.  huonica  has  thus  far  been  collected 
only  in  a  limited  area  in  the  mountainous  region  around  the 
headwaters  of  the  Mongi  River,  Huon  Peninsula,  northeast 
New  Guinea.  N-E  NEW  GUINEA:  Ebabaang  (type  locality), 
1300-1400  meters,  April  16-18,  1955,  3  workers  (E.  O.  Wilson, 
ace.  no.  826)  and  nest  series  with  2  workers,  2  alate  queens, 
and  a  male  (ace.  no.  827)  ;  Gemeheng,  1300-1500  m.,  April  11-13, 
1955,  worker,  alate  queen,  dealate  queen  (Wilson,  ace.  no. 
791)  ;  Joangeng,  1500  m.,  April  7-8,  1955,  stray  dealate  queen 
(Wilson,  ace.  no.  746). 

Ecological  notes.  Colonies  taken  at  Ebabaang  and  Gemeheng 
were  both  small,  containing  probably  less  than  30  workers.  The 
one  at  Ebabaang  was  found  under  the  moss  layer  covering  the 
upper  surface  of  a  large,  soft,  "rich-red"  log.  The  Gemeheng 
colony  was  in  a  small  log  in  the  same  stage  of  decomposition. 
At  all  localities  the  species  was  found  in  partly  open  areas  at 
the  edge  of  native  trails  running  through  dense,  wet  midmoun- 
tain  rainforest. 

Ponera  incerta   (Wheeler) 

Pseudocryptopone  bncerta  Wheeler,  1933,  Amer.  Mus.  Nov.,  no.  672:  18-19, 
fig.  7,  worker,  queen.    Type  locality:  Depok,  Java. 

The  head  of  the  unique  worker  type  is  now  unfortunately 
missing,  so  that  exact  measurements  of  cephalic  and  antennal 
proportions  could  not  be  taken.  In  the  present  diagnosis  cephalic 
characters  are  taken  from  Wheeler's  original  description. 

PW  0.29  mm,  petiole  height  0.29  mm,  petiole  node  length 
0.15  mm,  dorsal  petiole  width  0.22  mm.  Mandibles  with  three 
apical  teeth,  behind  which  the  masticatory  border  is  "finely 
and  indistinctly  crenulate"  (denticulate?).  Antennal  club 
5-jointed.    Petiolar  node  seen  from  directly  above  forming  dis-

tinctly  less  than  a  half -circle,  with  a  shallowly  concave  posterior 
border.  Subpetiolar  process  well  developed,  its  apical  angle 
acute. 

Body  sculpturing  approximately  as  in  P.  huonica  Wilson 
(q.v.) 

Body  pilosity  pattern  as  in  P.  caledonica  Wilson.  Pubescence 
dense,  short,  predominantly  appressed. 

Body  color  uniformly  yellowish  ferruginous;  legs  clear  yellow. 

Relationships.  This  species  is  probably  most  closely  related  to 
P.  ratardorum  Wilson,  from  which  it  can  be  distinguished  by 
slight  differences  in  the  antennal  club  composition  and  in  petiolar 
node  shape,  and  by  a  strong  color  difference.  It  bears  a  close 
habitus  resemblance  to  P.  szaboi,  but  can  be  easily  distinguished 
from  that  species  by  its  5-jointed  antennal  club,  thinner  petiolar 
node,  and  somewhat  more  strongly  shagreened  alitruncal  dorsum. 

Material  examined.    JAVA :  Depok,  worker  holotype. 

PONERA   PETILA   Wilson,    11.    Sp. 

Holotype  worker.  HW  0.32  mm,  HL  0.41  mm,  SL  0.28  mm, 
CI  78,  SI  88,  PW  0.25  mm,  petiolar  height  0.25  mm,  petiolar  node 
length  0.13  mm,  dorsal  petiole  width  0.18  mm.  Very  similar  to 
P.  szentivanyi  Wilson,  differing  slightly  in  body  and  appendage 
proportions  as  given  in  the  measurements  cited  above,  and  in  the 
much  feebler  body  sculpturing,  which  can  be  described  as  fol- 
lows. Sides  of  head  densely  but  shallowly  punctate,  and  feebly 
shining.  Entire  dorsal  and  lateral  surfaces  of  the  alitrunk  with 
puncturation  or  shagreening  of  variable  density  but  everywhere 
shallow  and  feeble,  so  that  the  surface  is  feebly  to  strongly  shin- 
ing. The  gastric  tergites  are  also  more  feebly  sculptured  than 
in  szentivanyi  and  their  surfaces  overall  feebly  shining. 

Relationships.  Closely  resembling  P.  szentivanyi  Wilson,  as 
detailed  in  the  comparative  description  of  that  species  to  follow. 

Material  examined.  N-E.  NEW  GUINEA :  lower  Busu  River, 
near  Lae;  May  10,  1955;  a  single  worker  (Wilson,  ace.  no.  999). 

Ecological  note.  The  single  worker  was  collected  as  a  stray 
in  the  superficial  layers  of  soil  beneath  a  rotting  log  on  the 
ground  in  primary  lowland  rainforest.

PONERA  RATARDORUM  Wilson,  II.  Sp. 

Holotype  worker.  HW  0.37  mm,  HL  0.47  mm,  SL  0.31  mm, 
CI  79,  SI  84,  PW  0.29  mm,  petiole  height  0.28  mm,  petiolar  node 
length  0.15  mm,  dorsal  petiole  width  0,20  mm.  Mandibles  with 
three  well  developed  teeth  occupying  about  the  apical  two- 
fifths  of  the  masticatory  border;  the  remainder  of  the  border 
occupied  by  a  series  of  minute  denticles.  Eye  minute,  consisting 
of  a  single  ommatidium,  located  approximately  0.8  the  distance 
from  the  lateral  occipital  border  to  the  midpoint  of  the  anterior 
genal  border.  Antennal  club  massive,  indistinctly  5-jointed. 
Petiolar  node  seen  from  side  subrectangular,  tapering  almost 
imperceptibly  dorsally,  the  dorsal  surface  feebly  convex;  the 
dorsal  surface  seen  from  directly  above  forms  distinctly  less 
than  a  half-circle,  and  the  posterior  nodal  border  is  almost  per- 
fectly straight.  Subpetiolar  process  well  developed,  its  apical 
angle  acute. 

Sculpturing  very  similar  to  that  described  for  P.  huonica. 

Pilosity  and  pubescence  as  described  for  P.  caledonica.  Body 
medium  brown,  the  head  and  gaster  a  shade  darker  than  the 
alitrunk  and  petiole.    Appendages  clear  yellow. 

Worker  paratype  variation.  New  Britain  and  New  Hebrides: 
HW  0.36-0.38  mm,  HL  0.46-0.48  mm,  SL  0.30-0.32  mm,  CI  78-80, 
SI  83-86,  PW  0.27-0.30  mm.  Carolines:  HW  0.38  mm,  HL 
0.49  mm,  SL  0.33  mm,  CI  88,  SI  87,  PW  0.29  mm. 

Relationships.  This  species  most  closely  resembles  P.  incerta 
(Wheeler)  of  Java,  differing  in  its  darker  color,  distinctly 
5-jointed  antennal  club  (versus  indistinctly  5-jointed  in  incerta), 
and  straight  posterior  face  of  petiolar  node.  Superficially  P. 
ratardorum  resembles  P.  huonica  Wilson  and  P.  tenuis  (Emery) 
but  can  be  readily  distinguished  from  these  two  species  by  its 
5-jointed  antennal  club  and  much  thinner  petiolar  node. 

Material  examined.  NEW  BRITAIN:  St.  Paul's,  Baining 
Mts.,  Gazelle  Peninsula,  350  m.  (type  locality);  Sept.  5,  1955; 
holotype  and  three  paratype  workers  (J.  L.  Gressitt).  NEW 
HEBRIDES:  Ratard  Plantation,  8  km.  southwest  of  Luganville, 
Espiritu  Santo;  Jan.  7-13,  1955;  two  paratype  workers  (Wilson, 
ace.  no.  348).  CAROLINES  :  Yap  I.,  one  paratype  worker  (R.  J. 
Goss) .  The  holotype  and  two  paratypes  have  been  returned  to  the 
Bishop  Museum,  Honolulu;  the  four  remaining  paratypes  have 


870  BULLETIN  :  MUSEUM  OF  COMPARATIVE  ZOOLOGY 

been  deposited  in  the  Museum  of  Comparative  Zoology  and 
IT.  S.  National  Museum. 

This  species  is  named  in  honor  of  Aubert  and  Suzanne  Rataxd, 
of  Noumea  and  Luganville,  the  writer 's  gracious  hosts  during  his 
brief  stay  in  the  New  Hebrides. 

Ecological  notes.  Dr.  Gressitt's  New  Britain  specimens  were 
taken  from  a  rainforest  humus  berlesate.  The  present  writer's 
New  Hebrides  specimens  were  found  foraging  during  the  day 
in  leaf  litter  on  the  floor  of  primary  coastal  rainforest. 

Ponera  swezeyi    (Wheeler) 

Pseudocryptopone  swezeyi  Wheeler,  1933,  Amer.  Mus.  Nov.,  no.  672:  16-17, 
fig.  6,  worker,  queen.    Type  locality:   vicinity  of  Honolulu,  Hawaii. 

The  following  measurements  and  descriptive  notes  are  based 
on  three  worker  syntypes  in  the  Museum  of  Comparative  Zoology. 

HW  0.29-0.30  mm,  HL  0.38-0.41  mm,  SL  0.25-0.26  mm,  CI 
72-78,  SI  84-85,  PW  0.21-0.24  mm,  petiole  height  (single  meas- 
urement) 0.24  mm,  dorsal  petiole  width  0.18  mm.  Mandible  with 
three  distinct  apical  teeth  occupying  slightly  less  than  half  the 
masticatory  border;  the  remainder  of  the  border  bearing  an  in- 
determinate number  of  minute  denticles.  Antennal  club  dis- 
tinctly 5-jointed.  Petiolar  node  seen  from  directly  above  forming 
slightly  more  than  a  half -circle.  Subpetiolar  process  well  de- 
veloped, its  apex  right-angular. 

Sculpturing  about  as  in  P.  caledonica  except  that  on  the  ali- 
trunk  only  the  declivitous  faces  of  the  propodeum  are  smooth 
and  shining,  the  remainder  of  the  alitruneal  surfaces  being 
lightly  shagreened  and  only  feebly  shining. 

Body  concolorous  light  brownish  yellow ;  appendages  clear 
yellow. 

Relationships.  This  distinctive  little  species  does  not  appear  to 
be  closely  related  to  any  of  the  other  known  members  of  the 
tenuis  group. 

Material  examined.  HAWAII :  vicinity  of  Honolulu,  3  syntype 
workers  (R.  H.  Van  Zwaluwenburg)  ;  Herring  Valley,  Honolulu 
(F.  X.  Williams). 

Note  on  distribution.  This  species  is  known  only  from  material 
collected  in  the  vicinity  of  Honolulu.  The  habitat  of  the  type 
series,  "soil  of  cultivated  and  fallow  sugar-cane  fields,"  suggests 


WILSON:  TENUIS  AND  SELENOPHORA  GROUPS  OP  PONERA      3 7 1 

that  it  may  have  been  introduced  by  man  into  the  Hawaiian 
Islands.  Future  collecting  may  show  that  its  native  range  lies 
somewhere  in  the  "source  areas"  of  Melanesia  or  the  East  Indies.

The  description  offered  below  is  based  on  two  workers  collected 
by  myself  in  the  vicinity  of  the  lower  Busu  River,  N-E.  New- 
Guinea.  These  correspond  well  to  Szabo 's  description  and  figure, 
differing  only  in  having  somewhat  more  elongate  heads  than 
shown  by  Szabo. 

HW  0.30-0.31  mm ;  HL  0.40  mm ;  SL  0.25  mm ;  CI  76-78 ;  SI 
79-83;  P\V  0.23  mm;  petiole  height  (single  measurement)  0.24 
mm;  petiolar  node  length  0.15  mm;  dorsal  petiole  width  (single 
measurement)  0.15  mm.  Mandible  linear-subtriangular.  The 
apical  half  of  the  masticatory  border  occupied  by  three  distinct, 
acute  teeth ;  the  basal  half  occupied  by  an  indeterminate  number 
of  minute  denticles.  Eyes  minute,  consisting  of  a  single  omma- 
tidium.  Antennal  club  massive,  distinctly  4-jointed,  consider- 
ably longer  than  the  entire  remainder  of  the  funiculus.  Head 
in  full-face  view  subrectangular,  with  very  feebly  convex  sides 
and  feebly  concave  posterior  border.  Petiolar  node  seen  from 
the  side  relatively  thick,  tapering  slightly  dorsally,  with  a  feebly 
convex  dorsal  border ;  seen  from  directly  above,  with  the  posterior 
face  aligned  with  the  plane  of  vision,  the  node  forms  distinctly 
more  than  a  half-circle,  and  the  posterior  border  appears  almost 
perfectly  straight.  Subpetiolar  process  well-developed,  its  apical 
angle  obtuse. 

Mandibles  smooth  and  shining ;  clypeus  smooth  and  feebly 
shining;  remainder  of  head  finely  and  evenly  shagreened  and 
subopaque.  All  of  alitruncal  surfaces  finely  shagreened  and 
subopaque,  except  the  episterna  and  declivitous  faces  of  the 
propodeum,  which  bear  only  scattered  fine  punctures  and  are 
relatively  smooth  and  more  or  less  shining.  Various  surfaces  of 
the  petiolar  node  bearing  variably  dense  but  fine  and  separated 


372  BULLETIN  :  MUSEUM  OF  COMPARATIVE  ZOOLOGY 

punctures,  and  otherwise  smooth  and  more  or  less  shining. 
Gastric  tergital  surfaces  shagreened  and  subopaque,  except  for 
the  anterior  declivity  of  the  first  gastric  tergite,  which  is  smoother 
and  feebly  shining. 

Pilosity  and  pubescence  as  described  for  P.  caledonica  Wilson. 

Alitrunk  and  petiole  yellowish  brown ;  head  and  gaster  some- 
what darker,  approaching  medium  brown ;  appendages  nearly 
clear  yellow. 

Relationships.  In  its  distinctive  combination  of  characters 
in  size,  petiole  form,  and  body  color,  szaboi  stands  well  apart 
from  all  the  other  known  species  of  the  tenuis  group. 

Material  examined.  N-E.  NEW  GUINEA :  lower  Busu  River, 
near  Lae,  2  workers  (Wilson,  ace.  nos.  963,  1024). 

Ecological  note.  Both  of  the  Busu  River  specimens  were  taken 
as  strays  on  the  floor  of  primary  lowland  rainforest. 

PONERA   SZENTIVANYI  Wilson,   n.   sp. 

Holotype  worker.  IIW  0.34  mm;  HL  0.45  mm,  SL  0.32  mm, 
CI  76,  SI  94,  PW  0.28  mm  (petiole  height  not  measured;  see 
paratype),  petiolar  node  length  0.16  mm,  dorsal  petiole  width 
0.24  mm.  Three  well  developed  teeth  occupying  the  apical  two- 
fifths  of  the  masticatory  border,  followed  basally  by  an  indeter- 
minate number  of  minute  denticles.  Eye  minute,  consisting  of  a 
single  ommatidium,  located  about  0.8  the  distance  from  the  lateral 
occipital  border  to  the  midpoint  of  the  anterior  genal  border. 
Antennal  club  distinctly  4-jointed,  considerably  longer  than  the 
remainder  of  the  funiculus.  Head  elongate  (CI  76)  with  very 
feebly  convex  sides,  and  feebly  but  distinctly  concave  occipital 
border.  Petiolar  node  seen  from  side  relatively  thin,  elongate- 
trapezoidal;  seen  from  directly  above,  so  that  the  posterior  face 
is  exactly  parallel  with  the  line  of  vision,  the  node  as  a  whole 
forms  slightly  more  than  a  half-circle,  but  the  dorsal  surface 
alone  forms  much  less  than  a  half-circle ;  seen  from  the  preceding 
position  the  posterior  face  is  feebly  but  distinctly  concave. 
Subpetiolar  process  somewhat  reduced,  its  apex  right-angular. 

Body  sculpturing  approximately  as  described  for  P.  huonica 
Wilson. 

Pilosity  and  pubescence  as  in  P.  caledonica  Wilson. 


WILSON  :  TENUIS  AND  SELENOPHORA  GROUPS  OF  PONERA      373 

Body  uniformly  light  brownish  yellow;  appendages  clear 
yellow. 

Paratype  worker.  A  single  callow  worker  taken  with  the 
holotype  has  the  integument  of  the  head  somewhat  crumpled 
and  distorted  through  drying,  so  that  regular  cephalic  measure- 
ments could  not  be  made.  PW  0.28  mm,  petiole  height  0.29  mm, 
dorsal  petiole  width  0.21  mm.    Body  color  clear,  pale  yellow. 

Relationships.  This  species  most  closely  resembles  P.  petila 
Wilson,  as  indicated  under  the  comparative  description  of  that 
species.  Together  szentivanyi  and  petila  form  a  subgroup  of  their 
own  within  the  tenuis  group,  characterized  in  the  worker  caste 
by  intermediate  size,  slender  body  form  with  elongate  head,  thin 
petiolar  node,  and  brownish  yellow  body  color.  They  are  closest 
to  the  subgroup  formed  by  P.  caledonica  Wilson  and  P.  exedra 
Wilson,  from  which  they  can  be  distinguished  by  their  smaller 
size  and  thinner  petiolar  node. 

Material  examined.  PAPUA :  Karema,  near  the  Brown  River, 
about  30  miles  north  of  Port  Moresby;  March  8-11,  1955;  holo- 
type and  single  paratype  worker  (Wilson,  ace.  no.  563).  This 
species  is  named  in  honor  of  Dr.  J.  H.  Szent-Ivany,  the  expert 
resident  entomologist  of  the  Territory  of  Papua-New  Guinea, 
whose  friendly  assistance  greatly  aided  the  author's  field  work 
in  this  area. 

Ecological  note.  The  two  type  workers  were  taken  close  to- 
gether on  the  floor  of  primary  lowland  rainforest.

the  border.  Eyes  minute,  consisting  of  a  single  ommatidium. 
Antennal  club  massive,  distinctly  4-jointed,  considerably  longer 
than  the  remainder  of  the  funiculus.  Petiolar  node  seen  from 
the  side  subtrapezoidal,  tapering  slightly  dorsally,  with  a  con- 
vex dorsal  margin,  its  dorsal  surface  seen  from  directly  above 
forming  almost  exactly  a  half-circle  or  very  slightly  less.  An- 
terior half  of  subpetiolar  process  perforated  by  a  small,  median 
hole ;  the  posterior  apex  of  the  process  forming  an  acute  angle. 

Sculpturing  as  described  for  P.  huo7iica  Wilson. 

Pilosity  and  pubescence  as  described  for  P.  huonica,  except 
that  erect  hairs  are  lacking  from  the  occiput  and  pronotum; 
these  missing  hairs  may  well  have  been  rubbed  off  in  this 
specimen,  because  they  are  present  in  more  recently  collected 
material  determined  as  tenuis. 

Body  uniformly  yellowish  brown,  appendages  clear  yellow 
(specimen  possibly  faded;  see  below). 

Variation  in  other  worker  series.  The  following  measurements 
are  based  on  three  workers  from  a  single  nest  series  collected  at 
Ebabaang:  HW  0.42-0.43  mm,  HL  0.49-0.52  mm,  SL  0.33-0.35 
mm,  CI  82-86,  SI  78-83,  PW  0.32  mm.  In  these  specimens  the 
anterior  half  of  the  subpetiolar  process  is  not  perforated  as  in 
the  lectotype,  and  the  posterior  angle  of  the  process  forms 
a  right  angle  instead  of  an  acute  angle.  The  body  color 
is  uniformly  blackish  brown,  and  the  appendage  color  is  light 
yellowish  brown;  there  is  an  excellent  possibility  that  the  con- 
siderably lighter  color  of  the  lectotype  is  due  to  fading. 

Queen  (tentative  determination).  IIW  0.50  mm,  HL  0.58  mm, 
SL  0.40  mm,  CI  86,  SI  80,  dorsal  petiole  width  0.27  mm.  Dif- 
fering from  the  worker  by  the  usual  formicid  queen-worker 
differences.  Maximum  eye  length  0.15  mm.  Petiolar  node  much 
thinner  than  in  worker,  seen  from  directly  above  forming  much 
less  than  a  half-circle.  Distinguished  from  the  queen  of  P. 
huonica  by  its  larger  size,  darker  body  color  (uniformly  blackish 
brown  as  opposed  to  predominantly  medium  brown  in  huonica), 
and  somewhat  thinner  petiolar  node. 

Relationships.  P.  tenuis  most  closely  resembles  P.  huonica 
Wilson,  from  which  it  differs  principally  in  its  more  conventional 
mandibular  dentition,  thinner  petiolar  node,  differently  shaped 
subpetiolar  process,  and  darker  body  color.  Together  these  two 
species  bear  a  close  habitus  resemblance  to  P.  clavicornis  Emery,

and  may  in  fact  provide  a  link  between  the  tenuis  and  seleno- 
phora  species  groups. 

Material  examined.  N-E.  NEW  GUINEA:  (Lemien  or  Ta- 
mara  I.),  lectotype  worker;  Ebabaang,  Mongi  River  Watershed, 
1300-1400  m.,  3  workers  (Wilson,  ace.  no.  828)  ;  Joangeng,  near 
Ebabaang,  1500  m.,  a  stray  dealate  queen  (Wilson,  ace.  no.  746). 

Ecological  note.  The  Ebabaang  workers  were  found  foraging 
during  the  day  in  leaf  litter  on  the  floor  of  midmountain  rain- 
forest. 

Ponera  zwaluwenburgi  (Wheeler) 

Pseudocryptoponc  zwaluwenburgi  Wheeler,  1933,  Amer.  Mus.  Nov.,  no.  672: 
14-16,  fig.  5,  worker.  Type  locality:  Oahu  Island,  Hawaii  (by  present 
selection). 

The  following  measurements  and  descriptive  notes  are  based 
on  four  worker  syntypes  in  the  Museum  of  Comparative  Zoology. 

HW  0.44-0.47  mm,  HL  0.53-0.59  mm,  SL  0.38-0.42  mm,  CI 
81-84,  SI  87-88,  PW  0.32-0.35  mm,  petiole  height  (single  meas- 
urement) 0.28  mm,  dorsal  petiole  width  0.20-0.23  mm.  Mandibles 
with  three  well  developed  teeth  occupying  less  than  half  the 
masticatory  border,  the  remainder  being  occupied  by  an  inde- 
terminate number  of  minute  denticles.  Antennal  club  indistinctly 
5-jointed.  Petiolar  node  seen  from  directly  above  forming  dis- 
tinctly more  than  a  half-circle.  Subpetiolar  process  reduced  to 
a  mere  convexity. 

Entire  body  finely  and  densely  shagreened  and  subopaque. 
except  the  mandibles,  posterior  face  of  the  propodeum,  and 
posterior  face  of  the  petiola,r  node,  which  are  relatively  smooth 
and  shining. 

Short  erect  hairs  numerous  on  anterior  scape  surface,  entire 
dorsum  of  alitrunk,  petiolar  dorsum,  and  entire  surfaces  of  ex- 
posed gastric  tergites.  Pubescence  everywhere  abundant,  almost 
entirely  appressed. 

Body  and  appendages  concolorous  clear  yellow. 

Relationships.  This  species,  marked  by  its  combination  of 
large  size,  lack  of  eyes,  abundant  erect  pilosity,  and  pale  color, 
does  not  appear  to  stand  close  to  any  of  the  other  species  of  the 
tenuis  group. 

Material  examined.    HAWAII :  Oahu,  four  syntype  workers. 


376  BULLETIN  :   MUSEUM  OF  COMPARATIVE  ZOOLOGY 

This  species  is  known  only  from  the  type  material,  which  was 
collected  at  several  localities  on  Oahu  and  on  Maui.  As  in  P. 
sivezeyi,  the  collections  were  all  made  from  the  soil  of  cultivated 
and  fallow  sugar-cane  fields,  a  circumstance  which  suggests  that 
the  species  may  have  been  introduced  into  Hawaii  by  man. 

Characterization  of  the  Ponera  selenophora  group 

Worker.  Medium-sized  species,  worker  head  width  ranging 
between  0.43  and  0.68  mm.  Mandibular  dentition  variable,  in 
most  cases  consisting  of  three  distinct  teeth  occupying  the  apical 
two-fifths  to  one-half  of  the  masticatory  border,  followed  by  a 
series  of  minute  denticles;  in  one  case  (selenophora)  the  basal 
half  of  the  border  bears  two  distinct  teeth  in  addition  to  the 
denticles.  Eyes  usually  small,  with  3-5  indistinct  facets;  in  one 
case  (elegantula)  there  are  11-12  facets.  Junction  of  posterior 
and  lateral  faces  of  propodeum  marginate,  forming  an  angle 
of  80°  to  slightly  less  than  90°.  Petiolar  node  massive  and  ex- 
ceptionally broad,  its  dorsal  width  never  less  than  0.77  X  the 
pronotal  width  and  usually  much  more ;  arcuate  or  crescentic, 
with  the  junction  of  the  anterior  and  posterior  faces  usually 
marginate.  Subpetiolar  process  very  variable  in  shape,  from  well 
developed  and  angular  or  subangular  to  rudimentary  and 
rounded;  when  well  developed,  its  apex  generally  projects  pos- 
teriorly. 

Key  to  the  species  of  the  Ponera 
selenophora  group,  based  on  the  worker 

1.  Small  species,  head  width  0.43-0.47  mm;  dorsum  of  alitrunk  completely 

devoid  of  standing  hairs;    (Xew  Guinea  to  New  Hebrides)    

clavieornis  Emery

Worker.  HW  0.43-0.47  mm,  HL  0.52-0.59  mm,  SL  0.35-0.42 
mm,  CI  81-85,  SI  80-89,  PW  0.32-0.37  mm,  dorsal  petiole  width 
0.27-0.32  mm.  Mandibles  with  three  well  developed  teeth  occupy- 
ing about  the  apical  half  of  the  masticatory  border;  the  basal 
half  occupied  by  an  indeterminate  number  of  minute  denticles. 
Eye  as  described  for  P.  selenophora.  Antennal  club  relatively 
slender,  5-jointed.  Posterolateral  margins  of  propodeum  rela- 
tively poorly  defined,  seen  from  directly  above  forming  an  angle 
of  only  slightly  less  than  90°.  Posterior  face  of  petiolar  node 
seen  from  directly  above  almost  perfectly  straight.  Subpetiolar 
process  variable  in  shape,  ranging  from  a  rudimentary  convexity 
to  a  strong  right-angular  projection. 

Mandibles  smooth  and  shining ;  clypeus  feebly  shagreened  and 
shining  over  most  of  its  surface ;  entire  remainder  of  the  head 
densely,  finely,  and  evenly  punctate  (the  punctures  mostly  under 
0.01  mm  in  diameter)  and  completely  opaque.  Entire  dorsal  and 
lateral  alitruncal  surfaces  similarly  punctate  and  opaque,  except 
for  the  ventral  margins  of  the  sides  of  the  pronotum,  a  limited 
central  longitudinal  strip  on  the  sides  of  the  propodeum,  and 
the  lower  half  of  the  posterior  propodeal  face,  which  surfaces 
are  more  or  less  smooth  and  shining.  Dorsal  and  lateral  surfaces 
of  petiolar  node  somewhat  less  densely  punctate  than  head  and 
alitrunk,  subopaque;  anterior  and  posterior  faces  more  or  less 
smooth  and  shining.  First  several  gastric  tergites  also  somewhat 
less  densely  punctate,  subopaque  to  feebly  shining. 

Pilosity  completely  lacking  on  head  and  alitrunk  except  for 
a  few  erect  hairs  on  the  mandibles,  clypeus,  and  frontal  lobe 
area.  Petiolar  node  and  first  two  gastric  tergites  bare  to  sparsely 
pilose;  terminal  gastric  tergites  and  all  gastric  sternites  abund- 
antly pilose. 

Body  (except  mandibles  and  apical  gastric  segments)  piceous 
brown,  approaching  jet  black.  Mandibles,  apical  gastric  seg- 
ments, and  appendages  yellowish  brown. 

Geographic  variation.  The  series  from  Espiritu  Santo,  New 
Hebrides,  have  somewhat  longer  scapes  than  those  from  New 
Guinea  (SI  86-89  as  opposed  to  80-84). 

The  series  from  Bisianumu,  Papua,  have  the  first  two  gastric 
tergites  pilose ;  in  side  view  5-10  standing  hairs  are  visible  along 
the  profile  of  the  first  tergite.  The  series  from  Tumnang,  N-E. 
New  Guinea,  and  from  the  New  Hebrides  have  the  first  two 


WILSON  :  TENUIS  AND  SELENOPHORA  GROUPS  OF  PONERA      379 

gastric  tergites  bare  of  pilosity.  The  series  from  Bubia,  N-E. 
New  Guinea,  a  geographically  intermediate  locality,  has  the 
tergites  intermediately  pilose:  1-3  standing  hairs  are  visible 
along  the  profile  of  the  first  tergite. 

