EDITOR'S   rREFACE. 


The  Cetoniin^  and  the  DynastinjE  are  two  of  the  smaller 
Sub-families  into  which  the  large  Family  of  Scarab^id^  is 
usually  divided. 

The  Cetoniin^e  are  in  the  main  an  Old-World  Group, 
comparatively  few  species  being  found  in  the  New  World : 
this  is  especially  true  of  South  America.  They  are  well 
known  for  the  brilliancy  of  their  coloration  and  for  the 
beauty  of  their  form.  The  Rose- Chafers  of  Great  Britain 
are  familiar  examples  of  this  Sub-family. 

There  is,  however,  no  representative  of  the  Dynastin^  in 
Great  Britain,  and  hardly  a  dozen  species  in  Europe.  They 
are,  as  this  volume  shows,  distinguished  by  the  possession 
of  horns  and  projections  on  the  head  and  prothorax,  the 
use  of  which  is  still  a  matter  of  speculation  rather  than  of 
observation. 

In  this  volume  Mr.  Arrow  deals  with  perhaps  less  than  one- 
sixth  of  the  great  "  Series  "  of  Lamellicornia — Beetles 
which  are  economically  important,  many  of  them  doing 
great  damage  to  all  sorts  of  crops,  both  above  and  below 
ground.  They  further  present  many  unsolved  biological 
problems  associated  with  the  exceptional  exuberance  of  their 
colour,  pattern,  armature,  etc.  It  is  greatly  to  be  desired 
that  the  Author  should  be  able  to  continue  his  most  efficient 
work  on  other  Families  and  Sub-families  of  this  "  Series." 


Vi  EDITOR  S    PREFACE. 

In  issuing  this  volume,  I  have  again  to  express  my  grati- 
tude to  Mr.  Guy  Marshall,  who  has  helped  in  every  possible 
way  in  the  preparation  of  the  manuscript  for  the  press,  and 
I  am  happy,  with  the  approval  of  the  Secretary  of  State  for 
India  in  Council,  to  add  his  name  to  the  title-page. 

I  wish  also  to  thank  Mr.  Arrow  for  the  gi-eat  care  which 
he  has  taken  in  the  preparation  of  his  manuscript  for  the 
press,  care  which  has  materially  lightened  the  labour  of  the 
Editors,

AUTHOR'S   PREFACE. 


In  issuing  tins  first  volume  upon  the  Lamellicorn  beetles  of 
India  it  is  a  pleasure  to  acknowledge  my  great  indebtedness 
to  the  many  iustitutions  and  individuals  who  have  given 
generous  assistance  by  allowing  the  use  of  types  and  other 
specimens,  without  which  the  work  would  have  had  little 
value.  Type  specimens  have  been  lent  to  me  by  the 
Museums  of  Paris,  Berlin  (National  Entomological  Museum), 
Vienna,  Copenhagen,  Stockholm,  Ziirich,  Oxford,  and 
Calcutta,  and  for  these  my  thanks  are  due  to  M.  Pierre 
Lesne,  Herr  Sigmund  Schenkling,  Dr.  Ludwig  Ganglbauer, 
Dr.  Adam  Boving,  Prof.  Yngve  Sjostedt,  Herr  Hans 
Wagner,  Prof.  E.  B.  Poulton,  and  Dr.  Nelson  Annandale. 

I  must  also  render  grateful  thanks  to  Mr,  O.  E.  Janson 
for  the  loan  of  many  types  from  his  splendid  collection  and 
for  affording  me  the  advantage  of  his  special  knowledge  of  the 
Cetoniinae ;  to  M.  Rene  Oberthiir  for  putting  at  my  disposal 
the  resources  of  his  museum  ;  to  Herr  Sternberg,  who  has 
generously  presented  to  me  for  the  British  Museum  the  types 
of  Indian  Dynastinse  in  his  collection ;  and  to  Capt.  Moser 
for  kindly  sending  me  for  examination  types  in  his  possession. 
Mr.  H.  E.  Andre wes  has  given  invaluable  assistance  both 
from  his  own  collection  and  by  his  unflagging  efforts  to 
stimulate  field-work  in  India ;  and  Messrs.  H.  L.  Andrewes, 
H.  Maxwell  Lefroy,  E.  E.  Green,  and  Capt.  A.  H.  Weld 
Downing  have  made  important  contributions   of  specimens 


VIU  AUTHOR  S  PREFACE. 

and  observations.  I  cannot  refrain  from  acknowledging, 
in  addition,  my  indebtedness  to  Mr.  Guy  A.  K.  Marshall, 
whose  most  careful  revision  has  led  to  the  detection  of 
various  errors  and  omissions  which  would  otherwise  have 
passed  unnoticed,  and  whose  constant  helpfulness  and  careful 
attention  to  the  final  stages  of  the  work  have  contributed 
considerably  to  the  appearance  and  completeness  of  the 
volume. 

In  conclusion  it  may  perhaps  be  pointed  out  that  in  this 
and  every  other  branch  of  Entomology  the  field  open  to 
work(Ts  in  any  and  every  part  of  the  Indian  region  is  still 
enormous.  An  effort  has  been  made  to  include  in  this 
volume  all  that  is  at  present  known  upon  the  subject  of  the 
Indian  insects  with  which  it  deals  (it  is  hoped  with  approxi- 
mate success),  and  something  will  have  been  accomplished  if 
it  serves  only  to  convey  some  idea  how  slender  is  the  sum 
total  of  that  knowledge  and  how  greatly  the  value  of  future 
volumes  of  this  series  may  be  increased  by  the  co-operation 
of  those  who,  by  residence  in  India,  are  iu  a  position  to 
supply  the  raw  materials.

INTRODUCTION. 


LAMELLICORNIA. 

The  LamellicorQia  form  one  of  the  best  defined  and  most  readily 
recognisable  of  the  primary  divisions  of  Coleoptera.  No 
transitional  forms  linking  them  with  any  other  group  are  known, 
so  that,  although  their  precise  origin  and  relationships  are  obscure, 
their  limits  and  chax'acteristies  can  be  fixed  with  precision. 
They  are  found  in  every  part  of  the  world  and  about  15,000  species 
have  been  named  and  described,  of  which  about  1300  belong 
to  the  Indian  fauna.  No  systematic  collecting  has  ever  been 
undertaken  in  this  enormous  and  diversified  area,  and  the  above 
number  must  in  time  be  very  largely  increased. 

The  beetles  of  this  superfamily  are  of  a  primitively  fossorial 
type,  L  e.  their  fundamental  structure  has  been  determined  by 
burrowing  habits  which  to  a  greater  or  less  extent  still  persist  in 
the  majority.  They  are  generally  very  compact,  with  great 
muscular  power,  but  without  much  agility,  or  grace  of  form  or 
movement.  In  some  groups  this  deficiency  is  counterbalanced  by 
very  brilliant  or  striking  coloration,  while  the  muscular  development 
of  the  head  and  thorax  and  their  appendages,  and  the  remarkable 
outgrowths  which  often  occur  upon  these  parts  of  the  body, 
produce  some  of  the  most  strange  and  bizarre  forms  to  be  found 
in  the  Animal  Kingdom. 

Structure. 

The  chief  distinctive  feature  of  the  Lamellicornia,  as  that  name 
implies,  is  found  in  the  structure  of  the  antenna,  which  is  short 
and  consists  noi^mally  of  ten  joints,  of  which  the  terminal  joints, 
commonly  three,  but  often  more,  in  number,  are  flattened  and 
elongated  transversely  so  that  a  large  part  of  their  surfaces  is 
contiguous.  These  lamellate  joints  are  articulated  together  at 
one  end  and  fitting  closely  in  the  resting  position  form  au 
organ  like  a  closed  fan.  The  apposed  faces  of  the  fan-leaves 
are  furnished  with  minute  sensory  pits  and  hairs  which  are  freely 
exposed  to  the  air  by  the  slight  separation  of  the  leaves  when  the 
beetle  is  active,  and  protected  when  it  is  at  rest  by  the  closing  of 
the  organ.  This  structure  gives  a  much  larger  proportionate 
sensory  area  than  in  simpler  types  of  antennae,  and  probably  a 
higher  decree  of  sensitiveness  has  accompanied  the  withdrawal  of 
these  delicate  surfaces  from  the  risk  of  contact  with  anything

external .  In  the  family  ScABAByEiD-^  the  leaves  ox*  lamellae  are 
brought  when  at  rest  into  close  contact.  In  the  Lucanid.e 
(e.  g.  Heterochtlies,  tig.  1)  and  Passalid.e  the  adjustment  is  less 
perfect  and  the  lamellae  less  mobile,  but  in  the  last  family 
(see  Aceralus  and  Pasmlus,  fig.  1)  they  are  brought  close  together 
by  a  partial  rolling  up  of  the  antenna.  AV' hen  a  fan-like  form  of 
aiitenna  occurs  in  other  groups  of  Coleoptera,  the  structure  of  the

joints  is  essentially  different  and  there  is  no  marked  dififerentiation 
into  footstalk  and  club. 

In  a  few  highly  modified  Lamellicornia  the  three  joints  composing 
the  club  have  undergone  a  more  or  less  complete  telescoping  one 
within  the  other,  or  are  otherwise  modified  in  such  a  way  as  to  be 
no  longer  strictly  speaking  lamellate  at  all,  but  these  are  quite 
evidently  derivatives  of  the  typical  structure  and  are  very 
exce])tional.  One  of  the  most  highly  modified  of  the?e  derivatives 
is  found  in  the  genus  Lethrus,  belonging,  strange  to  say,  to  the 
subfamily  GEOinuPiN-E,  which    is    the  only  Lamellicorn    group 


LAMELLICORNIA.  6 

(excepting  one  remarkable  genus  Pleocoma)  having  eleven  joints 
to  the  antenna ;  though  this  is  the  normal  number  in  most  other 
Coleoptera. 

The  basal  joint  oE  the  antenna  is  generally  considerably  larger 
than  the  rest,  the  second  globular,  and  those  intervening  between 
that  and  the  club  small  and  one  or  two  of  them  sometimes  wanting. 
The  antennae  are  always  ])laced  far  apart,  immediately  in  front  of 
the  eyes,  and  beneath  a  ridge  or  brow  which  divides  the  eye  in 
front  and  is  absent  only  in  the  genus  Ochodceus. 

The  form  of   these  organs  indicates   that  they  are  no   longer 
tactile  as   in   so  many  other  insects.     Various   arguments   have 
been  used  to  show  that  the  sense  either  of  smell  or  of  hearing  is 
located  in  the  antenna  of  beetles,  and   it  seems  likely  that  tliis 
highly  developed  organ  of  the  Lamellicornia  is  the  seat  of  botli 
these  senses,  if  anything  really  similar  to  the  auditory  sense  of 
higher  animals  occurs  in  insects.     Of  this  faculty  we  know  little, 
but  vocal  organs  are  common  although  not  general.     There  is  little 
doubt,  however,  that  an   olfactory  sense  is  universal  and  highly 
developed.     M.  Fabre  has  found  that  Bolhoceras  is  able  to  locate 
truffles  hidden  below  the  ground,  as  pigs  or  dogs  can  do,  but  with 
still  greater  precision.     He  observed  that  the  beetles  would   fly 
straight  to  a  particular  spot  and,  alighting,  tunnel  immediately 
downwards,  and  that  beneath  that  spot  a  truffle,  the  natural  food 
of  the  species,  was  invariably   found.      The    antennae   frequently 
differ  in  the  degree  of  development  in  the  two  sexes  and,  when 
this  is  so,  they  are  always  more  highly  developed  in  the  male  than 
in  the  female.     The  highest  pitch  of  perfection  is  found  in  males 
the  females  of  which  are  rather  inert  and  degenerate,  but  there  can 
benodoubt  that  the  individualsof  a  species  areable  to  find  each  other 
by  means  of  an  almost  inconceivably  delicate  olfactory  sense  and 
that  this  sense  is  located  in  the  antennae.     It  is  a  familiar  fact 
that  the  males  of  certain  moths,  the  antennae  of  which  are  pectinate 
(comb-like),  while  the   females   are  inactive,  are  attracted   from 
considerable  distances  to  the  latter,  even  when  they  are  enclosed 
in    dark    boxes.       Certain    Lamellicorn    beetles    (e.  g.    Pachypus, 
Clitopa)  have  wingless  females,   which  live   beneath   the  ground 
and   similarly  attract   the   males,   which   fly  in   swarms    to  their 
burrows  ;  and  it  is  interesting  to  find  that  in  these  insects  also 
the  antennas  of  the  males  are  of  the  most  highly  lamellate  type, 
while  those  of  the  females,  like  those  of  the  female  moths,  are 
much  simpler.     That  the  means  of  attraction  is  a  scent  is  shown  by 
an  incident  recorded  by  M.   Perris   in   Petites   Nouvelles  Ento- 
mologiques,  1874,  p.  383.     M.  Eeveliere  happened  to  observe  in 
Corsica  numbers   of  male   Pachypus  cornutus  flying  in  a  certain 
direction,  and  tracing  them  to  their  destination  found  the  wingless 
female  about  a  yard  below  the  surface  of  the  ground.     This  when 
handled  squirted  out  a  milky  fluid  which  fell  upon  the  sleeve  of 
his  coat  and  also  upon  an  insect  specimen  previously  placed  in  a 
box.     Both  this  specimen  and  the  coat-sleeve  continued  for  several 
days  to  attract  flights  of  the  male  beetles.     There  are  other  beetles, 

b2 


IKTEODUCTIOX. 


nearly  related  to  the  Glow-worms,  of  which  the  females  are 
grub-like  and  lethargic,  with  rudimentary  antennae,  Avhile  the  males 
have  these  organs  of  an  extraordinarily  highly-developed  pattern. 
There  is  therefore  good  reason  for  the  conclusion  that  the  sense  of 
smell  is  one  of  the  principal  properties,  if  not  the  ojdy  one,  of  the 
Lamellicorn  antenna,  and  that  the  more  elaborate  forms  of  organ 
probably  indicate  the  exceptional  development  of  this  sense. 

The  head  is  in  almost  all  the  Lamellicornia  deeply  sunk  in  the 
thorax  in  the  position  of  repose,  so  that  the  eyes  are  partly 
witlulraw  n  into  the  prothoracic  cavity.  In  a  few,  however,  the 
prot borax  is  so  formed  tliat  the  head  can  be  folded  beneath  it, 
titting  against  the  projecting  front  coxa^  and  so  completely 
enclosing  the  mouth  and  antennae.  There  are  yet  others  (Acan- 
THOCEiuNiE)  in  which  the  prothorax  itself  can  be  folded  beneath 
the  abdomen  converting  the  body  into  a  ball,  within  Mhich  the 
tarsi,  as  well  as  the  bead-appendages,  are  enclosed. 

The  front  part  of  the  head  above  forms  the  clypeus,  which  is 
usually  largely  developed  and  sometimes  assumes  very  peculiar 
forms.  The  brow  ridge,  or  canthus,  is  sometimes  very  prominent 
and  may  be  produced  backwards,  more  or  less  completely 
surrounding  the  eye  and  dividing  it  into  an  upper  and  lower  half, 
or  forwards,  forming  a  lateral  continuation  of  the  clypeus,  to  which 
in  the  ComiN^:  it  is  united  at  the  edge. 

The  organs  of  the  mouth  vary  enormously  in  different  groups, 
according  to  the  nature  of  the  food  affected.  The  mandibles  of 
the  CoPRiN.E  and  most  of  the  Cetoniin.*:  are  soft  and  incapable 
of  biting,  but  they  are  often  large  and  very  strong,  and  in  the 
Stag-beetles  (Ll'CA>'id.e)  and  some  others  attain  an  extravagant 
size  in  the  male.  In  the  Passalid.I::  they  are  very  stout  and 
bear  a  movable  tooth,  a  remarkable  feature  not  found  in  any 
other  insect.  The  maxillae  are  generally  sharp  biting  organs,  but 
sometimes  bear  tufts  of  hair  for  absorbing  and  conveying  to  the 
mouth  the  juices  which  form  the  insects'  food.  The  palpi  of  the 
maxilla)  and  labium  are  simple  and  short,  the  first  consisting 
generally  of  four,  and  the  second  of  three  joints.  The  ligula  is 
well-devtdoped  and  chitinised  in  the  Lucanid.t:  and  Passalid^, 
small  and  Heshy  in  most  of  the  Scarab.iim:,  and  in  the  groups 
placed  first  in  the  present  work  reduced  to  a  mere  rudiment  upon 
the  inner  face  of  the  mentum.  The  mentum  is  enlarged  in  various 
groups  inhabiting  ants'  nests,  forming  a  shield  which  may  coincide 
with  the  clypeus  and  completely  concealing  the  mouth  {Criq>(o(h(s, 
Cosnochilus,  &c.). 

Nearly  all  the  Lamellicornia  fly  freely,  although  wingless  forms 
occur,  occasionally  in  both  sexes  but  more  frequently  in  the  females. 
These  apterous  females  are,  as  a  rule,  rarely  seen  and  many  of  them 
are  entirely  unknown. 

The  legs  assume  a  great  variety  of  forms.  The  tarsi  are  five- 
jointed,  except  in  a  very  few  exceptional  genera  in  which  only 
four,  or  even  three,  are  visible.  These  are  partially  degenerate 
insects  livinpr  in  ants'  nests  or  in  some  other  abnormal  enviroinnent. 


LA.MELLICORNIA.  O 

In  the  ball-rolling  Coprin^,  of  which  the  well-known  Sacred 
Scarabseus  is  the  type,  the  front  tarsi  have  completely  disappeared. 
The  front  tibiae  are  the  principal  implements  for  the  manipulation 
of  the  dung  of  which  the  food-ball  is  made,  and  the  tarsi  evidently 
became  an  encumbrance  and  gradually  atrophied.  In  other  related 
genera,  such  as  Chelronitls,  the  tarsus  is  absent  only  in  the  male,  and

quite  simple  and  symmetrical,  but  they  assume  a  great  variety  of

8  INTRODUCTION. 

There  are  as  a  general  rule  six  visible  ventral  segments,  but  the 
intermediate  articulations  permit  of  little  movement  and  may  be 
completely  soldered  and  even  obliterated.  The  spiracles  number 
two  on  each  side  of  the  thorax  and  seven  on  each  side  of  the 
abdomen,  the  latter  being  entirely  situated  in  the  connective 
membranes  in  the  Laparostict  divison  of  the  Scarab.tid.i:  and  in 
part  in  the  chitinous  rings  in  the  Pleurostict  division. 

An  important  characteristic  of  the  Lamellicornia  both  in  the 
mature  and  larval  states  is  found  in  the  concentration  in  the 
anterior  part  of  the  body  of  the  central  nervous  system.  In  a 
typical  insect  this  consists  of  a  brain  and  a  median  ventral 
chord  bearing  a  series  of  ganglia  corresponding  more  or  less 
exactly  with  the  segments,  one  being  in  the  head,  three  in  tlie 
thorax  and  usually  eight  in  the  abdomen.  In  the  Scakae^id-E  two 
or  (sometimes)  all  of  the  thoracic  and  all  the  abdominal  ganglia  are 
found  collected  into  a  single  mass  between  the  first  and  second 
thoracic  segments,  the  abdomen  being  supplied  only  by  the  lateral 
nerve  branches  given  off  in  pairs  from  the  posterior  part  of  this 
mass.  In  the  Lucanid  larva  the  ganglia  are  distinct  and  form  a 
chain,  but  in  the  adult  beetles,  although  not  massed  together  as  in 
the  ScAKAB.EiD.^,  they  are  reduced  in  number  and  do  not  extend  into 
the  abdominal  region.*  In  the  remaining  Lamellicorn  family, 
Passalid.e,  no  part  of  the  internal  anatomy  has  hitherto  been 
described  and  the  condition  of  the  central  nervous  system  of  larva 
and  imago  is  shown  in  the  accompanying  diagram.  In  the  larva  the 
ganglia  are  all  distinct  and  distant,  the  first  three  placed  one  in 
each  thoracic  segment,  the  fourth  also  accompanying  the  metathorax, 
while  the  first  seven  abdominal  segments  contain  one  each.  In  the 
imago  a  striking  change  takes  place.  The  cephalic  and  first 
thoracic  ganglia  alone  remain  distinct,  and  all  succeeding  ones  are 
massed  together  in  a  short  rod-like  body  the  hinder  end  of  which 
reaches  no  farther  than  the  point  of  origin  of  the  second  pair 
of  legs.  A  pair  of  strong  nerve  fibres  run  from  the  extremity  of 
this  body  into  the  abdomen  and  several  other  pairs  arising  before 
the  extremity  and  running  parallel  with  them  indicate  ganglia  no 
longer  separately  distinguishable.  Thus  the  Passalid  larva,  which 
externally  has  the  most  abnormal  organisation  among  Lamellicornia, 
is  entirely  primitive  in  its  nervous  system,  while  the  imago,  which 
also  is  of  a  highly  peculiar  and  isolated  form,  is  in  that  respect 
almost  identical  with  the  Scarab.'EID.t:. 

The  internal  anatomy  of  the  Lamellicornia,  as  represented  by 
the  common  European  Cockchafer,  MdoJontha  vulijar'm,  was  the 
subject  of  the  elaborately  illustrated  Monograph  of  Straus- 
Durckheim,  published  in  1828,  "  Considerations  genorales  sur 
I'Anatomie  Comparative  des  Animaux  articules,"  and  later 
investigations  have  been  collated  by  Professor  Kolbe  in  his 
"  Einfiihrung  in  die  Kenntniss  der  Insecten,"  1893.  The  alimen- 
tary canal  has  been   studied   in   many  representative  genera  by

Mingazzini  in  his  "  Ricberclie  sul  caiiale  digerente  dei  Lamellicorni 
litofage."  *  Generally  speaking,  that  of  the  larva  is  short  and 
nearly  straight,  with  its  anterior  part  large  and  encircled  by  two 
or  three  distinct  series  of  glandnlar  sacs  of  varying  form.     Near 

the  posterior  end  of  the  intestine  there 
is  usually  a  large  dorsal  caecum  in  which 
part  or  all  of  the  unassiinilated 
contents  of  the  stomach  are,  for  a  time, 
retained  and  which  is  often  visible 
as  a  large  dark  mass  through  the  semi- 
transparent  skin  of  the  last  dorsal 
segment  of  the  body.  In  many  of  the 
CoPBiN^  there  is  a  remarkable  dorsal 
hump  apparently  serving  only  for  the 
accommodation  of  this  csecum.  The 
contents  form  the  material  with  which 
the  cells  occupied  by  the  latter  insects 
are  repaired  when  necessary  and  of 
which  in  other  groups  the  cocoon  is 
chiefly  or  entirely  made  when  the  time 
for  pupation  arrives.  In  the  Lucanid,!, 
and  probably  in  some  Scakab.eid.e,  this 
sac  is  little  developed  and  in  Passalid.e 
it  is  absent. 

In  the  adult  beetle  the  digestive 
tube  becomes  very  much  elongated 
and  convoluted.  The  changes  which 
occur  in  Cetonia  and  Melolontha  were 
described  and  figured  by  Eamdohr  in 
1811  (Abhandlung  iiber  die  Yerdauungswerkzeuge  der  Insecten). 
In  the  adult  Passalid  the  intestine  shortly  before  its  termination  is 
completely  encased  in  longitudinal  bands  of  very  peculiar  large 
spongy  outgrowths  which  retain  their  form  even  in  completely 
dried  specimens. 

Larvce. 
Lamellicorn  larvae  are  exceedingly  similar  and  easily  recognised. 
The  body  is  long,  more  or  less  cylindrical  and  normally  bent  into 
the  form  of  the  letter  C,  the  legs  being  well-developed  and  lying  in- 
side the  curve.  Although  well-formed  the  legs  are  only  used  for 
locomotion  in  exceptional  cases,  as  in  the  Passalid^,  the  majority 
of  the  species  l.ving  always  upon  the  side  or  back  beneath  the 
ground  or  in  decaying  wood,  where  they  are  surrounded  by  suit- 
able food  and  need  only  slight  powers  of  movement.  Such 
movement  as  is  necessary  is  performed  chiefly  by  contractions 
of  the  body  rings  assisted'  by  the  erect  bristles  with  which  these 
are  provided,  and  some  larvas  when  placed  upon  a  flat  surface 
invariably  turn  upon  their  backs  in  order  to  propel  themselves 
along  in  that  ^^ay.     The  head  is  large,  very  hard  and  set  at  right

angles  to  the  axis  of  the  body,  and  the  three  thoracic  segments  are 
short,  so  that  all  the  legs  are  brought  close  together  near  the  head. 
The  integument  is  stout  but,  except  that  of  the  head,  not  chitinous, 
and  in  the  two  posterior  thoracic,  and  the  first  six-  or  seven 
abdominal   rings,   is  thrown  into  deep   folds,   generally  three  to

each  segment,  but  these  are  absent  in  the  Lucaxid.l",  Passalid.*:, 
and  a  few  of  tl»e  Scarab.eiu,!;.  The  three  or  four  last  abdominal 
segments  are  very  large  and  have  tlie  integument  stretched  to  its 
fullest  extent,  smooth,  and  often  partly  lrans[)arent.  In  many 
(."oi'RIN.t:  a  large  hump  appears  upon  the  back  as  already 
mentioned. 

Eyes  are  rarely  fouiul,  but  the  antennae  are  well-developed. 
They  are  generally  slender  and  consist  of  four  joints,  but  in  the 
Passalid-D  they  are   very  short  and  consist  of  only  two  joints. 


LAMELLICOBXIA.  11 

The  front  part  of  the  head  forms  a  small  transverse  clypeus,  to 
which  is  articulated  the  flap-like  labrum  which  lies  upon  the 
bases  of  the  mandibles.  These  are  strong  and  exposed.  The 
maxillae  are  fleshy,  but  generally  bear  strong  horny  teeth,  and  are 
of  two  types,  terminating  in  a  single  lobe  in  the  Lucanid.t-;  and 
Pleurostict  Scarab^idte  and  in  two  lobes  in  PassalidyI;  and  the 
remainintr  ScAEAii.MD.E.  The  labium  is  small  and  soft  and  carries 
a  pair  of  small  two-jointed  palpi.  Of  the  three  thoracic  segments  the 
first  alone  has  a  pair  of  spiracles,  and  the  first  eight  abdominal 
segments  have  each  a  pair.  The  back  is  studded  with  minute 
spines  which  produce  a  rough  sensatiun  to  the  touch  and  assist  in 
progression,  and  probably  also  render  the  grub  a  less  agreeable 
article  of  food.  There  is  sometimes  in  addition  a  thin  clothing  of 
stiif  hairs. 

The  leg  consists  of  four  joints,  viz.,  a  long  basal  joint,  the  coxa,, 
a  short  trochanter,  whicli  is  inmovably  attached  to  the  third,  the 
femur,  and  finally  the  tibio-tarsus,  at  the  extremity  of  which  is  a 
single  claw. 

The  larvae  of  many  typical  genera  of  Lameliicornia  were  very 
carefully  described  and  ficfured  by  Schiildte  in  Xaturhistorisk 
Tidsskrift  (3)  ix.  1S74,  and  other  descriptions,  togetlier  with  a 
useful  tabular  statement,  were  published  in  1875  by  Perris  (Ann. 
Soc.  Linn,  de  Ijyon,  vol.  xxii.). 

I'ocal  Organs. 

Lamellicorn  beetles  are  remarkable  for  the  variety  of  stridulat- 
ing  organs  to  be  found  amongst  them  and  still  more  lor  the 
occurrence  of  these  structures  in  the  larvae — a  phenomenon  which, 
so  far  as  is  known,  is  unique.  They  appear  to  be  much  more 
general  in  the  larvae  than  in  the  perfect  insects,  although  fairly 
frequent  in  the  latter,  and  when  present  in  both  stages  it  is  always 
in  entirely  different  parts  of  the  body. 

Although  aft'ecting  a  great  variety  of  positions  the  organs  are 
always  of  the  same  general  type.  A  modification  is  prochiced  of 
two  parts  of  the  body  between  which  friction  occurs  in  the 
ordinary  movements  of  the  insect  and  one  of  the  modified  surfaces 
bears  minute  and  closely-ranged  ridges  or  prominences  of  very 
hard  chitiii,  capable  of  vibrating  and  so  producing  a  shrill,  more  or 
less  musical,  note.  They  have  been  described  in  some  detail  in 
the  Transactions  of  the  Entomological  JSocielv  of  London,  1904 
(p.  709). 

In  larvae  of  CETOxiixji,  Dynastin.t:  and  Rutelinj: ,  an  oval  area 
is  found  upon  the  lower  face  of  each  mandible  which  when 
magnified  is  seen  to  consist  of  a  number  of  regular  sharp  ridges 
placed  close  togetlier  and  crossing  the  area  transversely.  Upon 
the  upper  surface  of  each  maxilla,  near  the  base,  in  a  position 
corresponding  to  tlie  ridged  plate  upon  the  mandible,  is  a  row  of 
sharp  horny  hooks,  and  these,  by  movements  of  the  ja\^s,  pluck  the 
mandibular  chords  or  ridges  and  so  produce  ;  faint  high-pitched 
note.     In  some  other  groups  of  Scabab.eid-i:  (Melolonthin.'e  and 


12  INTRODUCTION. 

C0PEIN.5)  the  mandibular  ridges  are  represented  by  irregular 
tubercles  and  the  apparatus  seems  comparatively  imperfect.  It 
has  not  yet  been  ascertained  what  sound,  if  any,  is  produced  by  thest- . 
In  the  larva?  of  the  Stag-beetles  (Lucanid.?;)  a  highly  chitinised 
area  appears  at  the  base  of  each  intermediate  leg,  and,  when 
examined,  this  is  seen  to  be  closely  studded  with  short  pointed 
tubercles.  If  a  living  larva  is  held  in  the  lingers  it  will  be  found 
to  draw  the  hind  leg  sharply  across  this  part  of  the  preceding 
one  and  at  the  part  of  the  former  where  the  contact  occurs  may  be 
seen  another  very  hard  chitinous  surface.  The  trochanter  is 
drawn  out  into  a  long  straight  file  and  its  inner  edge  is  provided 
with  a  series  of  microscopic  sharp-edged  ridges  placed  transversely. 
If  the  insect  be  held  near  the  ear  the  vibrations  set  up  by  the 
friction  of  the  studded  plate  against  these  ridges  can  be  distinctly 
heard.  In  the  genus  G'eotn/pcs  (ScARAB.EiD.i;)  sound  is  produced 
by  similar  means,  but  here  the  hind  leg  is  considerably  shortened 
and  the  joints  appear  solidified,  while  from  base  to  tip  runs  a  row 
of  sharp  horny  teeth.  Corresponding  with  these,  the  horny  area 
at  the  base  of  the  second  pair  of  legs  is  furnished  with  tine  close 
ridges,  so  that  the  functions  of  the  two  parts  are  rever.-ed.  The 
shrunken  hind  leg  has  quite  lost  its  original  function,  for  its 
direction  is  changed  and  it  is  inclined  forwards,  resting  upon  the 
preceding  limb  and  always  ready  to  make  music.  The  last  stage 
in  this  remarkable  transformation  of  an  organ  of  locomotion  into 
one  of  vocalisation  is  found  in  the  Passalid.e.  The  larvae  of  this 
family  are  quite  active,  less  unwieldy  in  form,  and  provided  with 
better-proportioned  legs  tlian  other  Lamellicorn  larva>.  Tlie  latter, 
however,  seem  to  be  only  four  in  niunl)er.  'J  he  last  pair  are  so 
much  reduced  as  to  be  scarcely  visible  without  a  lens,  w  hich  reveals 
them  in  a  form  resembling  tiny  scales.  These  leg-vestiges  are 
])rovided  with  several  hooked  claws  at  the  margin  or  lower  surface 
and  lie  close  to  the  body  upon  a  microscopically  ridged  plate  like 
that  of  Geoii-u2>cs  (fig.  7).