Relationships.  This  is  a  very  distinct  species,  easily  separated 
in  the  worker  caste  from  other  members  of  the  selenophora  group 
by  the  combination  of  smaller  size,  distinctive  sculpturing,  and 
sparse  body  pilosity.

Ecological  notes.  This  is  an  exceptionally  adaptable  and 
widespread  species.  It  has  been  collected  from  primary  lowland 
rainforest  (Espiritu  Santo),  second-growth  lowland  rainforest 
(Bubia),  foothills  forest  (Bisianumu),  and  true  midmountain 
forest  (Tumnang),  under  a  variety  of  local  ecological  conditions. 

My  accession  no.  608  (Bisianumu)  was  a  small  colony  found 
nesting  under  the  bark  of  a  large  ' '  passalid-stage "  log  on  the 
ground ;  larvae  at  various  stages  of  development  and  cocoons 
were  present.  The  other  two  Bisianumu  accessions  and  the 
Bubia  accession  consisted  of  stray  workers,  also  from  large 
passalid-stage  logs.  The  Tumnang  and  New  Hebrides  specimens 
were  taken  as  strays  in  leaf  litter  on  the  forest  floor.

ner than  in  any  other  selenophora  group  member,  although  ex- 
hibiting the  form  and  exceptional  transverse  width  typical  for 
the  group.  Seen  from  directly  above,  the  dorsal  surface  of  the 
node  is  thin  and  arc-shaped. 

Mandibles  smooth  and  feebly  shining;  clypeus  for  the  most 
part  smooth  and  feebly  shining.  Kemainder  of  head  covered 
by  punctures  which  are  about  0.006  mm  in  diameter  and  sep- 
arated from  one  another  by  about  the  same  distance ;  its  surface

worker  caste  differences.  Maximum  eye  length  0.16  mm.  Unlike 
the  queens  of  other  members  of  the  tenuis  and  selenophora 
groups,  the  queen  of  elegant  ula  does  not  have  a  proportionately 
more  slender  petiolar  node  than  the  worker.

related   to   the   members   of  the  selenophora   "subgroup"    (see 
under  selenophora)  and  distinguished  principally  by  the  follow- 
ing characters : 

(1)  Somewhat  smaller  size. 

(2)  The  antennal  club  is  f our- jointed ;  the  fifth  funicular 
segment  from  the  apex  is  slightly  larger  than  the  succeeding  basal 
segments,  but  still  not  large  enough  to  be  considered  part  of  the 
club,  as  is  the  case  in  P.  sinensis.

group" (see  under  selenophora) ,  and  can  easily  be  distinguished 
from  it  by  the  following  two  characters: 

(1)  The  head  is  proportionately  longer  (maximum  CI  is  82 
as  opposed  to  a  minimum  of  85  in  the  selenophora  subgroup).

several  irregular  denticles  in  the  interdentary  spaces  of  the 
basal  half  of  the  border.  Eyes  minute,  consisting  of  two  or  three 
small,  ill-defined  ommatidia,  located  approximately  0.8  the  dis- 
tance from  the  lateral  occipital  border  to  the  midpoint  of  the 
anterior  genal  border.  The  antenna  lacks  a  well-defined  club, 
the  funicular  segments  merely  increasing  gradually  in  length 
and  width  from  the  fourth  outward.  Posterolateral  margins  of 
propodeum  (line  of  juncture  of  posterior  and  lateral  faces)  well

pilosity  and  pubescence  than  in  selenophora.  Thirteen  to  seven- 
teen outstanding  erect,  hairs  can  be  counted  along  the  outer  sur- 
faces of  the  scapes  in  the  syscena  type,  whereas  there  are  no 
more  than  five  or  six  in  selenophora.  P.  sinensis  is  close  to  P. 
syscena  in  this  character. 

(5)  Dentition  of  basal  half  of  masticatory  border  of  mandible 
bearing  only  denticles. 

Relationships.  See  comparative  description  above.  Although 
this  species  closely  resembles  P.  selenophora  in  most  characters, 
it  has  a  petiolar  node  form  (q.  v.)  which  is  intermediate  between 
the  distinctive  selenophora  type  and  the  more  generalized  type 
characterizing  most  of  the  species  of  Ponera. 

Material  examined.  N-E.  NEW  GUINEA:  native  trail  be- 
tween Yunzain  and  Joangeng,  Mongi  Watershed,  Huon  Penin- 
sula,, 1300  m.j  April  7,  1955;  a  single  worker  (Wilson). 

Ecological  note.  The  unique  type  was  taken  as  a  stray  on  the 
floor  of  midmountain  rainforest. 

Ponera  xenagos  Wilson,  n.  sp. 

Holotype  worker.  HW  0.67  mm,  HL  0.77  mm,  SL  0.59  mm, 
CI  87,  SI  88,  PW  0.52  mm,  petiole  height  0.53  mm,  petiolar  node 
length  0.27  mm,  dorsal  petiole  width  0.42  mm.  Very  similar  to 
P.  selenophora  Emery,  differing  by  the  following  characters : 

(1)  Larger  size. 

(2)  The  three  apical  mandibular  teeth  occupy  less  than  half 
the  masticatory  border,  and  distinct  teeth  are  not  developed  on 
the  basal  half  of  the  border  as  described  for  selenophora. 

(3)  The  posterolateral  margins  of  the  propodeum  are  less 
pronounced;  viewed  from  directly  above  they  form  an  angle  of 
only  a  little  less  than  90°. 

(4)  When  viewed  from  directly  above,  the  posterior  margin 
of  the  petiolar  node  is  almost  perfectly  straight,  as  opposed  to 
the  distinctly  concave  margin  of  selenophora. 

(5)  Pubescence  is  generally  sparser.  The  anterior  face  of 
the  petiolar  node  has  pubescence  only  over  its  upper  quarter, 


386  BULLETIN  :   MUSEUM  OP  COMPARATIVE  ZOOLOGY 

and  there  it  is  relatively  sparse,  whereas  in  selenophora  it  is 
abundant  over  the  entire  upper  half. 

Paratype  variation.  IIW  0.65-0.68  mm,  HL  0.75-0.80  mm, 
SL  0.57-0.60  mm,  CI  86-90,  SI  83-89,  PW  0.52-0.54  mm,  dorsal 
petiole  width  0.40-0.44  mm. 

Relationships.  P.  xenagos  is  the  largest  of  the  known  species 
of  the  selenophora  group.  Within  the  group,  it  is  most  closely 
allied  to  selenophora  itself,  as  indicated  in  the  above  comparative 
description. 

Material  examined.  N-E.  NEW  GUINEA:  Tumnang,  1500  m. 
(type  locality),  April  14-15,  1955,  holotype  and  eight  paratype 
workers  (Wilson,  ace.  no.  801)  ;  Ebabaang,  1300-1400  m.,  April 
16-18,  1955,  three  paratype  workers  (Wilson,  ace.  no.  819). 
Both  of  the  above  localities  are  in  the  Mongi  River  Watershed 
of  the  Huon  Peninsula. 

Ecological  notes.  The  Tumnang  colony  was  found  nesting 
under  the  loose  bark  of  a  rotting  stump.  The  Ebabaang  colony 
was  under  the  loose  bark  of  the  upper  surface  of  a  large  rotting 
log,  in  the  immediate  vicinity  of  a  colony  of  Amblyopone  australis 
Erichson.  Both  nest  sites  were  in  partial  clearings  at  the  side 
of  native  trails  running  through  dense  midmountain  rainforest.

INTRODUCTION 

ISome  years  ago,  while  the  author  was  doing  research  on  Ctenu- 
chidae and  other  Lepidoptera  families  at  the  Zoological  Collection 
of  the  Bavarian  State  in  Munich,  he  had  an  opportunity  to  study 


390  BULLETIN  :    MUSEUM    OP    COMPARATIVE   ZOOLOGY 

not  only  the  materials  of  that  museum  but  also  a  very  extensive 
collection  from  China  gathered  in  the  course  of  many  years  by 
the  indefatigable  investigator  of  the  Lepidoptera  of  this  country, 
Dr.  H.  Hone.  This  collection,  now  one  of  the  most  important 
components  of  the  Institute  of  Zoological  Research  and  Museum 
Alexander  Koenig  in  Bonn,  gave  the  author  a  basis  for  revision 
of  several  Chinese  Ctenuchidae  species  in  which  he  was  especially 
interested.  Further  materials  for  this  revision  were  found  in 
collections  of  the  Museum  of  Comparative  Zoology  in  Cambridge, 
the  American  Museum  of  Natural  History  in  New  York,  and  the 
U.  S.  National  Museum  in  Washington.  The  species  of  the  related 
Oriental  fauna  were  studied  from  the  collections  of  the  three 
last-mentioned  museums  and  the  State  Museum  of  Natural  His- 
tory in  Leiden.  The  necessary  knowledge  about  the  type  speci- 
mens of  Ctenuchidae  from  China,  previously  described  by  earlier 
authors,  was  received  by  the  author  from  the  British  Museum 
(Natural  History). 

The  new  genus  treated  in  this  paper  represents  a  small  group 
of  species  ranging  through  China  and  the  Oriental  Region.  These 
species  have  up  to  the  present  time  been  considered  as  belonging 
to  the  genus  Amata  F.  from  which  they  differ  both  in  the  struc- 
ture of  hind  tibiae  and  in  the  male  genitalia.  The  female  geni- 
talia could  not  be  closely  studied  because  the  preparation  of 
these  parts  involved  the  complete  destruction  of  the  markings 
of  the  abdomen  which  are  very  important  for  taxonomy  of  the 
Caeneressa  species. 

The  present  paper  may  be  considered  as  a  complete  revision 
of  the  Chinese  Caeneressa  species,  so  far  as  they  are  known. 
Concerning  some  species  ranging  also  beyond  China,  it  was  pos- 
sible to  add  information  about  their  distribution  and  geographi- 
cal variation  in  other  countries. 

The  author  wishes  to  express  his  gratitude  for  the  friendly 
cooperation  of  the  Direction  of  the  Zoological  Collection  of  the 
Bavarian  State  in  Munich  (Germany)  in  the  person  of  Prof. 
H.  Krieg  and  the  Curator  of  its  Department  of  Entomology,  Dr. 
W.  Forster,  and  thus  for  the  author's  opportunity  to  devote  most 
of  his  working-hours  to  research  work.  Hearty  thanks  also  go 
to  Dr.  H.  Hone  of  the  Institute  for  Zoological  Research  and 
Museum  Alexander  Koenig  in  Bonn  (Germany)  for  putting  his 
rich  collection  at  the  author's  disposal;  Dr.  P.  J.  Darlington,  Jr.,

sending  photographs  of  the  type  specimens  of  Caeneressa  species 
in  this  museum  and  their  genitalia,  and  for  a  great  deal  of  work 
connected  with  this  important  aid;  Mr.  S.  G.  Kiriakoff  of  the 
Zoological  Laboratories  of  the  University  of  Ghent  (Belgium) 
for  some  information  about  the  above  types ;  Mr.  F.  Daniel  of 
the  Zoological  Collection  of  the  Bavarian  State  for  his  continual 
assistance  in  the  interpretation  of  labels  in  Dr.  Hone 's  collection ; 
Mrs.  F.  Tandler  in  Arlington,  Va.,  for  her  kind  assistance  in  the 
preparation  of  the  English  text  of  the  present  paper.  The  author 
acknowledges  with  thanks  the  support  of  his  work  on  this  paper 
by  a  research  grant  (1952)  of  the  Research  Program  on  the 
U.S.S.B.  (East  European  Fund,  Inc.)  in  New  York;  this  grant 
gave  him  the  opportunity  to  study  the  materials  and  the  litera- 
ture in  the  museums  of  the  United  States.

ciliate.     Palpi    labiales   porrect,    rather    short,    roughly    scaled, 


OBRAZTSOV:    CHINESE    CAENERESSA  393 

with  a  subacute  terminal  joint.  Proboscis  moderately  long,  weak. 
Legs  smooth,  only  the  coxae  somewhat  rougher  scaled  from  the 
exterior  side ;  hind  tibiae  without  middle  spurs,  with  a  pair  of 
terminal  ones  only.   Abdomen  smoothly  scaled. 

Forewing  moderately  broad,  dilated  outward;  dorsum  nearly 
two  thirds  as  long  as  the  costa ;  termen  straight  or  slightly  convex ; 
12  veins;  Rx  to  R5  stalked;  Mi  from  upper  angle  of  the  middle 
cell;  M2  and  M3  shortly  stalked,  connate  or  slightly  separate, 
from  the  lower  angle  of  the  middle  cell;  Cuj  from  well  before 
the  angle  of  the  middle  cell ;  Cu2  from  more  or  less  behind  the 
middle  point  of  the  middle  cell ;  A2  more  or  less  arched,  extends 
to  the  tornus. 

Hindwing  subovate,  shorter  than  the  forewing  dorsum  ;  5  veins ; 
Sc  coincident  with  R  and  Mi,  to  the  costa;  M2  and  Cii!  connate 
or  shortly  stalked,  from  the  lower  angle  of  the  middle  cell ;  Cu2 
from  cell  near  three  fourths,  remote  from  Cuj  ;  A2  to  the  tornus. 

Pattern  of  the  Body  and  Wings.  In  their  pattern  the  Caener- 
essa  species  are  similar  to  most  other  Ctenuchidae  genera  of  the 
Eastern  Hemisphere.  The  predominant  scaling  of  the  head  and 
body  is  black  or  dark  brown,  often  with  a  blue,  greenish  or 
violet,  silk  or  metallic  reflection.  The  markings  are  formed  by 
white,  yellow,  orange,  or  red  scaling  on  the  dark  ground ;  some- 
times the  dark  scaling  is  completely  replaced  by  these  colored 
scales  or  pushed  into  the  background.  On  the  head  the  colorous 
markings  may  be  represented  as  a  patch  on  the  frons,  also  as 
streaks  on  the  cheeks;  exceptionally  the  dark  ground  of  the 
head  is  completely  taken  over  by  the  colorous  scaling.  On  the 
patagia  the  dark  ground  is  often  similarly  replaced,  or  they  are 
patched  with  color.  The  tegulae  are  usually  more  or  less  widely 
patched  with  color,  sometimes  without  any  black.  On  the  thorax 
colorous  markings  (streaks  and  patches)  are  often  present;  the 
pectus  usually  with  lateral  patches.  The  interior  side  of  the 
coxae  and  some  other  parts  of  the  legs  are  often  colored,  es- 
pecially in  the  males.  The  pattern  of  the  abdomen  is  formed  of 
variously  developed  transverse  segmental  bands  and  girdles,  com- 
plete or  interrupted  on  the  dorsal  or  ventral  surface;  longi- 
tudinal lines  are  also  sometimes  present.  The  scaling  of  the  body 
and  its  parts  is  never  more  than  trichromatic,  usually  it  is 
bichromatic. 


394  BULLETIN  :    MUSEUM    OF   COMPARATIVE   ZOOLOGY 

The  wing  pattern  of  Caeneressa  is  similar  to  that  of  Amata  F. 
and  formed  by  hyaline  spots  on  a  dark  ground.  In  this  way,  the 
wing  pattern  scheme  of  this  latter  genus  (cf.  Obraztsov,  1935, 
Ent.  Anz.,  15,  p.  262;  1941,  Univ.  Kijev.,  Acta  Mus.  Zool.,  1, 
(1939),  p.  114)  can  be  used  also  in  Caeneressa.  In  the  forewing 
a  triangular  spot  (m2)  is  in  the  middle  cell.  A  more  or  less  long 
spot  (nil  +  m3  °f  the  Amata  wing  pattern  scheme)  is  below 
the  middle  cell,  in  the  interspace  between  it  and  the  vein  A2 ; 
an  ovate  or  more  or  less  elongate  spot  (m4)  is  in  the  basal  part 
of  the  interspace  between  the  veins  R5  and  Mx ;  two  spots  (m5 
and  m6)  are  in  the  basal  parts  of  the  interspaces  between  the 
veins  M2  and  Chi]..  These  last  two  spots  are  separated  from  one 
another  by  the  vein  M3.  Some  smaller  extra  spots  are  often 
present ;  they  occur  near  the  basal  parts  of  the  interspaces  over 
the  vein  R5  and  below  the  vein  M1;  also  at  the  outer  angle 
formed  by  the  vein  Cu2  and  the  middle  cell.  The  subcostal  area 
is  sometimes  hyaline,  the  supradorsal  area  pale  scaled. 

In  the  hindwing  a  basal  spot  is  present.  It  occupies  the  inter- 
space between  the  middle  cell,  vein  Cu2  and  A2.  This  spot- 
usually  crosses  over  the  vein  A2  and  reaches  almost  to  the  wing 
dorsum.  Not  infrequently  it  also  crosses  over  the  lower  vein 
of  the  middle  cell  which  latter  is  in  this  case  at  least  partly 
hyaline.  The  second  hindwing  spot  is  a  distal  one.  It  occupies 
the  basal  part  of  the  interspace  between  the  veins  Cvlx  and  Cu2 
and  the  middle  cell.  This  spot  usually  crosses  over  the  vein 
Cuj  and  reaches  to  the  vein  M2.  In  case  both  spots  of  the 
hindwing  are  enlarged  and  confluent,  they  occupy  most  of  the 
surface  of  the  wing,  and  the  hindwing  becomes  hyaline  with 
dark  borders. 

Frequently  all  wing  spots  are  very  enlarged,  and  the  wings 
become  predominantly  hyaline.  In  this  instance,  the  dark  ground 
of  the  forewing  is  reduced  to  a  discal  patch  and  borders  along  the 
wing  margins.  These  borders  are  usually  dilated  at  the  wing 
apex,  often  also  between  the  veins  Cux  and  Cu2.  A  dark  ray 
along  the  vein  M2  usually  connects  the  forewing  borders  with 
the  discal  patch.  In  the  hindwing  these  borders  are  mostly 
dentate  at  the  veins  Cu!  and  Cu2.  The  veins  of  both  wings  are 
always  more  or  less  dark.

The  wing  pattern  is  bifacial  and  the  under  surface  matches  the 
upper  one.  Exceptionally  the  dark  interspaces  of  the  under 
wing  surface  are  lightened  by  yellow,  whitish  or  other  scales.

long,  at  least  moderate.  Valvae  elongate,  variously  shaped,  some- 
times slightly  asymmetrical,  in  this  instance  the  left  valva  is 
shorter;  the  upper  edge  of  the  valva  (costa)  mostly  indifferenti- 
ate ;  sacculus  more  or  less  thickened,  distally  rounded,  without 
a  free  apical  point ;  interior  side  of  the  valvae  connected  with 
the  vallum  penis  by  more  or  less  long  processus  basales.  Vallum 
penis  membranous,  only  the  fultura  inferior  sclerotized,  vari- 
ously shaped.  Aedoeagus  moderate  or  long,  more  or  less  straight 
or  slightly  curved ;  coecum  penis  moderate  or  underdeveloped ; 
vesica  with  a  cuneus  of  numerous,  little,  chitinous  spines,  or  with 
well  developed  elongate  cornuti,  sometimes  with  both. 

Female  Genitalia  (Fig.  2).  The  seventh  abdominal  segment 
with  a  broad,  strongly  sclerotized  tergite  and  a  narrow,  less 
sclerotized  sternite ;  it  forms  caudad  a  wide,  roundish  opening 
into  which  the  papillae  anales  are  retracted  in  the  position  of 
rest.  The  postsegmental  edge  of  the  seventh  sternite  with  a  wide 
indentation  displaced  to  the  left  which  borders  with  the  ostium 
bursae.  The  bottom  of  the  sinus  vaginalis  membranous,  with  a 
narrow,  arched  sclerite  cephalad  from  the  ostium  bursae,  between 
it  and  the  postsegmental  edge  of  the  seventh  sternite.  The  eighth 
segment  in  form  of  a  narrow  ring,  with  a  tergite  more  sclerotized ; 
I  he  eighth  sternite  semimembranous  and  forms  a  kind  of  medial 
ventral  plate  slightly  widened  at  the  middle.  The  narrow,  lateral 
commissurae  of  both  eighth  tergite  and  sternite  joined  into 
rather  short  apophyses  anteriores.  The  papillae  anales  soft, 
hairy,  broad  coniform,  the  apophyses  posterioi'es  nearly  three 
limes  as  long  as  the  apophyses  anteriores.  Two  short,  narrow 
papillae  genitales  between  the  papillae  anales. 

Corpus  bursae  round,  membranous,  with  a  large,  dented,  sclero- 
tized signum  dilated  cephalad  and  constricted  and  pointed 
eaudad.  Cervix  bursae  wide,  with  a  broad  lateral  appendix 
joined  to  the  ductus  seminalis.  Ductus  bursae  rather  narrower 
than  the  cervix,  constricted  and  being  stronger  near  the  wide 
ostium  bursae. 

The  above  description  of  the  female  genitalia  was  made  from 
Caeneressa  diaphana  (Koll.)  only,  and  it  is  not  safe  to  say  that 
it  may  relate  to  all  species  of  the  genus. 

Systematic  Position.  The  new  genus  Caeneressa  is  closely 
related  to  Eressa  Wkr.,  Trichaeta  Swinh.  and  Amata  F.,  and  in

the  system  has  to  be  ranked  among  this  generic  group  of  the 
Ctenuchidae.  From  Ercssa  it  differs  chiefly  in  the  veins  Mo 
and  Ciij  connate  or  stalked  on  the  hind-wing;  the  male  genitalia

of  Caeneressa  are  similar  to  those  of  the  multigutta  group  of 
Eressa.  The  new  genus  resembles  especially  Trichaeta,  but  dif- 
fers from  it  in  the  absence  of  the  lateral  hair-tufts  on  the  abdo- 
men, and  in  genitalia.  The  features  distinguishing  Caeneressa 
from  Amata  consist  of  the  absence  of  the  middle  spurs  of  the 
hind  tibiae  and  of  the  male  genitalia.  The  latter  in  Caeneressa 
do  not  have  any  developed  upper  angle  of  the  valva,  and  the 
cornuti  are  never  numerous  and  ranged  in  a  longitudinal  row, 
both  of  which  features  are  so  typical  for  Amata. 

Range.  Information  about  the  geographical  distribution  of  the 
genus  Caeneressa  is  currently  very  insufficient,  in  so  far  as  the 
systematic  position  of  many  non-Palearctic  species  ranked  under 
Amata  P.  is  not  proved.  About  the  non-Palearctic  species  of  the 
new  genus  it  is  only  known  at  present  that  albifrons  Moore,  actea 
Swinh.,  oenone  Btlr.,  era  Swinh.  and  serrata  Hmps.  belong  to 
Caeneressa.  In  the  Palearctic  region  the  genus  is  represented  by 
thirteen  species,  seven  of  them  new. 

The  range  of  the  genus  Caeneressa  is  restricted  to  China  (with 
the  north  extremity  of  distribution  reaching  the  southern  part 
of  the  province  of  Shensi),  North  India,  Burma,  Indo-China, 
Chusan,  Formosa,  and  the  Great  Sunda  Islands.  The  most  widely 
distributed  species  of  the  genus  is  diaphana  Koll.  found  in  almost 
all  parts  of  this  range,  while  the  distribution  of  other  species  is 
very  restricted.  Except  for  diaphana,  all  species  known  to  be 
from  China  are  endemics  of  this  fauna.  They  have  been  found 
in  the  provinces  of  Shensi,  Szechwan,  Kweichow,  Yunnan,  Anh- 
wei,  Hunan,  Kiangsu,  Chekiang,  Kiangsi,  Fukien,  and  Kwang- 
tung.  It  is  very  probable  that  they  may  be  present  also  in  other 
provinces  which  have  been  studied  only  to  a  very  limited  extent. 
There  is  evidence  that  rubrozonata  Pouj.  and  diaphana  Koll.  are 
the  most  widely  distributed  Caeneressa  species  in  China,  although 
it  would  be  premature  to  deny  wide  distribution  with  respect 
to  the  rest  of  the  species  of  this  genus.

no.  S.046   (M.K.). 
a,  lateral  view;  b,  ventral  view;  c,  aedoeagus. 

Range.    The  species  is  known  from  the  above  locality  only. 

Remarks.  The  appearance  of  this  new  species  is  very  like  that 
of  pratti  Leech  and  proxima,  n.  sp. ;  klapperichi  is  especially 
closely  related  to  the  first  of  these  species.  It  is  likely  that 
klapperichi  may  be  a  geographical  subspecies  of  pratti,  but 
in  view  of  our  scanty  knowledge  of  both  at  present,  it  is  better 
to  consider  them  provisionally  as  two  independent  species.  Super- 
ficially both  are  distinctive  in  the  coloring  of  the  frons  and 
patagia,  also  in  a  dissimilar  pattern  of  the  abdomen.  The  dis- 
tinguishing features  in  the  male  genitalia  are  given  in  the  pratti

TION:  "Allied  to  Syntomis  muirheadii,  Feld.,  to  which  species  it  bears 
a  strong  superficial  resemblance,  but  is  separated  therefrom  by  having 
only  two  hyaline  spots  towards  base  of  primaries,  and  blackish  margins 
to  abdominal  fold  of  secondaries.  There  is  no  yellow  patch  on  the 
posterior  edge  of  thorax,  but  one  is  situated  band-like  on  first  segment 
of  abdomen,  and  this  is  followed  by  five  yellow  belts  in  the  male  and 
four  in  female.  These  last  are  interrupted  on  the  back  of  the  female 
by  a  stripe  of  the  blackish  ground  colour.  Antennae  strongly  pectinated 
in  the  male,  a  character  which  at  once  distinguishes  it  from  male 
S.  muirheadii.  Expanse,  $  47  mm.,  $  56  mm."  (Leech,  1889). 
Zygaena  pratti  Kirby,  1892,  Synon.  Cat.  Lep.  Het.,  L  p.  95. 

Male.  Antennae  bipectinate,  black,  the  apical  half  of  the  shaft 
white.  Head  black ;  f rons  white.  Patagia  and  tegulae  yellow,  the 
latter  bordered  with  black.  Thorax  black ;  pectus  with  two  yellow 
patches  on  each  side.  Legs  concolorous  with  the  body  or  slightly 
paler ;  the  interior  side  of  the  fore  coxae  yellowish  white,  the  base 
of  the  tarsi  whitish.  Abdomen  brownish  black;  the  entire  first 
tergite  orange-yellow ;  second  segment  with  orange-yellow,  lateral 
patches  on  the  tergite  and  a  similarly  colored,  complete,  postseg- 
mental  band  on  the  sternite;  third  to  sixth  segments  (incl.)  with 
complete,  orange-yellow,  postsegmental  girdles,  paler  on  the 
ventral  surface.  Wings  brownish  black,  spots  white-hyaline. 
Length  of  the  fore  wing :  23  mm. 

In  the  forewing  a  rather  short,  wedge-shaped  spot  (m2)  at 
the  end  of  the  middle  cell;  an  elongate  spot  (m1+3)  below  it 
reaches  about  to  a  point  on  a  level  with  the  middle  of  the  middle 
cell  spot;  a  rather  narrow,  elongate  spot  (m4)  between  the 
veins  R5  and  Mx  accompanied  by  two  short,  hyaline  streaks 
above  and  beneath;  two  shorter  but  broader,  egg-shaped  spots 
(m5  and  m6)  between  the  veins  M2  and   Cui  separated  from 


406  BULLETIN  :    MUSEUM    OF    COMPARATIVE    ZOOLOGY 

each  other  by  the  black  vein  M3  ;  the  upper  of  these  spots  is 
slightly  longer  than  the  lower   one. 

The  hindwing  with  a  large  basal  spot  which  begins  in  the 
middle  cell  and  extends  almost  to  the  dorsum;  a  smaller  distal 
spot  separated  from  the  basal  spot  by  a  transverse  black  bar  and 
divided  by  the  black  vein  Cut  into  two  unequal  parts. 

Female.  Similar  to  the  male.  Antennae  serrate.  Frons  greyish 
white.  Patagia  black,  yellowish  at  sides.  First  tergite  of  the 
abdomen  orange-yellow,  second  to  fifth  tergites  (incl.)  with 
similarly  colored,  broad  lateral  patches;  the  corresponding  ster- 
nites  with  paler  yellow  postsegmental  bands.  The  subcostal 
area  of  the  forewing  whitish  hyaline.  Length  of  the  forewing: 
26-28  mm. 

Male  Genitalia  (PI.  1,  fig.  6).  Like  those  of  klapperichi,  n.  sp., 
but  the  valvae  tips  strongly  curved  inward.  Fultura  inferior  more 
elongate.  The  distal  cornutus  narrower  but  more  dilated  at  the 
base ;  the  proximal  cornutus  slightly  longer  than  in  klapperichi. 

Types.  Holotype,  male,  and  allotype,  female,  Kiukiang,  Prov- 
ince Kiangsi,  June,  1887  A.  E.  Pratt  (genitalia  preparation  of 
the  holotype  no.  221;  B.M.). 

Additional  material  examined.  One  female.  Province  Kiangsi, 
June  15  (A.M.N.H.). 

Range.    Chinese  province  of  Kiangsi. 

Remarks.  Very  similar  to  both  preceding  species  whose  dis- 
tinguishing features  are  discussed  above.  The  resemblance  of 
pratti  to  diaphana  Koll.  ssp.  muirheadii  Fldr.  with  which  this 
species  has  been  compared  by  Leech  (1889)  is  very  remote  and 
neither  can  be  mistaken  for  the  other.  The  hyaline  wing  spots 
in  muirheadii  occupy  a  larger  surface,  the  supplementary  ele- 
ments of  the  markings  are  more  developed,  the  abdominal 
girdles  more  numerous.  In  addition  to  these  differences  and 
those  in  the  male  genitalia,  the  antennae  of  muirheadii  are  serrate 
in  the  male  and  simple  in  the  female.

Male.  Antennae  bipectinate,  black,  one-fourth  white-tipped. 
Head  and  patagia  entirely  black ;  tegulae  yellow  with  black  end- 
hairs.  Thorax  black  with  a  large,  yellow,  posterior  patch ;  pectus 
with  a  faint-yellow  patch  on  each  side.  Legs  black,  the  interior 
surface  of  the  coxae  yellow.  Abdomen  violet-black;  first  tergite 
yellow,  at  the  middle  broadly  interrupted  by  black ;  yellow,  post- 
segmental  bands  on  second  to  seventh  segments  (incl.),  enlarged 
medio-dorsally  and  ventro-laterally,  sometimes  absent  on  fifth 
and  sixth  sternites.  Wings  black,  spots  white-hyaline.  Length  of 
the  forewing:  17-19  mm. 

In  the  forewing  a  long,  wedge-shaped  spot  (m2)  in  the  middle 
cell;  below  it  a  long,  more  or  less  broad,  slightly  arched  spot 
(nijls)  which  extends  from  near  the  wing  base  to  about  three- 
fourths  of  the  dorsum;  an  elongate-ovate  spot  (m4)  above  the 
base  of  the  vein  M1;  accompanied  by  a  small,  slightly  elongate 
extra  spot  below  this  vein,  and  sometimes  also  by  a  little  dot 
above  the  base  of  the  vein  R5  ;  two  spots  (m5  and  m6)  in  the 
interspaces  of  the  veins  M2  and  Culs  egg-shaped,  dilated  toward 
outside,  the  lower  of  them  slightly  broader  and  longer,  separated 
from  each  other  by  the  black  vein  M3  ;  sometimes  a  little,  ovate, 
extra  spot  above  the  base  of  the  vein  Cu2 . 

The  hindwing  spots  form  a  common  hyaline  area  bordered  by 
black ;  these  borders  are  broad  at  the  costa,  dilated  at  the  apex, 
with  an  obtuse  tooth  at  the  vein  A2. 

Female.  Similar  to  the  male  but  with  antennae  serrate.  The 
eyes  circumciliated  with  yellow.  The  interior  surface  of  the 
coxae  black.  First  abdominal  tergite  with  two  yellow,  lateral 
patches  and  a  similarly  colored  streak  at  the  middle ;  second  to 
sixth  segments  (incl.)  with  yellow  bands  dilated  medio-dorsally 
and  ventro-laterally,  the  two  posterior  ones  sometimes  reduced 
or  absent. 

Male  Genitalia  (Fig.  5).  Tegumen  moderately  arched;  uncus 
long,  undulate,  with  a  short  tip  curved  downward;  saccus  long, 
narrow.  Valvae  symmetrical;  sacculus  large,  thickened,  with  a 
round  tip ;  upper  edge  of  the  valva  almost  straight ;  an  acute

projection  between  it  and  the  irregularly  concave  distal  edge; 
valva  tip  truncate,  with  a  prolonged,  acute,  distal  angle ;  proces- 
sus basales  extend  to  the  vallum  penis,  their  tips  dilated.  Fultura

Additional  material  examined.  Two  males  and  four  females, 
Kuatun,  Province  Fukien,  2300  m.alt.,  May  19  till  June  11,  1938, 
J.  Klapperich  (M.K.) ;  one  male  and  one  female,  the  same  data 
(preparation  of  the  male  genitalia  no.  S.049 ;  Z.C.M.). 

Range.  Chinese  provinces  of  Chekiang  and  Fukien ;  Chusan 
Islands. 

Variation.  The  nominate  form  of  the  species  was  described 
as  having  a  single  extra-spot  below  the  f orewing  spot  m4 .  Most  of 
the  specimens  examined  from  Kuatun  are  like  the  type,  others 
have  extra  spots  above  and  beneath  the  spot  m4.  Sometimes 
another  extra  spot,  on  the  outer  side  of  the  f orewing  spot  mu3 
is  present.  A  male  specimen  from  Kuatun  (May  20,  1938)  lacks 
extra  spots  completely. 

Remarks.  This  species  was  established  by  Leech  as  an  aberra- 
tion of  sivinhoei  Leech  and  considered  by  later  authors  as  belong- 
ing to  actea  Swinh.  but  it  has  nothing  to  do  with  either  of  these 
species.  It  bears  rather  some  likeness  to  proxima,  n.  sp.,  but  is 
much  smaller  and  with  no  spot  on  the  frons,  has  dissimilar 
markings  of  the  abdomen  and  very  distinct  genitalia.

pectus  with  yellow,  lateral  patches.  Abdomen  black ;  first  tergite 
with  yellow  lateral  patches;  second  to  seventh  segments  (incl.) 
with  yellow  postsegmental  bands.  Wings  hyaline  with  veins  and 
borders  black,  the  latter  enlarged  at  the  apex.  Forewing,  more- 
over, with  a  black,  subquadrate  discal  spot  and  a  black  ray 
along  the  vein  M2  from  the  discal  spot  to  the  black  wing  borders ; 
these  latter  with  a  truncate  tooth  between  the  veins  Cuj  and 
Cu2  ;  subcostal  and  supradorsal  areas  black.  Hindwing  with 
the  subcostal  area  and  the  middle  cell  black.  Length  of  the  fore- 
wing  :  16  mm. 

Female.  Similar  to  the  male  but  antennae  serrate,  black,  white 
tipped.  Abdomen  with  the  first  tergite  patched  not  only  laterally 
but  also  with  presegmental  and  postsegmental  3rellow  patches  at 
the  middle;  all  yellow  abdominal  bands  dilated  at  the  middle; 
seventh  segment  without  any  band.  Length  of  the  forewing: 
17  mm. 

Male  Genitalia  (PI.  2,  fig.  6).  Like  those  of  hocnei  (cf.  below), 
but  differing  from  them  as  follows :  Tegumen  broader ;  uncus 
with  a  more  curved  tip.  Both  valvae  almost  equally  long ;  the 
lower  distal  angle  of  the  left  valva  stout,  the  upper  angle  directed 
more  upward ;  in  the  right  valva  the  upper  distal  angle  more 
acute. 

Types.  Holotype,  male,  Mupin,  Province  Szechwan,  June, 
Kricheldorff  (preparation  of  genitalia  no.  223;  B.M.)  ;  allotype, 
female,  Chiatingfu,  Province  Szechwan,  July,  A.  E.  Pratt  (B.M.). 

Range.   Chinese  province  Szechwan. 

Remarks.  The  acquaintance  of  the  author  with  this  species 
is  based  on  photographs  of  the  type  specimens  in  the  British 
Museum  and  the  male  genitalia  of  the  holotype ;  certain  charac- 
ters of  the  markings  of  those  specimens  were  verified  by  Mr. 
S.  G.  Kiriakoff  at  the  author's  request. 

This  species  was  considered  by  Hampson  (1898)  as  a  sub- 
species of  actea  Swinh.,  while  in  point  of  fact  swinhoei  differs 
from  Caeneressa  actea  (Swinh.)  (PI.  2,  figs.  1-3)  both  super- 
ficially and  in  the  male  genitalia.  The  frons  of  actea  is  yellow 
in  the  female ;  the  eighth  abdominal  segment  of  the  male  (seventh 
of  the  female)  is  yellow;  in  swinhoei  it  is  black.  The  male  geni- 
talia of  actea  are  very  typical :  uncus  deeply  undulate,  gibbous 
before  a  rather  narrow  and  long  tip;  saccus  rather  short;  the 
right  valva  with  the  lower  distal  angle  pointed  and  the  upper 


OBRAZTSOV:    CHINESE    CAENERESSA  411 

angle  broadly  rounded,  underdeveloped;  the  left  valva  much 
narrowed  distally,  with  an  almost  straight,  sharply  pointed  lower 
distal  angle.  Aedoeagus  of  actea  is  shorter  and  thicker  than  in 
swinhoei. 

For  a  discussion  of  distinguishing  features  of  very  similar 
hoenei,  dispar  and  zernyi,  refer  below  to  the  descriptions  of  these 
species.

white.  Head  black ;  f rons  yellow.  Patagia  black ;  tegulae  yellow 
with  black  end-hairs.  Thorax  black  with  a  posterior  yellow  patch  ; 
pectus  with  two  yellow  patches  on  each  side.  Legs  concolorous 
with  the  body;  the  interior  side  of  the  coxae  entirely  yellow. 
Abdomen  black ;  first  tergite  with  lateral  yellow  patches ;  yellow 
postsegmental  bands  (dilated  on  the  ventral  side)  on  the  follow- 
ing six  segments ;  the  tip  of  the  abdomen  black  with  bluish-violet 
gloss. 

Wings  hyaline  with  black  veins  and  narrow  (at  the  apex 
dilated)  black  borders.  In  the  forewing  a  black,  subrectangular 
discal  patch ;  the  vein  M2  connecting  this  patch  with  the  wing 
border  black  scaled ;  a  broad,  truncate  tooth  on  the  interior  side 
of  the  black  wing  border  between  the  veins  Cu!  and  Cu2  ;  sub- 
costal and  supradorsal  areas  of  the  forewing  black.  Hindwing 
with  very  narrow  black  borders  slightly  dilated  at  the  apex. 
Reverse  of  both  wings  with  a  strong  yellowish  scaling  along  the 
costa  and  the  dorsum,  on  interior  edges  of  the  black  wing  borders, 
partly  also  along  the  veins.  Length  of  the  forewing  :  15-19  mm. 

Female.  Similar  to  the  male.  Antennae  serrate.  Head  en- 
tirely black.  Coxae  of  all  legs  yellow  streaked.  Yellow  bands, 
narrower  on  the  ventral  side,  on  second  to  sixth  abdominal  seg- 
ments (incl.). 

Male  Genitalia  ( Fig.  6 ) .  Tegumen  elongate,  moderately  arched ; 
uncus  long,  equally  curved;  saccus  long  and  rather  narrow. 
Valvae  asymmetrical,  the  right  one  longer;  upper  and  distal 
edges  not  differentiated  from  one  another;  the  distal  part  of 
the    valva   subrectangular,   with   a   truncate-concave   edge   and

upper  and  lower  angles  both  acute  and  longer  on  the  right  valva ; 
sacculus  long  and  wide ;  processus  basales  narrow,  dilated  at 
tips.  Vallum  penis  with  two  lateral  dentate  plates  joined  to  the 
tips  of  processus  basales.  Fultura  inferior  rounded,  inversely 
heart-shaped.  Aedoeagus  slender  and  very  long,  slightly  curved 
downward  at  the  coecum  penis  and  upward  at  the  tip ;  a  single, 
thorn-shaped  cornutus. 

Types.  Holotype,  male,  Tapaishan  in  Tsinling,  Province  Shensi,

Remarks.  From  swinhoei  Leech  to  which  the  new  species  is 
closely  related,  it  differs  in  having  black  patagia  and  a  yellow 
irons  in  the  male.  C.  hoenei  also  resembles  actea  Swinh.,  dispar 
n.  sp.  and  zernyi  n.  sp.  but  in  actea  the  frons  is  black  in  the 
male,  yellow  in  the  female,  and  the  patagia  and  the  anal  abdom- 
inal segments  are  yellow.  Both  sexes  of  dispar  have  entirely  yel- 
low head  and  patagia,  and  the  yellow  abdominal  bands  are  almost

joined  together;  zernyi,  in  which  the  female  is  unknown,  has  an 
entirely  black  head.  The  genitalia  of  all  these  species  are  unlike 
those  of  hoenei.

PI.  4,  figs.  1,  2 

Male.  Antennae  bipectinate,  dark  brown,  the  two  apical  thirds 
of  their  shafts  yellowish.  Head,  patagia,  and  tegulae  yellow. 
Thorax  brownish  black  with  a  posterior  yellow  patch ;  pectus  with 
two  yellow  patches  on  each  side.  Legs  brownish,  diffusely  yellow 
scaled.  Abdomen  black ;  first  tergite  with  a  yellow  rectangle, 
black  patched  in  the  middle ;  second  to  seventh  segments  ( incl. ) 
with  postsegmental  yellow  bands  joined  at  the  middle  line,  each 
of  the  tergites  consequently  with  two  dorsolateral  black  patches ; 
eighth  tergite  black  postsegmentally  with  yellow  hairs;  sternites 
whose  scaling  is  very  damaged  may  presumably  be  entirely  yel- 
low. 

Wings  hyaline,  veins  and  narrow  borders  (dilated  at  the  apex) 
brownish  black.  Forewing,  moreover,  with  a  brownish-black 
discal  patch;  vein  M2  rather  more  blackish  scaled,  supradorsal 
area  black ;  subcostal  area  with  longitudinal  hyaline  streak.  Costa 
of  the  hindwing  broad  black ;  upper  part  of  the  middle  cell 
hyaline.   Length  of  the  forewing :  16  mm. 

Female.  Similar  to  the  male  from  which  it  differs  as  follows : 
Antennae  serrate,  with  short,  yellowish-white  tips.  Head  black; 
frons,  cheeks  and  vertex  diffusely  yellow  scaled.  Legs  black. 
Abdomen  with  bands  as  in  the  male  but  on  first  to  sixth  tergites 
(incl.)  only;  the  joining  of  bands  not  so  clear;  anal  segments 
and  all  sternites  black.  The  black  pigmentation  of  the  body 
more  intensive  and  the  yellow  markings  more  orange.  Black 
markings  more  dilated  in  both  wings,  and  the  black  forewing 
borders  with  a  distinct,  broad  tooth  at  the  vein  Cu2.  Length  of 
the  forewing :  18-19   mm. 

Male  Genitalia  (Fig.  7).  Tegumen  with  two  lateral  appendages 
curved  upward;  uncus  rather  long,  moderately  curved;  saccus 
rather  long.  Valvae  short,  almost  symmetrical ;  sacculus  narrow ; 
the  terminal  part  of  the  valva  much  narrower  than  the  basal 
part;  the  upper  distal  angle  slightly  acute;  processus   basales

straight,  extending  to  the  vallum  penis.  Fultura  inferior  elongate- 
ovate,  with  a  concave  upper  edge.  Aedoeagus  comparatively 
large,  slightly   curved ;  three  thorn-like  cornuti. 

Types.  Holotype,  male,  Kuatun  (27°40'  N.  and  117 °40'  E.), 
Province  Fukien,  2300  m.  alt.,  May  19,  1938,  J.  Klapperich  (geni- 
talia preparation  no.  S.048;  M.K.)  ;  allotype,  female,  the  same 
locality,  May  6,  1938,  J.  Klapperich  (M.K.)  ;  paratype,  female,

Additional  material  examined.  Female,  Shanghai,  Province 
Chekiang,  H.  Hone  (M.K.). 

Range.  Chinese  provinces  Fukien  and  Chekiang. 

Remarks.  The  similarity  of  both  sexes  in  certain  characters  and 
the  fact  that  the  moths  were  found  in  the  same  locality  within  a 
comparatively  short  time  period,  argues  in  favor  of  considering 
them  conspecific.  If  this  is  not  the  case,  the  female  may  be  con- 
sidered as  a  new  species  because  it  is  unlike  any  other  known 
species. 

The  female  specimen  from  Shanghai  has  an  abdominal  pattern 
like  that    in  the  male  holotype;  in  the  rest  of  its  characters  it 


OBRAZTSOV:    CHINESE    CAENERESSA  415 

does  not  differ  from  the  Kuatun  females  except  that  the  black 
wing  markings  are  rather  more  developed  and  some  of  the  hyaline 
areas  are  more  spot-like. 

Some  similarity  exists  between  dispar  and  actea  Swinh.,  swin- 
hoei  Leech,  and  zernyi  n.  sp.,  but  all  these  species  have  their 
abdominal  bands  free,  not  joined.  The  male  genitalia  and  some 
other  characters  in  the  above  species  are  unlike  those  of  dispar. 
The  male  of  dispar  recalls  slightly  the  Formosan  Amata  kara- 
pinensis  (Strd.)  but  the  latter  is  not  a  Caeneressa  species. 

8.    Caeneressa  zernyi,  new  species 
PL  4,  fig.  3 

Male.  Antennae  bipectinate,  black,  the  apical  third  of  their 
shafts  white.  Head,  patagia,  and  thorax  black;  tegulae  yellow 
with  black  end-hairs.  Legs  brown.  Abdomen  black  with  the  first 
tergite  orange  patched  (the  scaling  of  the  remaining  abdominal 
segments  is  damaged,  and  only  some  orange  scales  indicate  thai 
bands  were  originally  present ) . 

Wings  hyaline  with  veins  and  borders  black.  Forewing  with 
a  subquadrate,  black  discal  patch ;  a  black  ray  along  the  vein 
M2  joins  the  discal  patch  with  the  dilated  apical  border;  a 
truncate  interior  tooth  of  the  black  wing  border  between  the 
veins  Cuj  and  Clio  ;  subcostal  and  supradorsal  areas  black.  Hind- 
wing  with  black  borders  dilated  at  the  apex;  costa  and  the  middle 
cell  black.    Length  of  the  forewing:  16  mm. 

Male  Genitalia  (Fig.  8).  Tegumen  scarcely  developed;  uncus 
very  long,  curved,  dilated  at  the  base  and  before  the  narrow, 
rounded  tip;  (the  saecus  is  missing).  Valvae  symmetrical;  sac- 
culus  well  developed,  broad,  rather  Hat ;  the  upper  edge  of  the 
valva  almost  straight  to  the  distal  angle ;  the  apical  part  of  the 
valva  narrow  and  elongate ;  processus  basales  much  longer  than 
the  vallum  penis,  curved,  arranged  caudad.  Fultura  inferior 
irregularly  shaped,  narrow  in  the  upper  part  and  dilated  in  the 
lower.  Aedoeagus  slender,  moderately  long,  slightly  curved,  with 
a  moderate  coecum  penis;  a  single,  thorn-shaped  cornutus. 

Type.  Monotype,  male,  Shinchow  near  Canton,  Province 
Ivwangtung  (genitalia  preparation  no.  S.008;  Z.C.M.).

as  new  but  was  not  described.  It  is  superficially  similar  to  actea 
Swinh.,  swinhoei  Leech  and  dispar  n.  sp.  but'  differs  from  them 
in  the  black  patagia.  From  hoenei  n.  sp.  it  differs  in  having  an 
entirely  black  head.  The  peculiar  processus  basales  and  the 
uncus  of  zernyi  are  unlike  those  of  the  remaining  known  Caener- 
essa species.

Female.  Antennae  deeply  serrate,  black,  one-fourth  white 
tipped.  Head  red ;  a  narrow  streak  between  the  eyes  and  the 
mouth    parts,   black.     Patagia    entirely    red ;    tegulae    red   with 


OBRAZTSOV  :    CHINESE   CAENERESSA  417 

brownish-black  end-hairs.  Thorax  black  with  a  posterior  red 
patch ;  pectus  with  two  red  patches  on  each  side.  Legs  entirely 
black.  Abdomen  black  with  six  broad,  red,  postsegmental  bands 
on  first  to  sixth  tergites  (incl.). 

Wings  hyaline  with  black  veins  and  borders.  Forewing  with 
the  borders  broadly  dilated  at  apex  and  forming  a  broad,  in- 
terior tooth  at  the  vein  Cu2  ;  a  broad,  black  discal  spot  sending  a 
ray  along  the  vein  M2  to  the  border;  subcostal  and  supradorsal 
areas  rather  diffusely  black  scaled.  Hindwing  borders  narrow, 
dilated  only  at  the  apex ;  costa  and  the  greatest  part  of  the  middle 
cell  black.   Length  of  the  forewing  15  mm. 

Type.  Monotype,  female,  mountains  near  Ningyuenfu,  Prov- 
ince Szechwan  (Z.C.M.). 

Remarks.  Because  of  its  red  pigmentation,  ningyuena  may 
be  compared  with  rubrozonata  Pouj.  to  which  it  has  no  other 
similarity.  The  female  of  rubrozonata  has  simple  antennae ;  only 
its  frons,  not  the  whole  head,  is  red ;  the  red  pigmentation  on 
the  tegulae  and  the  pectus  is  less  developed,  the  thorax  is  en- 
tirely black.  Also  the  postsegmental  edge  of  the  seventh  abdom- 
inal sternite  is  distinct  in  both  species  (Pig.  12).  From  graduata 
Hmps.,  also  red-pigmented,  ningyuena  can  be  distinguished  by 
its  broader  forewing  shape,  less  developed  black  wing  markings, 
and  absence  of  the  longitudinal  red  lines  on  the  abdomen.  The 
antennae  of  graduata  are  simple  in  the  female.

Antennae  shortly  bipeetinate  in  the  male,  serrate  in  the  female. 
In  other  respects,  this  species  cannot  be  distinguished  from  C. 
diaphana   (Koll.). 

Male  Genitalia.  Uncus  rather  longer  than  in  diaphana,  with 
a  more  prolonged  and  acute  tip ;  saccus  larger ;  valvae  somewhat 
broader.  Fultura  inferior  almost  regular  ovate. 

Type.  Holotype,  male,  North  India  (B.M.). 

Additional  material  examined.  Five  males  and  five  females, 
Kooloo,  Himalaya,  Carleton  (preparation  of  male  genitalia  no. 
1,  Obr.;  M.C.Z.). 

Range.  Western  Himalaya. 

Remarks.  Although  this  species  has  been  not  found  within 
the  limits  of  China,  its  presence  in  the  Western  Himalaya  and 
a  great  similarity  to  diaphana  Koll.  are  reasons  for  including  it 
in  the  present  revision.  Walker  (1854)  described  the  antennae 
of  oenone  as  "serrated  along  the  whole  length."  This  is  an 
evidence  that  he  correctly  distinguished  between  oenone  and 
diaphana.  The  later  authors  neglected  this  feature  and  ranked 
in  none  to  diaphana.  As  matter  of  fact,  the  antennae  of  oenone 
are  shortly  bipeetinate  in  the  male,  but  without  a  good  magnifier 
seem  serrate ;  those  of  diaphana  seem,  under  the  same  conditions, 
simple,  and  Hampson  (1898)  therefore  placed  this  moth  among 
the  species  with  antennae  simple  in  both  sexes. 

The  series  of  the  oenone  moths  examined  at  the  Museum  of 
Comparative  Zoology,  represent  specimens  with  markings  like 
those  of  the  nominotypical  subspecies  of  diaphana.  It  is  very 
significant  that  one  diaphana  female  specimen  was  also  caught 
in  Kooloo.

above.  Head  black;  frons  and  narrow  streaks  behind  the  eyes 
white,  cream-white,  yellow  or  orange.  The  ground  of  the  whole 
body  black,  often  with  a  greenish,  violet,  or  bronze  reflection. 
Patagia  from  cream-whitish  to  orange,  in  the  middle  usually 
divided  by  black;  tegulae  concolorous  with  the  patagia,  wTith 
black  end-hairs.  Thorax  with  a  broad  transversal,  whitish,  yellow 
or  orange,  posterior  patch ;  this  patch  is  often  divided  into  two 
patches ;  the  middle  part  of  the  thorax  sometimes  with  two  longi- 
tudinal, concolorous  lateral  streaks ;  pectus  with  twTo  similar 
patches  on  each  side.  Legs  black  or  dark  brown,  often  with  a 
bronze  or  greenish  reflection;  sometimes  the  femora  and  tibiae 
with  whitish  or  yellow  longitudinal  streaks,  and  the  inner 
surface  of  the  coxae  is  of  the  same  color;  first  joint  of  the  tarsi 
sometimes  whitish.  Abdomen  with  whitish,  yellow  or  orange 
bands  on  seven  segments;  at  least  some  of  these  bands  dorsally 
narrowed  or  interrupted  at  the  middle;  some  of  the  anterior 
bands  often  paler  than  the  remaining  bands ;  on  the  ventral  side 
the  bands  are  usually  somewhat  paler;  the  anal  segment  black 
or  yellow. 

Wings  predominantly  hyaline  with  black  veins  and  borders.  In 
the  forewing  these  borders  are  always  dilated  at  the  apex,  usually 
more  or  less  dilated  at  the  vein  M2  and  between  the  veins  Cuj 
and  Cu2  ;  discocellulars  with  a  more  or  less  broad,  black  spot ; 
along  the  vein  M2  usually  a  black  ray  joining  the  discal  spot 
with  the  wing  borders.  All  these  black  markings  are  variously 
developed,  and  the  hyaline  area  is  sometimes  reduced  to  separate 
spots:  a  long  spot  (m1+3)  below  the  middle  cell  extends  nearly 
from  the  wing  base  to  the  tornus;  a  wedge-shaped  spot  (m2) 
in  the  middle  cell ;  a  more  or  less  large  extra  spot  above  the  base 
of  the  vein  Cu2  ;  three  larger,  elongate  spots  (m4  to  m6),  between 
the  veins  R5  and  Mt  and  M3  and  Cux  form  (together  with  two 
smaller  and  narrower  extra  spots  above  and  beneath  the  spot 
m4)  an  exterior  row  of  forewing  spots.  The  basal  parts  of  the 
forewing  veins  often  yellow.  In  the  hindwing  the  black  borders 
dilated  at  the  apex  and  slightly  indented  at  the  vein  Cu2  ;  the 
middle  cell  locked  by  a  black  discal  spot.  A  stronger  development 
of  the  black  markings  may  make  two  spots  of  the  whole  hyaline 
area  of  the  hindwing ;  they  are  almost  separated  from  each  other  by 
the  vein  Cu2.  Middle  cell  and  dorsum  of  the  hindwing  often 
whitish  or  yellowish  scaled.  Length  of  the  forewing :  15-25  mm.

Female.  Similar  to  the  male.  Antennae  simple.  Abdomen  with 
six  whitish  or  orange  bands.   Length  of  the  f orewing :  17-30  mm. 

Male  Genitalia  (Pig.  1).  Tegumen  elongate,  arched;  uncus 
long,  curved,  dilated  toward  the  tip  and  then  pointed;  in  the

rounded.  Aedoeagus  moderately  thickened,  slightly  curved  at  the 
middle;  coecum  penis  moderate,  broadly  rounded;  cuneus  com- 
posed of  numerous,  diffusely  arranged,  small,  sclerotized  cones

Remarks.  In  the  limits  of  its  range,  this  species  is  found  in 
three  subspecies.  They  have  no  difference  in  the  genitalia  and 
are  linked  together  by  intermediate  forms.

Wings  mostly  hyaline  with  the  black  only  on  their  borders, 
discocellulars,  and  other  veins.  The  hyaline  areas  separated  by 
veins  and  merely  by  a  black  ray  along  the  forewing  vein  Mo. 
The  interior  tooth  of  the  forewing  terminal  border  between  the 
veins  C\i1  and  C112  never  meets  the  middle-sized  discocellular 
patch  and  just  along  these  veins  reaches  sometimes  to  the  middle 
cell.  Patagia  yellow ;  thorax  with  or  without  longitudinal  yellow 
streaks;  yellow  abdominal  bauds  interrupted  at  the  middle,  at 
least  on  two  basal  tergites.

Variation.  The  chief  characters  of  the  subspecies  are  more  or 
less  stable  except  for  the  width  of  the  black  wing  borders  and  the 
yellow  body  pigmentation  which  may  vary  from  specimen  to 
specimen.  All  intermediate  forms  between  the  more  yellow  pig- 
mented baiaea  and  the  less  yellow  pigmented  diaphana  were 
found,  and  there  is  no  necessity  to  separate  these  forms  under 
special  names.  The  same  should  be  said  of  horishana  and  hoppo 
which  are  only  synonyms  for  diaphana.  The  extreme  individual 
forms  are  the  following  two.