In  the  adult  Passalid.t  the  legs  are  all  perfectly  normal,  and 
stridulation  is  accomplished  by  the  friction  between  the  wings  and 
the  upper  surface  of  the  abdomen.  A  small  area  upon  eacli  wing 
is  studded  beneath  with  peculiar  hard  short  spines  and  against

these  works  a  similarly  specialised  vibratory  elevated  area  or  boss 
upon  each  side  of  the  ante-penultimate  dorsal  tergite.  In  the 
isolated  and  peculiar  genus  Ochodcvus  a  similar  but  still  more 
highly  specialised  structure  is  found  at  the  same  part  of  the  back, 
in  the  form  of  a  small,  curiously  sculptured  club-like  projection. 

The  LuCAKiD.i:  seem  in  the  adult  stage  to  be  practically  voiceless, 
a  single  South  American  species,  Cldasognatlius  grauti^  being  the 
only  one  known  to  stridulate — in  this  case  by  drawing  the  hind 
femur  across  a  "  milled  "  band  at  the  outer  edge  of  the  elytron. 

The  only  groups  of  JScaeabtEid.e  characterised  by  a  single 
recurring  type  of  vocal  organ  are  the  Geotrupin.e  and  Orphnin^, 
in  a  large  pi'oportion  of  which  the  hind  coxa  bears  a  finely  ridged 
area  scraped  by  the  sharp  edge  of  the  coxal  cavitj^  and  the 
Dtnastin.^,  of  which  many  genera  have  fine  transverse  ridges 
upon  the  propygidium,  which  by  movements  of  the  abdomen  is 
drawn  across  the  hinder  edges  of  the  elytra.  The  latter  type  is 
highly  developed  in  the  Indian  Dliiclicus  (fig.  8),  the  propygidium 


Fig.  8. — Diagrammatic  representatiou  of  the  terniinal  segments  of  Bipelicuf:

of  which  is  considerably  produced  at  the  expense  of  the  last 
segment.  In  Hcteronychus  and  related  genera  a  pair  of  stridula- 
tory files  occurs  in  the  same  situation.  Other  situations  in  which 
the' vibratory  ridges  occur  in  diiferent  Indian  genera  of  Scaeab^id.e 
are — at  the  inner  edge  of  the  elytron  in  the  two  large  genera  Tro.c 
and  Copris,  the  vibrations  being  set  up  in  both  cases  by  the 
movement  of  the  abdomen  ;  within  the  hind  coxal  cavity  iu  the 
great  beetles  forming  the  genus  Heliocopris,  the  apparatus  being 
scraped  by  sharp  projections  upon  the  coxa ;  and  upon  the  inside 
of  the  prosternum  in  Serica,  in  which  the  edge  of  the  mesoaternum 
forms  the  other  part  of  the  instrument.  In  the  curious  little 
beetles  of  the  genus  Ocliodceas  mentioned  above  another  quite 
diflferent  apparatus  is  found.  Beneath  the  elytra  on  each  side  of 
the  antepenultimate  segment  of  the  abdomen  is  a  minute  process, 
assuming  various  peculiar  shapes  in  diiferent  species,  but  always 
studded  with  teeth  or  tubercles  capable  of  playing  upon  a  micro- 
scopically sculptured  area  upon  the  corresponding  lower  surface  of 
the  elytron.  In  some  large  groups  of  Lamellicoknia  peculiar 
types  of  stridulating  organs  have  been  found  in  representatives 
inhabiting  otlier  parts  of  the  world,  but  none  as  yet  iu  any  Indian 
representatives.  Thus  in  several  South  American  genera  of 
EuteltN/E  a  striated  plate  occurs  at  the  end  of  the  hind  femur  (and 
the  middle  femur  also  in  a  few  species),  the  ridges  being  made  to 


14  INTEODUCTIOX. 

vibrate  by  rubbing  the  legs  against  sharp  obUque  ridges  at  the  sides 
of  the  abdomen  or  tbe  edges  of  the  elytra,  and  in  Iscliiopsopha,  a 
Papuan  and  Australian  genus  of  Cbtomix.e,  at  the  sides  of  two  or 
three  of  the  abdominal  segments,  which  are  scraped  by  riilges  on 
the  inner  face  of  the  hind  femora. 

The  sound  produced  by  these  organs  is  generally  a  very  high- 
pitcbed  and  by  no  means  loud  musical  note,  sometimes  only 
audible  by  the  human  ear  wlieu  the  insect  is  held  within  a  few 
inches.  It  is  in  no  way  comparable  with  that  emitted  by  the  vocal 
■organs  of  Crickets,  Grasshoppers,  or  Cicadas;  there  is  no  contrivance 
in  the  Coleoptera  for  increasing  the  volume  of  sound,  nor  is  the 
faculty,  except  in  a  very  few  highly  exceptional  instances,  peculiar 
to  the  males  as  in  the  former  insects.  The  use  of  the  faculty  is 
verv  doubtful.  Darwin  expressed  himself  unable  to  conceive  of  any 
purpose  it  could  serve  except  communication  between  individuals  of 
the  two  sexes  or  emulation  between  those  of  the  same  sex.  The 
facts  mentioned  above,  and  indeed  most  of  the  results  of  recent 
investigation,  seem  to  me  opposed  to  this  explanation,  especially  as 
no  organ  even  probably  auditory  in  function  lias  been  found  in  any 
beetle  and  no  completely  satisfactory  evidence  has  been  obtained 
that  an  auditory  sense  exists.  Unless  this  can  be  shown  we  must 
look  for  the  significance  of  the  stridulaling  organs  in  their  effect 
upon  some  other  animals  than  those  possessing  them.  Mr.  Guy 
Marshall  has  suggested  (Trans.  Ent.  Soc.  Lond.  1902,  p.  403)  that  in 
many  instances,  and  especially  when  the  habits  are  nocturnal,  the 
sounds  may  serve  to  protect  the  insects  from  enemies  by  indicating 
nauseous  qualities  or  in  some  cases  by  suggesting  the  buzzing  of 
sting-bearing  species.  Although  it  is  very  probable  that  the 
origans  may  have  in  many  cases  acquired  such  uses,  a  survey  of  all 
those  groups  in  which  stridulation  is  known  respectively  to  occur 
and  not  to  occur  seems  to  me  to  preclude  the  idea  that  the  faculty 
is  to  any  large  extent  a  concomitant  of  unpalatability.  For 
reasons  which  I  propose  to  discuss  elsewhere  it  seems  to  uie 
possible  to  account  for  all  the  known  phenomena  and  to  explain 
the  evolution  of  the  structures  concerned  upon  the  hypothesis  that 
stridulation  is  in  itself  an  unpleasant  property  and  a  forui  of 
protection  against  insectivorous  animals.  If  this  view  is  correct 
the  sound  is  not  the  essential  feature  but  only  a  bye-product  of 
the  vibration,  which  in  hard-shelled  insects  nuist  be  com- 
municated to  a  large  part  of  the  surface,  and  I  think  may  not 
unreasonably  be  supposed  to  produce  disagreeable  sensations  in  the 
mouth  of  a  captor,  as  is  recognised  to  be  the  effect  of  a  panoply  of 
spines  or  bristles.  This  theory  obviously  involves  the  rejection  of 
t  he  term  •  vocal '  organs  for  the  structures  here  described,  at  least  as 
a  general  designation. 

Several  Lamellicorn  beetles  in  which  no  striilulating  surfaces 
seem  to  exist  have  been  described  as  producing  hissing  or  piping 
sounds.  It  has  been  suggested  that  this  may  be  coiniected  with 
the  spiracles,  as  in  various  JDiptera,  but  no  precise  observations  are 
yet  forthcoming. 


LAMELLICORNIA. 


Sexual  Dhnorjjhism. 


15 


A  special  characteristic  of  the  Lamellicornia  is  the  tendency  of 
the  sexes  to  differ  markedly  iu  their  external  features.  There  is 
no  particular  in  which  the  differences  may  not  manifest  themselves. 
Colour,  vestiture,  size  and  structure  are  alike  liahle  to  them,  and 
in  many  cases  there  is  so  little  resemblance  between  male  and 
female  that  they  have  been  regarded  as  distinct  species  and  even 
ffenera.     In  the  Passahdj;;  alone  are  marked  external  differences 

O 

entirely  absent. 

In  tiie  ScARAByEiDyE  there  is  a  tendency  to  tlie  occurrence  of 
horns  upon  the  head  and  thorax  in  the  male.  Such  appendages 
may  be  possessed  by  both  sexes,  but  they  are  very  rarely  equally 
developed  in  both  and  are  generally  represented  by  mere  rudiments 
in  the  female.  Occasionally  thearmature  is  of  nearly  equal  develop- 
ment but  of  different  form  in  the  two  sexes,  and  only  in  two  known 
species  {Onitis)is  it  more  developed  in  the  female  than  in  the  male. 
Such  structures  ai'e  found  in  their  fullest  development  in  the 
males  of  the  large  beetles  belonging  to  the  Subfamily  Dynastin.!;. 
These  flourish  chiefly  in  Tropical  America,  but  the  well-known 
Xylotrupes  gideon,  which  is  abundant  throughout  Tropical  Asia, 
and  Chalcosoma  atlas,  shown  at  Plate  II,  fig.  12,  are  excellent 
examples.  Although  generally  of  smaller  size,  some  of  the  species 
of  the  Subfamily  Coprin^.t:  exhibit  still  more  extraordinary  forms 
of  armature  upon  the  head  and  thorax  of  the  male. 

To  the  same  category  belong  the  enormously  enlarged  mandibles 
sometimes  characterising  the  males.  These  are  ahnost  universal 
in  the  Soag-beetles  (LrCANiM:)  and  occur  more  rarely  iu  various 
groups  of  ScAEAB^BiD^,  Dicaulocepluilus  falcifer  being  a  striking 
Indian  example.  Tlie  two  forms  of  armature  are  never  found 
together.  Although  the  mandibles  are  normally  highly-developed 
in  the  Dynastin^,  in  the  males  of  which  horns  are  so  common  a 
feature,  no  sexual  development  there  takes  place  in  the  mandibles 
except  in  a  few  hornless  forms  (e.  g.  Aiicognatha),  and  such 
hypertrophy  of  the  mandibles,  wherever  it  is  found,  in  the 
LucAiNiD^,  in  Geotrupin.e,  HYBOSORiNiE,  Melolonthin^,  or 
KuTELiKvi;,  is  never  accompanied  by  cephalic  or  thoracic  outgrowths. 

These  structures  are  in  some  cases  used  as  weapons  of  offence 
in  contests  between  males  of  the  same  species,  and  in  some  others 
of  the  less  extravagant  forms  serve  as  tools  in  the  task  of  nest- 
construction,  as  M.  Pabre  has  described  in  Coprh  hispanus  and 
Geotnipes  Ujpliams.  But,  although  they  are  commonly  assumed  to 
be  all  explainable  in  a  similar  manner,  there  are  many  reasons  for 
believing  that  these  uses  are  secondary  and  afford  no  explanation 
of  the  origin  of  the  armament.  The  horns  are  never  sharp  or 
capable  of  inflicting  injury  upon  such  well-protected  bodies  as  all 
these  beetles  possess,  and  they  are  sometimes  extremely  slender 
and  brittle  and  directed  backwards  so  that  no  practical  use  of  any 
kind  can  be  imagined  for  them.     Thus  the  male  of  the  African 


16  INTRODUCTION. 

Onthopliagns  rangifer  bears  u[)on  the  head  a  pair  oE  long  chitinous 
filaments  streaming  backwards  almost  horizontally  and  knobbed  at 
the  ends,  while  in  the  South  American  Golofa  porteri  the  head 
and  thorax  each  bear  a  very  slender  and  brittle  rod  standing 
up  vertically.  It  has  been  pointed  out  that  such  extravagant 
outgrowths  are  often  found  in  fossil  animals  of  races  which  have 
no  present  day  representatives,  a  possible  reason  for  their  total 
disappearance  being  that  the  hypertrophy  has  reached  a  stage  of 
such  serious  inconvenience  as  to  result  in  the  ultimate  extinction 
of  the  race  in  competition  with  others  not  so  handicapped.  Perhaps 
they  are  best  regarded  as  analogous  to  some  characteristics 
of  the  aristocracy  in  certain  races  of  mankind,  such  as  the  con- 
tracted feet  and  long  nails  of  the  Chinese,  that  is,  as  practical 
inconveniences  endured  with  satisfaction  as  the  proofs  of  an  idle 
existence.  In  the  female  beetles,  which  have  always  the  duty  of 
j)roviding  for  the  succeeding  generation,  frequently  involving  very 
laborious  and  complicated  operations,  and  in  such  males  as  co- 
operate, as  many  do,  in  these  labours,  the  operation  of  Natural 
Selection  ensures  the  development  of  every  part  of  the  body  upon 
strictly  utilitarian  lines  and  the  perpetuation  of  any  impeding  out- 
growths is  impossible ;  but  when  tliese  functions  ars  confined  to 
one  sex  this  factor  operates  upon  that  alone,  and  the  forces  which 
produce  variation,  whatever  they  may  be,  taking  the  path  of  least 
resistance,  seem  to  concentrate  upon  the  features  thus  left  free 
to  them. 

A  frequent  sexual  difference  in  the  form  of  the  front  tibiae  will 
illustrate  this  idea.  In  the  females  these  are  nearly  always  broad 
and  strong  and  provided  with  sharp  teeth  at  the  outer  edge,  an 
effective  digging  implement  resulting.  In  Passalid^,  where 
there  is  an  equal  division  of  labour  between  the  sexes,  and  in 
many  other  Laraellicornia,  no  difference  is  found  in  this  respect, 
but  in  a  very  large  number  these  limbs  are  more  slender  in  the 
males,  and  the  teeth  are  either  absent  or  so  spaced  as  to  be  evidently 
less  serviceable.  Every  stage  of  disparity  can  be  found  in  different 
species  from  one  scarcely  perceptible  until  a  grotesque  degree  of 
elongation  is  reached  in  the  male.  The  process  has  attained  its 
limit  in  the  strange  genus  Euchlrus,  of  which  there  are  two 
Indian  species. 

An  interesting  phenomenon  in  connection  w  ith  these  character- 
istics of  the  male  sex  is  the  relation  between  the  degree  of  their 
development  and  the  size  of  the  insect,  both  individualh'  and 
specifically.  The  maximum  development  is  only  found  in  the 
largest  specimens  of  their  kind  and  a  regular  diminution  accom- 
panies diminished  size  of  the  individuals,  until  in  very  dwarfed 
specimens  these  features  may  be  absent  altogether.  A  similar, 
but  less  exact,  correspondence  can  be  traced  in  the  relative  sizes 
of  the  species  of  a  group.  The  smaller  forms  are  almost  always 
without  well-marked  secondary  sexual  features,  which  become 
most  accentuated  in  the  giant  forms.  This  is  well  illustrated  in 
the  Cetoxiix.'e  and  Dyxastix.?:. 


LA.MELLICORNIA.  17 

Differences  of  coloux'  or  of  the  sculpturing  of  the  upper  surface 
distinguish  the  sexes  in  various  groups,  and  these  probably  result 
in  most  cases  in  making  the  females  less  conspicuous  than  the 
males,  by  a  closer  assimilation  to  their  usual  environment,  or 
perhaps  afford  them  special  protection  at  the  time  of  egg-laying, 
when  they  and  their  progeny  are  exposed  to  the  greatest  danger. 
The  colour  of  the  male  is  frequently  brighter,  as  in  many  species 
of  Macronota  and  Anoniala,  and  in  the  large  Chalcosoma  atlas  already 
mentioned,  the  male  of  which  is  metallic  green  and  very  smooth 
and  brilliant,  while  the  female  is  dull  and  slightly  hairy.  In 
many  of  the  Valgini  and  Hopliini  the  males  are  decorated  with 
bright-coloured  scales,  which  do  not  appear  or  are  much  reduced 
in  the  other  sex. 

There  are  many  other  differences  which  have,  or  may  be  assumed 
to  have,  a  more  direct  relation  to  the  functions  of  the  respective 
sexes  than  those  which  have  been  mentioned.  The  caudal  style 
of  the  female  Charitovalgus  is  evidently  of  use  in  oviposition, 
although  the  difference  of  habit  which  must  exist  between  it  and 
other  closely  allied  genera  has  not  yet  been  ascertained.  The 
frequent  difference  between  the  sexes  in  the  antennae  has  already 
been  referred  to.  In  Melolonthinj^  and  Rutelin.e  a  larger  club 
is  almost  universal  in  the  male,  the  component  joints  being  longer 
and  in  some  of  the  former  more  numerous,  the  footstalk  in  the 
latter  case  being  of  course  proportionately  reduced.  Similar 
differences  are  found  in  other  groups,  but  less  frequently. 

I  have  already  mentioned  the  enlargement  of  the  claws  of  many 
male  Rutelinve  and  others.  This  usually  occurs  only  in  the  inner 
claw  of  the  fore-foot,  the  claw-joint  being  generally  correspond- 
ingly enlarged  and  the  whole  tarsus  thickened  and  shortened.  In 
certain  Dtnastin^  the  enlarged  claw  is  cleft  or  toothed,  but  in 
the  RuTELiN.E  the  reverse  condition  is  not  uncommon,  this  claw 
being  cleft  in  the  female  but  entire  in  the  male.  Occasionally,  as 
in  some  species  of  Parastasia,  the  disparity  occurs  in  the  claws  of 
the  middle  foot.  In  some  Melolonthin^  and  EuxELiNiE  the 
front  tarsal  joints  of  the  male  bear  broad  hairy  pads  beneath. 

The  abdomen  of  the  male  is  often  arched  or  hollowed  beneath 
or  otherwise  different  from  that  of  the  female,  and  in  certain 
instances  where  a  stridulating  apparatus  is  borne  upon  the  dorsal 
part  it  is  found  to  present  differences  in  the  two  sexes,  perhaps  as 
a  consequence  of  the  different  form  of  the  abdomen  or  its  greater 
muscularity  in  the  male. 

A  multitude  of  other  differences,  affecting  almost  every  part  of 
the  body,  might  be  enumerated,  but  enough  have  been  mentioned 
to  show  that  in  the  Lamellicornia  these  sexual  disparities  are  of 
more  than  usual  importance  and  interest. 

Food  and  Hahits. 

Most  Lamellicorn  beetles  feed  during  the  larval  stage  upon 
dead  vegetable  or  animal  matter,  and  in  the  adult  period  upon  the 
same  substances  or  the  juices  of  plants.  The  eggs,  so  far  as  they 
have  been  observed,  are  spherical  or  shortly  elliptical  in  shape, 

c 


18  INTRODUCTION. 

with  a  smooth,  yellowish  and  rather  leathery  exterior.  In 
Melolonthin^  and  Dynastin.e  they  have  been  observed  to 
increase  considerably  in  size  before  hatching.  They  are  sometimes 
coated  with  a  glutinous  matter  so  that  they  gather  earthy  particles 
apparently  serving  for  concealment.  The  larvse  generally  Uve 
underground,  in  rotten  tree-trunks  or  heaps  of  debris,  some  doing 
considerable  injury  by  destroying  the  roots  of  grass  or  cultivated 
crops,  while  certain  kinds  greatly  offend  in  the  perfect  state  by  their 
devastations  among  flowers  or  foliage.  These  agricultural  pests 
belong  for  the  most  part  to  the  MELOLONTniN.E,  some  destruc- 
tive genera  of  which,  e.  g.  Laclmosterna,  Serica  and  Ajior/onia,  are 
found  in  great  numbers  throughout  the  East.  Orifctes  rhinoceros 
does  great  damage  to  Cocoauut  palms  by  tunnelling  through  the 
growing  top,  but  is  also  found  in  very  great  numbers  in  tan-yards, 
manure-heaps,  etc.  The  majority  of  species  of  the  great  groups 
CoPRiN^  and  APHODiiN.i:,  many  of  which  are  very  familiar,  feed 
upon  the  excrement  of  vertebrate  animals,  but  a  few  are  carrion- 
feeders.  Various  species  of  Onthophagus  devote  themselves  to 
removing  tlie  remains  of  other  insects,  etc.  Mr.  H.  M.  Lefroy 
records  tliat  0.  gravis  speedily  discovers  and  removes  the  dead 
locusts  which  at  certain  times  cumber  the  ground  in  great  numbers 
in  the  Plains.  As  all  these  transport  the  food-material  below 
ground  for  the  benefit  of  their  progeny,  they  must  be  regarded  as 
beneficial  from  the  human  standpoint. 

Although  frequently  found  in  very  large  numbers  Laraellicorn 
beetles  are  by  no  means  prolific,  many  species  laying  only  half  a 
dozen  ^gg^^,  or  even  less.  Two  or  three  years  may  be  passed  in 
development,  and  the  life  of  the  adult  may  extend  to  more  than 
one  season,  so  that  the  duration  of  life  is  comparatively  long. 

The  female  beetle  generally  tunnels  below  the  surface  of  tho 
ground  to  deposit  her  eggs,  and  elaborate  provision  is  sometimes 
made  for  the  offspring.  Both  parents  may  share  in  these  labours 
and  even  in  tending  the  young.  Probably  monogamy  is  very 
exceptional  amongst  insects,  but  in  widely  separated  groups  of 
Lamellicorns  we  hnd  the  male  and  female  associated  for  a  con- 
siderable time  and  accomplishing,  by  a  regular  division  of  labour, 
tasks  of  surprising  magnitude  and  complexity.  Most  of  our  know- 
ledge on  this  very  interesting  subject  is  due  to  M.  Fabre,  who 
has  published  (Souvenirs  Entomologiques)  a  remarkable  series 
of  observations  upon  the  habits  of  insects  inhabiting  the  South  of 
France,  where  are  found  representatives  of  many  of  the  genera 
of  the  Indian  fauna. 

From  exceedingly  early  times  the  peculiar  ball-rolling  habits  of 
the  Sacred  Scaralnvus  and  its  allies  in  Southern  Europe,  Asia,  and 
Africa  have  attracted  attention.  It  has  been  supposed  that  the 
ball  of  dung  contained  at  its  centre  the  eggs  of  the  beetle  and 
that  the  rolling  ])rocess  in  some  way  conduced  to  the  well-being 
of  the  progeny ;  but  M.  Fabre  has  shown  that  the  real  object  is 
the  transporting  to  a  suitable  retreat  of  the  food  of  the  beetle 
itself,  and  that  the  ball  which  actually  contains  the  egg  is  con- 
structed underjrrouud  in  a  burrow  to  which  the  materials  have 


LAMELLICOENIA.  19 

been  first  carried.  In  this  case  the  female  seems  to  perform  the 
whole  of  the  parental  duties,  but  in  Geotrupes,  another  genus 
common  to  Europe  (including  Britain)  and  India,  the  two  parents 
share  equally  the  labour  of  constructing  and  provisioning  the 
subterranean  nest,  each  species  excavating  a  burrow  of  different 
design  and  sometimes  of  great  extent.  In  Copris,  species  of 
which  are  found  in  nearly  every  part  of  the  world,  including 
Britain  and  India,  a  large  subterranean  chamber  is  dug  out  by  the 
two  beetles  and  provisioned.  The  eggs,  from  2  to  7  in  number, 
in  the  European  species  which  have  been  studied,  are  enclosed 
each  in  a  separate  pear-shaped  cell  of  complex  structure,  and  the- 
young,  although  invisible,  are  guarded  throughout  their  develop- 
ment by  the  mother,  who  repairs  cracks  in  the  cells,  removes 
mildew  and  probably  keeps  ofi'  enemies.  Erom  the  small  size  of  the 
families  in  these  insects  and  the  usual  abundance  of  the  species,  it 
must  be  inferred  that  the  percentage  of  larval  mortality  is  very 
low.  The  cells  made  by  some  of  the  Indian  species  of  Heliocopris 
and  Catharsius  are  very  large  and  cased  with  a  very  thick  outer 
layer  of  clay,  but  there  is  always  a  point  at  which  the  outer 
crust  thins  out,  allowing  sutficient  air  to  penetrate  to  the  interior 
for  the  purpose  of  the  inmate. 

Colonel  8ykes  described  in  1835  *  the  discovery  of  five  of  these 
balls,  which  wei'e  at  first  taken  to  be  ancient  stone  cannon-balls 
but  proved  on  examination  to  contain  beetle  pupae.  Two  of  them 
were  retained  and  the  mature  beetles  emerged  from  them  1 3  and 
16  months  later  respectively.  These  balls  were  two  inches  in 
diameter  and  belonged  to  Heliocopris  miclas,  but  this  is  not  a  very 
large  species  and  the  balls  of  Heliocopris  dominus  may  be  twice 
as  bulky.  The  beetles  are  no  doubt  able  to  remain  imprisoned 
for  considerable  periods  awaiting  the  rains  which  soften  the  hard 
crust  of  their  cells  and  allow  them  to  escape.  Mr.  Lefroy  records 
that  one  of  the  balls  has  been  found  eight  feet  below  the  surface 
of  the  ground. 

In  a  European  Greotrupid,  Lethrus  apterus,  the  male  has  been 
often  observed  guarding  the  burrow  within  which  the  female  is  at 
work,  and  fiercely  attacking  other  beetles  of  its  species  which  may 
attempt  to  appropriate  the  fruit  of  its  labours.  The  burrow  of 
this  species  gives  access  to  a  series  of  oval  chambers,  in  each  of 
which  an  egg  is  laid  and  a  store  of  food  provided,  consisting  of 
tender  shoots  of  the  vine  bitten  off  and  carried  home. 

The  highest  degree  of  social  organisation  of  which  we  are  yet 
aware  in  these  insects  is  reached  in  the  PassaliDjE,  the  habits  of 
which  have  in  recent  years  been  investigated  by  Dr.  Ohaus. 
Although  the  species  studied  are  South  American,  those  inhabiting 
India  and  most  other  warm  regions  are  so  very  closely  related 
that  the  life-histories  of  all  are  probably  very  similar.  They  feed 
upon  rotten  wood,  and  are  found  within  or  beneath  old  tree- 
trunks.  Within  each  burrow  Dr.  Ohaus  found  larvae  of  different 
ages  together  with  the  two  parents.    This,  together  with  the  results

of  such  dissections  as  I  have  made,  seems  to  point  to  thehkeUhood 
of  these  insects  being  viviparous,  which,  if  confirmed,  will  be  yet 
another  most  abnormal  characteristic  of  this  peculiar  family.  The 
larvae  are  much  more  active  than  those  of  other  Lamellicornia,  but 
seem  to  be  incapable  of  feeding  themselves  and  quickly  die  if 
separated  from  their  parents.  The  wood  is  pulverised  for  them  by 
the  jaws  of  the  latter  and,  Dr.  Ohaus  believes,  mixed  with  a 
digestive  secretion  before  it  is  supplied  to  them.  Both  larvte  and 
adults  possess  well-developed  vocal  organs,  as  already  described, 
and  Dr.  Ohaus  records  *  that  upon  one  occasion,  having  broken  up 
a  stump  and  so  dislodged  a  family  of  Passalid-E,  he  put  them  all 
upon  the  ground  and  continued  his  search  for  other  insects. 
When  about  to  leave  the  spot  his  attention  was  attracted  by  a 
fqueaking  noise  and,  being  guided  by  the  sound  to  a  log  a  short 
distance  away,  he  found  beneath  it  the  two  parent  beetles  and 
several  of  their  young  ones,  all  stridulating  vigorously,  while,  as 
if  directed  by  their  cries,  the  remaining  larvae,  also  squeaking, 
were  hastening  towards  them  as  fast  as  intervening  obstacles 
would  allow. 

The  life-history  of  most  of  the  forms  which  feed  in  partly  de- 
composed wood,  like  the  Lucanid.e  and  many  liuTELix.E,  or  in 
vegetable  debris  or  among  the  roots  of  plants,  like  most  Cetoxiin'^, 
Dyxastinm;,  and  Meloloxtiiix.!:,  is  much  simpler  and,  although 
the  larval  development  may  occupy  two  or  three  years,  the  life  of 
the  adult  is  frequently  very  short.  Thus  many  Melolonthin"^ 
appear  at  a  fixed  period  of  the  year,  are  found  in  enormous 
numbers  for  a  few  days,  and  then  disappear  completely.  The 
females  merely  deposit  their  eggs  in  loose  soil  a  little  below  the 
surface  and  the  larva)  feed  at  large  until  fully  grown.  A  cocoon 
is  then  formed  on  the  spot,  the  outermost  layer  generally  con- 
sisting of  fragments  of  earth,  wood,  root-fibres,  or  whatever 
material  forms  the  food  of  the  species,  while  the  inner  substance 
and  agglutinative  material  is  furnished,  not  by  glands  opening 
into  the  mouth,  but  by  the  intestine.  The  interior  is  oval  in  shape, 
and  its  walls  generally  quite  smooth  and  polished. 