Remarks.  There  is  no  doubt  that  diaphana  and  baiaea  are 
conspecific.  The  author  had  at  his  disposal  both  these  forms  and 
could  not  find  any  constant  features  which  would  distinguish  one 
form  from  the  other.  The  specimens  like  horishana  and  hoppo 
were  found  among  the  populations  of  ssp.  diaphana  from  the 
continental  part  of  China,  and  Kawada  (1934,  loc.  cit.)  was  right 
in  considering  both  Formosan  "species"  as  forms  of  diaphana, 
which  he  erroneously  called  muirheadi.  The  ab.  melas  was  found 
in  almost  all  parts  of  the  ssp.  diaphana  range;  similar  female 
specimens  with   the   yellow   abdominal   markings   replaced   by

white,  the  author  studied  from  Ningyuenfu,  Morendro  Doouai 
and  Chiengmai,  also  from  Java.  In  the  literature  melas  was 
mentioned  also  from  Himalaya,  Nepal  (type),  Sikkhim,  Burma, 
and  Indochina.  This  form  like  ab.  andersoni  has  no  geographical 
adaptation.  A  separation  of  flavolavata  from  this  latter  form 
was  unreasonable:  Rothschild  (1910)  was  wrong  in  describing 
the  last  abdominal  segment  of  andersoni  female  as  blue  black. 
The  remaining  characters  of  flavolavata  and  andersoni,  the 
yellow  tinge  of  the  hyaline  wing  membrane  included,  are  com- 
mon and  may  be  observed  in  any  population  of  ssp.  diqphana.

Variation.  This  subspecies  varies  chiefly  in  size.  The  wing 
pattern  is  more  or  less  constant;  only  the  varied  shape  and  size 
of  the  forewing  extra  spot  above  the  vein  Cu2  affects  the  width 
of  the  black  wing  border.  The  yellow  abdominal  girdles  are 
mostly  well  developed;  only  in  one  female  from  Chungking  is 
there  no  girdle  on  the  second  tergite. 

Remarks.  Hampson  (1898)  and  some  other  authors  ranked 
Syntomis  ancta  Leech  (The  Entom.,  31,  1898,  p.  153)  to  muir- 
headii,  but  by  mistake.  The  present  author  had  an  opportunity 
to  study  the  male  genitalia  of  the  type  of  aucta  on  the  basis  of 
a  photograph  received  from  the  British  Museum.   This  examina-

the  genus  Amata  F.

PI.  3,  figs.  10,  11 

From  the  preceding  subspecies  this  differs  by  a  slight  develop- 
ment of  the  yellow  pigmentation  of  the  patagia  and  thorax. 
Patagia  black  with  some  yellowish  scales  at  the  anterior  edge ; 
longitudinal  yellow  streaks  of  the  thorax  obsolescent. 

Types.  Holotype,  male  (May  30),  allotype,  female  (June  6), 
and  two  paratypes  (M.K.)  ;  two  further  paratypes,  one  male 
and  one  female  (Z.C.M.).  The  series  originates  from  Hoeng- 
shan,  Province  Hunan,  900  m.  alt.,  May  28  till  June  6,  September 
4,  1933,  H.  Hone. 

Range.    Known  from  the  above  locality  only. 

Remarks.  Although  the  distinction  between  the  new  sub- 
species and  ssp.  muirheadii  seems  minimal,  it  is  constant  in  all 
the  specimens  examined  from  Hoengshan.  On  the  other  hand, 
not  any  specimen  of  muirheadii,  of  the  large  series  examined,  has 
the  yellow  of  the  patagia  so  much  reduced  as  in  hunanensis. 
This  fact  gives  the  ground  for  considering  the  Hunan  specimens 
a  separate  geographical  form.

with  white,  hyaline  spots.   Length  of  the  forewing:  11-16  mm. 

Forewing  with  five  ground  spots :  an  elongate-cuneiform  spot 
(m2)  in  the  middle  cell,  usually  as  broad  as  this  latter;  a  long 
spot  (m1+3)  below  it,  reaching  from  the  wing  base  almost  to  the 
tornus,  or  the  basal  part  of  this  spot  (mj)  absent;  a  spot  (m4) 
in  the  area  between  the  veins  R5  and  Mx  mostly  shorter  than  that 
(m6)  between  the  veins  M3  and  Cuj  ;  a  spot  (m5)  between  the 
veins  Mo  and  M3  often  the  smallest  in  the  exterior  spots  series ; 
sometimes  more  or  less  developed  extra  spots  above  the  vein 
Cu2  and  at  both  sides  of  the  spot  m4.  Hindwing  with  a  more 
or  less  large  spot  placed  right  at  the  dorsum  and  separated  from 
it  by  a  narrow  black  border ;  occasionally  this  spot  reaches 
across  the  vein  Cui. 

Female.  Similar  to  the  male.  Antennae  simple.  Frons  red- 
dish, yellowish,  grey  or  black.  Legs  entirely  black.  Girdle  on 
the  seventh  tergite  always  absent.

Remarks.  Hampson  (1898)  wrote  on  this  species  :  "both  wings 
with  veins  4  and  5  shortly  stalked."  As  a  matter  of  fact,  this 
character  is  inconstant,  and  the  two  veins  mentioned  are  often

specimens  (one  from  Mokanshan  and  five  from  Kuatun)  the 
patagia  are  entirely  red.  Sometimes  there  are  no  girdles  on  the 
ventral  surface  (two  females  from  Mokanshan,  three  males  and 
nine  females  from  Kuatun).  Most  of  the  specimens  have  extra 
spots  in  the  forewings;  they  are  absent  in  only  four  specimens 
(one  male  and  three  females  from  Mokanshan).

INTRODUCTION 


Adult  Hymenoptera  are  distinctly  discontinuous  in  their 
feeding  habits,  and  subsist  very  largely  on  fluids  (Bischoff  '27). 
The  relatively  large  amount  of  liquid  nutrient  gathered  during 
one  of  the  intensive  feeding  periods  is  not  passed  directly  into 
the  midgut  (text  fig.  1,  m.  g.),  but  is  first  temporarily  retained 
within  a  sac-like  dilation  of  the  stomodaeum  called  the  crop 
(text  fig.  1,  cr.).  At  intervals,  controlled  amounts  of  liquid  are 
released  from  the  crop  to  the  midgut.  Since  in  this  way  food 
is  passed  gradually  into  the  midgut,  thereby  avoiding  a  sudden 
dilution  of  midgut  enzymes  at  feeding,  the  digestive  and  ab- 
sorptive processes  within  the  midgut  proceed  at  optimal  effic- 
iency. The  organ  that  regulates  the  delivery  of  fluid  from  crop 
to  midgut  is  the  proventriculus  (text  fig.  1,  pv.).  In  adult 
Hymenoptera  the  proventriculus,  as  usually  developed,  is  no 
mere  strait  between  crop  and  midgut.  It  consists  of  a  relatively 
voluminous,  strongly-muscled,  bulb  (text  figs.  2,  3),  opening 
anteriorly  to  the  crop  through  a  cruciform  portal,  and  poster- 
iorly into  the  midgut  through  a  slender,  tubular,  stomodaeal 
valve. 

From  the  structure  of  the  organ  it  is  clear  that  this  type  of 
proventriculus  represents  a  distinct  adaptation  to  the  fluid 
nature  of  the  diet.  It  is,  in  fact,  nothing  but  a  pump,  with 
intake  and  exhaust  valves  provided  respectively  by  the  portal 
and  the  stomodaeal  valve.  Proventricular  activity  consists  of 
rhythmic  contractions  and  expansions  of  the  bulb  by  means  of 
which  a  regulated  pumping  is  accomplished  (Bailey  '52,  Schrei- 
ner  '52).  Small  particulate  matter,  such  as  pollen  grains,  present 
no  obstacle  to  proventricular  pumping.  We  know,  for  instance, 
that  in  Prosopis,  Vespa,  and  Bombus,  even  relatively  dense  sus- 
pensions of  pollen  grains  are  effectively  transferred  to  the  mid- 
gut without  proventricular  obstruction  (Bailey  '54).  In  Apis, 
the  proventriculus  may  even,  under  special  circumstances,  con- 
vey pollen  grains  to  the  midgut  independently  from  their  liquid 
medium   (Bailey   '52,  Schreiner   '52)  ;  but  this  filtering  ability 


442  BULLETIN  :   MUSEUM  OF  COMPARATIVE  ZOOLOGY 

is  probably  secondary  to  the  primary  fluid-pumping  function  of 
the  organ  (Bailey  '54). 

Among  the  hymenopterous  insects  thus  far  investigated,  the 
proventriculus  is  monotonously  uniform  in  structure  from  fam- 
ily to  family.  This  circumstance  throws  into  striking  relief  the 
exceptional  group :  the  ants.  Within  this  single  medium-sized 
family,  the  proventriculus  shows  a  greater  diversity  of  structural 
types  than  can  be  found  in  any  other  insect  family  —  greater 
even  than  in  most  entire  orders. 

According  to  the  theory  of  Wheeler  ('23),  a  fundamental 
bond  of  social  life  among  the  ants  is  the  exchange  of  nutrient 
through  regurgitative  feeding.  In  adaptation  to  regurgitative 
feeding  the  crop  assumes  a  new  and  overwhelmingly  important 
function  in  the  social  community.  It  serves  not  only  as  a  recep- 
tacle for  the  nutrient  reserves  of  the  individual,  but  also  as  a 
communal  reservoir,  or,  as  Forel  aptly  termed  it,  a  "social 
stomach,"  from  which  the  non-foraging  members  of  the  com- 
munity may  derive  their  nourishment.  Some  of  the  higher  ants, 
in  which  regurgitative  feeding  achieves  its  highest  degree  of 
specialization,  have  even  developed  special  storage  castes  ("re- 
pletes")  with  enormously  distended  crops  and  expansible  gasters 
(e.g.  Leptomyrmex,  Melophorus,  Prenolepis,  Myrmecocystus, 
Proformica,  etc.). 

In  ants,  as  in  all  Hymenoptera,  the  proventriculus  serves  pri- 
marily as  a  pump.  However,  the  development  of  a  crop  capable 
of  storing  nutrient,  not  only  in  amounts  far  beyond  those  re- 
(luired  by  the  individual  forager,  but  also  for  prolonged  periods 
of  time,  has  been  accompanied  by  modifications  in  the  proventric- 
ulus allowing  that  organ  to  assume  the  additional  function  of 
effectively  damming  the  posterior  outlet  of  the  crop.  The  ant 
proventriculus  is  thus  seen  to  serve  a  dual  purpose,  being  re- 
sponsible not  only  to  the  individual,  for  whom  it  regulates  the 
nutrient  supply  to  the  midgut,  but  also  to  the  community,  which 
it  serves  by  acting  as  a  passive  dam  to  the  "social  stomach."

a  dam,  the  ant  proventriculus  has  solved  its  new  mechanical 
problems  by  means  of  a  number  of  different  morphological 
changes,  accounting  for  the  extraordinary  diversity  in  structure 
by  which  the  organ  has  come  to  express  itself  in  the  ants. 

The  present  study  has  as  its  chief  objectives  the  analysis  of 
structure,  and  the  explanation  of  function,  of  each  of  the  princi- 
pal kinds  of  proventriculi  known  to  occur  among  the  ants.  This 
structural  analysis  draws  from,  and  is  resynthesized  with  a  view 
to  augmenting,  the  general  body  of  knowledge  concerning  for- 
micid  evolution.  All  three  elements  of  this  approach  —  anatomi- 
cal, mechanical,  and  phylogenetic  —  have  been  inextricably  in- 
volved in  each  step  of  the  study. 

The  ant  proventriculus  has  been  the  subject  of  considerable 
interest  in  the  past ;  yet,  despite  several  involved  descriptions 
of  its  anatomy  that  have  appeared,  its  exact  function  and  mode 
of  action  have  never  been  properly  understood.  Due  to  its  struc- 
tural variability,  the  organ  has  been  used  extensively  as  a  taxo- 
nomic  character  in  the  classification  of  the  Dolichoderinae  and 
Formieinae,  and  in  phylogenetic  speculations  concerning  these 
and  other  groups.  The  first  accurate  anatomical  study  of  the 
dolichoderine-formicine  proventriculus  was  that  of  Forel  (1878). 
Emery  (1888)  followed  up  Forel 's  work  in  a  classic  comparative 
monograph,  still  the  basic  reference  on  this  organ.  He  reviewed 
most  of  the  dolichoderine  and  formicine  tribes,  as  well  as  the 
aberrant  myrmicine  tribe  Cephalotini.  Additional  concise  de- 
scriptions of  the  proventriculus  of  the  Dolichoderinae  and  For- 
micinae were  given  in  1912  and  1925  in  the  fascicles  of  Wyts- 
man's  Genera  Insectorum  dealing  with  these  groups.  The  most 
recent  work  deals  only  with  the  aneuretine  proventriculus  (Wil- 
son, Eisner  et  al.  '56)  and  with  the  specialized  camponotine 
type  (Eisner  and  Wilson  '52).  Wherever  necessary,  reference  is 
made  to  these  works  throughout  this  paper. 

The  suprageneric  classification  of  the  family  Formicidae  fol- 
lowed here  is  that  advanced  by  Brown  ('54).  The  aneuretines 
are  given  subfamilial  rank  in  accordance  with  Wilson,  Eisner 
et  al.  ('56).  On  the  advice  of  W.  L.  Brown,  Jr.  and  E.  0. 
Wilson,  I  am  avoiding  the  use  of  tribal  designations,  classifica- 
tion at  this  level  being  artificial  and  currently  under  revision.

PART  I 

MATERIALS  AND  METHODS 

It  is  impossible  fully  to  understand  any  proventriculus  with- 
out considering  the  closely  interdependent  structure  and  func- 
tion of  the  two  major  organic  constituents,  the  cuticular  frame- 
work and  the  muscular  envelope.  Structural  data  were  obtained 
principally  from  two  types  of  microscopical  preparations.  The 
lirst  of  these  consisted  of  the  isolated  proventricular  framework 
divested  of  all  attached  cellular  portions.    The  second  type  of 


446  BULLETIN  :   MUSEUM   OP  COMPARATIVE  ZOOLOGY 

preparation  consisted  of  the  simple  serial  sections  of  the  whole 
proventricuhis.  The  functional  and  phylogenetic  considerations 
were  derived  from  a  careful  comparative  study  of  these  prepara- 
tions and  such  other  incidental  data  as  became  available. 

The  following  is  a  brief  outline  of  the  procedure  used  in  the 
making  of  the  preparations  and  a  brief  account  of  the  method  of 
illustration  employed,  with  a  consideration  of  its  limitations. 

Cuticular  framework  preparations 

This  method  is  outlined  here  in  some  detail,  since  it  may  be  of 
aid  to  the  systematist  who  uses  the  ant  proventricuhis  as  a 
taxonomic  character. 

In  order  to  remove  all  cellular  constituents  from  the  proven- 
triculus,  the  whole  ant  is  immersed  in  hot  (ca.  90°C)  10%  aque- 
ous KOH  for  V2  to  1  hour,  or  in  the  same  solution  at  room 
temperature  for  8  to  15  hours.  Specimens  from  either  fluid 
preservative  or  dry  mounts  may  be  treated  in  this  way. 

The  whole  ant  is  then  transferred  through  several  changes  of 
distilled  water  to  remove  the  alkali,  and  finally  to  70%  alcohol, 
where  the  proventricuhis  is  dissected  out.  To  this  end,  a  small 
window  is  first  cut  in  the  gaster,  through  which  the  crop  can 
readily  be  seen  as  a  thin  cuticular  sac  extending  backwards  from 
the  petiole;  the  proventricuhis  itself  appears  as  a  small  terminal 
protuberance  on  the  crop.  At  no  time  should  the  proventriculus 
be  severed  from  the  crop,  since  the  crop  provides  an  ideal  hold- 
fast by  which  the  proventriculus  may  be  transferred  through 
the  various  solutions  which  follow.  Furthermore,  the  positional 
relationship  and  proportions  of  the  two  organs  are  in  themselves 
important  things  for  the  observer  to  note.  The  crop  with  the 
proventriculus  is  seized  with  fine  forceps,  extracted  from  the 
gaster  and  transferred  directly  into  the  stain. 

Chlorazol  black  E  (1%  in  70%  alcohol)  proved  to  be  the 
most  suitable  of  the  stains  used  (Pantin  '48).  One  to  five  min- 
utes suffices  for  adequate  staining;  overstained  specimens  are 
usually,  but  not  always,  readily  destained  in  70%  alcohol. 

Other  cuticular  stains  such  as  eosin,  acid  fuchsin,  fast  green 
and  picro-creosote  (Kennedy  '49)  offered  no  advantages  over 
chlorazol  black  E.  Acid  fuchsin  occasionally  proved  useful  as  a 
counterstain  to  chlorazol  black ;  the  latter  stain  has  a  low  affinity 


EISNER:  ANT  PROVENTRICULUS  447 

for  the  cupolar  or  sepalar  region  of  the  proventriculus,  while 
acid  fuehsin  has  a  strong  affinity  for  these  regions  only,  and 
was  therefore  especially  useful  where  it  was  otherwise  impossible 
to  delimit  the  exact  extent  of  the  portal  opening  of  the  pro- 
ventriculus. 

The  specimen  is  then  passed  through  two  changes  of  100% 
alcohol  for  about  3  minutes  each,  and  into  cedar  oil,  where  it 
may  be  stored  indefinitely.  If  whole  mounts  are  desirable,  the 
cedar  oil  is  rinsed  off  with  xylol,  and  the  specimen  mounted 
under  a  coverslip  in  balsam  or  synthetic  resin. 

In  cases  in  which  valuable  dried  specimens,  such  as  holotypes 
or  uniques,  must  be  studied,  the  proventriculus  can  usually  be 
removed  without  materially  damaging  the  ant.  To  isolate  the 
proventriculus  from  such  a  sample,  the  specimen  is  first  relaxed 
in  a  suitable  fluid,  such  as  Barber's  fluid  or  a  mild  detergent- 
water  mixture,  and  then  the  crop  and  proventriculus  are  ex- 
tracted together  through  an  incision  in  the  membrane  between 
the  first  and  second  gastric  segments.  The  location  of  the  in- 
cision may,  of  course,  vary  with  the  kind  and  condition  of  the 
ant,  but  a  careful  and  commonsense  approach  adapted  to  the 
individual  specimen  will  usually  yield  a  good  proventriculus. 
As  Forel  long  ago  noted,  this  operation  can  be  performed  so 
neatly  that  the  re-moiinted  ant  is  only  the  better  for  its  inci- 
dental bath.  Once  isolated,  the  crop  and  proventriculus  can  be 
treated  with  cold  10%  KOH  until  free  of  soft  tissues,  and  then 
handled  like  any  other  proventriculus. 

Histological  serial  sections 

Unfortunately,  many  of  the  genera  available  for  this  study 
were  either  dried,  or  had  been  stored  in  alcohol  for  many  years, 
which  rendered  them  useless  for  histological  study.  There  was 
also  available,  however,  an  adequate  series  of  representative 
genera  properly  preserved  by  histological  fixatives  (Schaudinn's, 
Bourn's,  Carnoy's).  Some  of  the  material  that  had  been  pre- 
served in  alcohol  for  relatively  short  periods  of  time  (about  5 
years  or  less)  yielded  adequate  and,  in  fact,  often  remarkably 
good  histological  preparations. 

Serial  sections  were  made  by  routine  histological  technique. 
The  proventrieuli  were  embedded  in  Tissuemat  [}/%  hour),  sec- 


448  BULLETIN:    MUSEUM   OF  COMPARATIVE  ZOOLOGY 

tioned  at  5  to  10  micra,  and  stained  with  Ehrlich's  hematoxylin 
and  eosin,  or  in  some  eases  with  Masson's  trichrome,  Mallory's 
triple  or  Heidenhain's  iron-hematoxylin.  Both  longitudinal  and 
transverse  sections  were  always  made. 

Method  of  Illustration 

The  drawings  of  ant  proventriculi  used  throughout  this  paper 
are  of  two  distinct  types. 

The  first  of  these  consists  of  three-dimensional  semi-diagrams 
of  the  whole  cuticular  framework  of  the  proventriculus.  The 
camera  lucida  drawings  on  which  these  illustrations  are  based 
were  made  as  follows.  With  the  proventriculus  submerged  in 
cedar  oil  in  a  small  dish  placed  under  the  dissecting  microscope, 
the  fine,  drawn-out  end  of  a  glass  capillary  needle  was  introduced 
into  the  proventriculus  through  the  point  of  intersection  of  the 
slit-like  anterior  openings  (portal)  of  the  organ.  The  opposite 
end  of  the  needle  was  held  in  a  universal  joint  by  means  of 
which  the  glass  needle  could  be  turned  and  the  proventriculus 
oriented  in  the  desired  way.  The  hollow  glass  needle  draws  in 
t lie  oil  by  capillarity,  and  in  so  doing  becomes  almost  transparent 
and  does  not  hide  any  of  the  structural  details  of  the  proventric- 
ulus. Camera  lucida  drawings  were  made  with  15x  ocular  and 
6x  objective.  The  histological  serial  sections  were  of  aid  in 
filling  in  some  of  the  more  inconspicuous  structural  detail,  not 
seen  through  the  dissecting  microscope. 

In  some  of  those  few  proventriculi  studied  in  which  the  cuticu- 
lar framework  is  excessively  thin  and  flaccid,  usually  losing  its 
shape  in  the  absence  of  the  supporting  musculature  (the  pon- 
erine,  eerapachyine,  dory  line,  and  myrmicine  representatives, 
and  to  some  extent  also  the  aneuretines  and  pseudomyrmecines), 
the  drawings  are  in  large  part  reconstructions  based  on  the 
serial  sections,  and  are  labelled  as  diagrams. 

With  the  exception  of  the  conspicuous  rugae  on  the  outer 
margins  of  the  plicae  of  the  bulb,  no  effort  was  made  in  any  of 
these  drawings  to  represent  the  finer  details  of  cuticular  sculp- 
turing. Wherever  possible,  these  details  were  represented  in 
the  histological  drawings  discussed  below. 

For  the  purpose  of  clarifying  some  of  the  internal  intricacies 
of   the   proventriculi,   the   cuticular    framework   is   occasionally 


EISNER:   ANT  PROVENTRICULUS  44') 

represented  with  certain  sections  cut  away.  The  depiction  of 
the  cutaways  was  based  on  the  serial  sections. 

The  second  type  of  illustration  consists  of  semi-diagrams  of 
selected  histological  cross  sections  and  longitudinal  sections 
through  the  proventriculus,  and  were  made  with  the  aid  of  a 
camera  lucida. 

Due  to  the  variety  of  fixatives  used,  the  material  served  only 
for  gross  histological  study,  and  lacked  the  uniformity  necessary 
for  comparative  cytological  observations  of  any  value.  The 
illustrations  are  therefore  semi-diagrammatic,  inasmuch  as  no 
attempt  was  made  to  represent  intracellular  detail.  In  a  limited 
number  of  cases  the  only  histological  sections  obtained  were 
oblique,  rather  than  transverse  or  longitudinal,  and  the  drawings 
represent  reconstructions  from  camera  lucida  outlines  of  the 
oblique  sections.  Wherever  such  reconstruction  was  employed, 
the  drawings  are  labelled  as  diagrams. 

The  outstanding  difficulty  encountered  in  the  interpretation 
of  the  histological  sections  was  raised  by  the  outermost  longi- 
tudinal muscle  fibers  of  the  proventriculus  (l.m.  3  or  similarly 
disposed  fibers).  These  fibers  usually  consist  of  only  a  few 
scattered  strands,  which  during  histological  processing  may 
shrink  away  from  their  insertions  on  the  cuticle,  thereby  be- 
coming easily  displaced,  especially  since  they  often  lack  the 
support  of  other  tissues  and  lie  free  in  the  hemocoel.  Tracing 
such  muscle  fibers  through  successive  sections  was  difficult  at 
best  and  sometimes  impossible.

450  BULLETIN  :    MUSEUM   OF  COMPARATIVE  ZOOLOGY 

The  proventriculus  of  Myrmecia  is  one  of  the  least  specialized 
among  that  of  ants,  and  in  most  major  respects  it  is  similar  to 
that  of  the  few  other  aculeate  hymenopterous  families  in  which 
the  organ  has  been  described. 

The  cuticular  framework  (Fig.  4)  consists  of  a  thin- walled, 
flask-shaped  bulb  (bl.),  opening  anteriorly  through  a  wide, 
roughly  cruciform  portal  (pt.).  The  Avails  of  the  bulb  are  four 
broad,  sclerotized,  inwardly-curved  plates,  joined  basally  and 
merging  into  the  slender,  tubular  stomodaeal  valve  (st.  vlv.). 
The  plates  are  separated  one  from  another  by  relatively  narrow 
longitudinal  strips  of  thin,  flexible  cuticle,  the  pleats  or  plicae 
(pi.).  The  plates  themselves  are  here  termed  inter  plicaries 
(inter pi.).  The  interplicaries  extend  free  beyond  the  plicae  and 
the  portal  to  project  into  the  lumen  of  the  crop  as  four  apically 
rounded  lobes  or  quadrants  (qd.),  collectively  constituting  the 
cupola  (cp.).  Actually,  the  cruciform  shape  of  the  portal  is  de- 
termined by  the  presence  of  the  cupolar  quadrants.  The  inner 
sclerotized  surface  of  the  quadrants  is  covered  with  relatively 
sparse  short  pile  (Figs.  10,  12). 

The  bulb  is  surrounded  by  a  strongly  developed  layer  of 
circular  muscles  (Figs.  10,  13,  14;  cm.).  With  the  exception  of 
the  innermost  fibers,  which  insert  on  the  lateral  margins  of  the 
plicae,  the  circular  muscles  envelop  the  bulb  without  attachment 
to  the  cuticle. 

The  longitudinal  muscles  are  arranged  in  three  distinct  groups 
(Figs.  10,  12,  13,  14;  l.m.l,  l.m.2,  l.m.3).  The  most  strongly 
developed  of  these  (l.m.l)  extends  over  the  interplicary  cuticle 
of  the  bulb,  originating  posteriorly  near  the  base  of  the  bulb  and 
inserting  anteriorly  on  the  quadrants  of  the  cupola.  A  second 
group  (l.m.2)  inserts  along  the  posterior  half  of  the  interplicary 
plates,  pierces  the  circular  muscles,  and  fans  out  to  become  a 
part  of  the  longitudinal  musculature  of  the  midgut.  The  third 
group  (l.m.3)  consists  of  only  a  few  scattered  fibers  that  insert 
on  the  quadrants,  and  extend  posteriorly  over  the  circular 
muscles  to  become  continuous  with  l.m.2. 

It  proved  impossible  to  determine  the  exact  fate  of  those 
longitudinal  muscles  that  approach  the  bulb  from  the  crop, 
although  the  preparations  suggested  that  these  fibers  distribute 
themselves  among  the  various  intrinsic  muscles  of  the  proventric- 
ulus (see  dotted  lines,  Fig.  10). 


EISNER:   ANT  PROVENTRICULUS  451 

lii  the  arrangement  of  its  longitudinal  muscles,  the  Myrmecia 
proventrieulus  is  unique :  all  other  ant  proventrieuli  examined, 
with  the  possible  exception  of  Pseudomyrmex,  Aneuretus  (see 
next  below)  and  some  genera  of  the  Poneroid  complex,  lack  the 
J.m.2  fibers. 

A  longitudinal  section  through  the  stomodaeal  valve  and  associ- 
ated structures  (Fig.  11)  shows  how  the  extremely  thin  and  flex- 
ible cuticular  intima  of  the  valve  extends  far  into  the  lumen  of 
the  midgut  and  then  turns  inside  out  and  back  upon  itself  so  as 
to  form  a  compound  tube.  A  strong  muscular  sphincter  embraces 
the  valve  at  the  point  of  emergence  from  the  bulb.  Figure  11 
is  of  interest  also  in  that  it  shows  in  histological  detail  the  nature 
of  the  foregut-midgut  junction.  Attention  is  called  to  the  con- 
spicuous columnar  cells  (a)  grouped  as  a  ring  around  the  stomo- 
daeal valve  at  the  point  where  the  latter  perforates  the  midgut. 
The  nature  of  these  cells  becomes  clear  from  the  work  of 
Dobrovsky  ('51)  who  has  shown  that  in  Apis  these  cells  form  a 
continuous  barrier  that  separates  the  foregut  from  the  midgut 
during  the  course  of  prepupal  reorganization.  At. this  time  the 
developing  stomodaeal  valve  is  held  back  as  an  invagination 
within  the  bulb,  and  it  is  not  until  later  that  the  cellular  barrier 
is  pierced  by  the  intrusion  of  the  valve  into  the  midgut.  A  point 
of  incidental  interest  is  that  the  basement  membrane  (b.m.). 
which  is  strongly  eosinophilic  and  readily  traced,  forms  a  con- 
tinuous sheet  over  the  foregut  and  midgut  epithelium. 

In  all  other  ant  proventrieuli,  the  stomodaeal  valve  is  essen- 
tially similar  to  that  of  Myrmecia,  and  except  for  some  minor 
(but  functionally  significant)  variation  in  the  degree  of  develop- 
ment of  the  muscular  sphincter  (see  page  478),  no  further  con- 
sideration will  be  given  to  the  stomodaeal  valve  in  subsequent 
proventrieuli. 

My  interpretation  of  the  function  of  the  Myrmecia  proventrie- 
ulus is  as  follows.  The  circular  and  longitudinal  muscles  act  as 
antagonists  to  one  another  in  compressing  and  expanding  the 
bulb.  By  the  combined  action  of  the  various  longitudinal  fibers, 
the  interplicary  plates  of  the  bulb  first  spread  apart  from  one 
another  with  the  unfolding  of  the  plicae,  and  then  are  flattened 
out.  The  quadrants  of  the  cupola  separate,  and  crop  fluid  is 
admitted  through  the  widened  portal  into  the  expanded  bulb.  A 
forward  flow  of  liquid  from  the  midgut  is  prevented  by  the 


452  BULLETIN  :    MUSEUM   OF  COMPARATIVE  ZOOLOGY 

stomodaeal  valve,  the  thin  wall  of  which  collapses  under  the 
pressure  of  the  midgut  contents.  By  the  contraction  of  its 
circular  muscles,  the  bulb  is  then  compressed  and  its  contents 
forced  back  through  the  stomodaeal  valve  into  the  midgut. 
Backflow  to  the  crop  is  hindered  by  the  tight  closure  of  the 
cruciform  portal  (approximation  of  the  quadrants)  and  by  a 
tight  folding  of  the  membranous  plicae,  closed  by  the  circular 
fibers  along  their  margins. 

In  addition  to  its  function  as  a  one-way  valve,  the  stomodaeal 
valve  undoubtedly  serves  also  as  a  flexible,  self-adjusting  link, 
which  by  bending  is  capable  of  adjusting  to  peristalsis  and  vol- 
ume changes  of  the  crop. 

The  proventriculus  of  Myrmecia  apparently  is  no  better 
adapted  to  serve  as  a  dam  for  the  crop  than  is  that  of  other 
Hymenoptera.  It  is  evident  from  the  structure  of  the  organ  that 
prolonged  damming  is  possible  only  if  either  the  cruciform  portal 
or  the  stomodaeal  valve  is  maintained  tightly  occluded  under 
sustained  muscular  contraction.  In  preserved  proventriculi  of 
all  Myrmecia  species  examined,  the  portal  was  always  seen  to  be 
slightly  agape,  suggesting  that  sustained  occlusion  is  main- 
tained exclusively  at  the  level  of  the  stomodaeal  valve,  which  in 
this  genus  is  provided  with  a  particularly  powerful  sphincter. 

Subfamily  PSEUDOMYRMECINAE 

PSEUDOMYRMEX   Lund 

Species  examined:  P.pallidus*  (F.Smith). 

In  its  principal  features,  the  proventriculus  of  Pseudomyrmex 
(Fig.  5)  is  similar  to  that  of  Myrmecia,  and  it  can  be  safely 
assumed  that  it  functions  in  much  the  same  way.  In  Pseudomyr- 
mex the  quadrants  of  the  cupola  are  shaped  to  fit  together  more 
closely  at  the  axis,  resulting  in  a  more  narrow  cruciform  portal, 
and  a  more  compact  cupola. 

The  Pseudomyrmex  material  available  was  in  such  a  poor  state 
of  preservation  that  exact  delineation  of  the  longitudinal  muscu- 
lature was  impossible.  Although  the  presence  of  l.m.l  and  l.m.3 
fibers  could  be  determined  with  certainty  (Figs.  15,  16),  there 
remains  some  doubt  concerning  the  presence  of  l.m.2.  A  few 
fibers,  strongly  suggestive  of  l.m.2  were  seen  in  cross  sections  to 


EISNER:   ANT   PROVENTRICULUS  453 

extend  through  the  circular  muscles  at  the  level  of  the  posterior 
third  of  the  bulb  (see  l.m.2  ( ?),  Fig.  16),  but  final  proof  of  the 
presence  of  l.m.2  must  await  further  investigation. 

Subfamily  ANEURETINAE 

AneURETUS    Emery 

Species  examined:  A.  simoni*  Emery. 

In  all  of  its  major  features,  this  proventriculus  (Fig.  6),  like 
that  of  Pseudomyrmex,  conforms  closely  to  that  of  Myrmecia. 

The  l.m.l  and  l.m.3  fibers  are  fully  retained  (Fig.  21).  Al- 
though I  found  no  evidence  for  the  presence  of  l.m.2  fibers,  I 
must  admit  that  some  uncertainty  remains  regarding  their  ab- 
sence ;  the  small  size  of  the  proventriculus,  and  the  rather  poor 
condition  of  the  preparations  available,  made  precise  observa- 
tions difficult. 

In  view  of  the  overall  structural  similarity  of  this  proventricu- 
lus with  that  of  Myrmecia  and  Pseudomyrmex,  its  function  is 
probably  also  much  the  same. 

Subfamily  DOLICHODERINAE 

HYPOCLINEA    Mayr 

Species  examined:  H.  piistulata*  (Mayr). 

The  cuticular  framework  of  the  proventriculus  of  Hypoclinea 
(Fig.  7),  although  distinctive  in  its  ovoid  bulb  and  flattened 
dome,  still  conforms  to  the  basic  structural  plan  of  Myrmecia, 
Pseudomyrmex,  and  Aneuretus,  except  that  the  plicae  have  be- 
come sclerotized  toward  the  base  of  the  bulb. 

Histologically,  the  longitudinal  musculature  has  undergone  a 
simplification  by  the  loss  of  l.m.2  (Fig.  17).  In  Hypoclinea  this 
could  be  ascertained  with  certainty.  Only  l.m.l  and  l.m.3  are  re- 
tained (Figs.  17-20).  As  will  be  recalled,  the  main  function  of 
l.m.2  in  Myrmecia  is  to  expand  the  bulb  by  pulling  outward  on 
the  interplicary  plates.  With  the  sclerotized  posterior  parts  of 
the  plicae,  the  base  of  the  bulb  in  Hypoclinea  forms  a  cup  of 
uninterrupted  relatively  thick  cuticle,  capable  of  elastic  ex- 
pansion by  itself  when  the  circular  muscles  relax.  L.m.2  has 
therefore  become  superfluous  and  is  lost.    The  l.m.l  and  l.m.3 


4.)4  BULLETIN  :    MUSEUM   OF  COMPARATIVE  ZOOLOGY 

fibers  serve  mainly  to  disengage  the  cupolar  quadrants  so  as  to 
open  the  bulbar  portal  during  the  intake  phase  of  proventricular 
activity,  and  from  their  attachment,  it  can  be  seen  that  they 
play  no  major  part  in  the  expansion  of  the  bulb  itself.  Except 
for  the  fact  that  bulb  expansion  has  become  a  passive  process, 
the  action  of  the  Hypoclinea  proventriculus  is  probably  similar 
to  that  of  Myrmecia. 

LEPTOMYRMEX    Mayr 

Species  examined:    L.  pollens*  Emery,  L.  cnemidatus  Wheeler. 

The  proventriculus  of  Leptomyrmex  (Fig.  9)  has  become 
specialized  in  several  major  respects.  The  cupola  is  character- 
istically concave  in  its  anterior  aspect.  The  bulb  is  relatively 
small,  and  occupies  less  than  the  posterior  half  of  the  proventric- 
ulus. In  the  anterior  half,  the  interplicary  plates  are  thickened 
and  pinched  inward  so  as  to  frame  a  narrow  cruciform  tract, 
the  occlusory  tract  (oec.  tr.),  an  inward  extension  of  the  cruci- 
form portal  of  the  cupola.  The  entire  occlusory  tract  and  cupola 
are  lined  with  dense,  long,  pile  (Figs.  23,  24). 

The  walls  of  the  occlusory  tract  are  still  articulated  laterally 
by  thin,  flexible  plicae,  but  as  the  occlusory  tract  opens  pos- 
teriorly into  the  bulb,  the  plicae  lose  their  membranous  character 
and  thicken  to  become  sclerotized  and  hollow  (C-shaped  in  cross 
section),  reinforcing  the  bulb  at  its  four  angles. 

Histologically,  Leptomyrmex  resembles  Hypoclinea  in  that 
l.m.2  is  absent,  and  only  l.m.l  and  l.m.3  are  retained  (Figs.  23, 
24,  25). 

In  its  pumping  action,  the  proventriculus  of  Leptomyrmex 
resembles  that  of  Hypoclinea  inasmuch  as  the  bulb,  being  later- 
ally reinforced  by  sclerotized  plicae,  is  so  constituted  as  to  ex- 
pand through  its  own  elasticity.  The  longitudinal  muscles  serve 
only  to  widen  the  occlusory  tract  (the  walls  of  which  are  allowed 
to  separate  by  the  flexibility  of  the  plicae),  thereby  opening  the 
pathway  by  which  fluid  enters  the  bulb. 

In  the  acquisition  of  an  occlusory  tract  we  see  in  Leptomyrmex 
the  first  major  specialization  serving  to  improve  the  damming 
potential  of  the  proventriculus.  The  extensive,  relatively  nar- 
row, and  densely  pilose  occlusory  tract  would  seem  capable  by 
itself  of  effectively  containing  to  a  large  extent  the  posteriorly 


EISNER:  ANT  PROVENTRICULUS  455 

directed  pressure  exerted  by  the  crop  contents.  Thus,  the  need 
for  muscular  force  in  the  maintenance  of  proventricular  occlu- 
sion has  become  somewhat  reduced,  and  the  efficiency  of  the 
damming  action  of  the  proventriculus  correspondingly  increased. 

LlOMETOPUM  Mayr 

Species  examined:  L.  sp.*  (near  apiculatum  Mayr). 

Although  superficially  Liometopum  (Fig.  8)  is  quite  distinct 
from  Leptomyrmex,  its  general  structural  plan  betrays  its  debt 
to  a  stock  common  to  these  two  genera.  Like  Leptomyrmex 
Liometopum  has  an  extensive  occlusory  tract,  and  the  bulb  itself 
is  considerably  reduced  in  size.  Both  the  occlusory  tract  and 
cupola  bear  dense,  long  pile  (Fig.  22).  In  contrast  to  that  of 
Leptomyrmex,  the  cupola  of  Liometopum  is  broad  and  convexly 
reflexed,  and  is  somewhat  more  rigid  in  consistency  than  any 
previously  discussed.  The  plicae  of  Liometopum  are,  as  in  Lepto- 
myrmex, fully  sclerotized  at  the  level  of  the  bulb.  Unlike  in 
Leptomyrmex,  the  plicae  are  also  somewhat  thickened  at  the  level 
of  the  occlusory  tract,  although  they  undoubtedly  still  retain 
sufficient  flexibility  to  be  readily  unfolded  when  the  occlusory 
tract  is  dislodged  during  bulbar  intake.  The  ready  mobility 
of  the  occlusory  tract  is  clearly  evidenced  by  prying  with  a  glass 
needle.   The  muscles  (Fig.  22)  are  arranged  as  in  Leptomyrmex. 

In  its  pumping  action,  Liometopum  cannot  differ  grossly  from 
Leptomyrmex.  Some  improvement  might  be  afforded  by  the  more 
rigid  reflexed  cupola,  which  acts  to  assure  a  passively  maintained 
intrusion  of  the  anterior  proventriculus  into  the  crop  and 
thereby  provides  greater  freedom  of  access  to  the  cruciform 
portal.  In  the  genera  discussed  previously,  superficially  similar 
intrusion  of  proventriculus  into  crop  is  also  seen,  but  in  these 
the  texture  of  the  cupola  is  largely  membranous,  and  its  intru- 
sion seems  to  be  maintained  entirely  by  the  tension  of  those 
longitudinal  muscles  extending  from  the  crop  over  the  pro- 
ventriculus. 

In  its  action  as  a  dam,  the  Liometopum  proventriculus  shows 
some  improvement  over  that  of  Leptomyrmex,  in  that  the  oc- 
clusory tract  is  provided  with  somewhat  sclerotized  and  there- 
fore spring-like  plicae,  serving  as  adjuncts  to  the  circular 
muscles  in  sealing  the  occlusorv  tract.

TAPINOMA    Forster 

Species  examined:  T.  sessile*  (Say). 

The  proventriculus  of  Tapinoma  (Fig.  26)  is  much  more 
specialized  in  structure  than  any  of  the  proventriculi  discussed 
so  far.  It  is  a  strong,  rigid,  subglobose  structure,  consisting  of 
a  well-developed  bulb  surmounted  by  a  cupola  made  of  thick, 
strongly  sclerotized  cuticle.  The  face  of  the  cupola  is  ornamented 
with  a  characteristic,  raised,  densely  pilose  reticulum  (Figs.  27, 
28).  This  sculpturing  extends  inward  to  line  the  slit-like  cruci- 
form portal.  This  portal  opens  almost  immedia'tely  into  the 
bulb,  and  does  not  proceed  farther  inward  to  form  an  extensive 
occlusory  tract  as  in  Leptomyrmex  and  Liomeiopum.  The  bulb 
itself  is  characterized  by  the  extreme  rigidity  and  c-shaped 
cross  sections  of  the  plicae   (Figs.  26,  29). 

The  longitudinal  musculature  has  undergone  some  new  special- 
ization (Figs.  27,  29).  One  group  of  fibers,  consisting  of  only 
a  few  strands,  joins  the  margins  of  the  cupola  to  the  sides  of 
the  bulb.  On  the  basis  of  their  position  inside  the  circular 
muscles,  I  consider  these  fibers  as  homologues  of  l.m.l  of  previ- 
ous proventriculi ;  from  these  they  differ  only  in  their  more 
peripheral  insertion  on  the  cupola.  A  second  group  of  longi- 
tudinal fibers  inserts  anteriorly  on  the  crop  intima,  in  such  a 
way  as  to  maintain  the  posterior  fold  surrounding  the  proven- 
triculus, and  originates  posteriorly  on  the  base  of  the  bulb  near 
the  origin  of  the  stomoclaeal  valve.  This  was  the  first  proven- 
triculus studied  in  which  the  full  course  of  these  fibers,  including 
origin  and  insertion,  could  be  traced  with  ease.  Possibly  they 
are  homologues  of  l.m.3  that  have  shifted  their  insertion  outward 
to  the  crop  intima  and  have  taken  posterior  origin  secondarily 
on  the  bulb.  This  interpretation  is  reasonable,  in  view  of  the 
absence  of  any  other  obvious  l.m.3  homologues  in  Tapinoma. 
There  exists,  in  fact,  some  evidence  that  in  previously  discussed 
proventriculi,  the  outermost  components  of  l.m.3  are  in  a  similar 
wise  already  fold-maintaining  fibers,  but  in  these  cases  origin 
and  insertion  could  usually  not  be  made  out,  and  the  fibers 
seemed  to  extend  from  the  crop  over  the  proventriculus  with- 
out attachment  to  the  cuticle.  In  view  of  the  uncertainty  that 
remains  concerning  the  identity  of  these  fibers  in  Tapinoma,  and 


EISNER:   ANT   PROVENTRICULUS  457 

subsequent  dolichoderines  having  similarly  placed  fibers,  they  are 
labelled  as  Z.ro.3(?). 

In  its  function  as  a  dam,  Tapinoma  shows  significant  im- 
provement over  previous  proventriculi.  In  the  resting  proven- 
triculus,  the  quadrants  of  the  cupola  are  rigidly  maintained  in 
the  adducted  position  and  the  portal  orifice  is  held  to  a  narrow 
slit  by  the  spring-like  reinforcement  of  the  strongly  sclerotized 
plicae.  Here  is  seen  the  first  instance  in  which  proventricular 
damming  is  probably  accomplished  without  any  muscular  rein- 
forcement whatsoever. 

The  structural  advances  in  the  Tapinoma  proventriculus  are, 
of  course,  linked  closely  with  functional  changes  in  the  pump- 
ing action.  The  restriction  of  the  portal  orifice  to  a  narrow  slit 
tends  to  handicap  the  ingress  of  fluid  during  bulbar  intake,  and 
it  becomes  necessary  to  widen  the  portal  through  a  disengage- 
ment of  the  cupolar  quadrants.  Tapinoma  lacks  an  effective 
occlusory  tract,  and  only  a  minimal  dislocation  of  the  quad- 
rants suffices  for  the  ready  access  of  fluid  into  the  bulb.  I 
believe,  in  fact,  that  a  wide  disengagement  of  the  quadrants  is 
not  only  unnecessary  but  impossible.  The  thickness  and  rigidity 
of  the  cupola  and  the  full  sclerotization  of  the  bulbar  plicae 
(these  acting  as  spring  antagonists  to  the  quadrant  retractor 
muscles  (l.m.l))  speak  for  a  very  narrow  range  of  mobility  of 
the  quadrants.  The  narrowness  of  this  range  is  further  demon- 
strated by  the  resistance  to  displacement  of  the  portal  when  a 
glass  needle  is  inserted.  It  is  interesting  to  note  in  this  con- 
nection that  l.m.l  inserts  on  the  rim  of  each  quadrant,  thereby 
achieving  optimal  leverage. 

When  the  circular  muscles  contract,  the  bulb  is  compressed 
and  fluid  is  forced  back  into  the  midgut  in  the  usual  fashion. 
Backflow  into  the  crop  is  prevented  by  a  maximal  compression 
of  the  cruciform  portal  and  a  tight  engagement  of  its  pilose 
lining.  During  the  subsequent  relaxation  of  the  circular  muscles, 
the  bulb  expands  under  the  intrinsic  elasticity  of  its  cuticular 
framework.  In  this  expansion,  the  spring-like  plicae  play  an 
important  role.  Simultaneously,  the  portal  orifice  is  forced 
slightly  agape  under  tension  from  l.m.l,  and  crop  fluid  rushes 
into  the  newly  emptied  and  now  expanding  bulb.

AZTECA   Forel 

Species  examined:  A.  sp*  (common  ochraceous  species  from  Vera 
Cruz,  Mexico),   A.  instabilis    (F.   Smith). 

Although  in  general  shape,  constitution  of  the  bulb  and  ar- 
rangement of  the  musculature,  the  proventriculus  of  Azteca 
(Fig.  30)  seems  close  to  that  of  Tapinoma,  it  has  certain  features 
that  suggest  that  it  may  stand  alone  as  an  evolutionary  offshoot. 

The  cupola  is  unique  in  that  the  four  quadrants  are  each 
deeply  and  angularly  excised,  lending  the  cupola  a  characteristic 
cruciform  shape  in  frontal  view.  In  section,  the  strongly  scler- 
otized  cuticle  of  the  cupola  is  seen  to  possess  an  inner  zone 
composed  of  closely  approximated  cuticular  hairs  which  give  it 
a  finely  and  evenly  striated  appearance.  These  hairs  extend 
inward  along  the  cruciform  portal  to  line  a  short  occlusory  tract. 
In  possessing  this  tract,  Azteca  further  differs  from  Tapinoma. 

In  musculature  (Fig.  31)  the  Azteca  proventriculus  does  not 
differ  greatly  from  that  of  Tapinoma.  Emery  (1888)  claimed 
a  complete  absence  of  longitudinal  muscles  in  Azteca  instabilis 
(F.  Smith),  but  he  probably  just  missed  them. 

The  Azteca  proventriculus  at  rest  is  maintained  in  the  oc- 
cluded state  by  its  intrinsic  elasticity  in  much  the  same  way  as  in 
Tapinoma,  and  it  can  therefore  also  serve  effectively  as  a  passive 
dam  to  the  crop.  Its  damming  action  is,  in  fact,  improved  over 
that  of  Tapinoma,  owing  to  the  presence  of  the  occlusory  tract. 

Although  obvious  structural  similarities  render  it  likely  that 
the  proventriculus  of  Tapinoma  and  Azteca  function  in  much 
the  same  way,  it  is  not  clear  to  me  whether,  during  the  active 
intake  phase  of  bulb  operation  in  Azteca,  there  is  a  full  disen- 
gagement of  the  cupolar  quadrants,  or  whether  disengagement  is 
damped  as  in  Tapinoma.  In  Azteca,  the  presence  of  an  occlusory 
tract  may  offer  sufficient  resistance  to  the  inflow  of  fluids  to  make 
its  opening  necessary.  The  angular  excision  of  each  quadrant 
may  confer  greater  flexibility  upon  the  cupolar  portal  arrange- 
ment, thus  facilitating  the  action  of  the  strong  "retractors" 
(l.m.l)  found  in  Azteca.  Further  evidence  for  mobility  of  the 
occlusory  tract  is  demonstrated  by  its  relatively  easy  displace- 
ment  when   a   glass   needle   is   introduced. 

The  five  genera  Forelius,  Dorymyrmex,  Turneria,  Froggat- 
tella,  and  Iridomyrmex  are  unmistakably  related  on  the  basis  of 


EISNER  :   ANT  PROVENTRICULUS  450 

proventricular  structure.  In  this  series,  the  proventriculus 
achieves  its  highest  degree  of  specialization  among  the  Dolicho- 
derinae.  An  understanding  of  the  structural  intricacies  of  these 
proventriculi  is  perhaps  best  accomplished  by  considering  first 
the  most  complex  proventriculi  of  the  series  {Iridomyrmex, 
Frog  gat  tella,  Turneria)  and  then  their  more  simple  evolu- 
tionary relatives  (Dorymyrmex,  Forelius). 

Iridomyrmex  Mayr 

Species  examined:  I.  detect  us*  (F.  Smith),  I.  viridiaeneus* 
Viehmeyer,  /.  punctatissimus  Emery,  I.  nitidus  Mayr. 

The  proventriculus  of  Iridomyrmex  (Figs.  32,  44,  45)  features 
a  broad,  strongly  reflexed  cupola  with  involuted  margins,  hold- 
ing tightly  within  its  hollow  a  greatly  reduced  bulb.  (Caste 
dimorphism  is  displayed  in  the  relative  development  of  cupola 
and  bulb ;  in  the  female  caste,  the  bulb  is  slightly  larger,  and 
barely  projects  from  beneath  the  cupolar  shell.) 

The  cupola  is  primarily  divided  into  four  quadrants  by  the 
cruciform  portal  in  the  usual  fashion.  A  major  new  development 
is  the  secondary  division  of  the  quadrants,  each  of  which  is  split 
radially  by  a  narrow  phragma  (phr.). 

The  external  cupolar  cuticle  is  covered  by  dense,  fine,  short 
pile  (Figs.  34,  35),  extending  into  the  cruciform  portal.  A  simi- 
lar pilose  vestiture,  but  slightly  longer,  was  already  seen  to  cover 
the  cupola  of  Azteca. 

Each  arm  of  the  cruciform  portal  opens  into  a  vestibular  cleft 
or  sinus  (Figs.  32,  35;  sin.),  which  in  turn  communicates  with 
the  mesial  lumen  of  the  bulb  via  a  submedian  zone  of  construc- 
tion (Figs.  32,  35;  a).  The  zones  of  construction  are  secondary 
developments  within  the  bulb  proper  that  have  arisen  in  response 
to  a  functional  need  to  be  discussed  below.  The  bulb  is  further 
characterized  by  the  subdeltoid  cross  section  of  the  plicae. 

Histologically,  the  proventriculus  is  seen  to  lack  all  intrinsic 
longitudinal  muscles  (Figs.  34,  35).  There  remain  only  those 
fibers  (l.m.3)  that  maintain  the  posterior  fold  of  the  crop  sur- 
rounding the  cupola. 

An  outstanding  advance  in  Iridomyrmex  is  the  complete  en- 
casement of  the  bulb  within  the  rigid,  reflexed  cupola,  a  circum- 
stance that  tends  to  render  the  bulb  motionbound.  This  handicap 


460  BULLETIN  :    MUSEUM   OF  COMPARATIVE  ZOOLOGY 

has  been  overcome  by  the  development  of  the  cupolar  phragmata, 
which  act  as  flexible  radial  hinge-lines,  allowing  the  cupolar  seg- 
ments to  yield  inward  to  the  contraction  of  the  bulb.  The 
powerful  development  of  the  circular  muscles  (Figs.  34,  35) 
reflects  the  added  burden  imposed  on  the  bulb  by  the  need  for 
embowing  the  cupolar  segments  during  bulbar  contraction.  The 
bulbar  expansion  that  follows  is  activated  not  only  by  the  intrin- 
sic elasticity  of  the  bulb  itself,  but  also  by  the  cupolar  segments, 
which,  after  becoming  embowed  during  bulbar  contraction, 
spring  back  to  their  original  position  and  carry  along  the  walls 
of  the  bulb. 

The  necessary  development  of  radial  hinge-lines,  however, 
brings  with  it  a  new  difficulty.  During  bulbar  contraction,  the 
lateral  arms  of  the  cruciform  portal  tend  to  be  forced  open  by 
the  contraction  of  the  circular  muscles  (see  Fig.  35)  instead 
of  becoming  occluded,  as  would  be  the  case  if  the  cupolar  quad- 
rants were  not  pleated.  It  therefore  has  become  necessary  to 
develop  a  secondary  valve  seal  in  the  form  of  the  constriction 
zones  within  the  bulbar  lumen.  During  bulb  contraction,  the 
four  constriction  zones  close  early  in  each  pumping  cycle,  and 
serve  to  prevent  leakage  from  bulb  to  crop. 

Since  lridomyrmex  has  lost  all  intrinsic  longitudinal  muscles, 
it  is  incapable  of  actively  expanding  the  cruciform  portal  during 
bulb  expansion.  The  need  for  such  expansion  is  avoided  by  the 
reduction  of  bulb  size  (relative  to  portal  orifice)  and  also  because 
resistance  to  inflow  is  minimized  in  the  absence  of  an  occlusory 
tract. 

This  proventriculus  is  ideally  suited  to  serve  as  a  passive  dam. 
The  very  narrow,  densely  pilose  portal,  maintained  immobile  by 
the  rigid  bracing  of  the  bulbar  core  within  the  cupola,  acts  as  an 
effective  plug  guarding  the  outlet  of  the  crop ;  fluid  can  probably 
be  forced  inward  past  the  portal  only  under  suction  pressure 
exerted  by  the  bulb.

Species  examined:    T.  sp*    (near  pacifica  Mann,  collected  by 
B.  0.  Wilson  in  New  Hebrides,  1954-1955). 

In  these  two  genera  the  proventriculus  is  identical  in  all 
respects  to  that  of  Iridomyrmex.  Caste  dimorphism  is  again 
manifested  in  the  slightly  longer  bulb  in  the  female. 

DORYMYRMEX    Mayr 

Species  examined:  D.  ensifer*  Forel. 

On  the  basis  of  the  proventriculus,  Dorymyrmex  (Figs.  42, 
43)  may  be  considered  close  to  the  direct  evolutionary  antecedent 
of  Iridomyrmex. 

In  Dorymyrmex,  unlike  Iridomyrmex,  the  posterior  third  of 
the  bulb,  constituting  the  most  voluminous  and  therefore  the 
contractile  portion  of  the  bulb  proper,  is  free  and  projects  from 
beneath  the  cupolar  shell.  Each  cupolar  quadrant  is,  as  in 
Iridomyrmex,  incised  by  radial  hinges  or  phragmata,  but  in- 
cision is  incomplete  and  stops  considerably  short  of  the  cupolar 
summit.  As  in  Iridomyrmex,  the  cupola  and  portal  bear  short 
dense  pile,  and  the  plicae  of  the  bulb  are  subdeltoid  in  cross 
section.  There  is  no  trace  of  intrinsic  longitudinal  muscles,  and 
there  persist  only  those  fibers  (l.m.3)  that  sustain  the  circum- 
cupolar  fold  of  the  crop  (Fig.  37,  representing  a  longitudinal 
section  through  the  proventriculus  of  Conomyrma,  may  be  taken 
also  to  represent  Dorymyrmex) .  Dorymyrmex  has  not  acquired 
the  secondary  valve-seal  mechanism  provided  in  the  bulb  of 
Iridomyrmex  in  the  form  of  submesial  zones  of  constriction. 

From  a  functional  standpoint,  one  can  readily  explain  the 
incipient  condition  of  quadrant  incision,  and  the  lack  of  a  sec- 
ondary valve-seal  mechanism  in  the  bulb.  Both  of  these  condi- 
tions are,  in  fact,  directly  attributable  to  the  incompleteness  of 
the  envelopment  of  bulb  by  cupola.  First  of  all,  the  fact  that 
most  of  the  contractile  portion  of  the  bulb  projects  from  be- 
neath the  cupola,  thereby  remaining  largely  unimpeded  in  its 
operation,  obviates  the  need  for  a  complete  radial  incision  oi 
the  quadrants.  Only  the  rim  of  the  cupola  must  yield  to  bulbar 
contraction,  and  consequently  only  the  rim  is  incised.  Secondly, 
since   the   quadrants   are   only   incompletely   pleated,   it   is   still 


462  BULLETIN  :   MUSEUM  OF  COMPARATIVE  ZOOLOGY 

possible  to  accomplish  a  valve-seal  at  the  level  of  the  portal 
during  bulbar  compression,  and  no  secondary  valvular  mechan- 
ism had  to  be  acquired. 

In  its  action  as  a  passive  dam,  the  Dorymyrmex  proventric- 
ulus  presents  the  same  structural  advantages  as  that  of  Iridomyr- 


mex. 