Lamellicorn  larvae  appear  to  form  the  only  food  of  the  young  of 
the  very  large  Solitary  AVasps  of  the  genus  iScoHa.  The  female 
wasp  seeks  her  victim  underground  and  paralyses  it  by  means  of 
her  sting,  an  operation  which  is  facilitated  by  the  concentration 
of  the  ventral  nerve  ganglia  in  the  thorax  as  already  described.  A 
single  egg  is  then  laid  upon  the  immobile  body  and  the  wasp  larva, 
upon  its  emergence  a  few  days  later,  finds  a  ready  and  sufficidnt 
supply  of  food,  fresh  and  living  but  incapable  of  resistance.  The 
prey  is  speedily  reduced  to  a  hollow  skin,  the  vital  organs  being 
avoided  until  the  last,  and  the  parasite  then  forms  its  cocoon 
upon  the  scene  of  the  tragedy.t 

A  peculiar  manner  of  life  found  in  several  different  groups  is 
that  of  the  "  myrmecophilous  "  and  "  termitophilous  "  species,  that 
is,  those  which  have  attached  themselves  to  Ants  and  Termites

LAMELLICOUNIA.  21 

respectivel)^  living  and  feeding  in  the  nests  of  those  insects.  Such 
a  habit  is  generally  accompanied  by  very  marked  peculiarities  of 
structure,  often  so  great  as  to  completely  obscure  the  real  relation- 
ships of  the  species.  The  Ceemastochilini,  of  which  a  number 
are  described  in  the  present  volume,  are  good  examples  of  these 
interesting  insects.  It  seems  probable  that  these  feed  upon  the 
substance  of  the  nest  in  defiance  of  its  proper  inhabitants.  They 
generally  pi*esent  a  curiously  compact  and  invulnerable  exterior, 
^vhich  evidently  serves  to  secure  them  against  attack.  Whether 
their  larvce  possess  any  corresponding  adaptation  is  unknown. 
Another  group  appear  to  act  as  scavengers  of  the  nests  in  which 
they  live,  or  are  otherwise  serviceable  to  the  proprietors  and  are 
not  molested  by  them.  The  curious  OntJiopJiagns  myrmecopMlus, 
which  inhabits  the  nests  of  Pheidologiton  in  tree-trunks,  may  be 
inferred,  from  the  habits  of  the  genus  to  which  it  belongs,  to  have 
a  scavenging  function  there. 

Most  remarkable  of  all  are  those  forms  which  have  a  special 
apparatus  for  the  secretion  of  a  fluid,  for  the  sake  of  which  they 
are  prized  and  tended  by  their  hosts.  Two  Indian  genera  at 
least,  Coryilioderus  and  Ciicetopistlies,  belonging  to  the  Subfamily 
CoPRiiSr.^,  are  of  this  class.  In  these  certain  deep  cavities  exist  in 
the  prothorax  or  elyti'a  into  which  secretory  glands  open  and  from 
which  spring  tufts  of  bright  yellow  hairs.  The  fluid  probably 
flows  over  these  hairs  and  is  licked  off  by  the  Termites  with  which 
tlie  various  species  of  these  two  genera  live  ;  or  possibly  the  hairs 
are  connected  with  a  nervous  apparatus  and  their  stimulation  by 
the  Tei-mites  promotes  the  secretion.  The  organs  of  the  mouth 
are  degenerate  in  the  beetles,  an  indication  that  they  ai'e  fed  by 
their  hosts ;  and  from  exactly  similar  phenomena  in  quite  other 
groups  of  beetles,  it  can  safely  be  assumed  that  the  secretion  is 
regarded  as  a  luxury  by  the  hosts  and  for  its  sake  the  beetles  and 
their  young  are  cherished  and  all  their  wants  supplied. 

Classification. 

It  will  be  found  that  in  the  course  of  this  work  methods  of 
classification  more  or  less  at  variance  with  those  at  present  adopted 
have  been  introduced,  and  names  of  genera  and  species  now  in 
frequent  use  are  rejected  with  a  freedom  that  may  not  find 
general  approval.  The  classification  here  adopted  does  not  pretend 
to  finality  in  its  details,  but  only  to  convenience,  for  the  time 
when  knowledge  of  the  constituent  forms  of  any  group  of  Lamelli- 
cornia  will  even  approach  completeness  is  yet  far  off,  and,  as  new 
forms  reveal  themselves,  apparent  breaks  of  continuity  must  dis- 
appear and  revision  of  the  limits  of  the  groups  which  sysremati- 
sation  renders  necessary  be  continually  repeated.  Genera  and 
larger  divisions  are  therefore  arbitrary  and  their  most  convenient 
limits  must  remain  a  matter  of  opinion.  The  system  which  has 
been  adopted  of  expressing  in  tabular  form  the  most  salient  differ- 
ential characters  of  every  species,  genus  and  larger  division  has 
provided  a  crucial  test  of  existing  groupings  and  entailed  a  con- 
sistency which  is  not  to  be  expected  from  the  short  memoirs  by 


22  INTEODUCTION. 

many  authors  (few  of  them  laying  claim  to  any  comprehensiveness 
or  continuity),  which  form  a  large  part  of  the  literature  of  this 
subject. 

Por  the  purpose  of  accurate  identification  it  is  obviously 
desirable  that  every  group  should  be  distinguished  by  features  of 
both  sexes,  but  unfortunately  in  the  Lamellicornia,  in  which,  more 
than  in  any  other  beetles,  the  most  salient  features  are  seen  in 
the  male  alone,  this  principle  has  been  Aery  frequently  infringed. 
Species  and  genera  have  been  constantly  based  upon  examples  of 
one  sex  only  and  often  without  ascertaining  or  recording  the  sex. 
Sexual  characters  may  be  the  chief  criteria  in  the  discrimination  of 
species,  and  it  may  even  be  necessary  to  separate  forms  of  which 
one  sex  appears  to  us  to  be  without  differential  characters,  but  I 
consider  such  features,  unconfirmed  by  any  other,  quite  inadequate 
for  forming  genei'a  or  superior  divisions.  They  may  be  \aluable 
as  supplementing  more  fundamental,  but  less  obvious  differences, 
but  as  a  rule  they  are  very  inconstant,  and  species  whose  relation- 
ship is  undeniably  very  close  often  display  wide  differences  in  this 
respect.  Genera  which  have  been  sunk  on  this  ground  will  often 
be  found  to  contain  very  few,  or  only  one,  species. 

Wherever  any  marked  external  difference  between  the  two  sexes 
is  found  it  has  been  pointed  out,  and  care  has  been  taken  to  exclude 
from  the  general  descriptions  all  features  distinctive  of  one  sex. 
As  it  sometimes  happens  that  a  species  is  known  only  from  a 
single  specimen,  or  examples  of  one  sex,  it  is  not  always  possible  to 
distinguish  such  features. 

In  order  to  ensure  accurate  nomenclature,  no  effort  has  been 
spared  to  obtain  actual  types  or  co-types  for  examination  whenever 
possible.  Unfortunately  some  have  not  been  traced,  but  mention 
of  the  present  location  of  the  type  has  been  made  m  lien  it  has 
been  ascertained,  and  those  studied  in  the  course  of  this  work  are 
indicated  with  an  asterisk. 

It  should  perhaps  be  mentioned  that  all  descriptions  are  drawn 
from  Museum  specimens  and,  as  regards  colours  at  least,  will 
perhaps  be  found  not  always  to  apply  accurately  to  living  speci- 
mens, owing  to  inevitable  changes  which  take  place  after  death. 
Such  knowledge  as  the  author  has  of  the  insects  in  their  natural 
state  is  derived  from  European  forms  alone,  a  disadvantage  which 
is  to  be  regretted,  although  it  must  be  remembered  that  in  so  vast 
a  region  as  India  only  a  fraction  of  the  species  of  any  large  group 
are  likely  to  come  under  the  observation  of  any  single  individual 
even  with  the  maximum  of  opportunity,  whilst  it  is  in  Europe 
alone  that  that  fauna  can  be  studied  with  even  approximate  com- 
pleteness and  in  relation  to  the  faunas  of  adjacent  regions  and  of 
the  world  in  general. 

The  Lamellicornia  are  divided  into  three  Families  which  may 
be  briefly  distinguished  as  follows  : — 
Antenna?  not  elbowed  nor  capable  of  being 

rolled  up,  the  joints  of  the  club  very  thin 

and  doselv  co-adapted      SCARAB.flEIDiE. 


LAMELLICOBNIA.  23

rolling  up PASSALIDJE. 

Antennae  elbowed,  not  capable  of  rolling  up, 

the  joints  of  the  club  not  very  thin  nor 

closely  co-adapted LTJCANID^. 

Prof.  Ivolbe  regards  the  last  group  as  a  Subfamily  of  the  first 
and  adds  another  family,  Synteliid^,  consisting  of  the  isolated 
genus  Syntelia,  but  the  grounds  of  this  are  debatable  and  I  prefer 
to  retain  the  older  classification. 

In  the  ScAEAB^ici,  which  comprise  an  enormous  majority  of 
the  Lamellicornia,  the  number  of  joints  in  the  club  of  the  antenna 
is  invariably  three,  except  in  some  of  the  Melolonthinse  and  two 
extremely  primitive  genera  Pacliypus  and  Pleocoma,  the  first  in- 
habiting Europe  and  the  second  North  America.  The  family  is 
generally  divided  into  two  great  groups,  according  to  the  position 
of  the  abdominal  spiracles,  but  certain  primitive  forms  are  really 
intermediate  between  the  two,  and  a  South  American  genus, 
Aclopus,  is  stated  to  be  Pleurostict  in  the  female  and  Laparostict 
in  the  male,  that  is,  the  abdominal  spiracles  are  placed  in  the 
chitinous  riugs  in  the  first  and  in  the  connecting  membrane  in  the 
second.  Xo  intermediate  forms  are  found  in  the  Indian  fauna, 
which  comprises  the  following  Subfamilies  : — 

Posterior  spiracles  situated  in  the  dorsal  part  of 

the  chitinous  ventral  segments    PLEUROSTICTI. 

Labrnm  membranous,  not  exserted.

2-i  INTRODUCTION. 

Family    SCARAB^ID^. 

Subfamily  CETONIINiE. 

These  are  among  the  most  familiar  of  beetles  in  the  warmer 
regions  of  the  earth,  being  typically  diurnal,  brightly  coloured  and 
of  moderately  large  size.     Some  of  the  most  brilliant  and  striking 
of  all  animal  forms  are  found  in  the  Subfamily  and,  as  the  species 
are  often  very  abundant  and  make  little  or  no  attempt  at  con- 
cealment, they  attract  more  attention  than  most  other  insects,  both 
in  the  liviiig  state  and  in   collections.      They  may  perhaps  be 
regarded  as  a  group  of  comparatively  late  evolution  and  still  en- 
joying the  maximum  of  vigour  and   prosperity.     In  consequence 
they  form  a  very  homogeneous  assemblage  without  considerable 
gaps  and  without  any  important  structural  variation.     As  a  result, 
classification  is  very  ditficult,  the  component  sections  merging 
almost  imperceptibly  into  one  another.     An  effect  of  the  attrac- 
tiveness of   the  group  is  that  it  has  received  a  special  amount 
of  attention  from  a  very  large  number  of  sj'^stematists  of  every 
kind,  but,  although  the  literature  relating  to  it  is  exceptionally 
large,  it  has  received  very  little  serious  scientific  study.     Of  the 
metamorphoses  and  habits  of  the  species  we  know  lamentably  little, 
and  for  any  comprehensive  classification  it  is  necessary  to  go  back 
to  a  period  ^hen  the  number  of  known  forms  had  reached  only  a 
fraction   of  its  present  size.     The  Monograph  of  the  group  by 
Grory  and  Percheron  published  in  1833,  although  illustrated  with 
copious    coloured    figures,  is   a    most  unsatisfactory  work  which 
probably  introduced  more  confusion    than  it  cleared  up.      The 
admirable  volume  devoted  to  the  subject  by  Burmeister  (Hand- 
buch  der  Entomologie,  vol.  iii,   1842)  is  unfortunately   without 
illustrations,  and  a  further  misfortune  for  the  Indian  fauna  was 
occasioned   by  the   practically   simultaneous  publication    with  it 
of  Westwood's  work  on  "  The  Goliat hideous  Cetouiida?  of  Asia" 
(Arcana    Entomologica,    vol.   i.)   and   of    Blanchard's   "  List    of 
Cetoniidse"   in   the  Paris    Museum.     In   these   works   different 
names  were  in  various  cases  given  independently  to  the  same 
form.      Thus   "Westwood's    genus    Heterorrhina    is    Burmeister's 
Coryphocera  and  Ileterorrh'ma   dives   of   Westwood   was   actually 
described    by    Burmeister   from    the    same    miique    specimen    as 
Alystroceros  dlardi.    In  such  cases  I  have  allowed  the  priority  to 
Westwood,  whose  work  was  published  in  two  parts,  the  second 
appearing  on  the  1st  September  1842,  while  Burmeister's  Preface 
being  dated  September  1842,  may  safely  be  assumed  to  have  been 
unpublished  on  the  first  of  that  month. 

The  number  of  Cetoniin,^  now  recorded  for  the  whole  world  is 
about  2500,  and  of  these  nearly  2o0  are  here  enumerated  as 
Indian. 


CETOXiiisriE.  25 


Structure. 


The  exterior  is  very  bard  and  chitinous,  fi-eqiienth'  covered  witlv 
a  peculiar  bloom,  like  that  of  a  ripe  plum,  and  decorated  with 
spots  or  patches  of  white  or  yellow  consisting  of  a  powdery  sub- 
stance which  appeal's  to  be  of  a  similar  nature  to  hairs  or  scales 
and  usually  occupies  slight  depressions  in  the  integument.  In 
rare  cases  this  substance  has  a  silvery,  golden  or  opalescent  lustre, 
but  it  is  generally  quite  dull.  In  the  small  species  forming  the 
section  Valgini  this  type  of  decoration  is  not  found,  but  the  body 
is  more  or  less  covered  with  scales  of  different  colours,  by  which 
patterns  are  produced. 

As  in  the  Dynastinj^,  Euteli>^e  and  INIeloloxthix.e,  the 
abdomen  is  composed  of  six  segments  ventrally,  the  last  dorsal  one 
is  large  and  exposed,  and  the  posterior  spiracles  are  situated  in 
the  chitinous  dorsal  part  of  the  ventral  segments  and  not  in  the 
flexible  membrane  connecting  the  ventral  and  dorsal  parts  of  the 
abdomen.  A  peculiarity  in  the  structure  of  the  spiracles  is  found 
in  the  Valgixi  and  a  few  members  of  other  sections,  the  last  pair 
of  spiracles,  and  sometimes  in  a  less  degree  the  one  or  two  pairs 
immediately  preceding,  being  placed  at  the  end  of  prominent 
horny  tubercles. 

The  front  of  the  head,  or  clypeus,  is  always  well  developed, 
forming  as  a  rule  a  broad  shovel- like  instrument  and  apt, 
occasionally  in  both  sexes,  but  more  often  in  the  male  alone,  to 
give  rise  to  horns  of  various  forms  and  sometimes  considerable  size. 
In  a  few  cases  the  prothorax  of  the  male  bears  a  similar 
armature. 

The  prothorax  is  typically  fitted  very  closely  to  the  hinder  part 
of  the  body,  generally  having  eitlier  an  excision  in  front  of  the 
scutellum  or  a  prolongation  by  which  the  latter  is  partly  or  entirely 
concealed.  All  the  species  are  active  fliers  and,  except  in  the 
small  section  of  the  Teichiini,  flight  is  accomphshed  in  a  very 
characteristic  manner,  with  which  is  connected  the  most  distinctive 
features  of  their  external  anatomy.  The  elytra  are  not  lifted  high 
and  carried  back  to  back  in  flight,  according  to  the  common  manner 
of  beetles,  but  are  only  slightly  raised  and  the  wings  are  slipped 
out  beneath  their  lateral  edges.  The  elytra  accordingly  only 
wrap  over  the  body  near  the  shoulders  and  are  more  or  less  reduced 
at  the  sides,  sometimes  becoming  quite  narrow  and  distinctly 
exposing  the  lateral  parts  of  the  back.  Together  ^vith  this  com- 
parative immobility  of  the  elytron,  has  been  produced  a  general 
consolidation  of  the  body  and  close  co-adaptation  of  its  parts. 
The  epimera  of  the  mesosteruum  are  so  developed  as  to  fill  the 
angles"  between  the  prothorax  and  the  shoulders  of  the  elytra  and 
the  prothorax  slides  over  the  elytron  and  the  mesothorax,  so  that 
even  when  drawn  forward  it  has  not  free  play  in  all  directions 
but  remains  closely  applied  to  the  hind  body.  There  is  thus  no 
arresting  ridge  at  the  front  of  the  elvtra  and  scutellum  as  in  the 


26  INTKODUCTION. 

most  nearly  related  groups.,  and  the  apparent  size  of  the  scutellum 
changes  with  the  position  of  the  prothorax.  This  feature,  how- 
ever, is  absent  in  the  Trichiixi  and  Valgixi  and  in  a  few  of  the 
remarkable  horned  Cetoxiixi.  Another  peculiarity  of  the  Sub- 
family is  the  pigmentation  of  the  wings,  the  terminal  part  and 
often  the  whole  being  coloured  a  deep  red-brown  or  blue-black. 
This  is  very  unusual  in  beetles,  although  often  found  in  insects  in 
Mhich  the  wings  ai'e  always  exposed. 

The  front  coxa^  do  not  spread  out  in  a  transverse  direction,  as  in 
the  Dynastix.t:,  &c.,  but  are  inserted  vertically,  very  prominent 
and  in  close  contact,  and  the  presternum  is  not  elevated  behind 
them.  The  middle  coxse  are  transverse  and  level  with  the  meta- 
sternum,  the  front  of  which  projects  between  them  and  often  in 
front  of  them,  sometimes  forming  a  long  pointed  or  truncated 
process.  The  end  of  tlie  process  consists  of  an  elevated  part  of 
the  mesosternum  united  to  the  metasternum,  but  the  line  of 
junction  is  not  always  traceable.  The  hind  coxie  are  large,  meeting, 
except  in  the  small  species  forming  the  Valgini,  and  generally 
prominent  at  the  sides  of  the  body  and  visible  from  above.  The 
femora  are  simple  and  differ  little,  although  those  of  the  hind  legs 
are  thickened  or  arched  in  the  males  of  a  few  forms.  The  front 
tibiae  are  generally  toothed  externally,  at  least  in  the  female,  and 
the  teeth  are  never  more  than  three  in  number  except  in  the 
Valgini,  most  of  which  ha^•e  five.  The  posterior  tibiaj  have  often 
an  internal  fringe  of  hairs  and  an  external  .spine  near  the  middle. 
The  tarsi  consist  of  five  simple  joints,  except  in  certain 
Ckemastochilini,  which,  living  in  the  nests  of  Ants  or  Termites, 
have  become  entirely  abnormal  in  many  points  of  their  structure, 
like  many  other  insects  leading  the  same  peculiar  life.  The  claws 
are  always  simple  and  immovable,  with  rare  exceptions  in  the  front 
claws  of  the  males  of  certain  African  forms. 

The  mouth  is  adapted  for  dealing  ouly  with  soft  or  liquid  food, 
except  in  the  Cbemastociiilini,  which  have  the  mandibles  strong 
and  sharp  although  small.  The  labrum  is  reduced  to  little  more 
than  a  vestige,  forming  two  membranous  lobes  entirely  concealed 
in  the  roof  of  the  mouth.  The  maudibles,  except  those  of  the 
Cremastociiilini,  are  thin  and  incapable  of  biting,  consisting  of 
a  blunt  flexible  rod  with  a  membranous  internal  fringe  at  the  base. 
The  maxillaj  are  well-developed,  strong  and  generally  toothed. 
In  typical  Cetoniin.e  they  are  covered  with  long  hairs,  which  form 
terminal  tufts,  often  visible  externally  and  apparently  the  chief 
means  of  collecting  the  sweet  juices  upon  which  the  insects  feed. 
The  mentum  is  very  chitinous,  without  a  distinct  ligula,  and 
generally  bears  long  stiif  hairs.  JJoth  maxillary  and  labial  palpi 
are  3-jointed  and  slender.  In  the  Cremastochilixi  the  mentum 
is  dilated  and  forms  a  kind  of  operculum,  coinciding  with  the 
clypeus  and  shutting  in  completely  all  the  other  organs  of  the 
mouth. 

The  eyes  are  large,  prominent  and  very  finely  facetted,  and  the 
antennai  consist  of  ten  joints,  the  last  three  forming  the  club,  and 
varying  very  little.     The  basal  joint  is  larger  than  the  rest,  and  in 


CETONIIN.i;.

some  Cremastochilini  and  Valgini  is  very  broad  and  serves  to 
enclose  and  protect  the  sensitive  parr  of  the  organ  when  the  head 
is  folded  beneath  the  thorax. 

Sexual  Dimorphism. 

In  several  genera  the  male  bears  a  pair  of  horns  or  antlers  upon 
the  head,  and  there  are  a  few  (although  at  present  no  Indian 
representative  is  known)  in  which  a  single  horn  is  borne  upon 
the  prothorax.  In  Trigonoplwrus  both  sexes  bear  a  process  at 
the  front  of  the  clypeus  and  another  process  upon  the  forehead 
the  latter  differing' in  male  and  female;  while  in  Heterori-hina  an 
appendage  is  always  found  upou  the  forehead  in  the  female,  but 
not  always  in  the  male.  Much  more  frequent  sexual  differences 
are  found  in  the  structure  of  the  legs.  I  have  already  remarked 
that  these  are  almost  always  used  in  the  female  for  digging.  The 
front  tibia  is  of  chief  importance  for  this  purpose,  and  is  accord- 
ingly strong  and  armed  externally  with  teeth,  generally  three  m 
number.  In  many  males  this  function  does  not  exist,  and  the 
tibia  is  less  stout  and  strong  and  the  teeth  reduced  or  quite  absent. 
In  some,  such  as  Jumnos  rucheri  (PI.  I,  fig.  6),  the  whole  leg  is 
greatly  elongated  and  the  tibia  is  fantastically  toothed  on  the  lower 
surface.  The  tarsi  are  very  often  more  slender  in  the  male  than  m 
the  other  sex.  On  the  other  hand  the  hind  legs  are  sometimes 
stronger  in  the  male  than  in  the  female,  as  in  Eucliloropus  lintus. 
A  shght  but  peculiar  feature  is  often  found  in  the  two  spines  at  the 
end  of  the  hind  tibia,  which  are  commonly  short  and  sharp  in  the 
male,  and  longer  and  blunter  in  the  female.  Elongation  of  the  club 
of  the  antenna,  very  general  in  the  males  of  other  subfamilies, 
is  rare  in  the  Ceioniin^.  The  form  of  the  abdomen  very 
frequently  differs,  the  males  having  the  lower  surface  arched  or 
even  deeply  hollowed  out  along  the  middle.  In  females  of  Vahjus 
and  Charitovalfjus  the  end  of  the  abdomen  gives  rise  to  a  long 
slender  style  suggestive  of  the  ovipositor  of  Hymenoptera  and 
other  insects. 

Differences  of  colour  and  pattern  also  occur,  althoughthey  are 
less  common  than  structural  differences.  Generally  their  nature 
has  been  overlooked  and  the  two  sexes  have  been  described  as 
distinct  species,  as  in  various  members  of  the  genera  Macronota 
and  Glyaipliana.  In  such  cases  the  male  is  usually  brightly 
coloured  and  the  female  dull  and  undistinguished.  Thus  in 
Macronota  crucicollis  and  oherthuri,  two  South  Indian  species,  the 
males  are  red  or  black,  decorated  with  an  elaborate  pattern  of 
white  lines,  while  the  females  are  coloured  auuiform  clayey-brown. 
In  the  North-Indian  Heterorrliina  mutahilis  and  ff.  dispar,  the  males 
are  resplendent  in  exquisite  shades  of  green,  blue  or  purple,  and 
the  females  an  unpleasing  dull  brown  or  black.  In  some  of  the 
Valgini,  in  which  the  markings  are  due  to  the  arrangement  of 
different  coloured  scales,  the  colours  are  also  different  in  the  two 
sexes,  and  here  again  the  males  have  brighter  and  more  varied 
colours. 


28  IXTRODLX'TIOX. 

Colour  and  Pattern. 

Few,  if  any,  groups  of  beetles  offer  richer  materials  for  a  study 
of  the  problems  of  colour  and  pattern  than  the  Cetoniinm. 
Black  or  dull-coloured  species  are  exceptional  and  found  only  in 
the  Ckemasxociulixi  and  a  few  genera  peculiar  in  their  very 
retiring  or  jiocturnal  habits.  Some,  however,  are  of  a  highly 
polished  and  lustrous  black,  relieved  with  patches  of  bright  orange, 
red  or  green,  as  in  the  genus  Diceros,  a  sharp  contrast  which  must 
make  them  very  conspicuous  in  almost  any  environment.  In  the 
highly  characteristic  Indian  group  of  the  Heteeokeiiinides  vivid 
greens  predominate  and  the  surface  is  always  very  shining, 
frequently  glassy.  This  colouring  is  very  variable,  and  different 
individuals  of  a  species  may  be  grass  green,  olive  green,  indigo, 
purple,  blue,  black,  fiery  red,  or  golden  green.  Such  shades  may 
always  be  regarded  as  interchangeable  and  of  no  significance  for  the 
purpose  of  classification.  All  the  species,  however,  are  not  equally 
variable,  for  while  some  shade  of  green  is  nearly  always  the  normal 
one,  in  some  species  other  colours  are  almost  ot  equal  frequency,  as 
for  instance  in  Tortjnorrhina  dlstincta  and  Httcrorrhiaa  nigritarsis^ 
and  in  others  they  are  of  rare  occurrence,  as  in  Heterorrhina 
punctatissima  and  most  species  of  Triffonophorus.  Defect  of  pig- 
ment in  all  these  green  species  seems  to  result  in  the  production 
of  fiery  reds,  and  it  is  probable  that  the  red  condition  is  passed 
through  in  the  process  of  attaining  the  full  colouring  of  maturity. 
Experiment  shows  that  it  is  produced  in  dead  specimens  by  the 
chemical  decomposition  which  takes  place  in  the  green  pigment 
upon  prolonged  exposure  to  sunlight. 

In  the  Heteeokrhinides  colour  patterns  do  not  occur,  or  only 
in  a  few  cases  in  tlie  sha])e  of  large  masses  of  yellow  or  black.  In 
the  most  typical  Cetoxiix-E,  represented  by  the  genera  Ceionia, 
Protatia,  C'J inter ia, etc., ])atterus  are  the  rule  and  are  due  to  a  very 
fine  powdery  substance  genei-ally  lying  in  and  filling  depressions 
in  the  surface  and  therefore  less  easily  worn  off  than  is  often  the 
case  with  similar  powdery  or  scaly  adornments.  These  decorations 
are  always  white  or  some  shade  of  yellow,  occasionally  approaching 
red,  and  can  almost  always  be  traced  to  a  primitive  arrangement 
of  spots  which  recurs  over  and  over  again  throughout  the  group. 
The  primary  spots  are  a  ])air  placed  transversely  behind  the 
middle  of  the  pronotum  and  four  behind  the  middle  of  the  elytra 
in  a  transverse,  but  not  a  straight  line.  Secondary,  and  generally 
smaller,  spots  constantly  found  are  a  pair  before  the  middle  of  the 
pronotum,  a  pair  at  the  hind  margin  of  each  elytron,  two  or  three 
at  the  outer  margin,  and  one  or  more  near  the  scutellum  on  each 
side.  The  spots  have  a  marked  tendency  to  lengthen  and  coalesce, 
those  of  the  thorax  longitudinally  and  those  of  the  elytra  trans- 
versely, forming  irregular  bands,  of  which  one  crossing  the  elytra 
beyond  the  middle  is  always  a  prominent  feature.  The  further 
development  of  the  bands  produces  a  complex  irregular  network, 
and  finally,  as  in  Protatia  fusca,  a  fine  cobweb  of  interlacing  pale 


CETONIIN.^E.  29 

lines.  The  inavkiug  is  almost  tihvays  accompanied  on  the  lower 
surface  by  more  massive  light  patches  upon  the  side  pieces  of  the 
thorax  and  the  sides  of  the  first  four  abdominal  segments. 

The  two  types  of  pattern  sometimes  occur  together,  the  super- 
ficial powdery  markings  overlying  an  arrangement  of  two  colours 
in  the  inner  layers  of  the  integument  and  so  producing  a  triple 
colour-scheme,  Tliis  is  frequent  in  the  genus  Macronota,  in  which 
the  evolution  of  pattern  reaches  its  furthest  limit  in  Lamellicorn 
beetles.  In  several  species  of  the  genus  complex  patterns  of 
black  and  red  underlie  still  more  complex  traceries  of  white  or 
yellow.  In  Macronota  m'sus  and  M.  westwoodi  the  pattern  is  pro- 
duced by  a  long  dense  covering  of  black  and  orange  hairs,  which, 
together  with  the  shape  of  the  body,  bring  about  an  extraordinarily 
close  resemblance  to  two  species  of  Humble  Bees  inhabiting  the 
same  district  as  the  beetles.  Few  more  striking,  or  more  obviously 
useful,  instances  of  mimicry  than  these  could  be  found.  In  some 
of  the  other  species  of  the  genus,  entirely  different  in  appearance 
but  closely  similar  in  structure,  a  peculiar  iridescent  sheen  upon 
the  long  narrow  elytra,  the  partly  uncovered  yellow-  or  white- 
banded  abdomen,  and  the  general  form  of  the  body  suggest  a 
mimetic  resemblance  to  wasps  or  bees  which  observation  of  the 
insects  in  nature  may  or  may  not  confirm.  Various  species  of 
CBTONiiN.i:  are  known  to  be  unpalatable  to  birds  and  other  insecti- 
vorous animals,  and  it  can  hardly  be  doubted  that  the  boldly 
contrasted  colours  of  many  species,  such  as  CUnieria  imperialis 
and  Glycosla  tricolor,  are  warning  colours  for  advertising  this 
inedible  quality. 

In  the  ValgijSti  another  type  of  decoration  appears,  the  whole 
or  greater  part  of  the  body  being  covered  with  scales  or  set£e  of 
large  size  relatively  to  that  of  the  body  and  of  more  or  less 
diversified  colours,  ranging  from  white,  through  all  shades  of 
yellow  and  brown,  to  black.  These  scales  or  setae  are  very  liable 
to  abrasion,  leaving  the  underlying  uniformly  black  or  brown 
surface  exposed. 

Hahits  and  Metamorplwses. 