FORELIUS    Emery 

Species  examined:  F.foetidus*  (Buckley). 

In  its  basic  plan,  the  proventriculus  of  Forelius  (Figs.  40,  41) 
is  just  about  what  would  be  expected  of  a  precursor  member  of 
the  Dorymyrmex-Iridomyrmex  line.  Forelius  displays  in  in- 
cipient form  the  outstanding  feature  of  this  line,  namely  the 
envelopment  of  the  bulb  by  the  cupola;  most  of  the  bulb  is 
free,  and  only  the  anterior  third  is  encased  within  the  cupola. 
Relative  to  the  cupola,  the  bulb  is  much  larger  in  Forelius,  than 
it  is  in  Dorymyrmex  and  Iridomyrmex.  Forelius,  like  Dorymyr- 
mex,  shows  a  beginning  of  cupolar  pleating:  only  the  margins 
of  each  quadrant  are  interrupted  by  phragmata.  The  subdeltoid 
outline  of  the  plical  cross  section  and  the  short  dense  evenly- 
distributed  pile  of  the  cupolar  face  and  portal,  characteristic  of 
both  Dorymyrmex  and  Iridomyrmex,  are  already  fully  developed 
in  Forelius. 

Histologically,  the  picture  presented  by  the  longitudinal 
muscles  is  puzzling  (Fig.  36).  The  most  conspicuous  fibers 
(l.m.f)  insert  on  the  underside  of  the  quadrants  outside  the 
circular  muscles,  bend  posteriorly  around  the  circumeupolar  fold 
of  the  crop,  and  fan  out  anteriorly  over  the  crop.  These  fibers 
would  seem  to  represent  a  newly  captured  component  of  the 
proventricular  musculature,  possibly  representing  crop  fibers 
that  have  secondarily  inserted  on  the  cupola.  A  single  fiber  (see 
t,  Fig.  36)  is  shown  as  a  remnant  of  l.m.l.  A  question  mark  has 
been  used  to  denote  this  fiber,  since  its  presence  is  not  of  general 
occurrence,  and  I  have,  in  fact,  seen  it  only  as  a  single  fiber  in 
one  of  the  three  proventriculi  sectioned  longitudinally  (all  were 
workers  of  the  same  nest  series).  This  variation  in  the  presence 
of  l.m.l  points  to  Forelius  as  an  evolutionary  stage  in  the 
Dorymyrmex-Iridomyrmex  line  at  which  l.m.l  has  become 
totally   superfluous   and   is    disappearing.    Longitudinal   fibers, 


EISNER:   ANT  PROVENTRICULUS  463 

similar  in  position  to  l.m.3  of  previous  proventriculi  are  present 
in  Forelius. 

Although  its  general  structural  affinities  to  Dorymyrmex  sug- 
gest that  the  Forelius  proventriculus  functions  in  much  the  same 
way,  there  remains  to  be  found  a  fully  satisfactory  explanation 
of  the  function  of  the  unique  longitudinal  muscles  (l.m.?)  of 
Forelius.  In  view  of  their  insertion  on  the  underside  of  the 
quadrants,  their  obvious  function  would  appear  to  be  quadrant 
disengagement  and  portal  widening.  The  general  rigidity  of 
the  cupola  (evidenced  again  in  this  genus  by  resistance  to  dis- 
placement when  a  glass  needle  is  inserted  through  the  portal) 
would,  of  course,  preclude  anything  but  the  narrowest  margin 
of  cupolar  mobility,  and  the  most  that  the  muscles  can  accom- 
plish is  a  minimal  distention  of  the  portal  slits  (in  much  the  same 
way  as  in  Tapinoma).  But  why  has  portal  distention  become  a 
necessity  in  Forelius  when  it  is  obviously  superfluous  in  the 
basically  similar  proventriculi  of  Dorymyrmex  and  Iridomyr- 
mexl  The  answer  lies  in  the  relatively  larger  size  of  the  Forelius 
bulb,  the  midistended  portal  of  which  offers  an  insufficient  intake 
orifice  during  bulbar  expansion.  One  may  ask  why  Forelius  did 
not  retain  a  fully  developed  set  of  l.m.l  to  accomplish  portal  dis- 
tention instead  of  acquiring  a  completely  new  set  of  muscles,  but 
careful  examination  of  Figure  36  shows  that  l.m.l,  due  to  its 
adaxial  position,  would  be  ill-suited  to  accomplish  quadrant 
retraction  even  if  strongly  developed. 

The  following  two  genera  {Conomyrma  and  Techno  my  rmex) 
have  much  in  common  with  the  Forelius-Dorymyrmex-Irido- 
myrmex  line,  but  certain  unique  characteristics  of  their  own 
suggest  their  phyletic  divergence  from  this  series. 

Conomyrma  Forel 

Species  examined:  C.  thoracica*  Santschi 

Conomyrma,  in  common  with  Forelius,  Dorymyrmex  and 
Iridomyrmex,  shows  a  partial  envelopment  of  the  bulb  by  the 
cupola,  the  degree  of  involvement  being  intermediate  between  that 
of  Forelius  and  Dorymyrmex  (Figs.  33,  46,  47).  The  cupolar 
cuticle  bears  short  dense  pile,  and  the  bulbar  plicae  are  sub- 
deltoid in  cross  section  (Figs.  37,  38,  39).  L.m.l  fibers  are 
totally  lacking,  and  there  are  present  only  those  longitudinal 


464  BULLETIN  :    MUSEUM  OF  COMPARATIVE  ZOOLOGY 

fibers  (l.m.3?)  that  maintain  the  circumcupolar  fold  of  the  crop. 

Conomyrma  differs  from  the  Forelius-Dorymyrmex-Iridomyr- 
mex  series  in  that  it  has  no  phragmata  to  interrupt  the  strongly 
convex,  evenly  sclerotized  surfaces  of  the  quadrants.  The  four 
convex  quadrants,  separated  by  the  recessed  lines  at  the  arms  of 
the  portal,  produce  a  four-lobecl  or  somewhat  clover-leafed 
pattern  in  frontal  view   (Fig.  47). 

The  "yielding  lines"  in  the  cupola,  needed  to  allow  bulbar 
contraction,  coincide  with  the  arms  of  the  cruciform  portal. 
The  elastic  arch  formed  by  each  quadrant  confers  the  necessary 
flexibility  to  allow  recession  at  the  "yielding  lines"  during 
bulbar  contraction.  The  placement  of  the  "yielding  lines"  at 
the  portal  slits  also  ensures  a  tight  closure  of  the  latter  during 
contraction  of  the  bulb,  and  this  closure  acts  as  an  efficient 
valve  opposing  backflow.  Thus,  by  means  of  a  relatively  simple 
variation  in  the  cupolar  plan,  the  Conomyrma  proventriculus 
has  avoided  the  development  of  phragmata  and  the  ensuing  dif- 
ficulties that  had  to  be  met  with  in  Iridomyrmex  by  the  acquisi- 
tion of  a  secondary  valve-seal  in  the  bulb. 

TECHNOMYRMEX   Mayr 

Species  examined:  T.  detorquens*  (Walker)  (=albipes  F. 
Smith). 

This  proventriculus  (Figs.  48,  49)  is  so  similar  to  that  of 
Conomyrma  in  the  major  features  of  its  framework  that  one  is 
hound  to  assume  that  it  functions  in  identical  fashion. 

Technomyrmex,  like  Conomyrma,  has  acquired  arched  quad- 
rants as  a  means  of  conveying  flexibility  to  the  cupola ;  the  arch- 
ing is  more  pronounced  than  in  Conomyrma  and  affords  a  dis- 
tinguishing character. 

Emery  (1888)  and  Forel  (1878)  have  already  pointed  to 
the  unique  sculpturing  manifested  by  the  Technomyrmex  cupola. 
In  T.  detorquens  this  sculpturing  takes  the  form  of  a  reticulum 
of  hexagonal  units  (Fig.  49),  raised  on  the  underside  of  the 
cupola.  My  preparations  suggest  (although  not  with  certainty) 
that  the  hexagonal  units  delimit  the  areas  of  cuticular  deposition 
of  the  individual  underlying  epithelial  cells.  Emery  interprets 
the  reticulum,  not  as  a  surface  sculpturing,  but  as  an  intra- 
cuticular  labyrinth ;  it  is  likely  that  he  was  led  to  an  erroneous 


EISNER  :   ANT   PROVENTRICULUS  465 

interpretation  by  the  obliquity  of  his  seetions. 

Technomyrmex  differs  from  Conomyrma,  Forelius,  Dorymyr- 
mex,  and  Iridomyrmex  in  that  the  bulbar  plicae  are  not  subdel- 
toid, but  C-shaped  in  cross  section  (Fig.  49).  This  feature,  the 
unique  type  of  cupolar  sculpturing,  and  also  divergent  external 
characters  of  the  whole  ant  that  have  long  been  recognized  by 
taxonomists  (Brown,  W.  L.,  personal  communication)  point  up 
the  possibility  that  the  form  and  function  of  the  Technomyrmex 
proventriculus  may  have  developed  along  an  independent  line. 
In  this  case,  the  proventriculi  of  Technomyrmex  and  Conomyrma 
would  have  to  be  counted  as  a  striking  instance  of  convergent 
evolution. 

Subfamily  FORMICINAE 

Among  the  formicine  genera,  the  proventriculus  falls  far  short 
of  developing  the  heterogeneity  of  types  we  have  seen  to  occur 
in  the  Dolichoderinae.  In  fact,  all  Formicinae  possess  either  one 
or  the  other  of  two  basic  types  of  proventriculi,  with  relatively 
slight  variation,  except  for  the  very  few  known  species,  belong- 
ing to  only  one  or  two  genera,  in  which  the  proventriculus  is  of 
intermediate  character.  The  tAvo  main  types,  w.ith  the  intermedi- 
ates, seem  to  express  a  simple  evolutionary  progression  from  the 
more  generalized  asepalous  type  to  the  advanced  sepalous  type. 
From  among  many  possible  examples,  the  two  described  here  in 
detail  as  representative  of  asepalous  (Notoncus)  and  sepalous 
(Camponotus)  types  were  chosen  because  of  their  relatively  large 
size  and  because  adequately  preserved  material  happened  to  be 
available. 

Asepalous  Formicine  Proventriculus 

Notoncus  Emery 

Species  examined:  N.  ectatommoides*   (Forel). 

The  cuticular  framework  (Fig.  50)  consists  of  cupola  and 
bulb,  both  characterized  by  extreme  sclerotization  and  rigidity. 

The  cupola,  unlike  that  of  any  dolichoderine  proventriculus. 
is  not  hollowed  out,  but  consists  of  a  thick  solid  cuticular  cap 
roofing  the  frontal  aspect  of  the  bulb.   The  face  of  the  cupola  is 


466  BULLETIN  :   MUSEUM  OF  COMPARATIVE  ZOOLOGY 

flattened  in  Notorious  (but  domed  in  many  other  asepalous  formi- 
cine  genera)  and  frames  a  narrow  cruciform  portal.  The  portal 
continues  inward  through  the  cupola  in  the  form  of  a  narrow 
occlusory  tract,  except  for  the  outer  extremities  of  the  arms  of 
the  portal,  each  of  which  is  immediately  adjacent  to  the  upper 
extension  of  its  respective  plicary  canal  (Figs.  53,  55-58).  The 
face  of  the  cupola,  the  cruciform  portal,  and  the  occlusory  tract 
all  bear  short,  densely  approximated  pile,  similar  to  but  longer 
than  that  found  in  the  advanced  dolichoderine  proventriculi. 
The  cruciform  portal  and  occlusory  tract  are  rigidly  braced  by 
the  massive  cupolar  quadrants ;  it  is  impossible  to  pry  open  the 
portal  with  a  glass  needle  without  cracking  the  bulbar  frame- 
work. 

The  bulb  itself  is  marked  externally  by  the  four  prominent 
plicae,  one  at  each  corner.  The  plicae  are  heavily  sclerotized  and 
c-shaped  in  cross  section,  so  that  the  lumen  of  each  one  forms  a 
distinct  plicary  canal  (pi.  en.).  Posteriorly,  the  bulb  merges 
into  the  stomodaeal  valve  in  much  the  same  way  as  in  all  other 
proventriculi,  by  a  posterior  constriction  and  sudden  thinning  of 
the  cuticle. 

The  proventriculus  of  Notoncus,  like  that  of  probably  all  the 
other  asepalous  formicine  genera,  is  peculiar  in  that  it  does  not 
intrude  into  the  crop  in  dolichoderine  fashion,  but  is  actually 
prevented  from  such  intrusion  by  a  constriction  of  the  crop 
immediately  in  front  of  the  cupola  (precupolar  constriction; 
Figs.  53,  54,  precp.  const.). 

Histologically,  Notoncus  has  undergone  some  striking  innova- 
tions (Figs.  53,  55-58).  The  circular  muscles  are  most  strongly 
developed  around  the  bulb,  and  at  this  level  they  do  not  differ 
significantly  in  their  arrangement  from  those  of  previously  dis- 
cussed proventriculi :  the  innermost  fibers  insert  along  the  plicae, 
while  the  peripheral  fibers  envelop  the  bulb  without  cuticulav 
attachments.  Anteriorly,  the  circular  muscles  extend  past  the 
cupola  to  form  a  relatively  strong  sphincter  surrounding  the 
precupolar  constriction  of  the  crop.  In  this  arrangement  the 
Notoncus  proventriculus  differs  from  all  previously  discussed 
proventriculi,  in  which,  it  will  be  recalled,  the  strongly  developed 
circular  musculature  terminates  abruptly  at  the  anterior  ex- 
tremity of  the  bulb,  whence  it  continues  as  a  loose  network  of 
fibers  over  the  crop. 


EISNER:  ANT  PROVENTRICULUS  467 

The  principal  group  of  longitudinal  muscles  (Fig.  53)  1 
consider,  on  the  basis  of  their  position  inside  the  circular 
muscles,  as  homologues  of  l.m.l  of  previous  proventriculi.  These 
fibers  originate  on  the  interplicary  cuticle  of  the  bulb  and  extend 
anteriorly  to  insert,  not  on  the  cupolar  quadrants,  as  in  previous 
proventriculi,  but  on  the  crop  intima  of  the  precupolar  constric- 
tion, in  such  a  way  as  to  act  as  antagonists  to  the  sphincter  sur- 
rounding the  constriction  (some  fibers  apparently  fail  to  insert 
on  the  cuticle  and  extend  anteriorly  over  the  crop;  see  Fig.  53). 

Outside  the  circular  muscles  there  is  present,  as  usual,  a  second 
rather  weakly  developed  group  of  longitudinal  fibers.  I  am 
tentatively  homologizing  these  with  l.m.3  of  previous  proven- 
triculi, although  their  anterior  insertion  on  the  crop  intima  could 
not  be  verified  with  certainty  in  Notoncus. 

Thus  we  see  that  the  most  important  modifications  of  the 
musculature  of  the  asepalous  formicine  proventriculus  are  cor- 
related, on  the  one  hand,  with  the  loss  of  portal  mobility,  and 
on  the  other  with  the  acquisition  of  the  precupolar  constriction. 
The  development  of  a  rigid  immobile  portal  eliminated  the  need 
for  longitudinal  muscles  of  the  kind  needed  for  quadrant  dis- 
engagement. The  muscles  were  not  lost,  however,  as  occurred  in 
the  higher  dolichoderines  with  similarly  immobile  portals ;  a  shift 
of  their  anterior  insertion  engaged  them  instead  with  the  opera- 
tion of  the  precupolar  constriction  of  the  crop. 

In  its  function  as  a  dam,  the  asepalous  formicine  proventricu- 
lus presents  the  same  advantages  as  that  of  the  higher  dolicho- 
derines, inasmuch  as  the  portal  orifice  is  permanently  reduced 
to  a  narrow,  immobile  and  densely  pilose  slit,  rigidly  braced  by 
the  sclerotized  cupola  and  plicae.  Its  damming  function  is 
actually  improved  over  that  of  the  advanced  dolichoderine  pro- 
ventriculus by  the  presence  of  the  occlusory  tract. 

It  is  in  the  pumping  action  of  the  proventriculus,  and  specifi- 
cally in  the  mechanics  of  ingress  past  the  cruciform  portal  and 
occlusory  tract,  that  we  find  in  Notoncus  a  functional  deviation 
from  previous  proventriculi. 

It  will  be  recalled  that  almost  the  entire  occlusory  tract  is 
by-passed  at  its  four  corners  by  an  anterior  extension  of  the 
plicary  canals.  These  four  tips  apparently  constitute  the  princi- 
pal incurrent  pathways,  since  they  represent  the  points  of  least 
resistance  to  inflow.    In  conformity  with  this  functional  plan, 


468  BULLETIN  :   MUSEUM  OF  COMPARATIVE  ZOOLOGY 

the  occlusory  tract  is  densely  pilose,  while  the  canals  have  naked 
walls.  In  this  method  of  ingress,  the  Notorious  proventriculus 
differs  from  the  dolichoderine  proventriculi  with  similarly  im- 
mobile portals.  In  these,  there  are  no  structurally  differentiated 
pathways  of  resistance  through  the  portal ;  resistance  to  inflow, 
and  therefore  rate  of  inflow,  is  generally  distributed  over  the 
entire  portal. 

Following  is  my  interpretation  of  the  pumping  action  of  the 
proventriculus.  As  the  bulb  cavity  collapses  under  muscle  con- 
traction, the  contents  are  forced  back  through  the  cylinder  into 
the  midgut.  The  entire  occlusory  tract  becomes  maximally  oc- 
cluded through  a  tight  engagement  of  its  pilose  lining,  and  thus 
acts  to  bar  backflow  into  the  crop.  Also,  as  the  bulb  starts  its 
contraction,  its  four  plicary  canals  are  sealed  off  by  approxima- 
tion of  their  inner  edges,  perhaps  imperfectly  in  the  posterior 
portion,  but  at  least  completely  enough  to  act  as  an  auxiliary 
valve  to  prevent  most  of  its  contents  from  flowing  back  and  forc- 
ing their  way  through  the  portal  tips. 

As  the  circular  muscles  relax  and  the  bulb  cavity  expands 
due  to  the  elasticity  of  its  cuticular  framework,  the  original 
narrow  orifice  of  the  cruciform  portal  is  restored.  Simultan- 
eously the  plicary  canals  open  again  into  the  bulb  lumen  and 
communicate  the  bulbar  suction  to  the  tips  of  the  portal.  Un- 
doubtedly, some  liquid  is  sucked  in  also  through  the  occlusory 
tract,  but  this  portion  is  so  extensive  and  densely  covered  with 
hairs  that  traffic  through  it  must  be  minor  as  compared  to  that 
through  the  lateral  canal  system. 

What  is  the  function  of  the  precupolar  constriction?  If  we 
follow  the  basic  assumption  that  the  longitudinal  muscles  con- 
tract alternately  with  the  circular  muscles,  it  is  apparent  that 
the  constriction  opens  and  the  cupola  is  uncovered  to  project 
freely  into  the  crop  just  at  the  time  when  bulb  expansion  has 
initiated  fluid  inflow  through  the  portal.  Thus,  the  opening 
of  the  constriction  acts  as  a  pump  in  itself,  inasmuch  as  it 
assures  the  transfer  of  crop  fluid  to  the  immediately  antecupolar 
lumen  of  the  crop,  and  this  function  is  probably  especially  im- 
portant when  the  crop  contains  only  small  amounts  of  fluid.  An 
additional  function  of  the  precupolar  constriction  is  suggested 
below,  on  page  480.

MELOPHORES   Lubbock

The  outstanding  peculiarity  of  Melophorus  is  to  be  found  in 
the  cupola  (Fig.  52),  the  face  of  which  is  slightly  depressed  in 
the  center  and  protuberant  at  its  four  corners.  Otherwise,  both 
in  its  cuticular  framework  and  arrangement  of  the  muscles 
(Figs.  59-61),  the  proventriculus  does  not  differ  grossly  from 
Notorious.

Species  examined:   D.  hiekmani  (Clark). 

The  proventriculi  of  these  genera  (Figs.  51,  64,  65)  resemble 
one  another  on  the  basis  of  the  strongly  convex  shape  of  the 
cupola.  Diodontolepis,  which  has  not  been  illustrated  herein, 
bears  very  close  resemblance  to  Anoplolepis.  Histological^,  only 
Acropyya  (Figs.  62,  63)  was  examined,  and  except  for  minor 
structural  peculiarities,  such  as  the  extreme  thickness  of  the 
plical  walls,  there  were  found  no  specializations  in  the  arrange- 
ment of  the  muscularis  to  suggest  a  functional  deviation  from 
Notoncus.  All  these  genera  have  a  precupolar  constriction  like 
Notorious.

species  revealed  a  distinctly  peculiar  proventriculus  (Fig.  66), 
unique  among  those  of  asepalous  formicines  in  the  flattened  and 
cruciform  aspect  of  the  cupola,  and  in  the  elongate  and  pos- 
teriorly tapering  shape  of  the  bulh.  (Histologically  preserved 
specimens  of  this  genus  have  recently  been  collected  by  Dr.  E.  0.

CamPONOTTIS   Mayr 

Species  examined:  C.  vicinus*  Mayr,  C.  americanus*  Mayr,  C. 
herculednus  (Linnaeus). 

In  the  eamponotine  proventriculus  (Figs.  67,  68,  70-74),  the 
obvious  distinctive  character,  here  met  for  the  first  time,  is  a 
long  anterior  extension  called  the  calyx,  consisting  of  four 
heavily  sclerotized  strap-like  cuticular  arms,  or  sepals  (sep.), 
extending  anteriorly  from  the  bulb  to  capture  part  of  the  pos- 
terior wall  of  the  crop.  (Sexual  dimorphism  is  manifested  in  all 
sepalous  proventriculi  by  the  slightly  longer  calyx  in  the 
female.) 

The  sepals  may  be  thought  of  as  the  anterior  drawn-out  bulbar 
plicae  of  an  asepalous  precursor,  that  have  carried  along  in  their 
extension  the  four  corners  of  the  cupola  with  their  enclosed 
portal  tips.  Each  sepal  is  seen  to  contain  a  cylindrical  canal,  the 
sepal  canal  (sep.  en.)  (continuous  posteriorly  with  the  plicary 
canal  of  the  bulb),  that  communicates  along  its  entire  length 
with  the  lumen  of  the  calyx  through  a  narrow  and  densely 
pilose  longitudinal  cleft  (pt.)  representing  an  extended  arm  of 
the  cruciform  portal.  On  their  luminal  surface,  the  sepals  are 
covered  with  dense  short  pile  (Fig.  71)  similar  to  that  lining 
the  cupolar  face  of  asepalous  formicine  proventriculi.  The 
sepals  themselves  are  joined  by  means  of  membranous  sheets  of 
inter sepalary  cuticle  (intersep.),  continuous  with  and  of  the 
same  texture  as  the  intima  of  the  crop  wall  proper. 


EISNER:  ANT  PROVENTRICULUS  471 

Posteriorly,  the  sepals  curve  together  and  fuse  medially  at 
the  level  of  the  occlusory  tract.  In  the  structure  of  the  occlusory 
tract  and  bulb,  Camponotus  does  not  differ  grossly  from  asepal- 
ous  proventriculi,  and  the  rigid  c-shaped  plicae  are  again  so 
constituted  that  the  canals  they  enclose  merge  with  the  bulb 
lumen  by  way  of  a  zone  of  constriction  that  can  be  sealed  off 
during  bulb  compression  (Fig.  74). 

Only  relatively  minor  changes  have  occurred  in  the  muscularis 
(Figs.  70-74).  The  l.m.l  fibers  are  seen  to  originate  on  the  inter- 
plicary  cuticle  of  the  bulb,  and  extend  anteriorly  past  the  oc- 
clusory tract,  at  which  point  the  inner  fibers  become  inserted  on 
the  intersepalary  cuticle,  while  the  few  remaining  outer  fibers 
continue  anteriorly  without  cuticular  attachments  past  the  calyx 
and  over  the  crop.  Attention  is  called  to  the  inward  fold  of  the 
intersepalary  cuticle  at  the  bottom  of  the  calyx  (Fig.  70,  a),  and 
into  which  insert  the  l.m.l  fibers.  This  fold  is  undoubtedly  all 
that  remains  in  this  proventriculus  of  the  precupolar  constriction 
of  an  asepalous  ancestor. 

Outside  the  circular  muscles,  a  few  scattered  longitudinal 
fibers  extend  from  crop  to  midgut  (Fig.  70,  ?),  apparently  by- 
passing the  proventriculus  without  cuticular  attachments.  Prob- 
ably these  fibers  contain  only  the  usual  crop-to-midgut  fibers, 
although  it  is  possible  that  they  are  joined  by  homologues  of 
l.m.3  of  previous  proventriculi,  that  have  here  become  detached 
from  the  cuticle.  In  other  sepalous  formicine  genera  (see  For- 
mica next  below)  the  muscles  differ  in  their  arrangement. 

In  its  action  as  a  pump,  this  proventriculus  remains  essentially 
the  same  as  its  asepalous  antecedent.  The  principal  difference 
between  the  two  types  lies,  of  course,  in  the  sepalary  develop- 
ment and  its  functional  consequences.  In  asepalous  formicine 
proventriculi,  the  presence  of  an  occlusory  tract  —  although  a 
distinct  asset  to  the  function  of  the  proventriculus  as  a  dam  — 
considerably  restricts  the  portal  area  available  for  bulbar  intake. 
Only  the  outermost  tips  of  the  portal,  being  immediately  ad- 
jacent to  the  anterior  extensions  of  the  four  plicary  canals  that 
by-pass  the  occlusory  tract,  remain  as  pathways  for  fluid  ingress. 
Camponotus  and  the  other  sepalous  formicines  have  successfully 
exploited  a  means  of  increasing  the  bulbar  intake  area  by  extend- 
ing, in  the  form  of  the  calyx,  both  the  plicary  canals  and  their 
associated  portal  tips.   Thus,  the  calyx  is  to  be  regarded,  not  as 


472  BULLETIN  :    MUSEUM  OF  COMPARATIVE  ZOOLOGY 

au  adjunct  to  the  damming  function  of  the  proventriculus,  but 
as  a  further  refinement  of  the  proventriculus  as  a  pump.  The 
damming  potential  has,  however,  been  retained,  since  increase  in 
portal  area  is  accomplished  without  widening  the  portal  at  any 
point. 

During  bulb  contraction,  when  fluid  is  being  evacuated  from 
the  bulb  through  the  stomodaeal  valve,  backflow  through  the 
occlusory  tract  is  prevented  by  the  tight  engagement  of  its  oppos- 
ing pilose  linings.  Simultaneously,  the  potential  backfloAV  route 
through  the  plicary  and  sepalary  canals  is  closed  (or  nearly 
closed )  by  the  meeting  of  the  edges  of  the  grooves  through  which 
canals  and  bulbar  lumen  communicate.  When  the  bulb  recovers 
by  means  of  elastic  expansion,  the  grooves  are  reopened,  and 
the  lumen  again  communicates  with  the  canals,  initiating  a  new 
inflow  through  the  sepalary  portal  slits.  As  in  the  asepalous 
formicines,  it  seems  that  a  small  amount  of  fluid  must  also  enter 
directly  through  the  occlusory  tract  at  the  stage  of  expansion; 
however,  the  length,  narrowness,  dense  vestiture  and  extremely 
restricted  mobility  of  the  four  clefts  forming  the  tract  surely 
reduce  such  inflow  to  a  negligible  quantity,  especially  when  one 
considers  the  opportunity  for  fluid  ingress  offered  by  the  portal- 
plus-canals. 

Emery  (1888)  believed  the  calyx  to  function  exclusively  as  a 
valve  that,  by  sustained  occlusion,  acts  to  relieve  the  proventricu- 
lus of  fluid  pressure  from  the  crop.  He  disregarded  the  possi- 
bility that  the  principal  intake  system  of  the  bulb  might  be 
routed  through  the  sepals.  He  believed  that  the  pilose  lining 
of  the  portal  clefts  actually  seals  off  the  sepal  canals  from  the 
calyx  cavity:  "Die  Kinne  wird  gegen  das  Lumen  des  Kelches 
durch  das  Ineinandergreifen  der  die  Flugel  besetzenden  Har- 
chen  verschlossen."  Accordingly,  he  was  inclined  to  treat  the 
sepals  as  relatively  unimportant  structures.  Subsequent  workers, 
including  Forbes  ('38),  have  observed  that  the  canals  really 
open  into  the  lumen,  but  not  until  recently  (Eisner  and  Wilson 
'52)  has  the  possibility  been  considered  that  they  might  serve 
to  conduct  fluid  past  the  occlusory  tract. 

Brief  mention  should  be  made  at  this  point  of  an  incidental, 
I  nit  probably  significant  function  of  the  calyx.  It  is  likely  that 
during  bulbar  activity  the  calyx  undergoes  pulsations  synchron- 
ous with  those  of  the  bulb,  being  alternately  constricted  by  its 


EISNER:   ANT  PROVENTRICULUS  47o 

circular  muscles  and  expanded  by  the  elastic  spring-like  action 
of  the  sepals.  During  calyx  expansion,  crop  fluid  tends  to  be 
drawn  into  the  calyx  lumen,  thereby  assuring  an  adequate  sup- 
ply of  the  bulb  just  at  the  time  when  bulb  expansion  initiates 
fluid  intake  through  the  sepalar-portal  arrangement.  Thus,  while 
increase  of  intake  area  was  the  principal  evolutionary  justifica- 
tion for  the  appearance  of  the  calyx,  it  seems  that  it  came  to 
function  also  as  an  analogue  of  the  precupolar  constriction  of 
asepalous  proventriculi. 

It  is  doubtful  that  the  l.m.l  fibers  play  any  significant  con- 
tributory role  in  the  expansion  of  the  calyx,  since  they  insert, 
not  on  the  sepals  themselves,  but  on  the  loosely  folded  and 
flaccid  intersepalary  cuticle.  Furthermore,  in  other  sepalous 
formicines  (Formica),  the  similar  structure  of  which  suggests 
no  great  functional  divergence  from  Camponotus,  l.m.l  has  been 
lost  entirely.  I  regard  l.m.l  in  Camponotus  as  a  mere  remnant 
persisting  from  an  asepalous  antecedent  in  which  the  function 
of  l.m.l  was,  as  in  Notoncus,  the  dilation  of  the  precupolar  con- 
striction. 

FORMICA    Linnaeus 

Species  examined:  F.  sp.*  (fusca  group),  F.  subnuda  Emery 
(sanguinea  group). 

Aside  from  obvious  but  relatively  minor  differences  in  the 
shape  of  the  bulb  and  calyx,  Formica  (Figs.  69,  75,  100-103)  dif- 
fers significantly  from  Camponotus  only  in  the  arrangement  of 
the  longitudinal  muscles  (compare  Figs.  70  and  75).  L.m.l 
is  entirely  absent.  There  is  present,  outside  the  circular  muscles, 
a  group  of  longitudinal  fibers  that  insert  anteriorly  on  the  crop 
intima  so  as  to  maintain  a  circumsepalar  fold  of  the  crop  (Fig. 
75)  ;  I  am  tentatively  homologizing  these  fibers  with  l.m.3  of 
previous  proventriculi.  In  Camponotus  (Fig.  70)  no  such  cir- 
cumsepalar fold  was  found,  and  the  scanty  outermost  longitud- 
inal muscles  of  the  proventriculus  extend  from  crop  to  midgut 
without  apparent  cuticular  connections. 

Figures  76-84  illustrate  a  variety  of  the  forms  of  cuticular 
framework  found  among  different  sepalous  formicine  genera,  in- 
cluded here  chiefly  because  of  their  taxonomic  interest.  The 
features  of  each  type  as  known  at  this  time  are  clear  from  the 


474  BULLETIN  :   MUSEUM  OF  COMPARATIVE  ZOOLOGY 

figures,  and  the  individual  cases  require  no  discussion.  (In 
Myrmecocystus  (Fig.  79)  the  tips  of  the  sepals  curve  outward 
only  in  the  worker;  in  the  female  they  are  straight.) 

Proventriculi  were  examined  for  a  number  of  additional  gen- 
era, but  since  each  of  these  closely  resembles  one  of  the  genera 
figured,  it  will  suffice  here  merely  to  list  the  correspondences. 
Gigantiops  destructor  (Fabricius),  Dendromyrmex  chartifex  (F. 
Smith),  Opisthopsis  haddoni  Emery,  and  Polyergus  breviceps 
Emery  resemble  Formica.  Polyrachis  dives  (F.  Smith)  is  similar 
to  Camponotus.  Pseudolasius  mayri  Emery  closely  resembles 
Lasius. 

Although  such  characters  as  the  shape  of  bulb  and  plicae 
and  length  of  the  sepals  may  in  themselves  be  valuable  phyletic 
indicators,  it  is  hoped  that  the  internal  evolutionary  relation- 
ships of  this  series  will  be  further  clarified  by  future  work,  and 
especially  by  a  comparative  histological  analysis  of  the  longi- 
tudinal musculature.  The  possibility  should  not  be  lightly  dis- 
missed that  a  major  phylogenetic  divergence  may  be  outlined 
by  the  presence  or  absence  of  l.m.l,  as  exemplified  in  this  study 
by  Camponotus  and  Formica  respectively. 

Proventriculi  with  Incipient  Sepals 

ClADOMYRMA  Wheeler 

Species  examined:  C.  hewitti  Wheeler. 

Only  two  dried  specimens,  a  queen  and  a  worker,  probably 
lit'stmates,  were  available  for  study  of  this  very  rare  genus.  The 
proventriculus  of  the  queen  (Fig.  85)  shows  an  incipient  but 
nevertheless  distinctly  typical  calyx,  and  on  this  basis  Clado- 
myrma  would  seem  to  represent  a  survivor  of  the  ancestral  stock 
that  gave  rise  to  the  higher  sepalous  formicines.  Sexual  di- 
morphism is  strikingly  exemplified  in  this  genus  by  the  com- 
plete absence  of  a  calyx  in  the  worker,  the  proventriculus  being 
endowed  with  a  typical  asepalous  cupola. 

MyeMECORHYNCHUS    Andre 

Species  examined:  M.  emery i  Andre.* 

Although  distinctly  suggestive  of  an  incipient  sepalar  condi- 
tion (Fig.  86),  other  peculiarities  of  the  proventriculus,  as  well 


EISNER:   ANT  PROVENTBICULUS  47.") 

as  characteristics  of  the  whole  ant  (W.  L.  Brown,  and  E.  0. 
Wilson,  personal  communication),  point  to  the  possibility  that 
Myrmecorhynckus  may  stand  apart  as  an  evolutionary  offshoot, 
having  acquired  its  sepal-like  structures  by  convergence. 

The  bulb  is  more  capacious  than  usual  (Fig.  89),  and  the 
occlusory  tract  is  not  reduced  to  a  narrow  impassable  cleft  as  in 
other  formicines,  but  is  seen  to  he  held  agape  (Fig.  88),  sug- 
gesting that  bulbar  intake  is  generally  distributed  over  the  entire 
portal  and  occlusory  tract  instead  of  just  at  the  tips.  Most  prob- 
ably, this  widening  of  the  occlusory  tract  developed  in  response 
to  the  increase  in  bulbar  capacity.  The  cruciform  portal  also 
differs  from  other  formicines  in  that  it  lacks  the  usual  pilose 
vestiture. 

In  its  musculature,  Myrmecorhynckus  is  like  Notoncus.  The 
precupolar  constriction  and  l.ni.l  are  well  developed  and  prob- 
ably still  functional. 

PONEROID  COMPLEX 

Only  very  few  representatives  of  this  complex,  including  one 
or  two  genera  of  each  of  the  four  major  subfamilies  currently 
recognized  (Brown  '54),  were  examined  for  the  present  study. 
In  part  this  was  due  to  the  lack  of  properly  preserved  material, 
an  especially  unfortunate  handicap  here  since  the  relative  uni- 
formity of  the  cuticular  framework  of  the  poneroid  proventricu- 
lus  forces  one  to  turn  to  the  arrangement  of  the  muscles  in  the 
search  for  phyletic  indicators.  The  aberrant  subfamily  Leptanil- 
linae  could  not  be  studied  at  all ;  I  did  not  succeed  in  recovering 
a  proventriculus  from  the  single  dried  specimen  that  was  avail- 
able to  me. 

Subfamily  PONERINAE 

OdONTOMACHUS    Latreille 

Species  examined:   0.  haematoda*  (Linnaeus),  or  near. 

In  its  principal  features  (Fig.  90),  the  proventricular  frame- 
work conforms  to  the  general  plan  of  Myrmecia.  The  bulb  is 
elongate  and  posteriorly  tapering.  Only  the  interplicary  plates 
are  somewhat  sclerotized;  the  plicae  themselves  are  thin  and 
flaccid.    The  cupolar  quadrants  are  globose,  and  diverge  from 


47(i  BULLETIN  :   MUSEUM  OP  COMPARATIVE  ZOOLOGY 

one  another,  framing  a  widely  gaping  cruciform  portal.  The 
presence  of  l.m.l  and  l.m.3,  similarly  arranged  as  in  Myrmecia, 
could  be  determined  with  certainty.  The  apparent  absence  of 
l.m.2  is  not  to  be  taken  as  conclusive,  since  my  preparations  were 
inadequate. 

Both  in  its  pumping  action  and  damming  potential,  the  pro- 
ventriculus  of  Odontomachus  probably  resembles  that  of  Myr- 
mecia. 

AMBLYOPONE    Erichson 

Species  examined:   A.  australis*  Erichson. 

This  proventriculus  (Fig.  91)  is  strikingly  unique  among  those 
of  ants,  and  possibly  all  other  Hymenoptera,  in  that  it  deviates 
from  the  basic  quadripartite  plan.  The  cupolar  quadrants, 
portal  arms,  plicae,  and  interplicary  plates  are  six  in  number, 
instead  of  the  usual  four.  Except  for  this  remarkable  feature, 
Amblyopone  does  not  differ  greatly  from  Odontomachus.  The 
cupolar  quadrants  are  more  closely  approximated,  and  do  not 
diverge  apically  as  in  Odontomachus.  The  plicae  are  mem- 
branous, and  the  entire  proventriculus  is  weakly  sclerotized  and 
flaccid.  The  material  available  was  poorly  preserved,  rendering 
impossible  an  exact  delineation  of  the  longitudinal  musculature. 
The  l.m.l  fibers  are  grouped  into  six  separate  bundles  instead  of 
the  usual  four,  each  bundle  following  the  course  of  its  corre- 
sponding interplicary  plate. 

The  structural  peculiarities  of  Amblyopone  do  not  suggest 
any  major  functional  deviations.  Its  function,  like  that  of 
Odontomachus,  is  probably  similar  to  that  of  Myrmecia. 

Amblyopone  is  generally  agreed  to  be  one  of  the  most  primitive 
of  all  living  ants.  The  distinct  peculiarities  of  its  proventriculus 
point  up  the  possibility  that  Amblyopone  may  actually  be  more 
highly  specialized  than  previously  suspected. 

Subfamily  CERAPACHYINAE 
PHYRACACES    Emery 

Species  examined:    P.  dumbletoni  Wilson. 

Although  distinctive  in  its  barrel-shaped  bulb   (Fig.  92),  the 


EISNER  :    ANT   PROVENTRICULUS  477 

proventriculus  of  Phyracaces  conforms  to  the  structural  plan  of 
Myrmecia,  and  presumably  functions  in  a  similar  way.  The 
presence  of  l.m.l  and  l.m.3,  arranged  as  in  Myrmecia,  was  deter- 
mined with  certainty,  but  there  remains  some  doubt  about  the 
apparent  absence  of  l.m.2. 

Subfamily  MYRMICINAE 

POGONOMYEMEX   Mayr 

Species  examined :  P .  occidentalism  (Cresson). 

The  cutieular  framework  (Fig.  95)  consists  of  an  elongate, 
extremely  flaccid  and  funnel-shaped  ''bulb,"  devoid  of  a  cupola, 
merging  anteriorly  with  the  crop  through  a  gradual  expansion 
of  its  lumen.  Although  the  Avail  of  the  bulb  is  produced  into 
four  inward  folds,  vaguely  delimiting  plicary  and  interplicary 
regions  (Fig.  96),  there  are  no  textural  differences  between  these 
regions,  the  cuticle  being  evenly  membranous  throughout.  The 
circular  muscles  are  strongly  developed  as  usual,  but  have  lost 
all  cuticular  connection.  The  exact  course  and  homologies  of  the 
longitudinal  muscles  could  not  be  determined.  The  principal 
group  of  fibers,  extending  as  four  bundles  along  the  inward  folds 
of  the  bulbar  cuticle,  are  strongly  suggestive  of  l.m.l. 

It  is  difficult  to  explain  the  functional  implications  of  the 
obviously  degenerate  condition  of  this  proventriculus.  The  loss 
of  an  anterior  valve-seal,  elsewhere  provided  by  the  cupola,  and 
the  loosely-folded  membranous  condition  of  the  bulbar  cuticle, 
speak  for  a  radical  departure  from  the  usual  fluid  pumping 
action.  It  may  well  be  that  this  type  of  proventriculus  has  be- 
come modified  to  yield  to  the  passage  of  solid  matter,  forced 
through  the  bulb  under  muscular  pressure.  This  possibility 
deserves  further  attention,  especially  since  the  myrmicines  are 
known  for  their  unusual  feeding  habits,  several  genera  commonly 
partaking  of  seeds  and  other  vegetable  material. 

The  structural  divergences  of  the  Pogonomyrmex  proventric- 
ulus would  not  seem  to  have  reduced  its  capacity  as  a  dam,  since 
the  membranous  bulb  is  readily  occlusible  under  muscular  con- 
traction. 

Forel  (1878)  and  Emery  (1888)  called  attention  to  the  highly 
aberrant  proventriculus  of  the  myrmicine  tribe  Cephalotini.  This 
proventriculus  has  re-acquired  a  cupola,  in  the  form  of  a  rigid 


478  BULLETIN:   MUSEUM  OF  COMPARATIVE  ZOOLOGY 

and  elaborately  ornamented  umbrella,  that  abuts  a  typical  funnel- 
shaped  and  membranous  myrmicine  "bulb."  The  functional  sig- 
nificance of  this  unusual  cupolar  development  is  obscure  at  pres- 
ent. 

Hylomyema    Forel

This  proventriculus  is  identical  in  all  major  respects  to  Pogo- 
nomyrmex. 

Subfamily  DORYLINAE 

ECITON    Latreille 

Species  examined:  E.  hamatum*  (Fabricius). 

This  proventriculus  (Fig.  93),  although  closely  resembling 
that  of  Pogonomyrmcx,  appears  to  have  progressed  even  further 
in  its  degeneration,  the  folding  of  the  bulbar  cuticle  being  com- 
pletely randomized  and  irregular  (Fig.  94).  This  proventriculus 
is,  in  fact,  nothing  but  a  stomodaeal  valve,  preceded  by  a  mus- 
eularly  maintained  constriction  of  the  posterior  wall  of  the  crop. 

The  same  functional  speculations  advanced  for  Pogonomyrmex 
apply  to  Eciton,  except  that  the  latter  is  wholly  predaceous. 

THE  STOMODAEAL  VALVE 

Except  in  Myrmeeia,  where  it  was  described  in  considerable 
detail,  no  emphasis  has  been  granted  to  the  stomodaeal  valve 
in  the  various,  other  proventriculi.  The  valve  is,  in  fact,  the 
most  uniform  constituent  of  the  ant  proventriculus,  and  the  only 
structural  modifications  that  seem  to  have  functional  overtones 
occur  in  the  degree  of  development  of  the  muscular  sphincter 
that  surrounds  the  neck  of  the  valve  at  the  point  where  it 
pierces  the  midgut. 

In  Myrmeeia,  as  well  as  in  all  other  generalized  proventriculi 
with  divergent  cupolar  quadrants  and  a  mobile  portal  (pseudo- 
myrmecines,  ponerines,  and  cerapachyines),  the  sphincter  is 
strongly  developed,  and  probably  serves  in  maintaining  an  occlu- 
sion of  the  neck  of  the  valve  when  the  resting  proventriculus 
prevails  in  its  function  as  a  dam.   In  all  the  higher  dolichoderines 


EISNER:  ANT   PROVENTRICULUS  479 

and  formicines,  in  which  proventricular  damming  is  accom- 
plished passively  by  an  elastically  maintained  occlusion  of  the 
cupolar  or  sepalar  portal  arrangement,  the  need  for  sustained 
occlusion  at  the  level  of  the  stomodaeal  valve  has  been  lost,  and 
the  sphincter  surrounding  the  neck  of  the  valve  has  accordingly 
become  reduced,  sometimes  consisting  of  not  more  than  a  single 
layer  of  fibers. 

IDENTITY    OF    THE    "SEKRETSCHICHT"    OF    EMERY 

(1888) 

Emery  granted  some  emphasis  to  the  fact  that  the  cupola  of 
most  dolichoderine  proventriculi  seen  by  him  (Tapinoma,  Tech- 
nomyrmex,  Forelius,  Conomyrma  (=Dorymyrmex  Emery  nee 
Mayr),  Bothriomyrmex  and  Iridomyrmcx)  is  tightly  overlain  by 
a  discrete  layer  or  "membrane"  of  varying  thickness.  Emery 
assumed  that  this  layer,  which  he  called  in  its  different  forms 
Sekretschicht,  SeJcrethautchen,  or  Sekretblattchen,  was  a  deposit 
secreted  by  the  cupolar  epithelium.  He  found  no  such  layer  pres- 
ent in  Azteca,  Liometopum,  Leptomyrmex,  or  tribe  Dolicho- 
derini.  Among  the  formicines,  Emery  found  the  layer  present  in 
Camponotus  ligniperdus,  but  makes  no  mention  of  it  in  the  two 
asepalous  genera  he  examined,  Plcujiolepis  and  Brachymyrmex. 

In  the  histological  preparations  made  for  this  work,  a  dense 
layer,  more  or  less  unevenly  granulose  in  texture  (Fig.  98),  was 
found  covering  the  cupola  or  sepals  of  the  following  genera : 

Doliehoderinae  :  Forelius,  Dorymyrmex,  Iridomyrmex,  Turneria, 
( 'onomyrma,  Teeh nomyrmex. 

Formicinae:  Camponotus,  Formica. 

The  layer  varied  considerably  in  thickness,  even  among  nest- 
mates.  Structurally,  it  showed  considerable  differentiation  from 
genus  to  genus,  particularly  in  texture  and  in  staining  reaction ; 
in  some  cases  the  layer  was  weakly  basophilic,  in  others  totally 
refractory  to  the  stains  used. 

There  wTas  no  trace  of  a  layer  in  Myrmecia,  Pseudomyrmcx, 
Aneuretus,  Tapinoma,  and  members  of  the  poneroid  complex. 
In  Azteca,  Liometopum,  and  Leptomyrmex,  as  well  as  in  all 
genera  of  asepalous  Formicinae  that  were  sectioned  (Notoncus. 
Melophorus,    and    Acropyga),    there    was    present    no    compact 


480  BULLETIN:   MUSEUM  OF  COMPARATIVE  ZOOLOGY 

layer,  but  the  cupolar  hairs  held  some  clustered  particles  in  loose 
irregular  arrangement  (Fig.  99). 

It  is  evident  that  the  degree  of  development  of  the  layer  is 
closely  correlated  with  the  amplitude  of  portal  mobility.  With 
the  notable  exception  of  asepalous  formicines,  a  compact  layer 
is  present  only  in  those  proventriculi  endowed  with  an  immobile 
slit-like  portal.  Given  this  correlation,  my  interpretation  of  the 
"Sekretschicht"  is  that  it  is  most  likely  not  a  secreted  structure, 
but  merely  a  filtration  aggregate  consisting  of  those  small  parti- 
cles that,  having  escaped  the  withholding  action  of  the  infra- 
buccal  chamber  and  the  filtration  devices  within  the  buccal 
cavity,  have  massed  on  the  cupolar  or  sepalar  surfaces,  held  back 
by  the  filtering  guard  hairs  of  the  proventricular  portal. 

There  remains  to  be  explained  the  absence  of  the  layer  in  the 
asepalous  formicines.  The  precupolar  constriction  may  afford 
this  explanation,  considering  its  probable  action  of  sweeping  the 
cupolar  face  repeatedly  during  the  pumping  cycle  (see  under 
Notoncus,  p.  468). 

One  apparent  inconsistency  in  this  hypothesis  is  the  difference 
found  between  Tapinoma  and  Forelius,  despite  the  similar  func- 
tions proposed  for  these  genera  insofar  as  their  damped  portal 
opening  is  concerned.  Tapinoma  sessile  lacked  the  filtrate  layer 
in  my  preparations,  while  my  Forelius  possessed  the  layer  in  a 
well-developed  form.  The  probability  that  the  portal  does  open 
would  at  first  glance  seem  to  render  difficult  the  accumulation 
of  sufficient  filtrate  to  form  a  layer,  but  the  degree  to  which 
this  opening  is  damped  in  these  two  genera  actually  makes  it 
more  surprising  that  Tapinoma  lacks  the  layer  than  it  does  that 
Forelius  has  it. 

As  noted  above,  Emery  found  the  layer  present  in  Tapinoma, 
but  in  a  different  group  of  the  genus,  in  T.  mclanocephalum 
(Fabricius).  Absence  of  the  layer  in  my  Tapinoma  could  be 
taken  as  a  sign  that  my  interpretation  of  proventricular  func- 
tion is  incorrect,  and  that  the  portal  really  opens  more  widely 
than  seems  possible  in  view  of  the  cupolar  rigidity.  However,  the 
structural  qualities  of  the  Tapinoma  proventriculus  lead  me  to 
believe  that  the  lack  of  a  filtrate  layer  in  my  limited  samples  is 
either  a  histological  artifact  or  else  reflects  a  lack  of  particulate 
dietary  constituents  in  these  specimens,  all  drawn  from  a  uni- 
nidal  series. 


EISNER:    ANT   PROVENTRICULUS  481 

PART    III 

DISCUSSION 

One  of  the  organs  long  used  in  ant  classification  is  the  pro- 
ventriculus, a  structure  in  which  major  changes  are  largely 
concordant  with  subfamily,  and  even  with  many  tribal  breaks 
based  primarily  on  other  structural  characters.  It  is  this  con- 
cordance that  renders  proventricular  structure  such  a  valuable 
indicator  of  phylogeny  within  the  ants,  and  at  the  same  time 
affords  a  basis  for  checking  evolutionary  steps  in  proventricular 
modification.  Even  at  the  generic  level,  the  proventriculus  so 
far  as  known  offers  no  serious  contradiction  to  presently  ac- 
cepted classifications,  and  the  deeper  one  probes  into  the  details 
of  musculature  and  other  components,  the  more  new  useful  in- 
formation the  organ  yields  for  the  systematist. 

In  Figure  97,  a  dendrogram  is  based  on  the  structural  rela- 
tionships of  the  known  proventriculi  as  revealed  by  the  present 
study,  and  interpreted  in  the  light  of  the  most  recent  phyletic 
se-hemes.  It  will  be  necessary  to  refer  to  this  figure  in  following 
the  discussion  below. 

The  outstanding  feature  of  the  adult  hymenopterous  digestive 
tract  is  the  crop,  a  stomodaeal  food  reservoir  acquired  in  adapta- 
tion to  the  relatively  discontinuous  feeding  habits  characteristic 
of  these  insects  (Bischoff  '27).  The  proventriculus  is  essentially 
a  structure  accessory  to  the  crop,  and  in  this  capacity  serves 
both  as  a  dam,  capable  of  containing  the  pressure  exerted  by 
the  liquid  crop  contents,  and  as  a  pump,  regulating  the  delivery 
of  fluid  to  the  midgut.  It  consists  of  a  flexible  but  strongly- 
muscled  bulb,  the  pump,  with  intake  and  exhaust  valves  provided 
respectively  by  the  cupolar  portal,  and  the  stomodaeal  valve. 
The  stomodaeal  valve  is  embraced  by  a  sphincter,  the  sustained 
contraction  of  which  presumably  effects  the  dam. 

This  simple  type  of  proventriculus  is  well  suited  to  the  habits 
of  the  solitary  Hymenoptera,  the  crop  of  which  stores  food  for 
its  own  use,  or  at  the  most  for  the  use  of  itself  and  its  mate 
(Given  '54). 

With  the  acquisition  of  social  habits  and  division  of  labor,  the 
burden  of  securing,  transporting  and  transmitting  food  falls 
entirely  upon  a  part  of  the  adult  population.    The  brood,  re- 


482  BULLETIN  :   MUSEUM  OF  COMPARATIVE  ZOOLOGY 

prod uc tives,  and  non-foraging  workers  are  more  or  less  continu- 
ous consumers  of  food,  but  contribute  little  or  nothing  to  the 
larder.  There  thus  arises  a  necessitj'  for  a  storage  system  —  a 
necessity  accentuated  under  unfavorable  environmental  condi- 
tions. Honeybees,  for  instance,  solve  this  storage  problem  by 
means  of  the  comb,  a  communal  storehouse  external  to  their  own 
bodies. 

In  the  ants,  such  storage  facilities  as  exist,  at  least  for  fluids, 
are  usually  limited  to  the  crops  of  the  individual  workers.  The 
storage  of  amounts  of  fluid  far  in  excess  of  the  needs  of  the 
individual  worker,  and  for  protracted  periods  of  time,  places  a 
strain  on  the  arrangements  by  which  damming  depends  upon 
sustained  muscular  contraction  of  the  stomodaeal  valve  sphincter. 
Any  structural  changes  tending  to  relieve  the  load  of  the 
sphincter  are  therefore  at  a  premium,  especially  if  these  changes 
can  shift  the  load  to  a  passive  barrier. 

The  generalized  formicid  pro  vent riculus 

In  the  lower  ants  (Ponerinae,  Cerapachyinae,  Myrmeciinae, 
Pseudomyrmecinae,  and  Aneuretinae)  the  proventriculus  is  simi- 
lar in  all  major  respects  to  that  of  the  other  Hymenoptera  so 
far  studied.  Proventricular  damming  is  probably  maintained 
exclusively  b}*  the  stomodaeal  valve  sphincter,  which  in  these 
ants  is  especially  well  produced.  The  bulb  is  a  flaccid  structure 
with  gaping  portal,  incapable  in  itself  of  plugging  the  crop. 
Damming  is  therefore  a  dynamic,  energy-consuming  process. 
This  basically  inefficient  mechanism  limits  the  full  exploitation 
of  the  social  functions  of  crop  storage  and  regurgitative  feeding. 
Indeed,  recent  work  emphasizes  the  fact  that  in  these  primitive 
ants,  regurgitative  feeding  is  still  in  its  incipient  stages  (Le 
Masne  '53,  Haskins  and  Whelden  '54).  None  of  these  ants  is 
known  to  have  ' '  replete ' '  castes. 

Dolichoderinae  and  ITormicinae 

In  the  advanced  dolichoderines  (tribe  Tapinomini)  and  all 
formicines,  proventricular  damming  no  longer  depends  upon  the 
continuous  muscular  pressure  of  the  stomodaeal  valve  sphincter, 
and  the  sphincter  in  these  subfamilies  is  greatly  reduced  in  size. 


EISNER:  ANT  PROVENTRICULUS  483 

The  damming  function  has  shifted  to  the  reinforced  cupola, 
which  now  forms  a  rigid  shield,  pierced  by  a  narrow,  densely 
pilose  cruciform  slit,  and  capable  by  itself  of  stemming  leakage 
from  the  crop.  Damming  is  therefore  accomplished  passively, 
without  expenditure  of  muscular  energy.  The  evolution  of  the 
proventriculus  in  these  subfamilies  is  the  history  of  the  elaborate 
and  varied  pathways  of  change  along  which  the  proventriculus 
adapted  to  its  new  function  as  a  passive  dam. 

An  early  step  in  the  evolution  of  the  damming  cupola  is 
exemplified  in  the  dolichoderines  by  the  Azteca-Tapinoma  pro- 
ventricular  type,  and  in  the  formicines  by  the  asepalous  type. 
Already  these  proventriculi  have  acquired  the  pilose  portal  slit, 
strongly  braced  by  the  sclerotized  cupola  and  bulbar  plicae,  and 
able  to  hold  back  fluids  when  the  inactive  proventriculus  pre- 
vails in  its  function  as  a  dam.  That  these  remarkably  similar 
refinements  arose  convergently  in  the  dolichoderines  and  formi- 
cines is  attested  by  the  differences  in  the  arrangement  of  the 
longitudinal  muscles  and  by  other  characters. 

The  restriction  both  in  size  of  orifice  and  in  mobility  of  the 
cupolar  portal  arrangement  —  although  a  distinct  asset  to  the 
damming  function  of  the  proventriculus  —  tends  to  render  the 
portal  orifice  inadequate  for  bulbar  intake  during  the  pumping 
cycle.  This  handicap  is  accentuated  in  Azteca  and  the  asepalous 
Formicinae  by  the  interposition,  between  portal  and  bulbar 
lumen,  of  an  occlusory  tract.  In  order  to  reconcile  the  basic 
pumping  action  of  the  bulb  with  the  new  damming  qualities  of 
the  portal,  Azteca  and  Tapinoma  retain  a  limited  range  of 
portal  mobility,  the  quadrants  being  slightly  dislocated  during 
bulbar  intake  under  the  action  of  l.m.l  muscle  fibers.  Dislocation 
is  damped,  with  the  sclerotized  bulbar  plicae  acting  as  spring 
antagonists  to  the  retractor  muscles.  Unlike  those  of  Azteca  and 
Tapinoma,  the  asepalous  formicine  proventriculus  can  accom- 
plish its  pumping  action  without  quadrant  dislocation.  It  has, 
in  fact,  no  muscles  adapted  to  moving  the  quadrants,  the  l.m.l 
fibers  having  shifted  their  insertion  away  from  the  cupola  itself 
to  become  concerned  with  the  operation  of  the  precupolar  con- 
striction of  the  crop.  Bulbar  intake  is  routed  through  the  plicary 
canals,  the  anterior  extensions  of  which  by-pass  the  occlusory 
tract  to  join  the  four  corners  of  the  portal.  This  mechanism  of 
ingress,  although  using  only  a  relatively  small  portion  of  the 


484  BULLETIN  :   MUSEUM  OF  COMPARATIVE  ZOOLOGY 

portal,  must  provide  sufficient  flow  for  the  active  pumping  action 
of  the  organ. 