With  the  remarkable  exception  of  a  Tropical  American  genus, 
Inca,  the  larvae  of  which  were  recently  found  by  Dr.  Ohaus  to  have 
the  power  of  climbing  trees,  the  larvae  of  Cetonitn^  do  not  differ  in 
any  important  particular  from  those  of  DrNASTiN^E  or  Rutelin.e, 
so  far  as  they  are  at  present  known.  Like  those  of  nearly  all 
Lamellicornia,they  are  inactive  and  live  concealed, generally  under- 
ground, where  they  feed  upon  roots,  decaying  wood  or  vegetable 
debris.  The  habits  of  the  more  peculiar  genera  of  the  Indian 
fauna  are  still  unknown,  and  the  only  information  vv-hich  I  have 
been  able  to  obtain  on  this  subject  concerns  those  genera  which, 
besides  India,  inhabit  Europe  or  other  parts  of  the  world. 
M.  Fabre*  has  described  the  life-histoi'ies  of  Cetonia,  Proto-tia  and 

*  Souvenirs  Entomologiques,  vol.  viil. 


30  lyXRODUCTION. 

Oxythyrea,  three  genera  common  to  India  and  Europe,  whose 
manner  of  life  seems  almost  the  same.  All  of  these  feed  within 
accumulations  of  decaying  leaves  and  vegetable  refuse,  the  female 
burrowing  into  the  mass  and  depositing  her  eggs  there.  It  is  a 
remarkable  fact,  observed  by  M.  Fabre,  that  this  does  not  take 
place,  at  least  in  Europe,  until  long  after  maturity  has  been 
reached.  The  first  summer  and  autumn  of  adult  life  are  entirely 
devoted  to  the  consumption  of  nectar,  exuding  sap  or  the  juices 
of  ripe  fruit,  and  no  eggs  are  laid  nntil  the  following  year. 

Protcetia  cuprea,  P.,  an  abundant  species  which  ranges  from 
Southern  Europe  to  Northern  India,  prefers  to  de])osit  its  eggs  in 
ants'  nests,  and  apparently  only  selects  other  situations  when 
suitable  nests  are  not  to  be  found.  The  larvaj  are  often  found  in 
numbers  feeding  upon  the  woody  material  composing  the  nests 
of  Formica  rufa  and  F.  pratensis,  and  seemingly  not  interfered 
with  by  the  ovi^ners  of  the  nest. 

Although  provided  with  well-developed  legs  the  larva  moves 
solely  by  contractions  of  the  body  and  generally  upon  its  back. 
The  legs  seem  to  serve  chiefly  for  the  construction  of  the  cocoon, 
which,  after  two  or  three  years  of  larval  life,  is  formed  in  situ  from 
fragments  of  the  food-material  cemented  together  into  a  cell  about 
the  size  of  a  pigeon's  egg  and  plastered  and  smoothed  inside  with 
matter  furnished  by  the  intestine.  One  to  three  months  are 
passed  in  the  pupal  stage  and  then  the  perfect  insect  breaks  open 
the  cocoon  and  makes  its  way  above  ground,  soon  beginning  to 
feed  voraciously. 

In  Protatia  ciiprea  and  other  species  known  to  breed  in  ants' 
nests  there  is  no  special  adaptation  of  structui-e  to  this  habit,  but 
in  others,  in  which  perhaps  this  mode  of  life  is  of  more  ancient 
date  and  more  firmly  established,  the  female  shows  certain 
adaptations,  apparently  enabling  her  better  to  resist  the  ants  while 
depositing  her  eggs  in  the  nest ;  while  the  whole  of  the  Cremasto- 
CHiLiNi  have  acquired  in  both  sexes  peculiar  characteristics  which 
must  indicate  the  adoption  of  the  habit  at  a  very  remote  period. 
In  this  group  the  greater  part  of  the  life  both  before  and  after 
maturity  seems  to  be  spent  in  the  dark  recesses  of  ants'  or  termites' 
nests,  and  adults  as  well  as  larvae  seem  to  feed  upon  the  nest- 
substance.  The  bright  colouring  of  the  generally  light-loving 
Cetoniin.'E  has  given  place  to  uniform  black  or  brown,  the  body 
has  acquired  an  extremely  hard  and  compact  exterior,  and  the 
mouth  IS  adapted  for  dealing  with  solid  food  instead  of  liquids. 
The  mandibles  are  strong  and  sharp  and  the  mentum  completely 
shuts  in  all  the  mouth  appendages,  so  that  the  whole  body  presents 
no  vulnerable  part.  In  many  the  basal  joint  of  the  antenna  forms 
a  stopper  by  which  the  succeeding  joints  can  be  shut  up  between 
the  head  and  the  front  legs,  and  in  the  genus  Callinomes  the  tarsi 
are  reduced  to  only  three  visible  joints,  which  are  so  closely  fitted 
together  as  to  be  capable  of  very  little  movement. 

In  one  genus  of  Ckemastochilixi  {Macvoma)  bright  colours 
prevail  and  the  form  is  less  aberrant  than  in  the  rest,  and,  as 
would  be  expected,  the  species  are  diurnal  and  frequent  flowers,

although  also  found  in  ants'  nests.  Either  there  has  been  a 
reversion  to  ancestral  habits  or  they  have  never  been  entirely  lost. 
One  other  genus  {Sinhplwrus)  is  exceptional  in  having  conspicuous 
white  markings  (conspicuous  when  closely  examined,  that  is,  but 
probably  the  reverse  in  its  usual  environment)  upon  a  shining 
black  background,  and  there  is  reason  for  supposing  that  this  also 
is  less  completely  subterranean  in  habit  than  other  Ceemasto- 
CHiLiNi.  Spilopliorns  cretosus  has  been  found  in  the  nest  of  an  ant, 
but  congeners  inhabiting  Africa  and  having  a  similar  coloration 
are  found  in  birds'  nests,  upon  which  their  larvse  feed,  as  Mr.  Guy 
Marshall  has  observed.  The  coloration  suggests  a  cryptic 
adaptation  to  such  an  environment  and  it  will  probably  be  found 
that  the  two  Indian  species  have,  at  least  partially,  the  same 
habit. 

Several  species  of  Cetonii?^^  in  the  adult  condition  attack  the 
nests  or  hives  of  bees,  opening  the  cells  and  devouring  the  stored 
honey.  Protcetia  opaca  around  the  Mediterranean,  P.  fusca  (an 
Indian  species)  in  Australia,  and  probably  other  species,  cause 
considerable  injury  in  this  way.  Others  are  injurious  on  account  of 
their  habit  of  destroying  the  stamens  of  flowers  and  so  preventing 
the  formation  of  fruit.  AVhether  any  of  them  are  capable  of 
injuring  ripe  fruits  when  in  perfectly  sound  condition,  or  whether 
they  only  take  advantage  of  abrasions  already  existing,  is 
uncertain. 


32  CETOXIIX-E. 

The  Cetoniin.e  consist  of  three  well-defined  Divisions,  them- 
selves sometimes  regarded  as  forming  Subfamilies.  They  are  all 
represented  within  our  region  and  may  be  tabulated  as  follows  : — 

Mesostenial  epimera  dilated  above  and  usually 
reaching   the   dorsal  surface  :    base  of  the 

pronotum  not  meeting  ridges  upon  scutellum  [p.  32.

The  first  Division  consists  of  two  Sections  distinguished  as 
follows : — 

Mandibles  thin  and  not  sharp-pointed  nor  adapted 
for  biting,  furnished  with  a  free  membranous 
inner  lobe Cetoniina,  p.  32. 

Mandibles  strong  and  sharp,  without  a  free  mem- 
branous inner  lobe    Chemastochilixa, 

[p.  198. 


Division  1.    CETONIINI. 

Section  1.  CETONIINA. 

This  section  comprises  the  great  majority  of  the  known  species 
of  Cetoniix.^,  including  all  the  largest  and  most  handsome  forms 
and  those  in  A\hicli  are  found  united  all  the  characteristic  features 
of  the  Subfamily,  viz.  the  feebly  chitinised  mandibles,  brush-like 
maxilla),  ascending  mesosternal  epimera,  and  pronotum  (except  in 
DicranGceplicdus)  sliding  closely  over  the  base  of  the  hind  body 
without  meeting  any  arresting  ridge  upon  the  scutellum  or  elytra. 
In  each  of  the  three  remaining  Sections  one  or  more  of  these 
features  is  absent. 

The  Cetoxiina  are  exceedingly  homogeneous  in  all  essential 
points  of  structure,  forming  a  series  so  nearly  unbroken  that  a 
satisfactory  subdivision  has  never  been  attained.  The  frequently 
great  differences  between  the  two  sexes  and  the  absence  of  marked 
structural  features  in  the  females  make  it  almost  impossible  to 
define  minor  groups  so  as  to  include  both  sexes.  I  have  divided 
the  genera  belonging  to  the  Indian  fauna  into  the  following  groups, 
but  it  should  be  understood  that  the  characters  used  iu  the  tables 
which  follow  are  not  to  be  regarded  as  fundamental  or  applicable 
to  forms  from  other  regions.  They  are  selected  only  as  those  most 
easily  available  for  the  discrimination  of  the  insects  dealt  with  iu 
the  present  work.

Type  in  the  British  Museum. 

Colonel  Bingham,  who  observed  this  very  striking  insect  in 
various  parts  of  Sikkim,  told  me  that  it  is  very  sluggish  and  is 
generally  found  clinging  to  the  trunks  of  trees,  in  which  situation 
it  is  very  inconspicuous.  After  heavy  rains  they  become  active 
and  may  be  cauglit  in  large  numbers.  The  males  do  not  appear  to 
fight  nor  to  make  any  use  of  their  large  antlers,  which  seem,  on 
the  contrary,  to  be  rather  inconvenient  to  them. 


Group  2.  Macronotideh. 

This  Group  consists  of  insects  rather  gracefully,  not  compactly, 
built,  and  generally  much  flattened  above  or  even  depressed  along 
the  middle  hue  of  the  back.  The  pronotum  is  always  more  or 
less  produced  over  the  scutellum  but  leaves  a  considerable  part  of 
it  exposed  ;  and  the  scutellum  itself  is  moderately  long  and  sharp, 
but  not  extremely  acute  as   in   the  Oxtthteetdes  and  Loma- 

PTERIDBS. 

The  sexes  are  sometimes  quite  similar  but  often  differ  very 
strikingly  and  the  differences  may  appear  in  almost  any  part  of 
the  external  anatomy.

The  pronotum  is  rugosely  punctured,  almost  flat,  and  forms  a 
nearly  regular  heptagon.  The  scutellum  and  elytra  have  a  silky 
lustre,  and  the  former  is  acute,  not  very  long,  and  bears  a  few 
setigerous  punctures.  The  elytra  are  gently  sinuated  behind  the 
shoulders  and  taper  from  there  to  the  end,  and  each  has  a  strong 
median  costa  which  is  bent  towards  the  shoulder.  They  are 
moderately  punctured  in  the  anterior  part,  the  punctures  changing 
gradually  to  longitudinal  striolae.  The  apical  angles  are  a  little 
produced.  The  pygidium  is  finely  transversely  rugose  and  the 
metasternimi  and  abdomen  coarsely  rugose,  but  nearly  smooth  along

Mange.  The  Oriental  Region. 

Form  elongate,  with  the  sides  and  end  of  the  abdomen  distinctly 
visible  from  above.  Clypens  long  and  generally  slightly  bilobed  in 
front.  Prolhorax  narrower  than  the  elytra  at  the  shoulders,  with 
a  short  posterior  lobe  not  covering  the  scutellum.  Scutellum 
rather  long.  Elytron  cut  away  behind  the  shoulders  and  distinctly 
narrowed  towards  the  apices.  Pygidium  generally  prominent. 
Mesosternnm  only  slightly  prominent  between  the  middle  coxpe. 
Legs  slender  bnt  not  long,  the  front  tibiae  armed  with  three 
(occasionally  only  one  or  two)  sharp  but  short  teeth.  The  upper 
surface  is  generally  covered  with  a  fine  bloom  which  produces  a 
silky  or  velvety  appearance. 

The  sexes  of  Macronota  frequently  difler  from  each  other  to  a 
very  remarkable  degree,  but  there  is  no  single  extez'ual  feature  by 
which  they  may  be  distinguished.  In  several  species,  e.  g., 
M.  A-vittata,  crucicoUis  and  oherfhuri,  the  colour,  pattern  and  shape 
are  all  difi'erent.  The  form  of  the  prothorax  is  frequently  diflPerent. 
In  most  the  6  is  distinguished  by  a  close  fringe  of  hairs  along  the

inner  edge  of  the  hind  tibia  or  forming  a  thick  brush  near  its 
extremity,  the  hind  tarsi  are  frequently  longer,  and  in  some  there 
is  a  considerable  difference  in  the  length  of  the  antennal  club. 

This  is  one  of  the  most  characteristic  and  peculiar  of  Oriental 
genera.  It  has  been  subdivided  into  numerous  so-called  genera 
according  to  the  phases  of  its  very  variable  outline,  but  these  pass 
into  one  another  by  indefinable  degrees. 

Macronota  elonyata,  G.  &  P.,  although  attributed  by  the 
authors  to  Calcutta,  is  probably  not  an  Indian  species.  The 
only  examples  of  authentic  origin  known  to  nie  are  from  the 
Malay  Peninsula  and  Sumatra. 

Macronota  stictica,  Hope,  said  to  inhabit  ^Mysore,  is  a  Philippine 
species.  I  have  found  the  type  to  be  ide)itical  with  the  later-

decorated  with  yellow  or  orange  pubescent  patches  as  follows  : — 
two  longitudinal  lines  on  the  head ;  a  deeply  impressed  line  at  the 
middle  of  the  pronotum,  not  extending  to  the  front  or  hind  margin, 
and  a  similar  one  on  each  side  reacliing  the  front,  but  not  the  hind, 
margin  ;  a  minute  stripe  on  each  side  of  tlie  apex  of  the  scutellum  ; 
a  spot  at  the  inner  edge  of  each  elytron  near  the  middle  of  the 
suture,  a  similar  one  behind  it,  and  three  short  transverse  bars  at 
the  outer  edge  alternating  with  the  spots.  There  are  also  a  large 
patch  upon  the  pygidium  and  transverse  bars  at  the  sides  of  the 
sternum  and  abdomen,  those  of  the  abdomen  being  visible  upon 
both  the  upper  and  lower  surfaces. 

The  body  is  boat-shaped,  narrowing  greatly  both  in  front  and 
behind,  deeply  channelled  along  the  middle  line  of  the  back  and 
very  smooth  above  and  beneath.  The  pj/f/idium  is  almost  horizontal, 
finely  rugose,  and  thickly  clothed  witli  long  hairs,  and  there  are 
short  erect  setse  upon  the  pale  lines  and  spots.  The  Jiead  is 
strongly  punctured,  except  upon  a  posterior  longitudinal  keel,  and 
the  ch/jyeus  is  bilobed.  The  pronotum  is  very  smooth  and  shining, 
except  in  the  neighbourhood  of  the  pale  lines,  where  it  is  closely 
punctured,  the  sides  are  neai'ly  straight  and  very  divergent  towards 
the  base,  which  is  strongly  lobed  in  the  middle,  and  the  hind 
angles  are  a  little  produced.  The  scutelbnn  is  smooth  and  very 
sharp-pointed.  The  elytra  have  a  few  striae  upon  the  posterior 
half,  adjoining  the  suture,  they  are  conrsely  striolated  transversely 
at  the  sides,  where  they  are  largely  cutaway  behind  the  shoulders, 
strongly  serrated  ])Osteriorly  and  acutely  produced  at  the  apical 
angles.  The  metasternum  and  abdomen  are  slightly  punctured  at 
the  sides  and  very  smooth  in  the  middle,  and  the  sternal  process 
is  rounded  and  prominent.  The  front  tihice  are  armed  with  three 
acute  oblique  teeth,  but  the  uppermost  one  is  sometimes  hardly 
traceable  in  the  male.     The  four  posterior  tarsi  are  rather  thick. 

The  two  sexes  are  almost  alike,  but  the  front  tibite  of  the 
male  are  a  little  more  feebly  toothed,  the  hind  tibia;  bear  a 
conspicuous  fringe  of  yellow  hairs  at  the  inner  edge  and  the  hind 
tarsi  are  rather  longer.

hairs  of  a  golden  orange  colour.  These  are  denuded  from  the 
clypeus,  the  frontal  carina,  the  lateral  margins,  posterior  lobe  and 
dorsal  cariiife  of  the  prothorax  and  a  smooth  elevated  lateral  rid"-e 
on  each  side  of  the  scutellum  in  its  anterior  part.  Each  elytron 
is  ornamented  with  a  large  median  yellow  patch  adjoining  the 
suture,  a  similar  one  behind  it  meeting  a  smaller  apical  patch,  and 
three  small  spots  in  a  hne  at  tlie  outer  margin.  The  mesosternal 
epimera,  the  pygidium  and  the  sides  of  the  sternum  are  thickly 
clothed,  and  there  is  a  row  of  patches  on  each  side  of  the  abdomen. 
The  hairs  upon  the  pygidium  are  long  and  erect  and  form  a  pro- 
jecting tuft  at  the  apex. 

The  body  is  long,  broad  at  the  shoulders  and  tapering  to  both 
extremities,  and  the  whole  median  part  of  the  back  is  deeply 
impressed.  The  head  is  bilobed  in  fi'ont  and  has  a  narrow  longi- 
tudinal median  carina  behind.  The  sides  of  the  proOiorax  are 
slightly  angulated  in  the  middle  and  strongly  converge  in  front, 
the  hind  angles  are  slightly  produced  and  the  basal  lobe  is  strong. 
There  are  two  straight  oblique  carinas  which  meet  in  the  middle  of 
the  front  margin  and  enclose  a  triangular  space  which  is  strongly 
depressed.  The  scutellum  is  very  long  and  acutely  pointed,  and 
the  elytra  are  very  broad  at  the  shoulders  and  strongly  cut  away 
behind  them,  with  the  outer  margins  transversely  rugose  and  the 
posterior  sutural  part  finely  striated.  All  the  uncovered  parts  of 
the  body  above  and  below  are  extremely  smooth  and  shining.  The 
sternal  process  is  short  and  broad.  The  legs  are  slender,  the  j^ront 
tibice  having  three  spinose  teeth. 

The  c5"  has  the  abdomen  narrowly  channelled  beneath.

This  differs  from  the  typical  M.  penidllata  in  having  the  lio-ht 
markings  of  a  lemon-yellow  instead  of  deep  orange,  although  the 
shade  is  not  constant.  The  patches  of  pubescence  are  usually 
rather  smaller  in  this  form,  especially  the  median  patch  of  the  pro- 
thorax,  in  w'hich  patch  the  hind  margin  is  commonly  prominent, 
instead  of  notched,  in  the  middle.  The  scutellum,  on  the  contrary, 
is  generally  more  completelj-  covered  than  in  the  other  form.

small  lateral  spots  on  each  elytron,  one  before  and  one  behind  the 
middle,  a  sutural  pair  of  spots  about  the  middle  of  the  elytron,  a 
similar  pair  placed  behind  the  last,  and  a  transverse  line  near  the 
apex  of  each  elytron.  A  spot  at  the  middle  of  the  pygidium,  the 
edges  of  the  mesosternal  epimera,  and  spots  at  the  sides  of  the 
sternal  plates,  the  hind  coxa?  and  the  first,  second  and  fourth 
abdominal  segments,  are  also  white. 

The  species  is  broad  at  the  shoulders  and  tapers  considerably  to 
the  extremity.  The  head  is  strongly  punctured,  with  a  smooth 
carina  behind  and  the  clypeus  deeply  notched  in  front.  The 
prothorax  is  densely  punctured,  strongly  depressed  behind  and  very 
feebly  lobed.  The  sides  are  divergent  from  front  to  back  and 
scarcely  at  all  angulated.  The  eh/tra  are  shining,  strongly  sinnated 
behind  the  shoulders,  narrowed  to  the  apices  and  rather  strongly 
carinated  along  the  middle,  the  part  external  to  the  carinie  being 
coarsely  rugose.  There  are  large,  not  closely  set,  punctures  at 
the  sides  of  the  metasternum  and  all  over  the  abdomen.

thorax  and  elytra,  partiallv  or  entirely  red,  and  with  yellow 
markings  as  follows: — two  longitudinal  lines  upon  the  head ;  an 
entire  median  line  and  an  almost  entire  lateral  one  upon  each  side 
of  the  pronotum  ;  the  median  line  of  the  scutellum,  and  upon  each 
elytron  a  line  adjoining  the  suture,  beginning  behind  the  scutellum 
and  continued  round  the  apex,  a  curved  discoidal  line  from  the 
shoulder  to  near  the  middle,  a  lateral  line  from  behind  the  shoulder 
to  about  the  middle  and  a  lateral  spot  behind  the  last.  The 
middle  of  the  pygidium,  parts  of  the  sterna,  the  mesosternal 
epimera,  and  broad  lateral  lines  on  the  second,  third  and  fifth 
abdominal  segments  beneath  are  also  yellow. 

It  is  broad  at  the  shoulders  and  rapidly  narrows  towards  the 
extremity.  The  clypeus  is  rather  broad  in  front  and  distinctly 
excised  at  the  middle.  The  prothora.v  is  broadest  behind,  the  sides 
scarcely  angulated  before  the  middle,  the  posterior  angles  being 
almost  acute.  The  disc  is  strongly  depressed  along  the  middle 
and  the  posterior  lobe  strong.  The  whole  upper  surface  is  shining

reflexed  and  almost  straight.  The  prothorax  forms  an  almost 
regular  heptagon,  the  sides  being  strongly  angulated  in  the 
middle  and  neai'ly  parallel  behind,  and  the  posterior  lobe  rather 
strong.     The  elytra  are  gently  sinuated  behind  the  shoulders. 

This  insect  rather  strongly  resembles  the  female  of  M.  quadri- 
vittata,  Schaum,  but  the  form  of  the  clypeus  renders  it  a  very 
easily  distinguished  species.

inconspicuous  pale  3'ello\v  spots,  viz.,  a  very  slight  transverse  one 
at  the  lateral  margin  before  the  middle,  a  larger  one  behind  the 
middle,  and  a  minute  intermediate  sutural  one.  A  large  round 
yellow  patch  occupies  the  greater  ])art  of  the  surface  of  the 
pygidium. 

The  shape  is  long  and  narrow.  The  djipens  is  long,  with  the 
anterior  margin  recurved  and  straight.  The  vertex  is  strongly 
keeled  and  the  pubescence  of  the  head  and  thorax  is  longer  than 
that  of  the  elytra.  The  sides  of  the  prothorax  are  considerably 
narrowed  from  the  middle  forwards  and  parallel  behind.  The 
posterior  part  is  depressed  and  the  basal  lobe  is  rather  pointed  but 
not  long.  The  ehjtra  are  depressed  along  the  suture  and  the 
costse  are  strong  and  smooth  at  their  summits.  The  lateral 
margins  are  strongly  sinuated  behind  the  shoulders.

Black,  with  the  legs  red  and  the  whole  body,  except  the  middle 
of  the  abdomen,  thickly  clothed  with  long  erect  hairs  of  a  deep 
brown  colour,  except  those  on  the  legs,  and  a  broad  transverse 
band  crossing  the  elytra  near  the  middle,  which  are  tawny.  The 
hairs  upon  the  pygidium  and  at  the  sides  of  the  abdominal 
.segments  are  sometimes  also  tawny. 

The  form  is  robust  and  the  whole  aspect  is  extremely  like  that 
of  a  Humble  Bee.  The  ehipeus  is  not  densely  hairy  and  is  slightly 
notched  at  the  end.  The  prothora.v  is  rather  globose,  not  obviously 
depressed  behind  and  only  feebly  lobed.  The  dijtra  are  thickly 
hairy,  but  with  the  longitudinal  heel  upon  each  smooth.  The 
lateral  margins  are  strongly  sinuated  behind  the  shoulders.  The 
front  and  middle  tlliuv  are  short  and  broad  and  both  are  very 
strongly  tridentate  at  their  outer  margins.

In  its  form,  colouring  and  thick  hairy  clothing  this  curious 
species  departs  widely  from  its  generic  type,  but  the  divergence 
is  superficial  and  obviously  mimetic.  It  has  the  closest  possible 
resemblance  to  a  Huinble  Bee  {Bombus  eximins,  Lep.)  which  is 


MACEONOTA.  49 

very  common  in  the  districts  in  which  the  beetle  has  been  found. 
In  the  bee  the  body  fur  is  black,  except  at  the  tail,  aud  that  of  the 
legs  briglit  orange.  This  is  exactly  imitated  by  the  beetle,  but  the 
latter  has  also  a  few  long  light  coloured  hairs  upon  the  back,  which 
produce  the  effect  of  the  reflected  light  from  the  folded  wings  of 
the  bee.  AVlien  basking  in  flowers  after  the  manner  of  its  kind 
there  can  be  no  doubt  that  it  could  only  be  distinguished  from  its 
model  by  a  very  close  scrutiny. 

A  genus  was  formed  by  Westwood  for  this  species,  but  the 
discovery  of  other  hairy  forms  has  bridged  the  apparently  wide 
gap  by  which  it  was  separated  from  its  allies.  Divergences 
mimetically  produced  are  always  misleading  in  classification,  and 
the  actual  structural  differences  between  these  hairy  Macronotce 
are  quite  as  great  as  any  by  which  they  are  separated  from  the 
more  normal  forms.

Bombodes  westwoodi,  Thorns.,*  Arch.  Ent.  i,  1857,  p.  284,  pi.  14,  fig.  2. 

Black,  with  the  extremities  of  the  elytra,  the  pygidium,  the  hind 
tibite  and  the  middle  and  hind  tarsi  very  dark  chestnut-red — the 
whole  body  and  legs,  except  tlie  middle  of  the  metasternum  and 
abdomen,  clothed  with  long  ei'ect  hairs,  those  on  the  anterior  half 
of  the  body  and  a  postmedian  transverse  band  upon  the  elytra 
being  black,  those  upon  the  sides  of  the  metasternum  aud  abdomen, 
the  iiind  legs  and  a  median  transverse  band  upon  the  elytra  yellow, 
and  those  at  the  extremities  of  the  elytra  and  the  pygidium  tawny 
red.  There  are  long  and  thick  tufts  of  black  hair  at  the  shoulders 
and  towards  the  extremity  of  each  elytron,  a  whitish  spot 
(generally  more  or  less  triangular)  beyond  the  middle  of  each 
outer  margin,  and  a  short  inconspicuous  transverse  line  before  the 
middle  of  the  suture. 

It  is  much  more  elongate  than  M.  ursus,  Westw.,  and  the  hairy 
clothing  is  less  uniformly  long.  The  legs  are  less  densely  clothed. 
The  whole  upper  surface  is  finely  rugose,  but  there  is  a  well-marked 
smooth  longitudinal  carina  upon  each  elytron.  The  clypeus  is  long 
aud  feebly  bilobed,  the  prothorax  much  broader  than  it  is  long, 
with  the  sides  strongly  angulated  a  little  before  the  middle,  the 
base  broadly  lobed  and  distinctly  depressed  at  the  middle,  and  the 
■eli/tra  strongly  sinuated  behind  the  shoulders.  The  front  tihia  is 
broad  aud  very  strongly  tridentate,  and  the  middle  tibia  has  a  single 
strong  spine  at  tlie  middle  of  the  outer  edge.

abdomen,  one  above  and  two  beneath. 

The  form  is  short  and  stout.  The  ch/peus  is  rather  long  and 
strongly  notched  in  the  middle.  The  protJiorax  is  distinctly 
broader  than  long,  coarsely  punctured  all  over  and  moderately

Bronze,with  red  and  green  reflections,  the  elytra  reddish  with,  more 
or  less  of  the  central  part  obscure ;  decorated  with  slight  Avhitish 
markings,  consisting  of  two  short  lines  upon  the  head,  a  marginal 
line  on  each  side  ot  the  prothorax  and  a  median  V-shaped  mark 
united  to  the  marginal  lines  at  the  front  angles  (but  sometimes 
absent),  a  fine  line  bordering  the  scutellum,  two  minute  lateral 
spots  (one  before  and  the  other  beyond  tiie  middle),  and  an  apical

transverse  bands  on  each  side  of  the  abdomen. 

This  is  a  rather  long  and  narrow  insect.  The  head  is  strongly 
punctured  except  upon  the  frontal  carina.  The  clypetts  is 
moderately  long  and  strongly  bilobed  in  front.  The  2->rothoraa'  is 
coarsely  punctured,  thinly  setose  at  the  sides,  slightly  depressed

and  rather  strone;ly  lobed  behind,  and  the  sides  are  strongly 
angulated  near  the  middle  and  nearly  parallel  behind.  The 
scutellum  and  elytra  have  a  silky  bloom,  and  the  latter  are  strongly 
sinuated  at  the  sides  and  taper  considerably  towards  the  extremities. 
The  costse  are  not  strong.  The  pygidium  is  rugose  and  setose  and 
the  mesosternum  is  rather  produced  but  not  acuminate. 

In  the  S  the  hind  tibiae  have  a  thick  fringe  of  yellow  hairs 
along  the  inner  edge,  the  abdomen  is  longitudinally  grooved  and 
upon  the  fourth  segment  a  tuft  of  long  hairs  occurs  in  the  groove. 
The  depressed  part  of  the  prothorax  is  opaque  in  this  sex. 

The  $  has  the  prothorax  uniformly  shining  and  its  sides  slightly 
converging  towards  the  base.

transverse  lines  on  each  side  of  the  abdomen  white. 

The  form  is  rather  short  and  stout ;  the  head  thickly  punctured 
and  deeply  notched  in  front,  with  a  strong  carina  behind.  The 
prothorax  is  rather  broader  than  long,  thickly  punctured,  de- 
pressed behind,  and  with  a  well-developed  posterior  lobe.  The 
sides  are  straight  and  slightly  converging  behind  and  abruptly  but 
obtusely  angulated  before  the  middle.  The  elytra  are  strongly 
sinuated  at  the  sides  behind  the  shoulders  and  narrowed  towards 
the  apices  and  the  costae  are  not  very  prominent.  The  antennal 
club  is  very  short  in  both  sexes. 

The  prothorax  of  the  male  is  velvety,  the  hind  tibiae  have  a  long 
fringe  of  golden  hairs  towards  their  extremities,  and  the  hind  tarsi 
are  considerably  longer  than  those  of  the  female.  The  abdomen

This  is  another  species  in  which  the  sexes  are  strikingly 
different  and  have  not  hitherto  been  associated,  although  they  have 
been  found  together  in  several  different  localities.  The  pronotum 
of  the  male  is  generally  entirely  black,  but  there  is  sometimes  a 
fine  marginal  white  line  upon  the  anterior  half.  The  male 
specimens  from  Thagata  (in  the  Genoa  Museum)  are  without  the 
white  band  upon  the  pygidium. 

The  name  of  the  species  is  evidently  due  to  a  mistake  in  its 
habitat.  The  type  is  said  to  have  inhabited  Ceylon,  but  that 
locality  cannot  be  accepted.