The  most  advanced  proventricular  types  of  the  dolichoderines 
(Iridomyrmex,  Dorymyrmex,  Conomyrma,  and  Technomyrmex) 
and  formicines  (Camponotus,  and  all  other  sepalous  proventric- 
uli),  although  differing  radically  in  structure,  are  actually  re- 
markably similar  in  their  functional  achievements.  They  retain 
the  narrow  slit-like  portal  attained  by  their  respective  evolu- 
tionary antecedents,  and  are  therefore  similarly  adapted  to  serve 
as  passive  dams.  In  these  proventriculi,  the  need  for  portal 
disengagement  is  completely  eliminated,  and  the  quadrant  re- 
tractors (l.m.l)  are  entirely  absent  or  if  retained,  as  is  the  case 
in  some  sepalous  proventriculi  (Camponotus) ,  they  are  function- 
ally impotent  as  retractors.  The  complete  loss  of  portal  mobility 
is  coincident  with  certain  structural  refinements  designed  to 
increase  the  portal  orifice:  bulbar  capacity  ratio  needed  to  assure 
adequate  bulbar  intake  during  the  pumping  cycle.  In  the  doli- 
choderines this  is  accomplished  by  a  reduction  in  bulbar  capacity 
through  progressive  envelopment  of  bulb  by  cupola,  a  process 
shown  in  its  incipient  stage  in  Forclius,  and  culminating  in 
Iridomyrmex.  In  the  formicines,  bulbar  capacity  remains  un- 
altered, there  being  instead  an  increase  in  the  portal  orifice 
through  anterior  extension  of  the  portal  tips  in  the  form  of 
sepals.  Since  the  portal  is  increased  in  length  but  not  in  width, 
its  damming  potential  is  not  sacrificed.  The  development  of 
sepals  is  seen  in  its  incipiency  in  Cladomyrma. 

Two  relatively  primitive  dolichoderine  genera,  Liometopum 
and  Leptomyrmex,  having  in  common  certain  proventricular 
specializations  unique  among  the  dolichoderines,  apparently  rep- 
resent one  or  two  isolated  and  probably  long-standing  evolution- 
ary offshoots.  Both  proventriculi  feature  an  extensive  occlusory 
tract,  a  distinct  asset  to  the  damming  action  of  the  proventricu- 
lus.  Potentially,  this  occlusory  tract  tends  to  obstruct  bulbar 
operation,  but  since  it  is  articulated  laterally  by  membranous 
plicae,  it  is  easily  opened  by  l.m.l  during  bulbar  intake. 

The  adaptive  significance  of  the  passive-dam  proventriculus  of 
the  dolichoderines  and  formicines  is  reflected  by  the  full  exploita- 
tion in  these  ants  of  the  social  functions  of  crop  storage  and 
regurgitative  feeding   (Le  Masne   '53).    All  ant  genera  known 


EISNER:   ANT  PBOVENTRICULUS  485 

to  have  "replete"  castes  are  restricted  to  one  or  the  other  of 
these  subfamilies. 

Myrmicinae  and  Dorylinae 

The  proventriculus  of  the  myrmicines  (with  the  exception  of 
the  Cephalotini;  see  Emery  1888)  and  the  dorylines  has  become 
degenerated  to  the  point  where  it  consists  essentially  of  only  a 
stomodaeal  valve;  the  bulb  is  presumably  non-functional  as  a 
pump,  since  it  is  reduced  to  a  membranous  and  more  or  less 
irregularly  folded  constriction  of  the  posterior  crop.  From  the 
structure  of  the  organ  it  is  clear  that  proventricular  damming 
is  not  a  passive  process,  but  must  be  dependent  upon  muscular 
contraction,  at  the  level  of  the  stomodaeal  valve  and/or  the 
"bulb."  Although  regurgitative  feeding  is  known  to  occur 
among  some  of  these  ants  (Crematogaster;  "Wilson  and  Eisner 
'57)  nothing  is  known  about  the  length  of  time  over  which  the 
crop  can  store  nutrient.  It  is  interesting  to  note  in  this  connec- 
tion that  some  myrmicines  have  become  independent  of  the  crop 
as  the  exclusive  communal  reservoir.  Instead,  they  have  de- 
veloped a  storage  system  outside  their  own  bodies,  hoarding 
seeds  or  other  types  of  solid  nutrient. 

It  may  be  relevant  here  to  emphasize  a  major  functional 
limitation  of  the  passive-dam  dolichoderine  and  formicine  pro- 
ventriculi.  The  complete  loss  of  portal  mobility,  resulting  from 
the  acquisition  of  a  rigid  slit-like  portal,  would  seem  to  preclude 
completely  the  transfer  of  any  but  the  most  minute  particulate 
matter  to  the  midgut.  We  have  seen,  in  fact,  that  in  the  advanced 
doliehoderines,  even  minute  particles  are  not  always  passed  to 
the  midgut,  but  actually  accumulate  over  the  cupolar  face  in 
more  or  less  discrete  layers.  We  have  also  seen  that  in  the 
asepalous  formicine  proventriculi,  such  accumulation  of  particles 
does  not  take  place,  presumably  being  prevented  by  the  sweeping 
action  of  the  precupolar  constriction  of  the  crop. 

It  would  be  interesting  to  know  whether,  in  all  ants  with  a 
rigid  slit-like  portal,  there  has  been  an  increasing  dependence 
upon  cephalic  solid-withholding  devices  such  as  the  infrabuccal 
chambers  or  the  ridges  of  the  buccal  cavity  mentioned  by 
Wheeler  ('10).  It  would  even  be  worthwhile  considering 
whether  the  refinement  of  such  buccal  particle-traps  was  a  pre- 


486  BULLETIN  :   MUSEUM  OF  COMPARATIVE  ZOOLOGY 

adaptation  necessary  for  the  evolution  of  the  passive-dam  pro- 
ventriculus.  There  is  much  need  for  detailed  observations  on  the 
feeding  behavior  of  ants  having  such  proventriculi.  Just  because 
an  ant  is  seen  feeding  on  a  dead  insect,  for  instance,  does  not 
mean  that  it  is  swallowing  solid  matter,  since  it  may  actually  take 
in  only  the  juices.  One  would  even  expect  that  small  particles 
such  as  pollen  grains,  which  are  known  to  figure  prominently 
as  a  source  of  protein  in  the  diet  of  adult  honeybees,  are  of  too 
large  diameter  to  be  transferred  through  the  passive-dam  pro- 
ventriculi. 

The  proventriculi  with  mobile  portals,  on  the  other  hand,  such 
as  those  of  the  myrmicines,  pseudomyrmecines,  aneuretines,  pon- 
erines,  and  cerapachyines  (and,  for  that  matter,  of  all  other 
aculeate  families  in  which  the  organ  has  been  studied),  are  con- 
structed in  such  a  way  that  no  hindrance  would  appear  to  be 
offered  to  the  passage  of  at  least  small  particles.  Perhaps  some 
lesser  particles  such  as  pollen  grains  actually  constitute  a  staple 
source  of  protein  in  some  of  these  ants.  From  the  work  of  Bailey 
( '52)  we  know,  for  instance,  that  in  Vespa,  Bombus,  and  Proso- 
pis,  pollen  suspensions  do  not  choke  the  proventriculus  and  are 
effectively  pumped  to  the  midgut.  In  Apis,  the  proventriculus 
has  certain  structural  peculiarities  enabling  it,  at  least  under 
some  circumstances,  to  strain  out  the  pollen  grains  from  the  fluid 
crop  contents  and  selectively  transfer  them  to  the  midgut 
(Bailey  '52,  Schreiner  '52).  This  type  of  activity,  while  prob- 
ably incidental  to  the  primary  fluid-handling  function  of  the 
proventriculus,  may  be  of  importance  when  the  bee  requires  large 
quantities  of  pollen  protein  for  the  synthesis  of  brood-food  secre- 
tion (Bailey  '54).  Whether  any  activity  similar  to  the  pollen- 
transfer  action  of  the  Apis  proventriculus  occurs  in  any  of  the 
ant  proventriculi  with  mobile  portals  remains  to  be  shown. 

The  proventricular  structure  of  the  dorylines  and  myrmicines 
(with  the  single  known  exception  of  the  cephalotines)  presents 
no  obvious  obstacle  to  the  passage  of  even  large  particles,  but  we 
do  not  yet  know  whether  these  ants  actually  swallow  solids.  It 
would  be  interesting  to  know  this,  because  it  is  not  beyond  possi- 
bility that  the  "degenerate"  condition  of  the  proventriculus  in 
these  ants  is  actually  an  adaptive  response  to  changed  feeding 
habits  involving  greater  use  of  injested  solids. 


EISNER:   ANT   PROVENTRICULUS  487 

I  am  fully  cognizant  of  the  fact  that  the  often  elaborate  functional 
schemes  advanced  here  for  the  various  proventricular  types  are  largely 
speculative,  and  that  future  work  may  uncover  fallacies  in  my  reasoning. 
However,  there  is  only  one  basic  assumption  underlying  this  study  and  for 
which  I  have  no  direct  substantiating  evidence,  namely,  that  the  circular 
muscles  and  longitudinal  muscles  contract  alternately  rather  than  simul- 
taneously. Actually,  it  seems  impossible  to  conceive  of  any  workable 
proventricular  mechanism  based  on  a  synchronous  activity  of  these  muscles. 
The  other  lines  of  reasoning  used  in  connection  with  functional  interpreta- 
tions, such  as  evaluation  of  the  relative  effectiveness  of  the  various  muscles, 
are  not  completely  speculative,  since  they  are  based  in  part  on  an  estimation 
of  the  relative  mobility  of  the  various  proventricular  components  that  these 
muscles  operate.  Mobility  of  the  cupolar  quadrants,  for  instance,  is  readily 
disclosed  by  prying  with  a  glass  needle.  Similarly,  the  elasticity  of  the 
bulb  can  be  evaluated  by  observing  its  resilience  under  varying  pressure 
directly  applied. 

It  would  be  interesting  to  test  the  functional  schemes  advanced  here  by 
direct  experimentation.  I  have  not  yet  tried  to  evaluate  the  relative  damming 
efficiency  of  the  various  proventricular  types  by  determining  1)  the  amount 
of  fluid  that  can  be  stored  in  the  crop,  and  2)  the  length  of  time  over 
which  storage  can  be  maintained.  However,  such  studies,  and  others  along 
these  general  lines,  are  currently  planned  or  already  under  way  in  this 
laboratory.  The  use  of  radioactive  tracers  appears  to  be  especially  promis- 
ing. A  preliminary  investigation  on  the  relative  importance  of  regurgitative 
feeding  in  several  representative  species  of  ants  is  in  press  (Wilson  and 
Eisner    '57,  Eisner  and  Wilson,   '57).

The  measurements  given  for  proventricnlar  length  were  taken 
between  cupolar  summit,  or  sepal  tips,  to  the  base  of  the  bulb 
at  the  point  of  insertion  of  the  stomodaeal  valve. 

All  longitudinal  sections  show  only  one  half  of  the  proventric- 
ulus,  and  are  taken  through  the  interplicary  cuticle  of  the  bulb, 
midway  between  the  plicae.

closed  circular  anal  grooves  have  been  incompletely  investigated 
and  all  such  ticks  have  been  referred  to  the  species  Ixodes  rasus 
Neumann  1899.  This  approach  to  the  diagnoses  of  these  ticks 
was  established  by  Nuttall,  Warburton,  Cooper  and  Robinson 
(1911)  and  used  indiscriminately  until  Schulze  (1943)  sub- 
divided rasus  into  three  subspecies  (see  later).  Consequently, 
at  the  present  time  the  status  of  rasus  and  other  forms  as  yet 
undescribed  presents  an  interesting  problem  to  the  systematist. 
This  uncertainty  of  structure,  coupled  with  our  ignorance  of  the 
biology  of  the  rasus  group,  opens  up  a  particularly  interesting 
and  virgin  field  for  research,  and  not  a  few  unknown  allied 
species  undoubtedly  await  discovery. 

Nuttall  (1911)  classified  I.  rasus  in  the  biological  group  within 
the  genus  Ixodes  in  which  males  and  females  coexist  together 
on  a  host  that  either  wanders  or  does  not  travel  far  and  in  the 
subgroup  where  the  sexes  are  found  in  copula  on  the  host.  Even 
so,  the  published  reports  show  that  the  host  range  of  the  adults 
of  the  I.  rasus  group  varies  from  small  insectivores  (mice,  ele- 
phant shrews)  to  leopards,  large  antelopes,  domestic  dogs  and 
man.  The  picture  for  immature  stage-host  relationships  is  more 
uncertain.

(Figures  1-13) 

Ixodes  rasus  Neumann  (1899),  pp.  137-39,  Figs.  12-14,  described  from  3 
females  and  1  male  (cf.  Remarks  below)  from  Belgian  Congo  (cf. 
Bequaert,  1931,  who  refers  type  locality  to  French  Equatorial  Africa). 
Nuttall,  Warburton,  Cooper  and  Robinson  (1911)  repeat  Neumann's 
description  of  the  male,  and  describe  another  species  of  female  (see 
under  Ixodes  pseudorasus) .  Schulze  (1943)  subdivided  rasus  into  three 
subspecies,  viz:  /.  rasus  rasus,  I  rasus  cumulatimpunctatus  and  /.  rasus 
eidmanni.    (Cf.  Remarks  below.)

Type  material.  Originally  described  by  Neumann  (1899,  pp. 
137-39)  from  three  females  and  a  copulating  male,  from  Hyrax 
species  collected  in  "the  Congo"  in  A.  Mocquerys  coll.  1899. 
The  present  labelling  of  these  specimens  reads  "740.  Ixodes 
rasus,  1  male,  2  females  (-1  female)  Hyrax  species,  A.  Mocquerys 
coll.  1899.  G.  Neumann  det."  An  anomalous  situation  occurs 
here  as  Neumann  stated  that  there  were  three  females,  whilst 
the  present  information  states  "2-1  females,"  and  accordingly 

1  propose  that  the  remaining  female  specimen  becomes  the  electo- 
type.  Electotype  female,  and  allotype  male  deposited  in  the 
Neumann  collection,  No.  740,  at  the  Ecole  Nationale  Veterinaire,

Distribution.  From  the  records  we  have  examined,  Ixodes 
rasus  is  to  be  found  in  many  parts  of  West  and  Central  Africa 
and  is  common  locally  in  East  Africa.  WEST  AFRICA.  Sene- 
gal, Ivory  Coast,  Gold  Coast;  CENTRAL  AFRICA.  Fernando 
Po,  Cameroons,  French  Equatorial  Africa  (Bequaert  1931  re- 
fers the  type  locality  to  French  Equatorial  Africa,  not  to  the 
Belgian  Congo),  Belgian  Congo;  EAST  AFRICA.  Uganda, 
Nyasaland,  Northern  Rhodesia,  Sudan.  Previous  records  of  I. 
rasus  from  Southern  Rhodesia  (Nuttall  1916)  refer  to  I.  pseudo- 
rasus and  those  of  Cooley  in  the  Rocky  Mountain  Laboratory, 
Montana  to  Ixodes  pilosus.  The  material  of  the  records  of  Bed- 
ford 1929  and  1932  are  not  available  for  re-examination. 

Hosts.  The  wide  range  of  hosts  for  the  adults  previously  given 
for  /.  rasus  has  now  become  considerably  reduced  (cf.  Hoog- 
straal,  1956).  The  immature  stage-host  relationships  must  re- 
main in  abeyance  until  such  time  as  the  larvae  and  nymphs  are 
bred  and  their  diagnostic  characters  ascertained.  The  present 
known  hosts  of  the  adults  are:  "wild  pig,"  Felis  pardus,  Phata- 
ginus  tricuspis,  Ccphalophus  leucogaster,  white  mongoose,  Nan- 
dinia  binotata,  Genetta  tigrina,  Cercoeebus  albigena,  antelope, 
Aulacodus     (=    Thryonomys)     swinderianus,     Colobus     badius

Biology.  Unstudied. 

Remarks.  The  Neumann  collection  at  the  ficole  Veterinaire, 
Toulouse,  contains  in  addition  to  the  electotype  and  the  para- 
type  two  lots  of  specimens  identified  hy  Neumann  as  7.  rasus 
and  bearing  the  following  data:  (1)  "Ousambara  (Afr:  or 
Allem:)  det.  by  G.  Neumann  1900,  1  female,"  and  (2)  "7.  rasus 
Nn.  Bismarckburg  (Togo).  Conradt  leg.  G.  Neumann  det.  1899. 
Berlin  Mus."  1  female.  The  first  specimen  is  I.  pseudorasus,  the 
second  7.  oldi  Nuttall  1913.  Schulze  (1943)  indicated  that  cir- 
cular anal  grooves  are  characteristic  of  this  species  and  in  some 
instances  they  may  be  drawn  out  or  narrowed  posteriorly.  This 
is  in  fact  true  for  the  electotype  (see  description).  To  what  ex- 
tent Schulze  (1943)  was  justified  in  dividing  rasus  into  three 
subspecies  is  problematical.  Schulze 's  7.  rasus  rasus  undoubtedly 
refers  to  Neumann's  rasus  and  he  adds  little  to  Neumann's  de- 
scription of  the  male  beyond  directing  attention  to  the  lobes  on 
the  ventral  side  of  the  basis  capituli  and  the  correction  of  the 
position  of  the  genital  orifice.  Similarly  he  gives  the  same 
characters  for  7.  rasus  eidmanni  stating  that  they  are  "more 
strongly  chitinized  (!)  and  darker,"  the  denticles  of  the  hy- 
postome  with  a  small  apical  hook  (true  also  for  7.  rasus),  prox- 
imity of  sensory  organs  in  the  integument  and  absence  of  a 
definite  ' '  peripheral  zone ' '  of  the  integument.  These  distinctions 
would  appear  to  me  to  be  of  doubtful  value  in  establishing  a 
subspecies,  particularly  as  the  numbers  examined  were  inade- 
quate. This  subspecies  has  been  collected  at  Rio  Muni  and  Span- 
ish Guinea.  I  have  no  specimens  of  7.  rasus  from  either  source 
and  the  only  specimens  from  Rio  Muni  constitute  a  distinct  new 
species  (Ixodes  muniensis)  which  is  described  later.  I  have 
failed  to  see  the  original  material  of  7.  cumulat imp unci atus  and 
have  seen  nothing  in  the  extensive  African  tick  fauna  investi- 
gated that  is  comparable  with  it.  The  occurrence  of  the  "sichel- 
haar"  in  the  capsule  of  Haller's  organ  in  7.  rasus  (see  Schulze 
1943)  is  applicable  to  a  large  number  of  Ixodes  ticks,  and  the 
break  in  the  chitin  within  the  depression  (trough),  to  which 
Schulze  alludes,  is  due  to  a  failure  to  appreciate  that  the  cuticle

Genital  orifice.  On  a  level  with  the  anterior  edges  of  coxae

Hosts  of  Ixodes  pseudorasus.  Leopard,  goat,  cattle,  bushbuck, 
Neotragus  mosckatus  akeleyi,  man,  dog,  Cricetomys  gambianus, 
Cephalophus,  Mungos  melanurus,  giant  rat,  Okapia  (which  ap- 
pears to  be  a  frequent  host  in  Belgian  Congo),  Centropus  super- 
ciliosus,  Neotragus  pygmaeus,  Potamochoerus  porcus,  Tragela- 
phus  script  us,  "tick-bird,"  Chevrotain,  forest  antelope,  bovines. 

Biology.  On  larger  mammals  the  adults  occur  on  the  ears  and 
thighs  of  hosts.  Immature  stages  probably  occur  on  small  mam- 
mals but  until  breeding  experiments  of  these  stages  are  completed 
it  is  inadvisable  to  name  possible  hosts. 


ARTHUR:  IXODES  RASUS  GROUP  513 

Related  species.  Confusion  regarding  the  Ixodes  rasus  group 
has  arisen  because  of  the  acceptance  of  the  closed  anal  groove  as 
the  sole  diagnostic  character,  which  is  based  on  the  key  prepared 
by  Nuttall,  Warburton,  Cooper  and  Robinson  (1911).  At  pres- 
ent we  recognize  the  following  five  species  having  closed  circular 
grooves:  I.  rasas  Neumann,  I.  pseudorasus,  sp.  nov.,  I.  muniensis 
sp.  nov.  7.  procaviae  sp.  nov.  and  I.  thomasae  sp.  nov.  The  affini- 
ties between  rasus  and  pseudorasus  are  to  be  found  only  in  the 
form  of  the  anal  groove  and  the  long  palps.  A  comparison  of 
the  descriptions  and  figures  reveal  that  the  differences  in  the 
form  of  the  auriculae,  the  spurs  on  coxae  I  and  IV  and  in  the 
shape  of  the  genital  apron  constitute  distinctive  characters.  Both 
species  have  a  similar  geographical  range  and  if  I.  rasus  and  I. 
pseudorasus  are  to  be  considered  as  variations  within  the  species, 
as  suggested  by  Nuttall  et  al.  (loc.  cit.)  then  all  grades  of  inter- 
mediates would  be  expected.  This  is  not  so  and  out  of  140  fe- 
males examined  43  belong  to  I.  rasus  and  97  to  I.  pseudorasus 
with  no  trace  of  intermediate  forms.  Whether  the  variants  of 
I.  pseudorasus  from  Costermansville,  all  of  which  agree  among 
themselves,  should  have  subspecific  rank  is  problematical  as  only 
nine  females  were  available  for  examination,  and  far  more  col- 
lecting for  this  tick  is  desirable. 

Remarks.  Nuttall,  Warburton,  Cooper  and  Robinson  (1911) 
base  their  description  on  females  from  Uganda  (GHFN  877a), 
Oubasi  (GHFN  503)  and  from  man  and  dog,  Kumasi,  Ashanti. 
It  would  appear  that  these  authors  did  not  see  the  type  and  con- 
cluded that  their  description  of  the  female  differed  from  that  of 
Neumann   (1899).

Scutum.  Colour  variable  in  alcohol  preserved  specimens,  e.g., 
black,  yellow,  black  with  yellow  margins — black  with  paler  color- 
ation anteriorly  :  about  as  broad  as  long,  length  0.29  mm.,  breadth 
0.29  mm.,  greatest  breadth  at  about  mid-length,  antero-lateral 
margins  curve  gradually  to  almost  negligible  scapulae,  lateral 
margins  rounded,  lateral  carinae  very  slight  elevations  close  to 
antero-lateral  margins;  cervical  grooves  shallow,  widest  about 
midway  along,  narrowing  appreciably  behind  and  not  reaching 
postero-lateral  margins.  Punctations  very  few,  equal,  indistinct, 
small  and  shallow,  confined  to  posterior  and  lateral  portions  of 
scutum ;  specimens  examined  glabrous. 

Legs.  Moderate  length  and  thickness,  coxa  I  (Figure  50)  with 
pointed,  horn-like  external  spur,  smaller  conical  internal  spur, 
few  long  hairs  on  coxae ;  small  flange-like  saliences  on  trochanters

Anal  aperture.  Fairly  near  posterior  border;  anal  grooves 
closed,  circular. 

Belated  species.  I.  mnniensis,  like  /.  rasus  and  I.  pseudorasus, 
is  not  a  host  specific  tick  and  appears  from  the  limited  data 
available  to  be  a  West  African  species.  This  new  species  is 
readily  recognizable  from  other  species  of  the  rasus  group  by  the 
characters  which  appear  in  the  key  (p.  535).  Males  are  unknown.

tremity ;  lateral  carinae  as  minor  elevations,  becoming  wider  and 
losing  height  as  lateral  margins  reached,  short,  straight;  lateral 
field  slopes  gently  from  the  ridge ;  cervical  grooves  convergent,

short,  white,  most  prominent  anteriorly  and  laterally. 

Legs.  Of  moderate  length  and  thickness.  Coxa  I  with  sharp 
pointed,  conical,  internal  and  external  spurs  (Figure  69),  coxae 
II  and  III  Avith  moderate-sized,  round-ended,  pyramidal,  ex-

LARVA.    Unknown. 

Related  species.  The  females  of  procaviae  and  thomasac  agree 
in  the  form  of  their  auriculae  and  the  spurring  of  coxae  I  and 
1 1 .  apart  from  the  closed  anal  groove.  The  postero-lateral  exten- 
sion of  the  venter  of  the  basis  capituli  together  with  the  long, 
tapering  trochanter  spurs  make  it  readily  distinguishable  from 
other  members  of  the  rasus  complex  of  species.

article  I  with  saddle-shaped  spur  from  which  a  long  white  hair 
projects  postero-laterally,  mesial  surface  of  article  2  flat,  that  of 
3  slightly  concave.  Hypostome  (Figure  77)  long  (0.57  mm.), 
narrow,  tapering  to  a  pointed  apex,  outer  file  of  denticles  larger 
than  those  nearer  the  mid-line  and  arranged  from  base  to  apex 
as  1  row  of  1/1  files,  7  rows  of  2/2  files,  6  rows  of  3/3  files,  sur- 
mounted by  a  small  corona. 

Scutum.  Colour,  brown ;  large,  rhomboidal,  longer  than  broad 
(1.32  mm.  x  0.88  mm.)  with  greatest  breadth  in  front  of  mid- 
length  ;  antero-lateral  margins  faintly  undulate  and  convergent 
to  scapulae,  postero-lateral  margins  straight,  converging  to  pos- 
terior convexity.  Lateral  carinae  distinct,  broadening  postero- 
laterally  and  reaching  the  margins  just  behind  greatest  width, 
lateral  field  beyond  carinae  sloping  strongly.  Cervical  grooves 
weak  anteriorly  but  on  diverging  become  deeper  and  wider  de- 
pressions about  mid-length,  do  not  extend  to  the  periphery. 
Punctations  medium  size,  moderate  depth  and  uniformly  dis- 
tributed.   Glabrous  in  holotype. 

Legs.  Small  to  moderate  syncoxae  on  coxae  I-III  (Figure  76), 
short  conical  internal  spur  on  coxa  I,  large  external  spur  on 
coxa  IV,  all  coxae  trenchant;  few  hairs  of  varying  sizes  on  all 
coxae.  Trochanters  I-III  bear  well  developed  broad  rounded 
saliences,  that  on  IV  reduced  to  a  smaller  spur.  Tarsi  long,  taper- 
ing with  a  distinct  hump  beyond  Haller's  organ  (Figure  78). 

Spiracular  plate.  Oval,  with  long  axis  transverse  to  corres- 
ponding axis  of  body,  macula  antero-ventral,  dimensions  0.26  x 
0.22  mm. 

Anal  groove.  Circular  and  drawn  out  to  a  small  point  pos- 
teriorly, closed  (Figure  79). 

Genital  orifice.  Between  coxae  IV,  genital  apron  large,  oval, 
unilobed. 

This  species  is  named  for  Miss  Dilys  G.  Thomas  of  the  Ad- 
ministrative Staff  of  King's  College,  London,  who  has  exhibited 
the  greatest  patience  as  well  as  a  high  degree  of  efficiency  in  deal- 
ing with  our  continual  typing  requirements  on  acarological 
matters.

SUMMARY 

1.  The  male  and  female  of  Ixodes  rasus  of  Neumann  (1899) 
are  redescribed  and  the  systematic  status  of  the  female  of 
the  species  bearing  this  name,  as  described  by  Nuttall  et  al 
(1911),  is  critically  reviewed.  After  examination  of  a  large 
number  of  ticks  we  have  arrived  at  the  conclusion  that  the 
female  of  rasus,  as  described  by  Nuttall  et  al  should  be  as- 
signed specific  rank  as  pseudorasus.  No  such  great  variation, 
as  suggested  by  them,  occurs  in  the  specimens  we  have 
studied. 

2.  The  subspecific  forms  of  I.r.cumulatimpunctatus  and  I.r.eid- 
manni  of  Schulze  (1943)  have  not  been  observed,  and  we  con- 
sider that  in  certain  respects  his  subspecific  characters  are  in- 
adequate for  diagnostic  purposes. 

3.  The  male  of  pseudorasus  is  described  and  a  variant  of  the 
female  of  this  form  noted. 

4.  Three  other  new  species  having  closed,  circular,  anal  grooves 
are  described.  These  are  I.muniensis  (female,  nymph,  larva). 
I.procaviae  (female,  male,  nymph)  and  I.thomasae  (female). 

5.  All  species  appear  to  have  a  wide  range  of  potential  hosts.