It  is  probable  that  the  un known  male  diifers  considerably  from 
the  female  above  described.  The  light  markings  are  no  doubt 
brighter  in  colour  and  more  sharply  defined  and  some  difference  in 
shape  may  also  be  expected.

The  male  is  silky  black  ornamented  with  scattered  grey  markings 
and  witli  the  elytra  occasionally  partly  red ;  the  female  is  very 
opaque,  with  the  elytra  brick-red  and  the  whole  upper  surface 
covered  with  a  buff-coloured  earthy  clothing,  except  the  head,  upon 
which  there  are  two  longitudinal  white  lines. 

This  is  a  rather  small  species  of  moderately  elongate  shape. 
The  eyes  are  very  prominent  and  the  clypeus  much  dilated 
anteriorly  and  feebly  emarginate.  The  protlwrnx  is  about  as  broad 
as  it  is  long,  with  the  sides  parallel  behind,  the  hind  angles  very 
obtuse  and  the  posterior  lobe  feeble. 

(S .  The  antenual  club  is  a  little  longer  in  the  male  than  in  the 
female,  but  the  abdomen  is  not  grooved  beneath.  The  grey 
markings  consist  of  two  longitudinal  lines  upon  the  head ;  a 
lateral  line  at  each  side  of  the  prothorax  extending  from  near  the 
hind  angle  to  beyond  the  middle,  a  pair  of  spots  near  tlie  middle 
of  the  base  and  a  V-shaped  mark,  sometimes  open  behind,  ex- 
tending from  the  front  margin  to  beyond  the  middle  of  the  disc  ; 
the  anterior  half  of  the  scntellum  and  the  mesosternal  epimera ; 
an  iri-egular  sutural  patch  at  the  middle  of  the  elytra,  a  common 
CC-shaped  mark  at  their  apices,  and  rather  indefinite  lateral 
markings ;  the  base  and  middle  of  the  pygidium,  and  two  lines  of 
large  spots  on  each  side  of  the  abdomen  beneath. 

The  female  is  almost  uniformly  buff-coloured,  but  may  exhibit 
a  pair  of  indistinct  dark  spots  at  the  elytral  suture,  and  the  earthy 
covering  of  the  pygidium  is  sometimes  divided  into  three  masses. 

The  original  descriptions  of  the  above  references  apply  to  the 
male  alone.

M.  crucicoUis,  Lansb.,  except  that  I  have  seen  uo  specimens  with 
red  markings.  It  is  rather  larger  and  broader,  and  the  upper 
surface  is  more  glossy.  The  clypetis  is  rather  more  deeply  notched 
and  less  widened  anteriorly,  and  the  eyes  are  less  prominent.     The

bind  angles  of  the protltorax  are  a  little  more  prominent  and  the 
posterior  lobe  rather  more  pronounced.  The  posterior  margins  of 
the  ventral  segments  of  the  male  are  decorated  laterally  with 
narrow  white  bands,  the  inner  ends  of  which  expand  and  become 
confluent. 

The  sexes  differ  little  except  in  coloration,  in  which  there  is  no 
similarity.  The  male  is  silky  indigo-black  with  white  markings, 
consisting  of  two  narrow  longitudinal  lines  upon  the  head ;  two 
sinuous  longitudinal  lines,  continuous  from  the  anterior  to  the 
posterior  margin,  at  the  middle  of  the  prothorax,  and  a  marginal 
line  on  each  side  not  reaching  the  hind  border ;  the  anterior  part 
of  the  scutellum  ;  three  or  four  spots  near  the  lateral  edge  of  each 
elytron,  a  large  sutural  patch,  an  M-shaped  mark  behind  the  last, 
and  a  small  apical  band  upon  each.  The  pygidium  has  a  narrow 
median  white  line. 

The  female  has  two  narrow  yellow  lines  upon  the  head,  and  the 
rest  of  the  upper  surface  is  covered  with  a  tawny  earthy  matter 
which  is  more  or  less  denuded  at  the  shoulders  and  on  the  costac  of 
the  elytra,  and  usually  leaves  also  two  bare  black  spots  on  the 
pygidium.

the  middle,  and  with  pale  markings  which  are  bright  yellow  in  the 
male  and  greyish  and  rather  indistinct  in  the  female. 

The  body  is  moderately  elongate,  and  strongly  channelled 
down  the  middle  of  the  back.  The  eyes  are  prominent,  the  clupeus 
considerably  dilated  anteriorly  and  distinctly  emarginate.  The 
protliontx  is  about  as  broad  as  it  is  long,  the  sides  nearly  parallel 
behind  and  the  posterior  lobe  feeble.  The  sides  of  the  elytra  are 
rather  strongly  excised  behind  the  shoulders. 

c? .  The  ochreous  markings  form  two  longitudinal  lines  upon 
the  head  ;  a  V-shaped  median  mark  upon  the  pronotum  extending 
from  the  front  margin  to  beyond  the  middle,  a  curved  lateral  line, 
generally  interrupted,  extending  from  the  median  angulation  of 
the  side  margin  to  the  middle  of  the  base,  and  occasionally  uniting 
with  the  V-shaped  mark;  the  whole  periphery  of  the  scutellum  ; 
a  small  spot  below  the  shoulder  of  each  elytron,  a  larger  one  at 
the  middle  of  the  suture  and  a  transverse  apical  line.  The  middle 
of  the  pygidium  and  the  margins  of  tlie  abdominal  segments  at 
the  sides  are  also  broadly  ochreous.  The  club  of  the  antenna  is  a 
very  little  longer  in  the  male  tlian  in  the  female. 

The  legs  are  frequently,  but  not  invariably,  red  in  the  male  and 
black  in  the  female.  The  latter  is  similar  to  the  male  but  the 
pale  markings  consist  of  a  greyish  pubescence  much  more  indefinite 
than  the  yellow  pattern  of  the  other  sex.

central  part  black — the  surface  ornamented  with   pale  markings 
which  are  bright  yellow  in  the  male  and  dull  yellow^  in  the  female. 

It  is  a  large  species,  of  rather  narrow  elongate  shape,  and 
strougly  sulcate  along  the  middle  line  above.  The  chjpeus  is 
distinctly  notched  in  front,  the  proUiorax  relatively  small  and 
rather  transverse,  and  the  elytra  are  striated  near  the  suture, 
rugose  at  the  sides  and  apices,  with  the  lateral  margins  strongly 
cut  away  behind  the  shonlders.  The  i^ygidium  is  rugose  and, 
like  the  sides  of  the  body  beneath,  thinly  clothed  with  tawny 
hair.     The  club  of  tlie  antenna  is  very  short. 

S '  The  upper  surface  is  opaque,  with  bright  orange  or  yellow 
markings  arranged  as  follows  : — two  longitudinal  lines  upon  the 
head,  four  upon  the  prothorax,  of  which  the  two  internal  ones 
are  complete  and  rather  farther  apart  at  the  front  than  at  the 
hind  margin,  the  two  outer  ones  short  and  directed  inwards 
from  the  lateral  angulation,  a  common  spot  at  the  middle  of  the 
elytral  suture  and  a  lateral  one  on  each  side  behind  the  shoulder 
There  are  also  one  or  three  spots  upon  the  pygidium  and 
narrow  bars  at  the  sides  of  the  ventral  segments.  The  prothorax 
is  punctured  and  finely  setose,  with  its  sides  parallel  behind 
and  the  basal  lobe  moderately  strong.

and  in  addition  to  the  common  elytral  spot  the  greater  part  of 
the  surface  of  the  elytra  (except  the  longitudinal  costoe)  is 
irregularly  sprinkled  with  yellow.  It  is  shining,  elongate,  moder- 
ately broad  at  the  shoulders,  and  rather  depressed  above,  with  a 
well-raised  smooth  costa  upon  each  elytron.  The  prothorax  is

mesosternal  epimera,  the  sides  of  the  sternal  plates  and  large 
irregular  patches  at  the  sides  of  the  abdomen  are  of  the  same 
colour. 

It  is  a  rather  robust  species,  flattened  above.  The  clypeus  is 
strongly  notched  in  front  and  carinated  behind.  The  2i'>'onotuni 
is  very  finely  and  densely  punctured  and  clothed  with  micro- 
scopically fine  setae.  The  sides  are  not  angulated  but  are  arcuate 
in  front  and  straight  behind,  in  the  S  very  slightly  diverging 
and  in  the  $  nearly  parallel.  The  posterior  part  of  the  disc  is 
strongly  depressed  in  the  middle  and  the  lobe  is  very  short  and 
broad.  The  sides  of  the  elytra  are  moderately  sinuated  behind 
the  shoulders  and  narrowed  to  the  ends.  There  is  a  strongly 
marked  carina  down  the  middle  of  each,  the  internal  portion  is 
rather  shining  and  the  external  portion  finely  rugose  and  opaque. 
The  abdomen  is  rather  strongly,  but  not  thickly,  punctured.

p.  560. 

Black,  with  brick-red  patches  upon  the  elytra,  and  decorated 
with  pale  yellow  markings. 

It  is  very  narrow  and  elongate  and  only  slightly  tapering. 
The  head  is  relatively  rather  broad,  with  a  strong  longitudinal 
keel  behind  and  distinctly  sinuated  at  the  front  margin.  The 
prothora.v  is  coarsely  granulated,  the  posterior  part  depressed  and 
the  lobe  very  slight,  so  that  the  scutellum  appears  very  long. 
The  sides  of  the  eh/tra  are  only  very  gently  sinuated  and  the 
costse  are  moderately  strong.     The  legs  are  slender. 

d" .  There  are  two  longitudinal  pale  lines  upon  the  head,  a 
median  line  upon  the  pronotum,  bifurcating  in  front,  but  not 
reaching  the  anterior  margin,  a  broad  longitudinal  line  upon  the 
scutellum,  constricted  or  interrupted  in  the  middle,  a  patch  at 
the  middle  of  the  elytral  suture,  two  lateral  spots  and  an  apical 
one  upon  each  elytron,  and  patches  at  the  middle  of  the  pygidium, 
the  mesosternal  epiniera  and  the  sides  of  the  sternum  and 
abdomen.  The  prothorax  is  broadest  at  the  base  and  its  sides 
are  strongly  angulated  before  the  middle.  The  club  of  the 
antenna  is  very  long  and  tlie  abdomen  strongly  excavated 
beneath. 

The  $  is  relatively  longer,  the  prothorax  is  nearly  circular  in 
shape,  and  the  antennal  club  and  the  hind  tarsi  are  shorter. 
The  yellow  markings  are  similar  to  those  of  the  male,  but  the 
prothorax  has  only  a  short  longitudinal  line  at  the  posterior  part 
and  the  pygidium  is  immaculate.

circular  iu  shape,  with  all  the  angles  almost  obsolete,  and 
moderately  depressed  behind.  The  elytra  have  a  silky  sheen  and 
each  has  a  strong  costa  and  is  feebly  siuuated  beliind  the  shoulder. 
The  front  tibia'  have  each  three  slight  teeth,  and  the  four  jyoaterior

The  locality  Mysore  attributed  to  the  typical  specimen  is

ilistinct. 

Group  3.  Heterorkhixides. 

This  group  contains  the  majority  of  the  Cetoniinj^  in  which  tlie 
head  bears  horns  or  processes.  The  latter  are  very  varied  in  form 
and  are  sometimes  peculiar  to  the  male,  sometimes  ])ossessed  by 
both  sexes,  and  in  some  of  their  minor  forms  confined  to  the 
female.  The  front  tibia}  of  the  male  are  almost  always  unarmed 
externally  and  those  of  the  female  toothed.  Another  sexual 
difference,  of  a  very  unusual  kind,  is  found  in  the  maxillse,  those 
of  the  female  having  at  the  end  of  the  lower  lobe  a  sharp  tooth, 
which  is  absent  or  blunt  in  the  male. 

Most  of  the  species  are  very  smooth  and  shining,  and  brilliantly 
but  uniformly  coloured,  bright  green  being  the  predominant 
shade.

The  upper  surface  is  coriaceous  and  moderately  shining.  The 
prothorax  is  transverse,  with  the  sides  almost  parallel  from  the 
hind  angles  to  beyond  the  middle  and  broadly  rounded  in  front, 
the  anterior  angles  being  obliterated  and  the  front  margin  a  little

(5  .  The  cephalic  horns  together  form  about  three-fourths  of 
the  circumference  of  a  circle.  The  tips  are  blunt  and  strongly 
recurved,  and  a  short  lateral  branch  is  given  ott'  shortly  before 
them.  The  prothoracc  is  rather  opaque  and  strongly  inflated 
above,  leaving  a  narrow  flattened  margin  on  each  side.  The 
abdomen  is  a  little  hollowed  beneath.

The  genus  Ct/phonocejdKdus  was  based  upon  a  single,  poorly 
developed,  male  specimen,  and  the  only  other  individual  hitherto 
described  (Dupont's  type)  is  a  female  which  has  been  accepted  as 
that  of  Narijchis  OjKdus.  The  figure  agrees  well  \\'\{\\  females  of 
the  present  species  which  I  have  examined,  and  Dupont's  state- 
ment that  the  tarsi  are  longer  than  those  of  K.  ojxdvs  seems  to 
nie  to  exclude  the  possibility  of  its  belonging  to  that  species  as 
Westwood  believed. 

A  good  series  of  C.  olivacevs  has  been  collected  by  Mr.  II .  L. 
Andre wes  and  Capt.  A.  K.  "Weld  Downing,  and  the  latter  has 
supplied  some  interesting  facts  regarding  its  habits,  Wlien 
sitting  in  the  branches  of  a  tree  much  frequented  by  it,  with  a 
view  to  capturing  specimens,  he  has  often  seen  two  males  fighting 
on  the  flowers.  "  They  get  their  horns  locked  together,  and  one 
ends  by  knocking  the  other  buzzing  down  the  tree.  The  one 
knocked  down  frequently  returns  to  the  attack,  flying  round 
until  he  finds  his  original  enemy,  and  goes  for  him  again.  They 
lower  their  heads  and  raise  them  sharply  when  fighting,  and  their 
horns  can  be  heard  five  yards  away  knocking  against  each  other." 
Capt.  Downing  has  a  couple  of  male  specimens  with  the  tip  of  a 
horn  broken  off,  probably  in  such  encounters.

px'ojecting  forwai'd  over  the  excavation  from  between  the  eyes. 
The  pronotum  is  very  lightly  punctured  in  the  middle  and  more 
closely  and  coarsely  at  tlie  sides.  It  is  strongly  transverse,  with 
the  sides  rounded  and  not  augulated,  bordered  by  an  impressed 
raargiual  line  which  is  discontinued  at  about  the  posterior  \  ot" 
its  length,  and  the  mesosternal  epimera  are  almost  covered  by  the 
produced  hind  angles.  The  scatelJum  is  shortly  triangular  and 
moderately  sharp  at  the  apex.  The  e^j/tra  have  rather  feeble  rows 
ot"  irregular  punctures  and  are  feebly  sinuated  at  the  sides  and 
acute  at  the  apical  angles.  The  pygidlam  is  very  coarsely  punc-

curved.  There  are  large  but  scattered  punctures  ou  the  meta- 
sternum  aud  legs,  and  all  the  punctures,  both  above  and  beneath, 
are  black-pigment(>d.  The  legs  are  moderately  stout  and  the  front

and  slender  horns  spring  from  its  sides  just  in  front  of  the  eyes. 
They  are  flattened  and  nearly  parallel,  except  at  the  tips,  where 
they  are  a  little  incui-ved  and  bluntly  i-ouuded.  The  prothorax  is 
narrowed  in  front,  and  the  elytra  are  more  spinose  behind  than 
in  the  female.  The  club  of  the  antenna  is  a  little  longer.  The 
front  tibiae  are  quite  simple,  aud  the  abdomen  is  channelled  along 
the  middle  beneath.

'Type  in  the  Paris  Museum,  diardl  having  been  described  from 
the  same  specimen  ;  type  of  miirata  in  the  British  Museum. 

This  beautiful  beetle,  although  discovered  so  long  ago  as  1815, 
is  extremely  rare,  and  has  been  the  subject  of  much  discussion. 
Only  a  single  specimen  of  the  c?  (the  original  specimen  in  the 
Paris  Museum)  is  yet  known.  I  have  been  able  to  make  a  careful 
comparison  of  this  with  the  two  female  specimens  from  Penang  in 
the  British  Museum  to  which  the  name  Heterorrhina  miirata  was 
given  by  Wallace,  and  find  that  they  agree  so  exactly  in  all  points 
but  the  armature,  that  1  have  associated  them  as  a  single  species 
almost  without  hesitation.  I  am  not  convinced,  though,  that  the 
male  was  actually  brought,  as  supposed,  from  Bengal,  and  M.  Lesne, 
of  the  Paris  Museum,  tells  me  that  MM.  Diard  and  Duvaucel,  its 
discoverers,  did  not  collect  only  within  the  Indian  borders  and 
that  the  localities  in  which  their  specimens  were  found  were  not 
recorded  with  any  precision.  It  is  possible  therefore  that  this 
species  may  not  really  belong  to  the  Indian  fauna.  It  is 
also  possible  that  it  may  be  found  in  Lower  Burma  but  not  in 
Bengal. 

Dr.  Ivraatz  discussed  this  species  at  length  (Deutsche  Ent. 
Zeitschr.  1892,  p.  370),  and  concluded  that  the  male  type-specimen 


74  CETOXIIN^. 

was  a  compound  one,  having  had  the  head  of  a  quite  different 
species,  probably  Diceros  peteli,  attached  to  it.  It  is  true  that  the 
head  of  this  specimen  has  at  some  time  been  detached  and  re-fixed, 
but  it  is  not  the  head  of  D.  peteli,  and  there  is  no  reason  to  consider 
it  other  than  the  original  one.

Dicevos  gracilis,  Janson,  The  Entomologist,  vol.  xlii,  1009,  p.  22o. 

Shining  black,  with  the  pygidium,  last  ventral  segment  and 
lateral  margins  of  the  prothorax  frequently  a  very  deep  blood-red, 
the  red  thoracic  margin  being  broadly  produced  inwards  just 
before  the  base.  Each  elytron  is  decorated  with  a  very  pale 
yellow  rectangular  median  patch,  not 
quite  twice  as  long  as  it  is  broad,  and 
separated  from  the  outer  edge  by  an 
extremely  fine,  and  from  the  inner  edge 
by  a  moderately  broad,  black  line. 

This  is  a  very  small  species  of  the 
usual  elongate  shape,  but  rather  strongly 
jninctured  above.  The  head  is  closely 
puncturedand  thech/peus  simple,  rounded, 
and  reflexed  at  the  margin.  'Yhe  jn-ouotum 
is  very  convex  and  distinctly  punctured 
all  over,  with  a  series  of  large  punctures 
Fig.  IS.— JJiWro.'i  gracilis,  closely  collected  in  a  transverse  linear 
depression  on  each  side  before  the  base ; 
the  sides  are  gently  curved  and  finely  margined  and  the  hind 
angles  prominent.  The  scutellum  is  short  and  feebly  punctured, 
and  the  elytra  are  evenly  punctured  in  regular  rows  which  do  not 
quite  reach  the  extremity ;  the  apices  are  a  little  rugose.  The 
jvjgidluni  is  finely  transversely  strigose,  the  met((sternuya  very 
coarsely  and  sparsely  punctured  at  the  sides  and  smooth  in  the 
middle,  and  the  abdomen  coarsely  punctured  at  the  sides  and 
(in  the  $  )  more  finely  and  closely  in  the  middle.

Type,  P.  luimiltoni,  Westw. 

Itanr/e.  Burma. 

Prothorax  about  as  broad  as  it  is  long,  distinctly  narrower  than 
the  elytra  across  the  shoulders  and  almost  parallel-sided  behind, 
^\'ith  the  base  very  fe«bly  emarginate  before  the  scutellum. 
8cutellum  very  short,  scarcely  as  long  as  its  breadth  at  the  base, 
with  the  sides  bisiuuate  and  the  apex  very  acute.  Elytra  ratlier 
straight-sided,  narrowing  from  base  to  apex,  with  the  shoulders 
prominent  and  the  margins  a  little  sinuated  behind  the  shoulders. 
Mesosternum  produced  into  a  moderately  long,  sharp,  conical 
process.  Maxillae  moderately  long,  strougly  tri-dentate.  Mentum 
broad  and  fiat,  Avith  the  front  margin  nearly  straight  and  tlie 
posterior  part  dilated. 

5  .  Head  broad,  excavated,  Avith  a  bifid  horizontal  process  from 
the  vertex  overhanging  the  cavity  and  the  clypeus  not  reflexed  at 
the  margin,  broadly  excised,  with  the  angles  rather  sharp.  Legs 
robust,  with  the  front  tibise  broad  and  armed  with  three  similar 
oblique  teeth. 

Although  this  is  a  very  isolated  genus,  it  is  impossible  properly 
to  indicate  its  generic  chai'acters,  for  the  male,  which  in  all  proba- 
bility differs  greatly  from  the  female,  is  entirely  unknown  and  it 
cannot  be  determined  x'i  hat  features  are  peculiar  to  one  sex.  It 
may  even  prove  to  belong  to  a  diff extent  group  from  that  in 
which  it  is  here  provisionally  located.  The  single  type-specimen, 
although  discovered  more  than  half  a  ceuturj^  ago,  still  remains 
the  only  known  representative  of  its  genus.

The  body  is  moderately  elongate  and  rather  flat,  w  ith  the  lower 
surface  aud  the  pygidium  clothed  with  minute  decumbent  grey 
hairs.     The  head  is  broader  than  it  is  long,  coarsely  punctured 
and  thinly  setose.     It  is  excavated  above,  the  hind  margin  of 
the  excavation  gives  rise  at  the  middle  to 
two  coalescing  processes  projecting   hori- 
zontally  forward,    and    the    front    of   the 
eh/pens  is    arcuately  excised,  with    rather 
sharj)    angles.       The    protlionLv   is    thinly 
punctured,  with  the  sides   nearly  parallel 
behind,  feebly  angulated  in  the  middle,  and 
from  there  convergent  and  almost  straight. 
The  base  is  very  feebly  emarginated  before 
the  scii-telluhi.     The    latter  is  very   short, 
acutely  pointed,  and  has  only  a  few  small 
punctures   at    the    sides.      The   el)jti'a   are 
rather  strongly  punctate-striate,  two  of  the 
dorsal  intervals  being  smootli  and  feebly 
convex,  the  x-est  irregularly  punctured,  and 
the  apical  margins  more  coarsely  and  closely 
punctured.       The     sides    are    moderately 
siiniated  belilnd  the  shoulders  and  the  apical  angles  bluntly  pro- 
duced.    Tlie  piiijidlam  is   finely   rugose,   and    the    sides    of   the 
metastenmm  and  ahdomen  are  strongly  punctured.     The  form  of

and  colour,  aud  possess  little  in  common  except  a  closely  punc- 
tured upper  surface,  costate  elytra,  short  clypeus  and  very  short 
sternal  process. 

The  male  is  shining  green,  blue-green,  fiery-red,  or  purple  above 
and  beneath.  The  body  is  short,  compact  and  moderately  de- 
pressed. The  clypevs  is  much  shorter  than  it  is  broad,  quadrate, 
finely  rugosely  punctured,  with  the  front  margin  straight,  strongly 
reflexed  and  not  toothed  or  notched,  and  the  forehead  without 
a  distinct  carina.  The  'pronoHnn  is  strongly  punctured  all  over, 
moderately  narrowed  in  front  and  siniiated  at  the  sides  beyond 
the  middle.  The  scutelhim  is  sparingly  punctured.  The  elytra 
are  coarsely  and  closely  punctured  in  ro«s  \\hich  enclose  two 
costa*  upon  the  disc  of  each,  only  the  punctures  towards  the  sides 
and  apices  being  irregular.  The  pygidium  is  rugose.  The  sternal 
process  is  narrow,  but  very  short  and  blunt.  The  metasternum  is 
thinly  punctured  at  the  sides  and  broadly  furrowed  at  the  middle, 
and  the  ahdouten  is  barely  punctured  aud  neither  channelled  nor 
arched  beneath.  The  front  tihiie  are  unarmed,  and  the  middle 
and  hind  tibia'  moderately  fringed. 

The  female  is  black,  or  brownish  black,  scarcely  shining,  elon- 
gate, nearly  parallel-sided,  and  more  convex  than  the  male.  The 
puncturation  is  similar,  but  that  of  the  elytra  shallower  and  less 
distinct.  The  head  is  more  coarsely  rugose,  with  a  posterior 
carina  terminating  abruptly  in  front  but  scarcely  produced.  The 
front  margin  is  a  little  produced  upwards  in  the  middle,  the 
process  generally  ending  in  two  teeth.  The  prothorax  is  almost 
semicircular  in  shape.  All  the  tarsi,  especially  those  of  the  hind 
legs,  are  very  short,  the  front  tibicn  are  broad  and  bidentate,  and 
the  hind  tVme  are  very  scantily  fringed  at  the  inner  edge.

The  body  is  moderately  elongate,  not  much  depressed,  and 
rather  strongly  and  uniformly  punctured  above.  The  head  is 
rugosely  punctured,  with  tlie  clypeus  rather  broader  than  it  is 
long  and  the  front  margin  prominent  in  the  middle.  The 
prothorax  is  coarsely  and  closely  punctured,  with  the  interstices 
extremely  finely  punctulated.  The  scittelhnu  is  punctured,  excepr 
along  the  middle  line,  and  the  elytra  rugosely  punctured,  some  of 
the  punctures  forming  double  rows.  T\w pygidimn  is  transversely 
rugose,  the  ruetasternma  smooth  in  the  middle  and  coarsely 
punctured  at  the  sides,  and  the  ahdomea  finely  punctured.  The

In  the  peculiar  differences  of  form  and  colour  between  the  two 
sexes  this  species  shows  relationship  only  to  H.  vintahilis,  Hope, 
from  which  it  is  quite  easily  distinguished.  It  is  larger  and  has 
less  distinctly  costate  elytra,  besides  which  the  sternal  process, 
although  short,  is  much  less  so  than  in  that  species,  and  the 
clypeus  is  longer  and  quite  differently  shaped  both  in  male  and 
female.

H.  eler/ans  is  distinguishable  from  all  other  Indian  species  of 
the  genus  by  its  extremely  glossy  surface,  as  well  as  by  the  black 
spot  near  the  end  of  each  elytron.  The  latter  varies  greatly  in 
size  but  is  rarely  very  small  and  sometimes  forms  a  large  irregular 
patch.  In  the  great  series  in  M.  Oberthiir's  collection  are 
examples  from  Chota  Nagpur  in  which  the  black  pigmentation  is 
considerably  developed.  The  apical  patch  is  large,  there  is  a  well-

broad,  closely  punctured,  with  the  front  margin  straight  and 
broadly  elevated  in  the  middle,  the  forehead  being  provided  with 
a  semicircular  horizontal  lobe.  The  prothorax  is  rather  short, 
rapidly  narrowed  to  the  front,  and  coarsely  and  uniformly 
punctured.  The  scutellum  is  irregularly  punctured.  The  elytra 
are  strongly  and  coarsely  punctured  in  rows,  the  punctures  annular, 
partly  confluent,  and  leaving  two  smooth  costae  upon  each  elytron  ; 
the  a'pical  aud  posterior  lateral  margins  are  rugose.  T\\e  ivjgkUum

Bright  green,  or  lier}-  red,  the  whole  insect  above  and  below 
uniformly  coloured,  except  the  antennae  and  tarsi,  which  are  black. 

The  form  is  modei'ately  elongated  and  rather  flat.  The  licad  is 
rugosely  punctured,  the  chipexis  being  quadrate  and  shorter  than  it 
is  broad,  with  the  front  margin  straight,  reflexed  and  armed  with 
a  broad  vertical  tooth  in  the  middle.  The  forehead  is  furnislied 
with  a  short  and  broad  horizontal  lobe.  The  prothorax  is  rather 
coarsely  punctured,  the  scutellum  feebly,  and  the  eh/tra  strongly 
and  closely,  most  of  the  punctures  upon  the  last  arranged  in 
regular  rows  which  leave  two  elevated  costa)  upon  the  disc  of  each

with  the  elytra  (except  along  the  suture),  the  femora  and  tibife 
lighter  in  colour  than  the  rest  ot"  the  body. 

The  shape  is  moderately  elongated,  the  female  more  oval  and 
compact  than  the  mule.  The  liead  is  rather  short,  rugoselj 
punctured,  with  a  smooth  median  carina  (which  is  sharply  elevated 
and  free  in  front  in  the  female  only).  The  chjpens  is  rather  broader 
than  it  is  long,  with  the  margins  curvilinear  and  strongly  reflexed 
and  the  front  edge  broadly  elevated  in  the  middle.  The  pro- 
thorax  is  rather  short,  narrox^ed  in  front  in  the  male,  and  approx- 
imately semicircular  in  the  female,  with  the  sides  sinuated  beyond 
the  middle  and  the  disc  rather  strongly  punctured  all  over.  The 
scutellum  bears  a  few  punctures  and  the  elytra  are  rather  coarsely 
punctnred,  with  two  costae  indicated  upon  the  disc  of  each  and  the 
external  margins  rugose  posteriorly.  The  piigidium  is  rugosely 
granular  and  hairy  and  bears  a  broad  shallow  impression  on  each 
side.  The  mctastermim  is  coarsely  punctured  and  clothed  with 
yellow  hair  except  in  the  middle,  and  the  abdomen  is  very  smooth. 
The  sternal  j'rocess  is  not  very  long  and  tapers  to  a  point. 

The  two  sexes  differ  considerably  in  appearance.  The  male  is 
more  elongate,  more  shining,  and  frequently  of  a  brighter  colour 
than  the  female,  and  in  addition  to  the  different  form  of  the  head, 
prothorax  and  front  tibiae,  the  legs  and  the  club  of  the  antenna 
are  more  slender.     The  abdomen  is  not  channelled  beneath.

This  is  a  small  species,  rather  elongate  in  form,  depressed  above 
and  strongly,  almost  rugosely,  punctured.  The  head  is  rather 
parallel-sided,  excavated  and  granulated,  with  the  margins  not 
much  elevated  and  the  anterior  process  bifid,  with  the  points  not 
very  divergent.  The  protliorax  and  eliitra  are  coriaceous  and 
strongly  punctured,  and  there  are  rudimentary  costse  upon  the 
latter.  '  The  sides  of  the  prothorax  are  sinuated  and  completely 
margined,  the  hind  angles  rather  prominent  and  the  base  strongly 
excised  before  the  scutellum,  which  bears  a  few  fine  punctures. 
The  sides  of  the  elytra  are  rather  strongly  sinuated  behind  the 
shoulders.  The  jujgidiuni  is  feebly  rugose,  the  metasternum  punc- 
tured and  clothed  with  long  yellow  hairs,  except  in  the  middle, 
which,  with  the  abdomen,  is  smooth  and  shining.  The  sternal 
process  is  extremely  slender  and  curved. 

6 .  The  posterior  cephalic  process  is  slender  and  acutely 
pointed,  and  the  prothorax  tapers  towards  the  front.  The 
abdomen  is  not  channelled  beneath.

Group  4.   Cj:to\ii/)i:.s. 

This  is  the  largest  and  most  typical  Group  in  the  Subfamily.  The 
species  are  generally  compactly  built  and  most  of  them  are  covered 
on  the  upper  surface  with  a  dull  bloom  and  decorated  with  a  white 
or  yellow  powdery  matter.  The  base  of  the  pronotum  has  its 
sides  inclined,  not  in  a  transverse  line  as  in  the  previous  group, 
and  is  excised  in  front  of  the  scutellum,  the  posterior  angles 
of  the  prothorax  becoming  obtuse  and  sometimes  completely 
obliterated.  The  scutellum  is  generally  blunt  at  its  apex  and 
is  never  very  acute,  as  in  the  remaining  groups  of  Cktoniini  and 
the  CiiEMASi'ociiiLiNA.  The  sexes  are  alike  or  distinguis'r.ed  only 
by  slight  external  differences.

to  them,  I  give  the  following  description  from  the  type  specimen 
kindly  lent  me  by  the  Berlin  Entomological  National  Museum. 

Var.  ceylonensls. 

Black,  with  the  head,  legs  aud  lower  surface  shining  and  the 
upper  surface  and  pygidium  opaque  ;  decorated  with  small  greyish 
spots  upon  the  head,  pronotum  (a  lateral  and  sublateral  line  of 
spots  on  each  side),  scutellum  (a  spot  in  each  angle),  elytra, 
pygidium,  and  the  sides  of  the  metasteruum  and  abdomen.  The 
spots  are  most  closely  aggregated  behind  the  outer  margins  and 
at  the  apices  of  the  elytra,  upon  the  pygidium  aud  the  sides  of  the 
body  beneath. 

The  form  is  as  described  above,  but  it  is  larger;  the  front 
margin  of  the  clypeus  is  straight,  the  sides  of  the  prothorax  are 
angulated  exactly  in  the  middle  and  the  base  is  angularly  emar- 
ginate before  the  scutellum.  There  are  a  few  coarse  punctures 
close  to  the  sides.  The  scatellum  is  rather  long  and  narrow.  The 
elytra  are  coarsely  punctured  in  irregular  rows  and  the  alternate 
intervals  are  elevated.  The  pygidium  is  coarsely  rugose,  the 
middle  of  the  metastermmi  and  abdomen  sparsely  punctured,  and 
the  sides  decorated  with  large  crescent-shaped  impressions.     The

Anthracophora  bufo,  Arrotv*  Arm.  May.  Nat.  Hist.  (7)  xix,  1907, 
p.  353. 

Deep  red-brown,  irregularly  speckled  above  and  below  with 
yellow  markings ;  opaque  and  velvety,  except  at  the  middle  of  th© 
prothorax,  metasternum  and  abdomen  and  a 
stroug  costa  on   the  anterior  half  of   each 
elytron. 

The  form  is  ovate  and  depressed.  The 
clypeus  is  broad,  entire  and  strongly  punc- 
tured. The  jyrotliorax  is  strongly  but  not 
closely  punctured  in  the  middle,  very  coarsely 
and  rugosely  at  the  sides,  with  the  lateral 
margins  distinctly  angulated  at  the  middle, 
and  strongly  sinuated  behind.  ThescuieUum

costa  on  the  basal  half.  The  pygidium  is  rugose,  and  the  meta- 
sternum and  abdomen  are  strongly  punctured  and  shining  in  the 
middle,  but  opaque  and  closely  sculptured  with  crescent- shaped 
impressions  at  the  sides.  The  legs  are  very  short,  opaque,  and 
decorated  like  the  body,  and  there  are  two  very  short  teeth  on 
the  front  tibia.  The  sternal  process  is  short  but  rather  sharply

Black,  with  the  clypeus,  legs  and  lower  surfiice  shining,  the 
upper  surface  and  pygidium  opaque ;  the  elytra  decorated  with 
irregular  brick-red  spots,  scattered  and  inconspicuous  in  front 
and  confluent  behind  the  middle,  where  they  form  a  more  or 
less  extensive  apical  patch.  The  pygidium  and  the  sides  of 
the  abdominal  segments  are  partly  or  entirely  of  the  same 
colour. 


ANTHEACOPEOBA. —  ANATOXA.  113 

The  shape  is  elongate-oval.  The  head  is  very  finely  punctured, 
with  the  chjpeus  short,  almost  straight  in  front  and  with  a  very 
feebly  reflexed  margin.  The  protliorciM  is  very  coarsely  punctured 
at  the  sides  and  has  two  slight  depressions  near  the  front  and  two 
more  near  the  base.  The  sides  are  strongly  angulated  near  the 
middle  and  the  base  deeply  and  narrowly  emarginate  in  the  middle. 
The  scutellum  is  long  and  narrow.  The  ehjtra  are  coarsely  and 
shallowly  punctate-striate  and  the  alternate  intervals  elevated, 
especially  in  the  anterior  part.  The  pygidium  is  microscopically 
rugose,  the  metastenmm  and  abdomen  smooth  in  the  middle  and 
coarsely  rugose  at  the  sides.  The  sternal  pn'ocess  is  very  short, 
broadly  rounded  in  front,  and  bears  a  deep  transverse  groove. 
The //-oni  tibia  is  armed  with  three  sharp  teeth,  the  terminal  one

Black,  with  the  elytra  red  or  chocolate-coloured  and  the  upper 
surface,  except  the  head,  covered  with  a  greyish  or  tawuy  hloom 
and  decorated  with  yellow  markings  as  follows  :  a  border  on  each 
side  of  the  prothorax,  and  two  discoidal  and  two  basal  spots  ;  a 
small  spot  near  the  shoulder  of  each  elytron,  another  near  the 
middle  of  the  inner  margin,  three  small  patches  adjoining  the 
outer  margin,  a  fourth  occupying  the  apical  angle,  and  a  spot  a 
little  in  front  of  the  last.  A  patch  on  each  side  of  the  pygidium 
(sometimes  divided  into  two),  the  mesosternal  epimera,part  of  the 
hind  femora,  and  the  sides  of  the  metasternum  and  abdomen  are 
similarly  decorated. 

The  form  is  short,  oval  and  convex.  The  head  is  granulated 
and  clothed  on  the  vertex  with  long  tawny  hairs.  The  j'l'onottim 
is  rather  strongly  punctured,  with  the  sides  strongly  curved,  the 
front  angles  acute  and  the  hind  angles  almost  obsolete.  The  base 
is  gently  curved  and  very  feebly  emarginate  before  the  scuiellum, 
which  is  short  and  triangular.  The  eh/tra  are  coarsely  punctate- 
striate,  sinuated  behind  the  shoulders  and  sharply  angular,  but 
not  spinose,  at  the  apices.  The  pijr/idiwn  is  finely  punctured  and 
sparingly  clothed  with  yellow  hair.s.  The  metasternum  is  smooth 
in  the  middle  and  thickly  hairy  at  the  sides,  and  the  abdomen  is 
sparingly  punctured  and  setose. 

c5' .  The  abdomen  is  a  little  arched  and  nearly  smooth,  and  the 
hind  tarsi  are  rather  longer  than  those  of  the  female.

The  wide  distribution  of  this  insect  is  very  remarkable.  It 
varies  considerably  in  size  and  in  the  colour  of  the  elytra,  and  in 
its  markings  tends  to  form  local  races,  the  typical  southern  form 
usually  having  the  spots  larger  and  the  thoracic  margin  broader

and  extending  beyond  the  hind  angles.  In  the  northern  form  the 
latter  generally  stops  at  the  angle  and  the  discoidal  spots  are 
absent. 

It  is  exceedingly  abundant  during  the  autumn  rains  in  the 
districts  it  inhabits.  Mr,  T,  R,  D,  Bell  records  that  upon  the 
day  following  a  fall  of  rain  he  has  found  them  swarming  all  over  the 
Khandesh  plateau,  flying  in  thousands  close  to  the  ground,  over 
the  burnt  grass,  and  making  a  humming  noise  like  a  swarm  of  bees, 
which  they  very  much  resemble  on  the  wing.  The  females  burrow 
into  the  ground  and  apparently  deposit  their  eggs  among  the  grass 
roots,  upon  which  no  doubt  the  larvae  feed.  The  beetles  are  also 
sometimes  found  clinging  together  in  clusters,  in  which  the  different 
varieties  occur  together. 


91.  Anatona  alboguttata. 

Anatona  alboguttata,  Burm.,  Hanlb.  Eat.  iii,  1842,  p.  504. 

Black,  with  the  prothorax,  scutellum  and  elytra  opaque,  and 
the  head,  pygidium,  legs  and  lower  surface  shining ;  decorated 
with  the  following  white  markings  : — a  mar- 
ginal line  on  each  side  of  the  pronotum,  a 
narrow  median  line,  not  reaching  the  front 
or  hind  margin  and  interrupted  behind  the 
middle,  and  three  spots  placed  in  a  longi- 
tudinal line  on  each  side ;  the  mesosternal 
epimera  and  a  spot  at  the  apex  of  the 
scutellum  ;  from  six  to  eight  on  each  ely- 
tron and  two  on  each  side  of  the  pygidium 
(sometimes  coalescing).  A  spot  near  the 
extremity  of  each  hind  femur  and  patches  at 
Fig.  26.  the  sides  of   the   sternum,  hind  cox«  and 

Anatona  alboguttata.      abdomen  are  also  white. 

This  species  is  far  larger  than  the  other 
two.  It  is  of  similar  form,  compact  and  convex.  The  head  is 
very  small,  finely  granulated,  clothed  with  long  yellow  hairs  on 
the  forehead,  with  the  clypeus  strongly  rounded  from  side  to  side, 
but  not  carinated.  and  narrow  but  a  little  dilated  in  front.  The 
prothorax  has  the  sides  strongly  rounded,  the  hind  angles 
moderately  well-marked  and  the  base  feebly  excised  in  the  middle. 
The  scutellum  is  short,  with  the  sides  regularly  rounded  and  the 
apex  blunt.  The  elytra  are  smooth,  very  scantily  punctured,  gently 
sinuated  at  the  outer  edges  and  rather  bluntly  angulated  at  the 
apices.  The  injgidmm  is  finely  rugose  and  pubescent,  the  meta- 
sternum  coarsely  rugose  and  pubescent  at  the  sides  and  smooth  in 
the  middle,  and  the  abdomen  almost  smooth.  The  front  tibia  is 
armed  with  three  long  and  sharp  teeth  not  standing  far  apart.

Shining  black  above  and  beneath,  with  the  elytra  sometimes 
reddish  chestnut,  and  thinly  clothed  with  tawny  hairs,  except  upon 
the  scutellum  and  at  the  middle  of  the  metasteruum  and  abdomen, 
the  hairs  being  very  short  and  scanty  upon  the  elytra. 

The  size  and  form  are  the  same  as  those  of  A.  stillata.  The 
head  is  granulated  and  the  proihorax  very  strongly  and  uniformly 
punctured,  with  the  sides  rounded,  the  hind  angles  obsolete,  and 
the  base  broadly  emarginate  in  the  middle.  The  scutellum  is 
smooth  and  marked  with  a  slight  longitudinal  impression  ;  and  the 
elytra  are  marked  with  rows  of  large,  shallow  and  more  or  less 
confluent  pits  ;  the  sides  are  sinuated  and  the  apical  angles 
fairly  well  marked.  The  i>y<jidium  is  rugose,  the  mttasternum 
smooth  in  the  middle  and  punctured  at  the  sides,  and  the  ventral 
segments  have  each  a  median  row  of  punctures  and  are  irregularly 
punctured  at  the  sides.  The  teeth  of  the  front  tibia  are  strong, 
the  1st  and  3rd  sharp  and  directed  obliquely  forward,  and  the  2nd 
broad  and  directed  slightly  backward.

Body  small,  compact  and  convex.  Clypeus  flat,  narrowed  a 
little  to  the  front,  with  the  anterior  augles  forming  reflexed  teeth. 
Pronotum  convex,  narrow  in  front,  with  the  sides  regularly 
curved,  the  hind  augles  completely  obliterated,  and  the  base 
gently  curved  and  hardly  perceptibly  sinuated  before  the  scutellum. 
Scutellum  short,  broad  at  the  base  and  moderately  sharp  at  the 
apex.  Elytra  moderately  sinuated  at  the  side  margins  and  not

The  two  interesting  little  species  for  which  I  have  formed  this 
genus  are  both  characterised  by  markings  composed  of  a  peculiar 
silky  matter  having  a  pearly-blue  lustre  which  in  certain  lights

beneath  are  clothed  with  yellow  setae. 

It  is  a  very  small  insect,  elongate-oval  and  convex  in  shape. 
The  chjpeus  is  granulated,  with  its  front  angles  very  sharp.  The 
pronotum  is  distinctly  punctured  except  in  the  middle  and  the 
basal  margin  is  gently  curved,  with  a  hardly  perceptible  sinuation 
in  the  middle.  The  scutellum  is  short  but  rather  sharp  at  the

irregular  double  rows,  extending  from  the  base  nearly  to  the  apex. 
The  pygidium  is  strigose,  and  the  metasternum  and  abdomen  are 
very  smooth  and  shining  in  the  middle.

with  the  borders,  leaving  only  a  median  cross-shaped  black  mark  ; 
the  mesosternal  epimera  and  parts  of  the  scutellum ;  the  lateral 
parts  of  the  elytra  (continued  round  the  apical  margins  but  some- 
times interrupted),  and  a  median  and  a  subapical  spot  upon  each 
(sometimes  united  to  the  borders).  The  greater  part  of  tlie 
pygidium,  the  sides  of  the  sternum,  a  row  of  minute  spots  on  each 
side  of  the  abdomen,  and  a  large  patch  upon  each  hind  femur  are 
also  of  the  same  colour. 

This  is  a  very  small  species,  elongate-oval  and  very  convex. 
The  head  is  densely  granulated,  with  the  sides  of  the  dypevs 
strongly  rounded,  the  front  margin  refiexed  and  the  front  angles 
rather  produced.  The  irronotam  is  strongly  punctured,  rather 
narrow  in  front,  with  the  posterior  angles  little  indicated  and  the 
base  regulai-ly  curved  and  verj^  gently  emargiuate  in  the  middle. 
The  scutellum  is  short  and  rather  blunt,  and  the  elytra  are  strongly 
punctured  in  rows,  well  sinuated  at  the  sides  and  rather  obtuse 
at  the  apical  angles.  The  ptfjidium  is  smooth,  finely  and  sparsely 
punctured,  the  sides  of  the  metastenium  strongly,  and  those  of 
the  abdomen  slightly,  punctured  and  pubescent.  The  mesostenium 
is  eetose,  little  dilated  before  the  coxae  and  not  produced,  aud  the 
front  tibia  is  armed  with  three  strong  teeth. 

c5' .  The  abdomen  is  broadly  channelled  and  the  hind  tibiae  and

tibiae  truncate  at  the  end,  and  all  the  tarsi  considerably  longer  than 
the  tibiae,  the  middle  ones  about  twice  as  long. 

The  female  is  not  yet  known. 

Although  of  very  distinctive  form,  this  new  genus  is  nearly 
related  to  GJycyphana,  from  which  it  differs  in  having  the  pro-

Cetonia  oatesi,  Ge&tro*  Ann.  Mus.  Genova,  (2)  x,  1891,  p.  848. 

Black,  with  the  pronotum,  scutellum  and  elytra  opaque,  and 
decorated  with  white  or  pale  yellow  markings  as  follows  :— a 
border  at  each  side  of  the  pronotum  and  a  pair  of  minute  spots  at 

the  middle  ;  an  irregular  patch 
beyond  the  middle  of  each  elytron, 
adjoining  the  lateral  margin  and 
sending  a  short  process  towards  the 
inner  margin,  and  an  apical  border, 
slightly  dilated  at  the  suture  ;  three 
irregular  spots  on  each  side  of  the 
pygidium  ;  the  mesosternal  epimera ; 
the  sides  of  the  sternum,  hind  coxae 
and  abdomen,  and  patches  upon  the 
middle  and  hind  femora. 

The  body  is  slightly  depressed, 
not  very  elongate  and  scarcely 
narrowed  behind.  The  eyes  are  very 
prominent,  the  Jiead  rugose,  with 
the  vertex  hairy  and  the  chjpeus 
rather  flat,  long  and  narrow,  the 
sides  rather  straight,  and  the  auterior 
edge  broadly  emarginate  and  scarcely 
reflexed.  The  surface  of  the  pro- 
notum, scutellum  and  elytra  is  very  smooth  and  not  perceptibly 
punctured.  The  pronotum  is  very  narrow  in  front  and  i-atber 
elevated  in  the  middle,  the  sides  are  rather  straight  in  front 
and  strongly,  almost  semicircularly,  rounded  behind,  the  hind 
angles  completely  obliterated  and  the  base  very  feebly  emarginate 
in  the  middle.  The  pygidium  is  finely  rugose,  and  the  metastemum 
and  abdomen  are  very  smooth  in  the  middle  and  thinly  clothed 
with  whitish  hairs  at  the  sides. 

S  .  The  front  tibiae  are  rather  broad,  slightly  sinuated  at  the 
end  externally  but  scarcely  toothed,  the  middle  tibiae  are  very 
short,  and  all  the  tarsi,  especially  those  of  the  front  and  middle 
legs,  are  very  long  and  slender.     The  apical  angles  of  the  elytra 
are  very  strongly  spinose.     The  abdomen  is  arched. 
The  female  is  unknown.

Opaque  velvety-black  above,  with  the  head,  legs  and  lower 
surface  shining  and  very  minutely  and  thinly  setose ;  the  pronotum 
completely  encircled  with  a  deep  red  marginal  band,  the  pygidium 
and  last  ventral  segment  red  and  each  elytron  ornamented  with  a 
glistening  silvery  or  golden  triangular  patch  placed  just  behind 
the  middle,  with  its  base  reaching  the  outer  margin.  The  outer 
edges  of  the  hind  coxae  are  of  the  same  colour. 

The  species  is  long  and  narrow  in  shape.  The  head  is  rugosely 
punctured,  with  the  chjpeus  not  long,  a  little  narrowed  towards 
the  front  and  deeply  notched.  The  protliorax  is  strongly  trans- 
verse, moderately  and  evenly  punctured,  rather  narrow  in  front, 
where  it  is  very  sloping  on  each  side  of  the  middle,  with  the  sides 
strongly  and  evenly  curved,  the  hind  angles  obsolete  and  the  base 
very  slightly  emarginate  in  the  middle.  The  seutellum  is  long  and 
narrow.  The  elytra  are  deeply  punctate-striate,  with  the  sides 
strongly  sinuated  close  to  the  sliouiders  and  the  sutural  angles  not 
sharp.  The  ijyfjidium  is  rather  flat,  opaque,  and  finely  striolated 
transversely,  the  metastenium  is  smooth  in  the  middle  and  coarsely 
striolated  at  the  sides,  and  the  abdomen  is  coarsely  and  not  closely 
punctured.     The  front  tibia  is  armed  with  three  sharp  teeth.

6r.  horsfieldi  has  been  recorded  as  frequenting  the  flowers  of 
Hibiscus. 

This  species  seems  to  occur  throughout  a  large  part  of  the 
Indian  area  and,  as  might  be  expected,  is  highly  variable,  the 
varieties  being  to  some  extent  localised.  The  typical  form  (from 
the  Himalayas)  is  small  and  narro\\-,  with  rather  small  triangular 
golden  elytral  patches.  The  Ceylon  form  is  generally  rather 
larger  and  broader,  with  the  golden  patches  rather  large. 
A  similar  form  occurs  at  Chota  Nagpur. 

A  striking  variety,  of  which  the  exact  locality  is  not  known,  has 
the  golden  area  extending  almost  to  the  base  and  apex  of  the  elytra. 
This  may  be  called  var.  auridenta. 

In  the  var.  biargentata  the  red  markings  have  disappeared.  Its 
precise  habitat  is  also  uncertain.

blood-red ;  the  elytra  traversed  just  beyond  the  middle  by  a 
glistening  golden  band,  very  narrowly  interrupted  at  the  suture, 
the  front  edge  forming  a  nearly  straight  line,  the  hinder  edge 
strongly  concave. 

The  body  is  depressed  in  shape  and  moderately  elongate.  The 
head  is  broad,  closely  punctured,  and  deeply  notched  at  the  front 
margin.  The  pronotum  is  a  little  wider  than  it  is  long,  with  the 
lateral  and  posterior  margins  continuously  curved,  the  hind  angles 
obsolete  and  the  base  very  feebly  siuuated  in  front  of  the  scutellum. 
The  scutellum  is  rather  pointed.  The  ehjtra  are  punctate-striate, 
strongly  sinuated  behind  the  shoulders  and  not  spinose  at  the 
apical  angles.  The  pii(jklium  is  minutely  striolated  transversely,

with  a  deep  red  band,  more  or  less  interrupted  in  the  middle  of 
the  base.  In  the  $  the  pygidium  has  a  large  patch  of  the  same 
colour  ou  each  side  and  each  elytron  has  a  bright  orange-yellow 
patch  placed  just  behind  the  middle  of  the  outer  margin.  In  the 
S  the  patches  on  the  pygidium  are  bright  yellow  and  there  are 
two  orange  spots  placed  transversely  on  each  elytron,  the  inner 
spot  a  httle  behind  the  outer  one.  The  sides  of  the  sternum  and 
abdomen  are  with  or  without  yellow  patches. 

The  body  is  long,  narrow  and  very  depressed.  The  head  is 
finely  and  closely  punctured,  with  the  clypeus  broad  and  bilobed. 
The  pronotum  is  strongly  punctured,  very  transverse,  much 
narrowed  in  front,  where  it  is  sharply  elevated  in  the  middle,  with 
the  hind  angles  entirely  obliterated  and  the  base  gently  sinuated.

All  the  Burmese  specimens  I  have  seen  are  females  and  the 
description  of  the  male  is  therefore  taken  from  the  specimens 
collected  outside  our  boundaries.  All  the  Burmese  examples 
differ  from  other  females  in  the  larger  size  of  the  yellow  elytral 
patch,  and  there  may  therefore  be  a  corresponding  difference  in 
males  from  the  same  region. 

The  male  of  this  species  has  been  generally  known  as 
O.  torquata,  F.,  but  incorrectly.

eight  minute  spots  on  each  elytron.  The  sides  of  the  pygidium, 
sternum  and  abdomen  are  also  pale  yellow. 

This  is  a  very  small,  elongate  and  depressed  species.  The  head 
is  densely  punctured  and  not  very  strongly  emarginate  in  front. 
The  pronotum  is  strongly  punctured  all  over,  narrower  than  the 
elytra  but  distinctly  transverse,  with  all  the  angles  obsolete,  the 
sides  strongly  curved,  and  the  base  gently  sinuated.  The  scutellum 
is  long,  with  curvilinear  sides,  and  very  blunt  at  the  apex.  The 
elytra  are  coarsely  punctate-striate,  with  the  sides  strongly  sinuated 
behind  the  shoulders,  and  the  apical  augles  acute.  The  pygidium 
is  concentrically  striated,  and  the  sternum  and  abdomen  are  clothed, 
like  the  legs,  with  short  yellow  sette,  except  along  the  middle  line, 
where  they  are  smooth  and  shining.

Deep  olivaceous-green ;  the  elytra  with  a  yellow  oblique  stripe 
at  the  middle  of  each,  extending  from  the  front  margin  to  a  little 
before  the  hind  margin,  two  short  and  fine  transverse  white  lines 
at  the  posterior  part  of  the  outer  margin,  and  a  minute  white  spot 
in  the  apical  angle  ;  the  prothorax  with  white  patches  or  lines 
upon  the  front  angles  beneath.  The  mesosterual  epimera  and  the 
sides  of  the  metasternum,  hind  coxae  and  abdomen  are  also  white. 
Tbe  upper  surface  is  opaque  and  the  head,  legs  and  lower  surface  are

area  in  front  of  the  scutellum.  There  are  also  white  or  pale  yellow- 
markings  consisting  of  a  pair  of  minute  spots  at  the  middle  of  the 
pronotum  and  a  second  anterior  pair  (one  or  both  pairs  frequently 
absent),  a  transverse  patch  beyond  the  middle  of  each  elytron, 
adjoining  the  outer  margin,  and  three  minute  spots  anterior  and 
three  posterior  to  this  patch  (some  of  them  frequently  absent).  In 
the  (S  the  sides  of  the  pygidium  and  those  of  the  sternum  and 
abdomen  are  broadly  bordered  with  the  same  colour.  In  the  $ 
the  pygidium  is  black  and  shining,  and  the  sides  of  the  abdomen 
are  only  partially  decorated  with  white. 

The  body  is  depressed  and  moderately  elongate,  and  the  upper 
surface  is  studded  with  extremely  minute  setae.  The  head  is 
finely  and  closely  punctured,  and  the  front  margin  moderately 
deeply  notched  in  the  middle.  The  prothorax  is  very  short  and 
transverse,  finely  and  fairly  closely  punctured  above,  with  the 
hind  angles  rounded  off  and  the  base  sinuated.  The  scutellum  is 
short  and  very  blunt.  The  elytra  are  strongly  jjunctate-striate, 
with  the  apical  part  rugose,  the  lateral  margins  strongly  sinuated 
behind  the  shoulders,  the  apical  margins  finely  serrated  and  the 
apical  angles  spinose.  The  pygidmm  is  transversely  strigose,  the 
metasternum  and  abdomen  are  sparingly  punctured  in  the  middle 
and  rugosely  at  the  sides,  and  the  sternal  process  is  very  short  and 
broad.     The  uppermost  tooth  of  the  front  tibia  is  rather  feeble.

Dark  green,  olive,  or  (in  the  $  )  black,  opaque  above,  with  the 
head,  legs  and  lower  surface  shining  castaueous  or  blackish ; 
decorated  with  whitish  markings,  consisting  of  a  longitudinal  line 
on  each  side  of  the  forehead,  a  narrow  lateral  line  on  each  side  of 
the  pronotum  and  four  small  discoidal  spots  (a  pair  near  the  middle 
placed  rather  wide  apart  and  an  anterior  pair  placed  nearer 
together),  a  minute  spot  at  each  anterior  angle  of  the  scutellum, 
and  about  eight  irregular  spots  upon  each  elytron.  There  are

encircling  line,  and  a  series  at  the  sides  of  the  sternum,  bind 
coxae,  and  abdomen,  the  latter  very  small  in  the  $  ,  but  forming 
a  continuous  broad  band  in  the  J  . 

The  shape  is  moderately  elongate  and  depressed.  The  head  is 
closely  and  evenly  punctured,  except  upon  the  vertex,  and  rather

each,  broad  at  the  outer  margin  and  pointed  at  its  inner  extremitv. 

The  form  is  depressed,  broad  at  the  shoulders,  with  the 
head  small,  and  the  elytra  straight  at  the  sides  and  strongly 
narrowing  towards  the  extremity.  The  Jiead  is  strongly  punc-

upon  the  pjgidium  are  deep  blood-red,  and  there  are  markings  of 
white  or  pale  yellow,  subject  to  great  reduction,  but  consisting 
typically  of  two  spots  on  the  vertex  of  the  head,  a  circle  of  from 
eight  to  twelve  upon  the  pronotum,  two  or  thi'ee  in  each  posterior 
angle,  a  longitudinal  median  line  continued  upon  the  scutellum,  a 
lateral  patch  beyond  the  middle  of  each  elytron,  with  a  minute  spot 
close  to  its  inner  edge,  three  spots  in  a  triangle  at  the  apex 
of  each  and  an  irregular  swarm  of  minute  spots  extending  to  the 
shoulder.  There  are  also  two  or  four  pale  spots  placed  trans- 
versely upon  the  pygidium  and  two  rows  on  each  side  of  the  body 
beneath. 

The  body  is  depressed,  rather  elongate,  and  only  slightly  nar- 
rowed behind.  The  clypeus  is  strongly  punctured  and  rather 
deeply  notched  in  front.  The  pronotum  is  short,  much  narrowed 
in  front,  broad  at  the  base  and  deeply  and  narrowly  emarginate 
before  the  scutellum.  The  elytra  are  punctate-striate,  deeply 
sinuated  behind  the  shoulders  and  spinose  at  the  apical  angles. 
The  pycjidium  is  a  little  punctured,  the  metasiemum  rugose,  and 
the  abdomen  almost  smooth.  The  sternal  process  is  rounded  and 
prominent  and  directed  obliquely  forward.  The  front  tibia  is 
armed  with  three  sharp  teeth.

CETONIA.  133 

The  body  is  depressed,  broader  than  the  other  species  of  this 
genus,  and  not  perceptibly  narrowed  towards  the  extremity.  The 
surface,  except  in  worn  specimens,  is  clothed  above  and  below 
with  yellow  hairs  or  setse,  short   upon  the   upper   surface   and 

absent  from  the  middle  of 
the  pronotum,  metasternum 
and  abdomen.  The  head  is 
strongly  punctured  and  deeply 
notched  at  the  front  margin. 
The  pronotum  is  very  coarsely 
punctured  and  its  sides  gently 
curved.  The  scutellum  is  long 
and  unpunctured.  The  elytra 
have  each  two  well-marked 
costae  ;  they  are  strongly 
punctured  between  and  out-

The  body  is  rather  narrow  and  distinctly  tapers  behind.  The 
clypeus  is  strongly  and  closely  punctured,  slightly  narrowed  in 
front  and  moderately  notched  at  the  apex.  The  protlioraoo  is  dis- 
tinctly, but  not  closely,  punctured  on  the  disc  and  more  rugosely 
at  the  sides,  which  are  gently  curved,  without  a  distinct  angu- 
lation. The  scutellum  is  unpunctured  and  not  very  long.  The 
elytra  are  rather  strongly  punctured,  with  the  apical  part  rugose 
and  with  two  distinct  costse  on  the  disc  of  each.  The  lateral 
margins  are  strongly  sinuated  and  the  apical  angles  shghtly

evenly  punctured,  with  the  sides  gently  bisinuated  and  the  hind 
angles  moderately  sharp.  The  scutelliim  is  smooth,  and  the  elytra 
are  coarsely  wrinkled  transversely  and  irregularly  pitted  with  very 
large  annular  punctures  ;  there  is  a  broad  depression  at  the  inner 
posterior  half  of  each  elytron.  The  propyciidium  and  pygidium 
are  finely  transversely  strigose,  the  metasternum  coarsely  punc-

emarginate.  Prothorax  with  the  base  inclined  on  each  side  and 
abruptly  emarginate  in  the  middle.  Scutellum  moderately  long, 
with  the  apex  blunt  and  rounded.  Elytra  sinuated  laterally  behind 
the  shoulders,  with  the  apical  angles  acute,  frequently  spinose. 
Front  tibia  ax*med  with  two  or  three  short  teeth,  except  in  the  d" 
of  P.  albogiUtata.  Hind  tibia  truncated  at  the  end.  Sternal 
process  short  and  flattened,  widened  in  front  of  the  middle  coxse  and 
straight  or  broadly  rounded  in  front,  except  in  P.  confusa. 

Except  in  P.  albogntlata,  the  sexes  are  closely  similar  and  the 
abdomen  is  rai-ely  excavated  or  arched  in  the  male.  The  spurs 
of  the  hind  tibiae,  however,  are  always  shorter  and  sharper  in  that 
sex,  and  the  last  ventral  segment  is  smoother.  In  some  of  the 
species  the  anterior  edge  of  the  clypeus  bears  two  recurved  teeth 
which  are  feebler  or  quite  absent  in  the  female. 

This  is  a  very  large  and  polymorphic  genus,  which  may  be 
regarded  as  the  central  mass  of  the  subfamily  froui  which  other 
genera  diverge  iu  all  directions.  Such  a  niass  is  found  in  nearly 
every  large  group  and  the  difficulty  of  fixing  its  limits  is  invariably 
very  great.  Tentative  efforts  to  divide  it  into  smaller  genera  are 
often  made,  but  are  generally  doomed  to  failure  as  the  number  of 
known  species  increases.  In  the  present  case  numerous  so-called 
genera  have  been  formed  for  single  species,  or  upon  the  strength 
of  features  peculiar  to  one  sex,  and  I  have  found  it  necessary  to 
abandon  several  of  these  which  have  failed  to  stand  the  test  of 
tabulation. 

In  the  key  which  follows,  one  species,  P.  alboguttata,  Vigors,  is 
omitted,  because  it  is  difficult  to  find  any  features,  except  colour 
and  marking,  which  are  common  to  the  two  sexes  and  which 
would  not  be  liable  to  mislead  if  used  for  the  purpose  of  tabula- 
tion. Such  marked  dimorphism  is  entirely  abnormal  iu  the 
present  genus,  and  it  would  be  desirable  to  form  a  new  genus  or 
subgenus  for  this  species  but  that  the  female  presents  no  really 
distinctive  characters,  and  indeed  is  very  similar  to  P.  lonrji- 
pennis,  etc.

lu  the  Munich  Catalogue  P.  mixta,  Y,  is  quoted  as  an  Indian 
species.  I  have  examined  the  type  of  this  from  the  Copenhagen 
Museum  and  find  it  to  be  a  species  only  known  to  occur  in 
Sumatra.  The  same  specimen  was  the  original  of  Weber's 
description,  published  earlier  than  that  of  Fabricius,  and  quoted 
by  the  latter.  The  Munich  Catalogue  therefore  also  errs  in 
treating  the  species  as  synonymous  with  our  P.  fti.sca  (mandarina, 
Weber).

Olivaceous-green,  brassy  or  coppery,  with  the  pygidium,  lower 
surface  and  legs  lurid  green,  red  or  purple,  and  sometimes  with 
the  head  and  the  extreme  edges  of  the  prothorax  and  elyti-a  tinged 
with  the  same  colour.  The  prothorax  and  scutellum  are  frequently 
rosy  or  fiery  red.  The  upper  surface  is  smooth,  but  not  highly 
glazed,  and  the  lower  surface  is  very  sparsely  clothed  with 
yellowish  hairs. 

The  body  is  moderately  stout  and  not  much  depressed  above. 
The  head  is  strongly  and  closely  punctured  and  the  clypeus 
quadrate,  with  the  front  margin  strongly  reflexed  and  very  lightly 
excised  in  the  middle.  The  2^^^onotum  is  finely  (sometimes  very 
finely)  and  rather  uniformly  punctured,  rather  convex,  strongly 
margined  and  very  gently  curved  at  the  sides,  and  narrowly  and 
deeply  emarginate  in  the  middle  of  the  base.  The  scutellum  is 
quite  smooth  and  moderately  long  and  pointed.  The  elytra  have 
each  a  well-marked  broad  depression  adjoining  the  suture  upon 
the  posterior  half,  in  which  there  are  fines  of  horseshoe-shaped 
impressions.  In  front  of  the  depressions  they  are  only  very 
minutely  punctured,  and  at  the  sides  more  strongly  and  closely. 
The  lateral  margins  are  gently  sinuated  behind  the  shoulders,  and 
the  apical  angles  sharp  but  not  spinose.  T\iQ pygid'nnn  is  finely 
transversely  corrugated,  the  metasternum  less  finely  corrugated  at 
the  sides,  and  the  abdomen  almost  smooth.  The  sternal  process 
is  flat  and  transversely  oval  in  shape.  The  front  tibia  is  armed 
with  three  slight  sharp  teeth,  and  the  Jiind  tibia  has  a  fringe  of 
yellow  hairs  at  the  inner  edge.

140  CBTONIIN.I. 

Various  accounts  have  been  published  by  Continental  entomo- 
logists of  the  habits  o£  this  very  common  and  widely-distributed 
insect,  which  in  Europe  is  frequently  confused  with  the  common 
-Rose-beetle  (Cetonia  aurata,  L.),  which  it  considerably  resembles. 
In  its  adult  form  it  feeds  voraciously  upon  the  juices  of  ripe  fruit 
and  other  sweet  liquids,  and  M.  Pabre  has  watched  them  absorbing 
for  a  fortnight  without  intermission  the  juice  of  fruit  supplied  to 
them.  This  is  during  the  summer  and  autumn  following  their 
emergence.  The  succeeding  winter  is  passed  (in  Europe)  iu 
quiescence  below  the  surface  of  the  ground,  and  ovipositiou  does 
not  take  place  until  the  following  year.  The  female  deposits  her 
eggs  in  accumulations  of  decaying  leaves  or  other  vegetable  matter, 
or  by  preference  in  nests  of  the  large  AVood-Ants  (Formica  rufa 
and  praUasis),  burrowing  a  short  distance  below  the  surface  for 
that  purpose.  The  larvse  spend  two  or  three  years  feeding  upon 
the  vegetable  substance  which  they  find  at  hand.  Mr.  Weaver  is 
repoi'ted,  in  the  Proceedings  of  tlie  Entomological  Society,  1851, 
p.  105,  to  have  stated  that  he  saw  large  quantities  of  the  ants' 
eggs  devoured  by  the  larvje,  but  it  is  probable  that  this  was  only 
due  to  their  being  removed  from  the  nest  and  kept  without  other 
suitable  food.  Larvae  of  various  ages  are  commonly  found  together, 
the  youngest  according  to  Wasmaun  (Deutsche  Eutomologische 
Zeitschrift,  1887,  xxxi,  p.  45)  generally  living  in  the  deeper  parts 
of  the  nest  and  those  more  advanced  nearer  the  surface,  where  the 
cocoon  is  also  found.  The  latter  is  similar  to  a  pigeon's  egg  in 
size  and  shape,  and  formed  by  the  agglutination  of  fragments  of 
the  food-material,  the  interior  being  coated  with  matter  apparently 
exuded  from  the  intestine,  producing  a  perfectly  smooth  and 
shining  surface.  The  construction  of  the  cocoon  appears  to 
be  the  chief  function  of  the  legs,  progression  being  accomplished 
by  the  movements  of  the  dorsal  segments.  After  a  period  of  one, 
two,  or  three  months  in  the  pupal  stage  the  beetle  ruptures  the 
cocoon  and  makes  its  way  above  ground.  The  ants  seem  to 
resent  the  intrusion  of  the  beetle  into  their  nest,  but  owing  to 
its  hard  exterior  can  scarcely  injure,  although  they  may  hinder,  it. 
The  larvje,  however,  are  left  undisturbed  unless  they  give  some 
special  offence,  and  appear  also  to  be  to  some  extent  protected  by 
the  toughness  of  their  skin  and  tlie  stiff  bristles  with  which  it  is 
studded. 

This  larva  is  preyed  upon  by  the  parasitic  wasp,  ScoJia  hifasciata^ 
the  female  of  which  seeks  it  out  and,  having  paralysed  it  by 
stinging  it  in  the  ventral  ganglion-mass,  places  an  egg  upon  it. 
The  issuing  grub  speedily  devours  the  immobile  victim,  and  having 
reduced  it  to  an  empty  skin,  forms  its  cocoon  beside  it. 

The  life-history  of  many  other  species  of  Cetonun.!:  is 
probably  similar  in  the  main  to  that  of  Proiotia  cuprea.

Entirely  deep  golden-green  or  blue-green,  with  the  tarsi  gene- 
rally deep  blue ;  very  smooth  and  shining  and  without  markings 
or  clothing,  except  some  pale  yellow  liairs  upon  the  legs  and  a 
few  very  minute  setse  upon  the  sides  of  the  metasternum. 

It  is  a  broad,  robust  and  moderately  convex  species.  The  Jiead 
is  relatively  small,  scantily  punctured,  with  the  clypeus  rather 
quadrate,  the  front  margin  strongly  reflexed  and  very  feebly 
notched.  The  prothorax  is  strongly  punctured  at  the  sides  and 
scantily  or  not  at  all  in  the  middle  :  it  is  narrow  in  front  and 
strongly  and  rapidly  dilated  towards  the  base,  the  sides  being  little 
curved  and  the  hind  angles  moderately  distinct.  The  basal 
margin  is  not  strongly  excised  before  the  saUellum,  and  the  latter 
is  rather  short  and  triangular,  without  punctures  except  at  the 
base.  The  elytra  are  minutely  and  scantily  punctured  in  rows, 
with  rather  stronger  scattered  punctures  near  the  apex.  The 
pygidium  is  decorated  with  transverse  striations,  the  sides  of  the 
metasternum  are  very  coarsely  strigose,  and  the  abdomen  is  almost 
smooth  beneath.  The  sternal  process  is  short  and  broad,  but 
slightly  prominent,  the  front  tibia  has  three  very  short  teeth  and 
the  hind  tibia  has  a  fringe  of  short  yellow  hairs  and  is  rather 
digitate  at  the  end. 

c? .  The  apical  angles  of  the  elytra  are  sharply  produced  and 
the  pygidium  is  lightly  strigose.

Shining  blue-black  with  minute  white  markings,  variable  in 
number  but  usually  consisting  principally  of  a  median  anterior 
spot,  three  transverse  marks  near  the  outer  margin,  and  three 
near  the  inner  margin  of  each  elytron  (the  latter  upon  the 
posterior  half),  a  minute  spot  on  each  side  of  the  pygidium,  and 
a  row  on  each  side  of  the  sternum  and  abdomen. 

The  body  is  stout  and  rather  convex.  The  head  is  strongly 
and  rather  evenly  punctured,  with  the  clypeus  rather  long,  reflexe'd 
and  feebly  bilobed  in  front.  The  prothorax  is  very  finely  punc- 
tured on  the  disc  and  more  strongly  at  the  sides,  with  the  hind 
angles  rounded  and  the  base  strongly  emarginate  in  the  middle. 
The  scuteUian  is  not  long  and  is  unpunctured  except  in  the 
anterior  angles.  The  elytra  are  closely  set  with  large  crescentic 
punctures  except  in  the  region  of  the  scutellum,  where  the  punc- 
tures are  fine  and  sparse.  The  apical  angles  are  right  angles  and 
not  produced.  The  pygidium  and  propygidium  are  finely  rugose, 
and  the  latter  is  sharply  angular  in  the  middle  of  the  posterior 
margin.  The  sides  of  the  metasternum  are  coarsely  rugose  and 
thinly  clothed  with  short  yellow  hairs,  and  the  abdomen  is  almost 
smooth.  The  sternal  process  is  transverse  and  feebly  produced. 
The  front  tibia  is  armed  with  three  acute  teeth.

Copper-coloured,  with  the  lo\\er  surface  and  legs  fiery  red  and 
the  upper  surface  opaque  ;  decorated  m  ith  white  markings  con- 
sisting of  six  or  eight  minute  spots  on 
each  side  of  the  pronotuni,  a  small  ir- 
regular patch  at  the  outer  margin  of 
each  elytron  considerably  beyond  the 
middle,  and  minute  spots  between  these 
and  at  the  sides.  There  are  also,  a 
small  spot  on  each  side  of  the  pygi- 
dium,  two  or  three  on  each  side  of  the 
sternum,  and  two  rows  ou  each  side  of 
the  abdomen. 

It  is  an  elongate,  depressed  species, 
tapering  gently  from  shoulders  to  apex. 
The  Jtead  is  sparingly  punctured,  but 
more  closely  at  the  sides  of  the  clypeus, 
the  front  margin  of  which  is  very  feebly 
excised  in  the  middle.  The  pronotum 
is  also  sparingly  punctured,  except  at 
the  sides,  the  lateral  margins  are  feebly 
angulated  behind  the  middle,  the  posterior  angles  moderately 
prominent,  and  the  base  narrowly  emarginate  in  the  middle. 
The  scuiellum  is  rather  elongate.  The  eh/tra  are  long,  moderately 
punctured,  and  have  a  broad  depression  upon  the  posterior  half 
near  the  sutvu-e.  The  sides  are  strongly  sinuated  and  the  apical 
auHes  not  produced.  The  pyciidium  is  rugose  and  clothed  with 
short  erect  setse.  The  mesostemal  j^^'ocess  is  short  and  broad,  the 
middle  of  the  metasiernum  and  abdomen  smooth,  the  sides  of  the 
former  rugose,  those  of  the  latter  coarsely  punctured  and  both 
thinly  clothed  with  short  hairs.  The  front  //ia?  are  sharply  tri- 
dentate  and  the  hind  tibia/  closely  fringed. 

I  have  seen  only  the  female,  in  whicii  the  last  two  ventral

its  front  margin  slightly  reflexed  and  scarcely  notched.  The 
pronotum  is  closely  punctured,  the  scutellum  rather  narrow  and 
rounded  at  the  apex,  and  the  elytra  bear  strong  annular  punctures, 
except  in  the  inner  anterior  part,  with  a  well-marked  longitudinal 
costa  posteriorly.  The  outer  margins  are  very  deeply  sinuated 
behind  the  shoulders,  aud  the  apical  angles  sharp  but  not  spinose. 
^he  pygidium  is  closely  strigose  transversely,  and  the  sides  of  the 
metasternum  and  abdomen  are  coarsely  rugose.  The  sternal  process 
is  flat,  broad  and  short.  Vae  front  tibia  is  armed  with  three  sharp

132.  Protastia  bidentipes. 

Protfetia  bideutipes,  Arroiv,*  Ann.  Nat.  Hist.  1007,  (7)  xix,  p.  351. 

Sooty-black  or  piceous  black,  with  the  head,  legs  and  underside 
shining,  decorated  with  yellow  spots  distributed  as  follows  : — a 
pair  upon  the  vertex  of  the  head,  a  pair  at  the  middle  and  three  at 
each  lateral  margin  of  the  pronotum,  the  two  posterior  ones  some- 
times uniting,  three  placed  in  an  oblique  Hne  upon  the  anterior 
half  of  each  elytron,  two  adjoining  the  suture  posteriorly  and  four 
adjoining  the  lateral  margin,  and  a  large  patch  at  each  side  of  the 
pygidium.  There  are  also  patches  upon  the  mesosternal  epimera, 
and  the  sides  of  the  sternum  and  abdomen. 

The  head  is  thickly  punctured,  with  the  dypeiis  long  and  deeply 
notched  in  front.  il\\Q  protliomx  is  very  transverse,  distinctly  but 
not  densely  punctured  all  over,  with  the  sides  strongly  angulated 
in  the  middle  and  nearly  parallel  from  there  to  the  base,  which  is 
strongly  emarginate  before  the  scutellum.  The  smtellumhvoXhev 
narrow.  The  ehitra  are  parallel-sided,  punctate-striate,  with  the 
sutural  angles  rather  spinose.  The  mesosternal  process  is  moderately 
prominent,  nearly  circular  and  not  much  dilated  at  the  end.  The 
metasternum  is  rugose  at  the  sides,  and  the  abdomen  sparsely 
punctured.  The  front  tihice  are  bidentate  in  both  sexes.  The 
pygidium  is  pubescent  in  two  female  specimens  in  the  British 
Museum  collection,  but  in  a  male  in  the  Indian  Museum,  labelled 
(perhaps  wrongly)  "  Eangoon,"  the  setae  are  scarcely  visible.  The 
yellow  markings  in  that  specimen  are  also  of  a  deeper  colour.

The  type  of  P.fusca  cannot  be  identified  with  absolute  certainty. 
Prof.  Kolbe,  of  the  Berlin  Museum,  informs  me  that  a  specimen, 
perhaps  the  type,  in  that  collection  belongs  to  this  species,  whose 
identity  I  think  may  fairly  be  accepted  from  Herbst's  figure,  and 
its  better  original  in  Voet's  Catalogue.  The  type  of  P.  mandarina, 
Weber,  which  should  be  in  the  Copenhagen  Museum,  is  lost,  but 
a  specimen  f i*om  AVestermann's  collection  preserved  there  as  repre- 
senting the  species  belongs  to  P.  acuminata,  E.,  and  Weber's 
description  appears  to  me  to  have  been  drawn  up  from  that  species 
and  the  present  one  jointly. 

This  is  one  of  the  most  widely-distributed  of  all  the  Cetoniin^. 
Mr.  H.  ]Sr.  Ridley,  of  the  Royal  Botanic  Gardens,  Singapore,  tells 
me  that  its  larvae  are  very  injurious  to  Cannas  and  other  cultivated 
plants,  upon  whose  roots  they  feed.  In  Queensland  the  beetles 
have  been  found  to  attack  the  nests  of  the  stingless  bee,  Trigona, 
no  doubt  for  the  sake  of  the  stored  honey.

posterior  part  of  the  pronotuin,  but  forms  a  more  or  less  indefinite 
arcuate  transverse  band  behind  the  middle  of  the  elytra.  The 
sides  of  the  pygidium,  metasternum  and  abdomen  are  generally 
adorned  with  patches  of  the  same  colour. 

The  body  is  moderately  elongate  and  depressed.  The  head  is 
densely  punctured  and  has  a  slight  posterior  longitudinal  carina, 
the  front  margin  of  the  dypeus  being  reflexed  and  entire.  The 
pronohim  is  coarsely  and  thickly  punctured,  with  a  smooth  middle 
Hue  and  two  densely  punctured  impressions  on  each  side  of  it,  the 
posterior  pair  near  the  basal  margin.  The  latter  is  deeply,  but  not 
broadly,  emarginate  in  the  middle,  and  the  lateral  margins  are 
sinuated.  The  scuteUum  is  very  blunt  and  only  punctured  in  the 
anterior  angles.  The  elytra  are  distinctly  and  irregularly  punc- 
tured and  each  has  a  strongly  marked  costa  upon  its  posterior  half. 
The  sutural  margins  are  strongly  raised  and  the  apical  angles 
sharply  produced.  T\\q  'propygidium  is  pointed  and  ihe  pyrjidhim 
finely  rugose.  The  metasternum  is  coarsely  rugose  at  the  sides  and 
the  ahdomen  almost  smooth.  The  sternal  process  is  very  short  and 
broad.  The  front  tibia  is  armed  with  three  very  short  but  sharp 
teeth  and  the  hind  tibia  has  a  thin  yellow  fringe. 

(S  .  The  abdomen,  including  the  last  segment,  is  sparsely  punc- 
tured beneath,  the  spurs  of  the  hind  tibiae  are  short  and  sharp  and 
the  teeth  of  the  front  tibia  very  feeble. 

$  .  The  last  ventral  segment  is  very  thickly  punctured  and  the

The  ehjtra  are  coarsely  and  irregularly  punctured  all  over,  with  a 
well-marked  costa  upon  each.  The  pygidium  and  the  sides  of  the 
metasternum  are  rugose  and  the  abdomen  is  almost  smooth.  The 
mesosternal  'process  is  very  short,  broad  and  densely  setose,  and 
the  front  tibia  has  two  acute  teeth  and  a  very  minute  upper  one.

142.  ProtaBtia  cariana. 

Cetonia  cariana,  Gestro,*  Ann.  Mus.  Genova,  (2)  i,  1891,  p.  850. 

Bronzy,  with  the  legs  and  lower  surface  coppery-red ;  the  pro- 
thorax,  scutellum,  elytra  and  pygidium  clothed  with  a  brown,  or 
olivaceous,  velvety  bloom  ;  the  prothorax  decorated,  except  along 
the  middle  line,  with  irregularly  scattered  yellowish  spots,  and  the 
elytra  with  a  fine  tracery  which  is  less  diffused  than  in  P.  neghcta, 
tending  to  segregate  in  masses  adjoining  the  inner  and  outer 
margins.  The  pygidium  is  speckled  on  each  side  of  the  middle 
line,  and  in  the  male  the  ventral  segments  are  also  speckled 
broadly  on  each  side. 

The  form  is  convex  and  compact.  The  clypeus  is  rather  finely 
and  evenly  punctured,  with  the  front  margin  feebly  reflexed  and 
scarcely  perceptibly  notched.  The  pronotum  is  distinctly  and 
evenly  punctured,  except  along  the  middle  line,  it  is  narrow  in 
front,  with  the  sides  feebly  augulated  in  the  middle  and  the  base 
deeply  emarginate  before  the  scutellum.  The  scutellum  is  long, 
narrow  and  unpunctured.  The  elytra  are  rather  finely  and 
sparingly  punctured,  with  the  apical  angles  not  sharp.  The 
pygidium  is  transversely  striolated  but  not  rugose,  and  the  meta- 
sternum  smooth  in  the  middle,  but  coarsely  striolated  and  hairy  at 
the  sides.  The  sternal  process  is  short  and  broad.  The  legs  are 
stout,  the  front  tibia  armed  with  three  very  feeble  teeth,  and  the 
middle  and  hind  tihice  fringed  with  long  yellowish  hairs. 

(S .  In  addition  to  the  markings  upon  the  abdomen,  mentioned 
above,  this  sex  is  distinguishable  by  the  abdomen  being  feebly 
punctured,  the  hind  tarsi  longer,  and  the  spines  of  the  hind  tibiae 
shorter  and  sharper. 

5  ,  The  abdomen  is  extremely  smooth  and  the  last  segment  not 
thickly  punctured  as  is  usual  in  this  group.

The  form  is  rather  narrow,  moderately  depressed,  and  scarcely 
tapering  behind.  The  head  is  closely  punctured,  not  carinate  uor 
pitted  upon  the  forehead,  with  the  frojit  margin  of  the  chjpeus 
feebly  reflexed  and  slightly  excised  in  the  middle.  The  proihorax 
is  coarsely  punctured,  narrow  in  front,  with  the  sides  not  much 
curved.  The  scutellum  is  long  and  not  very  blunt,  ^^\^e  elytra  are 
punctate-striate,  with  slight  costse,  the  sides  are  not  strongly 
sinuated  behind  the  shoulders  and  the  apical  angles  are  sharp  but 
not  spinose.  Hhe  piigidmm  is  finely  rugose,  and  the  sides  of  the 
metasternum  and  abdomen  are  rugosely  punctured.  The  sternal 
process  is  prominent,  narrow,  rounded  in  front  but  not  dilated. 
The  front  tibia  is  armed  with  three  sharp  teeth  and  the  liind  tibia 
closely  fringed  with  yellow  hairs  at  the  imier  edge.

In  the  form  of  the  sternal  process  P.  confusa  shows  an  approach 
to  the  genus  Cetonia,  but  this  part,  although  not  dilated  in  front, 
is  not  laterally  compressed,  aud  the  head,  pygidium  and  other 
features  exclude  it  from  that  genus.

]\Ietallic  green,  deep  blue  or  blue-black,  with  the  pronotum, 
scutellum  and  elytra  opaque,  deep  blue,  and  decorated  with  very 
conspicuous  white  spots,  generally  consisting  of  a  pair  upon  the 
clypeus,  a  pair  between  the  eyes,  three  at  each  lateral  margin  of 
the  prothorax,  two  upon  the  disc  and  two  near  the  basal  emargi- 
narion,  three  near  the  inner,  and  three  near  the  outer,  margin  of 
each  elytron,  and  one  in  each  apical  angle.  There  are  also  patches 
on  each  side  of  the  pygidium  and  sternum,  upon  the  femora,  hind 
coxte  and  abdomen,  which  are  more  developed  in  the  male  than  in 
the  female. 

The  form  is  elongate-oval  and  moderately  convex,  aud  the  legs 
are  rather  long.  The  ch/pens  is  long  and  well  punctured,  its 
margins  being  curved  and  gently  refiexed.  The  pronotum  is 
strongly  punctured,  narrow  in  front  and  bisinuate  at  each  side, 
with  the  postei'ior  angles  well  marked.  The  scutellum  is  rather 
lonf^  and  not  very  blunt  at  the  end.  The  ehjlra  are  strongly 
punctured,  gently  sinuated  at  the  sides,  with  a  sharp  cariua  upon 
the  posterior  half  of  each,  and  the  apical  angles  are  sharp.     The

pygidium  is  rugose,  the  metasternum  rugose  and  hairy,  except  in 
the  middle,  and  the  abdomen  very  lightly  punctured.  The  meso- 
stenial  process  is  vei'y  small  and  slightly  transverse,  and  the  middle 
and  Jiind  tihue  have  rather  close  fringes  of  pale  hairs. 

J  .  The  sides  of  the  prothorax  are  very  divergent  and  rather 
straight,  the  apices  of  the  elytra  rather  spinose,  the  abdomen 
strongly  arched  and  deeply  and  broadly  excavated  in  the  middle, 
with  a  median  line  of  white  spots  in  the  basal  part  of  the 
excavation.  The  front  tibiae  and  tarsi  are  rather  elongated,  and 
the  lateral  tibial  teeth  nearly  obsolete.  The  hind  tibiae  are  rather 
attenuated  and  curved,  the  fringe  is  long  and  thick  at  the  ex- 
tremity, and  the  spurs  are  short  and  sharp. 

$  .  The  puncturation  of  the  whole  upper  surface  is  stronger, 
the  sides  of  the  prothorax  are  more  curved,  the  apical  angles  of 
the  elytra  are  not  produced,  the  abdomen  is  convex  beneath,  with- 
out median  spots,  and  the  last  segment,  and  sometimes  those 
preceding,  are  well  punctured.  The  legs  are  normal,  the  front 
tibia  is  armerl  with  three  short  but  sharp  teeth,  and  the  spurs  of 
the  hind  tibiae  are  long  and  blunt.

A  female  of  this  species  in  the  Oxford  Museum  is  of  a  golden- 
bronze  colour. 

This  is  the  most  pecuhar  and  perhaps  the  commonest  and  most 
generally  distributed  Indian  member  of  the  genus.  It  is  remark- 
able for  the  extreme  variability  in  size,  which  can  scarcely  be 
paralleled  in  the  Cetoniin^,  and  also  for  the  great  difference 
between  the  sexes.  Several  of  the  distinctive  features  of  the  male 
appear  quite  foreign  to  the  present  genus,  but  the  female  is  quite 
a  normal  ProtcHia. 

Mr.  jNIaxwell  Lefroy  records  that  it  is  taken  at  the  roots  of  the 
Pipal  Tree  (Eurostigmum  rcligiosum)  and  of  Panicum  spontaneum.

strongly  tridentate.  Hind  tibia  not  digitated.  Maxilla  slender. 
with  a  long  brush  of  hairs  at  the  end. 

The  last  ventral  segment  is  punctured  in  the  female  and  smooth 
in  the  male,  and  the  spurs  of  the  hind  tibia  are  shorter  and 
sharper  in  the  latter. 

This  genus  formed  the  first  section  of  Burmeister's  genus 
Gametis,  but  as  that  name  was  subsequently  restricted  by 
Lacordaire  to  the  second  section,  it  has  been  necessary  to  devise 
a  new  one  for  the  present  group.  It  is  intermediate  between  the 
large  genera  Ghjcyj^hcina  and  Protcetia,  but  had  not  the  meso- 
sternal  process  broadly  dilated  in  front  of  the  middle  coxoe  as  in 
both  those  genera.  The  general  form  and  features  are  those  of 
Protcrtia,  but  the  bilobed  clypeus  without  a  raised  margin  connects 
it  rather  with  Ghjciiphana. 

The  species  of  this  genus  are  very  abundant  where  they  occur, 
and  are  remarkable  for  extreme  variability  of  colour  and  pattern. 
All  of  them  are  spotted  with  white  in  a  similar  manner,  but  the 
ground-colour  is  extraordinarily  inconstant.

The  elytra  are  strongly  puuctate-striate,  with  the  sides  strongly 
siniiated  behind  the  shoulders  and  the  apical  angles  sharp  but  not 
produced.  The  i^ygidium  is  coarsely  punctured  and  setose,  the 
metasternum  rugose  and  hairy,  and  the  abdomen  sparingly,  but 
coarsely,  punctured.  The  mesostemal  process  is  slightly  produced, 
and  broad  but  not  dilated  in  front.  The  front  tihice  are  strongly 
tridentate,  and  all  the  femora  are  fringed  with  long  yellow 
hairs. 

The  coloration  is  very  variable,  but  the  ground-colour  is  black 
and  there  are  usually  the  following  white  markings : — a  pair  of 
minute  spots  upon  the  neck  behind  the  eyes,  a  pair  at  the  middle 
of  the  pronotum,  another  at  the  base  (one  or  both  of  the  latter 
pairs  often  absent)  and  a  lateral  border  on  each  side,  a  spot  at  the 
apex  of  the  scutellum,  from  five  to  eight  spots  on  each  elytron,  and 
two  (frequently  coalescing)  on  each  side  of  the  pygidium.  The 
sides  of  the  sternum  are  broadly  white  and  there  are  two  rows  of 
large  spots  on  each  side  of  the  abdomen. 

The  sexes  are  almost  alike,  but  the  spurs  of  the  hind  tibia  are 
rather  shorter  and  sharper  in  the  male.

Ceylon;  Maueitils. 

The  range  of  variation  in  this  species,  although  exceeded  in 
0.  jucunda,  which  follows,  is  very  remarkable,  extending  not  only 
to  its  coloration  and  the  presence  or  absence  of  the  velvety 
clothing  of  the  upper  surface,  but  to  some  extent  to  its  form  also, 
the  typical  phase  being  usually  smaller  and  more  convex  than  the 
other  varieties,  especially  the  var,  variegata.  The  occurrence  of 
the  latter  form  in  Ceylon  and  the  Madagascan  area,  and  apparently 
nowhere  else,  is  a  remarkable  fact,  presenting  an  interesting 
problem  in  geographical  distribution.  An  exactly  similar  dis- 
tribution is  found  in  the  case  of  Proto'tia  aiiricJialcea,  F.,  already 
dealt  with.  Both  species  must  be  regarded  as  immigrants  into 
Mauritius  from  our  region,  for  the  endemic  Cetoniine  fauna  of 
the  Madagascan  region  is  a  peculiar  one,  and  no  representatives 
of  it  are  found  in  Asia.

Black  and  shining,  with  the  pronotum,  scutellum,  and  elytra 
brick-red  and  opaque,  the  circumference  of  each  elytron  (inter- 
rupted in  front)  and  a  large  discoidal  spot,  and  a  narrow  lateral 
patch  upon  each  side  of  the  pronotum,  black.  There  are  also 
white  markings,  consisting  of  a  narrow  line  at  each  lateral  margin 
of  the  prothorax,  a  minute  spot  at  the  apex  of  the  scutellum,  one 
on  each  mesosternal  epimeron,  four  at  the  outer  margin  of  each 
elytron  (the  fourth  in  the  apical  angle),  and  a  short  transverse 
bar,  more  or  less  interrupted,  crossing  the  suture  before  the 
middle,  four  spots  placed  transversely  upon  the  pygidium,  and 
a  single  or  double  series  on  each  side  of  the  body  beneath. 

It  is  moderately  elongate,  generally  a  little  larger  than  0.  versi- 
color and  jvcunda,  and  clothed  with  yellow  hairs  at  the  sides 
beneath.     The  head  is   long,  finely  and  closely  punctured,  and

bluntly  bidentate  in  front.  The  pronotum  is  rather  evenly  and 
not  closely  punctured,  with  the  sides  gently  curved,  the  hind 
angles  completely  rounded  off,  and  the  base  abruptly  emarginate. 
The  scutellum  is  bluntly  pointed,  and  the  elytra  are  decorated  with 
rows  of  rather  coarse  punctures.  The  pygidium  is  finely  trans- 
versely strigose,  the  metastemum  rugose  at  the  sides,  and  the 
abdomen  scantily  punctured.

The  coloration  above  described  is  that  of  the  typical  phase. 
The  following  varieties  also  occur : — 

Var.  a. 

Entirely  brick-red,  with  two  large  green  patches  at  the  middle 
of  the  pronotum  and  the  white  markings  as  usual. 

Var.  b.  bivittata,  Burm. 

Deep  green  or  black,  with  longitudinal  brick-red  vittse,  viz., 
a  median  one  upon  the  pronotum,  often  continued  upon  the 
scutellum,  a  short  one  in  each  posterior  angle  of  the  pronotum, 
and  one  extending  from  shoulder  to  apex  of  each  elytron,  but 
often  interrupted  in  the  middle.  There  are  also  white  markings 
as  usual.

Type  in  Oxford  Museum. 

Var.  c. 

Entirely  black,  with  the  usual  white  markings. 
Bengal  :  Pusa,  Rungpur ;  Assam  :  Helem. 

The  typical  phase  of  this  species  is  deceptively  like  0.  versicolor, 
var.  a,  but  the  lobes  of  the  clypeus  are  much  less  sharply  pointed 
and  the  scutellum  is  not  black,  as  in  that  species. 

Mr.  Maxwell  Lefroy  reports  that  tliis  beetle  feeds  upon  the 
pollen  of  cotton-flowers,  and  is  also  found  upon  rice,  jute, 
sugar-cane,  and  other  crops. 

147.  Oxycetonia  andrewesi. 

Glycyphana  andrewesi,  Janson,  Trans.  Ent.  Soc.  Land.  1901,  p.  182. 

Deep,  rather  dull,  green  above  and  below,  generally  opaque  on 
the  pronotum,  scutellum,  elytra  and  pygidium ;  the  posterior 
angles  of  the  first,  and  an  oblique  stripe  occupying  the  whole 
central  part  of  each  elytron,  dull  red  (these  red  marks  sometimes 
nearly  or  entirely  absent),  and  with  minute  white  spots  distributed 
as  follows  (but  some  of  them  frequently  wanting) : — a  pair  placed 
transversely  at  the  middle  of  the  pronotum  and  a  second  pair 
anterior  to  it,  a  spot  at  the  apex  of  the  scutellum,  one  at  the 
middle  of  each  elytron,  close  to  the  inner  margin,  and  two  others

behind  it,  one  just  behind  the  shoulder  at  the  outer  margin  and 
two  posterior  to  it,  two  on  each  side  of  the  pygidiuni,  the  sides  of 
the  sternum,  and  a  double  row  on  each  side  of  the  abdomen. 

The  body  is  moderately  short  and  depressed.  The  head  is  rather 
strongly  punctured  and  the  clypeus  strongly  but  bluntly  bilobed. 
The  2^''onotum  is  rather  triangular,  strongly  punctured,  with  the 
hind  angles  traceable  and  the  base  strongly  emarginate  in  the  middle. 
The  scutellwn  is  short,  broad  at  the  base  and  not  very  blunt  at 
the  apex.  The  elytra  are  coarsely  punctate-striate,  the  pygidium 
decorated  with  crescentic  impressions,  the  sides  of  t\i.e  nutasternum 
coarsely  rugose,  and  the  abdomen  coarsely  and  sparingly  punctured. 
The  mesosternal process  is  slightly  produced  and  broad.  The  legs 
and  the  sides  of  the  sternum  and  abdomen  are  rather  thickly 
clothed  with  tawny  hairs. 

6 .  The  abdomen  is  feeby  arched  and  the  apical  angles  of  the 
elytra  are  rather  spinose. 

Length  15-16  mm  ;  breadth  8-9  mm.

Type  in  coll.  Andrewes. 

This  species  is  very  closely  related  to  0.  albopunctata,  F.,  but 
the  head  and  the  pygidium  are  rather  differently  sculptured,  and 
the  mesosternal  process  is  a  little  broader.

Green,  olive,  red,  dark  blue  or  black,  opaque  above  in  the  fresh 
condition,  clothed  thinly  above  aiid  thickly 
beneath  with  tawny  hairs  and  setae,  and 
decorated  with  variable  white  markings, 
generally  consisting  of  a  discoidal  spot  and 
a  marginal  line  on  each  side  of  the  pro- 
thorax,  a  spot  at  the  apex  of  the  scutellum, 
four  at  the  outer  margin  and  one  or  two 
near  the  inner  margin  of  each  elytron,  two 
on  each  side  of  the  pygidium  and  a  double

ihe  sides  very  closely  and  finely  longitudinally  strigose,  the  lateral 
margins  strongly  curved,  the  hind  angles  obliterated,  and  the  base 
gently  but  abruptly  emarginate  in  the  middle.  The  scutellum  is 
moderately  long  and  not  very  blunt,  and  the  elytra  are  strongly 
puDctate-striate,  with  the  sides  deeply  sinuated  and  the  apical 
angles  moderately  sharp.  The  ])i/[/kUwn  and  the  sides  of  the 
inetasternum  are  rugose,  and  the  abdomen  bears  only  a  few  coarse 
punctures.  The  sternal  process  is  slightly  produced  and  rounded 
in  front,  the  front  tibia  is  strongly  and  sharply  tridentate,  and 
the  hind  tibia  has  a  rather  long,  but  not  close,  fringe  of  pale 
yellow  hairs. 

The  sexes  are  similar,  but  the  male  has  the  spurs  of  the  hind 
tibise  shorter  and  sharper  than  the  female.

The  typical  form,  described  above,  is  very  abundant  and  widely 
distributed,  but  remarkable  varieties  more  or  less  localized  occur 
in  India  and  the  southern  part  of  the  enormous  area  of  which  the 
species  is  a  native. 

The  best  marked  Indian  varieties  are  the  following: —

Bright  metallic  green,  sometimes  fiery  red  or  deep  blue,  very 
smooth  and  shining,  but  irregularly  punctured,  and  clothed  with 
yellow  hairs,  which  are  long,  dense  and  decumbent  upon  the 
sternum  and  sides  of  the  abdomen,  short  and  erect  upon  the  rest 
of  the  body. 

The  body  is  long  and  a  little  depressed  above  and  the  legs  are 
moderately  slender.  A  fine  carina  extends  from  the  forehfud  to 
the  extremity  of  the  chjpens,  which  is  excised  and  its  angles 
bluntly  hooked,  and  the  head  is  declivous  and  finely  setose  on 
each  side,  with  longer  and  closer  hairs  between  the  eyes.  The 
pronotum  is  closely  punctured  and  setose,  except  along  the  middle 
line,  but  the  setae  are  very  short  and  not  conspicuous.  The  sides 
are  gently  curved,  the  hind  angles  rounded  but  moderately 
prominent,  and  the  base  deeply  excised  before  the  scutellum. 
The  scutellum  and  elytra  are  thinly  setose,  but  the  clothing 
becomes  much  longer  and  thicker  towards  the  extremity  of  the 
latter.  The  outer  margins  are  very  strongly  sinuated  behind  the 
shoulders  and  converge  very  little  from  that  point,  and  the  inner 
margins  are  elevated  posteriorly  and  produced  into  sharp  spines 
at  the  apices.  The  pi/gidiuni  is  clothed  with  long  hairs,  the 
metastenium  smooth  in  the  middle  and  thickly  clothed  at  the  sides, 
and  the  abdomen  scantily  clothed  except  at  the  edges.  The 
two  terminal  teeth  of  the  front  tibia  are  long  and  sharp  and  the 
middle  and  hind  tibia;  and  tarsi  are  fringed. 

cJ  .  The  front  tarsi  are  nearly  twice  as  long  as  those  of  the 
female.

This  is  one  of  the  most  abundant  Cetoniix,e  throughout  India. 
Messrs.  H.  E.  Andrewes  and  T,  E.  Bell  inform  me  that  in  Southern 
India  it  is  found  in  great  numbers  upon  stems  of  grass,  etc.,  after 
the  autumn  rains,  and  Mr.  Maxwell  Lefroy  states  that  it  is 
injurious  to  juari  (millet)  and  kutki  (a  leguminous  crop),  of 
which  it  damages  the  fiowers.  The  organs  of  the  mouth  are 
peculiar  in  being  much  stronger  and  more  adapted  for  biting  than 
in  normal  Cetoxiin.«. 


EPICOMETIS.  173 


Group  5.    OxYTHYliEIDES. 

The  species  which  compose  this  group  are  ahiiost  all  of  small 
size  and  even  the  largest  do  not  exceed  the  medium  size.  The 
most  constant  characteristic  feature  is  the  long,  narrow,  and  very 
acutely-pointed  scutellum,  the  sides  of  which  are  gently  concave. 
The  excision  of  the  hind  margin  of  the  pronotum,  which  is 
practically  universal  in  the  preceding  group,  is  here  quite  ex- 
ceptional and  it  is  very  commonly  replaced  by  a  projecting  lobe, 
partly  or  entirely  concealing  the  scutellum.  The  clypeus  is 
always  simply  rounded  or  very  gently  emarginate  in  front,  and 
the  sexes  are  not  distinguished  in  any  of  the  Indian  species  by 
marked  external  differences. 

The  group  is  best  represented  in  Africa,  and  the  genus  Clinteria 
is  the  only  truly  Oriental  one.  That  genus  was  associated  by 
Lacordaire  with  Agestrata,  etc.,  in  his  group  Gtmnetides,  while 
Epicometis  and  Leucocelis  were  placed  in  the  true  Cetoniides,  but 
the  multiplication  of  known  species  renders  that  arrangement 
untenable.

This  well-known  and  widely-distributed  insect  is  very  abundant 
in  the  Mediterranean  region,  where  it  inflicts  serious  injury  upon 
various  crops.  It  is  reported  to  injure  peach-blossoms  by 
destroying  the  stamens,  and  in  Greece,  Corsica,  Algeria,  and  other 
vine-growing  countries,  damages  the  buds  of  the  growing  vines 
(^see  Mayet,  Ann.  Soc.  Ent.  Prance,  1894,  p.  5).  These  buds, 
which  contain  a  quantity  of  a  sweet  gummy  substance,  are  perhaps 
only  attacked  in  the  absence  of  ripe  fruit  or  flowers.  The  larvae 
are  said  to  breed  in  the  manure  spread  at  the  roots  of  the  crops.

Black,  shining  beneath  and  opaque  above,  with  bright  j^ellow 
markings  consisting  of  an  oval  patch  at  the  anterior  half  of  each 
lateral  margin  of  the  pronotum,  a  spot  on  each  mesosternal 
epimeron,  an  irregular  transverse  median  patch  and  an  apical 
one  on  each  elytron,  reaching  the  outer  hut  not  the  inner  margin, 
and  a  small  spot  at  each  lateral  edge  of  the  tirst  and  second  ventral 
segments. 

It  is  a  large,  moderately  broad  and  compact  species.  The  clypeus 
is  closely  punctured  aud  rather  strongly  bilobed.     The  'pronotum 


is  convex,  thinly  punctured,  regularly  rounded  at  the  sides  and 
produced  into  a  rather  pointed  lobe  behind.  The  elytra  are 
rather  smooth,  with  a  few  rows  of  fine  punctures,  the  outer 
?nargins  are  moderately  sinuated  and  the  apical  angles  rounded. 
The  pygid'mm  is  closely  strigose  transversely,  the  metasternwn 
deeply  grooved  along  the  middle  and  strongly  and  rugosely 
punctured  at  the  sides,  and  the  ahdomen  strongly  and  irregularly 
punctured,  except  in  tlie  middle.  The  mesostemal  process  is  long 
and  slender,  and  the  front  tibia  is  armed  with  three  very  sharp 
teeth.

Black  and  opaque  above,  with  the  head,  legs  and  lower  surface 
shining,  and  decorated  with  pale  yellow  markings  consisting  of  a 
large  patch  on  each  side  of  the  pronotum,  occasionally  broken  into 
tw'o,  a  large  irregular  median  patch  upon  each  elytron  touching 
the  outer  margin,  a  second  large  patch  occupying  the  apical  angle, 
and  a  row  of  minute  spots  on  each  side  of  the  metasternum  and 
abdomen. 

The  form  is  flat  and  moderately  elongate.  The  ht'ad  is  long, 
closely  punctured  and  a  little  elevated  in  the  middle,  and  the 
clypeus  is  rather  deeply  notched  in  front.  The  pronotuni  is  short, 
narrow  in  front  and  broad  behind,  distinctly  punctured  and 
strongly  lobed  at  the  base.  The  elytra  are  strongly  striate- 
punctate,  with  the  outer  margins  gently  sinuated  and  the  apical 
angles  rounded.  The  pyyidium  is  transversely  strigose,  the  jneta- 
sternum  smooth  in  the  middle  and  coarsely  punctured  at  the  sides, 
and  the  abdomen  coarsely  punctured  at  the  sides  and  very  feebly 
in  the  middle.  The  mesosternal  process  is  long,  laterally  com- 
pressed, and  directed  obliquely  downward,  and  the  front  tibia  is 
armed  with  three  acute  teeth.

Coppery-red,  metallic  indigo,  or  nearly  black ;  opaque  above, 
with  the  head,  legs  and  lower  surface  shining;  decorated  with 
yellow,  orange  or  vermilion  spots,  viz.,  one  or  two  at  the  lateral 
margin  of  the  pronotum  (often  wanting),  one  upon  each  meso- 
sterual  epimerou,  three  (or  less)  upon  each  elytron  (the  first  near 
the  middle,  the  second  at  the  outer  edge  a  little  behiud  the  first, 
and  the  third  at  the  apical  margin),  and  one  on  each  side  of  the 
pygidium.  The  sides  of  the  sternum  and  abdomen  are  similarly 
decorated. 

This  is  one  of  the  largest  species  of  the  genus  and  is  rather 
flattened  and  very  broad  across  the  shoulders.  The  chfpeus  is 
rather  long  and  parallel-sided,  not  very  deeply  notched,  and  closely 
punctured.  The  pronotum  is  strongly  punctured  at  the  front  and 
sides,  narrow  in  front  and  broad  behind,  the  sides  very  feebly 
curved,  and  the  basal  lobe  moderately  long.  The  eh/tra  are 
strongly  punctured  in  longitudinal  lines  and  two  of  the  dorsal 
intervals  are  slightly  raised  posteriorly.  The  pygidium  is  opaque, 
finely  rugose  and  sometimes  slightly  setose.  The  metastemum  is 
coarsely  rugose,  except  in  the  middle,  and  the  abdomen  very 
sparingly  punctured.  The  sternal  process  is  long,  slightly  oblique, 
laterally  compressed  and  rounded  at  the  apex. 

S .  The  two  terminal  teeth  of  the  front  tibia  are  very  sharp 
and  the  third  rather  feeble  and  more  distant.  The  abdomen  is 
not  channelled.

fepot.  a  large  patch  on  each  side  of  the  pygidiiim,  and  a  row  of  spots 
on  each  side  of  the  sternum  and  abdomen. 

The  head  is  closely  punctured,  rather  long  and  deeply  notched  in 
front.  The  prothorux  is  finely  punctured,  attenuated  in  front  and 
strongly  and  rather  sharply  lobed  behind.  The  elytra  are  rather 
parallel-sided,  and  little  narrowed  towards  the  extremity  :  they 
are  coarsely  punctured  in  rows,  with  two  well-marked  costse  upon

In  the  5  there  are  three  sharp,  equidistant  teeth  to  the  front 
tibia.  In  the  S  the  uppei'most  tooth  is  distant  from  the  other 
two  and  much  shorter. 

The  pale  markings  are  liable  to  reduction  and  in  one  specimen 
in  the  British  Museum  have  disappeared  entirely.

Deep  chocolate  colour,  olive-green  or  black,  opaque  above, 
with  the  head,  legs  and  lower  surface  shining  and  metallic  and, 
together  with  the  pygidium,  more  or  less  clothed  with  greyish  set*. 
The  sides  of  the  pronotum  are  narrowly  bordered  with  white, 
there  is  a  pair  of  spots  at  the  middle  of  the  disc  and  sometimes 
an  anterior  pair  placed  a  little  farther  apart ;  the  elytra  are 
decorated  with  a  minute  common  spot  immediately  behind  the 
scutellum  and  about  ten  others  upon  each,  the  lateral  and  apical 
ones  often  larger  than  the  rest  and  sometimes  uniting  together. 
The  first  spot  on  each  elytron  is  closely  adjacent  to  the  thoracic 
lobe.  The  pygidium  has  an  incomplete  white  border,  which 
frequently  breaks  up  into  two  antei'ior  and  two  lateral  spots, 
there  are  large  patches  at  the  sides  of  the  sternum  and  usually  a 
double  row  (sometimes  coalescing)  at  the  sides  of  the  abdomen. 

It  is  compact  in  shape  and  not  much  narrowed  behind.  The 
head  is  densely  punctured,  with  the  chjpens  not  long  and  rather 
feebly  emarginate  in  front.  The  prothorax  is  narrow,  with  the 
sides  angulated  in  the  middle  and  distinctly  diverging  or  nearly 
parallel  behind  ;  it  is  moderately  punctured  and  tlie  basal  lobe  is 
strong.  The  elytra  are  strongly  punetate-striate,  with  rather 
blunt  apical  angles.  The  pygidium  is  rugosely  punctured,  the 
metasiernum  is  rugose  at  the  sides  and  very  sparingly  punctured 
in  the  middle,  and  the  abdomen  almost  smooth.  The  sternal 
process  is  blunt  and  very  little  produced. 

cJ  .  The  abdomen  is  not  hollowed.  The  front  tibia  is  armed 
witii  two  apical  teeth  placed  close  together  and  an  almost  obsolete 
upper  one.

Mr.  E.  E.  Greeu  states  that  this  species  devours  the  blossoms 
of  Crotalaria  and  prevents  the  formation  of  the  seed.

spot  upon  the  posterior  lobe  frequently  united  with  the  median  line, 
which  then  extends  from  the  front  to  the  hind  margin  ;  the  elytra 
bear  variable  scattered  markings,  sometimes  consisting  of  about 
ten  spots,  sometimes  coalescing  into  indefinite  patches,  but  always 
with  an  indication  of  a  transverse  postmedian  fascia  upon  each. 
The  pygidium  is  marked  with  three  spots,  the  middle  one  pro- 
duced towards  the  apex,  and  the  abdomen  has  a  line  of  transverse 
spots  on  each  side. 

It  is  a  small  elongate  species.  The  head  is  densely  granulated 
and  the  chjimis  feebly  notched  in  front.  The  jrrotliomx  is  rather

Black  or  deep  reddish  chocolate,  opaque,  with  the  bead,  legs 
and  lower  surface  sliining ;  decorated  with  deep  yellow  or  orange 
markings,  consisting  of  a  broad  marginal  baud  upon  the  pronotum, 
arising  in  the  front  angles  and  a  little  incurved  near  the  hind 
angles,  but  frequently  more  or  less  abbreviated  and  sometimes 
absent,  a  large  spot  on  each  mesosternal  epimeron,  an  irregular 
transverse  median  band  on  each  elytron,  sometimes  broken  into 
two  spots,  a  spot  anterior  to  this,  and  two  apical  spots,  a  patch 
on  each  side  of  the  pygidium,  and  the  sides  of  the  sternum  and 
abdomen. 

The  form  is  moderately  elongate  and  depressed.  The  head  is 
finely  and  rugosely  punctured  and  rather  deeply  incised  in  front. 
The  prothora.v  is  regularly  curved  at  the  sides,  strongly  narrowed 
in  front  and  moderately  lobed  behind.  The  elijtra  have  rather 
strongly  and  closely  punctured  strise,  they  are  gently  sinuated  at 
the  sides  and  almost  rectangular  at  the  apical  angles.  The 
_l>ygidium  is  finely  strigose,  the  metasternum  is  coarsely  punctured 
at  the  sides,  and  each  ventral  ser/rncnt  has  a  transverse  line  of  large 
punctures.     The  sternal  process  is  short  and  conical.

C.  Idugi  is  a  very  variable  species  in  size,  relative  proportions, 
degree  of  convexity,  and  pattern.  The  yellow  markings  vary 
considerably  in  tint  and  may  become  broken  up,  reduced,  or  partly 
(perhaps  entirely)  absent,  and  in  certain  specimens  those  near  the 
elytral  suture  even  show  a  tendency  to  coalesce  in  a  longitudinal 
direction.     The  following  are  well-marked  varieties  : — 

Yar.  felix,  nov.  This  is  a  well-marked  local  colour-variety  in 
which  the  bright  pigment  has  reached  the  fullest  development.  The 
lateral  yellow  patches  upon  the  pronotum  cover  the  whole  surface 
except  a  nearly  straight  median  stripe ;  the  median  and  posterior 


188  CETONllN.E. 

patches  of  the  elytra  are  all  united,  forniiug  a  broad  C-shaj)ed 
mark  upon  each,  and  the  remaining  anterior  spot  is  almost  united 
to  the  last.  Three  similar  specimens  taken  many  years  ago  by 
Col.  Buckley  are  in  the  British  Museum.  They  were  captured  in 
North  India  but  the  exact  locality  has  not  been  recorded. 

Var.  decora,  Janson.  This  is  smaller  and  narrower  than  the 
typical  form,  the  elytra  are  more  strongly  sculptured,  the  yellow 
border  to  the  prothorax  is  narrow  and  the  elytral  markings  more 
or  less  reduced. 

A'ar.  modesta,  Blanch.  This  is  a  large  variety  in  m  hich  the  yellow

Cliiiteria  caliginosa,  Jamon,  The  Entoimihyist,  xxii,  1880,  p.  101. 

Black,  opaque  above,  with  the  head,  scutellum,  legs  and  lower 
surface  shining ;  decorated  with  white  markings  consisting  of  a 
narrow  marginal  line  on  each  side  of  the  prouotum,  extending  the 
whole  length  but  sometimes  interrupted  in  the  middle,  a  pair  of 
spots  close  together  and  frequently  coalescing  at  the  middle  of 
each  elyti'on,  two  adjoining  the  outer  margin  posteriorly  and  one 
a  little  before  the  apical  angle.  'J'here  is  a  large  spot  on  each  side 
of  the  pygidium  and  the  side  pieces  of  the  metasternum  generally 
bear  a  similar  spot. 

The  fori)i  is  rather  broad,  depressed  above  and  scarcely  narrowed 
behind.  The  head  is  rugosely  punctured,  and  the  margins  of  the 
cliipeus  rather  strongly  retiexed  and  deeply  notched  in  front.  The 
pronotuTii  is  strongly  punctured,  the  sides  regularly  curved  and 
strongly  contracted  in  front  and  the  base  not  strongly  lobed. 
The  eliftra  are  deeply  punctate-striate,  with  two  of  tlie  dorsal 
intervals  raised,  the  sides  are  moderately  sinuated  and  the  apical 
angles  broadly  rounded.  The  pj/i/idhim  is  finely  strigose  and  the 
sides  of  the  metastenium  and  abdomen  are  moderately  punctured. 
The  sieriud  process  is  very  short,  but  compressed  and  rather 
sharply  pointed.

pygidium,  the  sides  of  the  metasternum  and  a  double  row  of  spots 
ou  each  side  of  the  abdomen  are  also  white. 

The  species  is  very  smooth,  rather  convex,  oval  and  slightly 
elongate.  The  head  is  closely  and  finely  punctured,  and  the 
dypeus  is  dilated  at  the  sides  and  rather  narrow  and  sharply 
bilobed  in  front.  The  pronotum  is  finely  and  sparsely  punctured, 
somewhat  narrow  in  front,  strongly  rounded  at  the  sides,  and 
furnished  with  a  rather  pointed  basal  lobe.  The  eh/tra  have  deeply 
impressed  rows  of  strong  punctures,  the  sides  are  gently  sinuated 
behind  the  shoulders  and  the  apical  angles  rounded.  The 
pygidium  is  finely  rugose  in  the  middle,  the  metasternum  coarsely 
punctured  at  the  sides,  and  the  ahdomen  finely  and  thinly  punctured. 
The  sternal  process  is  short  but  pointed.  The  ler/s  are  rather

Shining  deep  metallic  green  or  blue,  decorated  above  with  white 
spots,  as  follows  : — a  minute  one  behind  each  front  angle  of  the 
pronotum,  a  larger  one  before  each  hind  angle  (one  or  both 
frequently  absent),  one  on  each  mesosternal  epimeron,  one  imme- 
diately behind  the  thoracic  lobe  and  common  to  both  elytra,  and 
about  seven  to  eleven  others  upon  each  elytron,  the  principal  being, 
one  behind  the  front  margin,  three  adjoining  the  outer  margin,  and 
three  near  the  inner  margin,  alternating  with  the  last,  the  third 
occupying  the  apical  angle.  The  pygidium  has  a  large  white  patch 
on  each  side,  and  the  sides  of  the  sternum  and  abdomen  are  partly 
or  entirely  barred  with  white. 

The  form  is  oval  and  rather  convex.  The  head  is  densely  punc- 
tured, and  the  dypeus  long,  narrowed  in  front  and  rather  deeply 
notched.  The  pronotum  is  finely  punctured,  narrowed  in  front 
and  provided  with  a  rather  strong  and  pointed  lobe  behind.     The

Clinteria  pumila,  Burm.,  Handh.  Ent.  iii,  1842,  p.  30G. 

Black,  very  smooth  aud  shining,  the  elytra  sprinkled  with  small 
white  spots,  viz.,  upon  each,  three  near  the  sutural  margin  ex- 
tending from  the  middle  to  the  apical  angle,  two  placed  rather 
obliquely  in  the  anterior  part,  live  or  six  placed  irregulax-ly  along 
the  lateral  margin  and  one  sublateral  one  behind  the  middle.  The 
sides  of  the  lirst  three  ventral  segments  bear  transverse  white 
marks  at  the  posterior  margins,  and  the  pygidium  and  sides  of  the 
body  are  thinly  clothed  with  short  tawny  hairs. 

The  species  is  small  and  rather  narrow  in  form.  The  head  is 
densely  and  rugosely  punctured  and  the  dijpeus  rather  feebly 
emarginate  in  front.  The  ]yroHotum  is  very  lightly  ])unctured  upou 
the  disc  and  rather  strongly  at  the  front  and  sides.  The  hind 
angles  are  completely  rounded  and  the  posterior  lobe  is  rather 
obtuse.  The  elijtra  are  strongly  aud  coarsely  punctured  in 
irregular  rows,  the  lateral  margins  strongly  sinuated  behind  the 
shouldei's  and  the  apical  angles  produced.  T]\e pygidium  is  rather 
linely  strigose,  the  metasternum  coarsely  rugose,  and  the  abdomen 
roughly  punctured  at  the  sides.  The  mesosternal  irrocess  is  dis- 
tinctly prominent  and  a  little  compressed  at  the  end.  The  front 
tibia  bears  three  teeth,  the  uppermost  short  and  obtuse,  and  the 
hind  tibia  is  produced  beneath  into  a  single  tooth.

Bengal  (?) ;  Ceylon:  Hambautota (November — T.  B.  Fletcher). 

Type  in  the  Stockholm  Museum. 

This  description  is  made  from  the  type  specimen,  which  is  in 
bad  condition,  but  I  believe  is  specifically  distinct  from  the  two 
preceding.  The  spots  upon  the  elytra  are  as  in  C.  l-i-mamlata, 
but  there  are  none  upon  the  pronotum  or  pygidium  ;  the  clypeus 
is  only  slightly  notched  at  the  margin  and  the  elytra  are  markedly 
produced  at  the  apical  angles.  It  is  very  different  from  the 
variety  of  C.  chloronota  described  by  Mr.  Van  de  Poll  as  probably 
C.  pumila  (Notes  Leyd.  Mus.  xiii,  1891,  p.  184). 

Mr.  Bainbrigge  Fletcher  has  brought  two  specimens  (which 
also  are  not  very  well  preserved)  from  Ceylon.  These  agree  with 
the  type,  except  that  in  one  the  pygidium  bears  two  minute  white 
spots  on  each  side  and  the  elytra  bear  a  common  spot  adjacent  to 
the  scntellum. 

Group  6.    LOMAPTERIDES. 

This  group  consists  of  the  large  genus  Lomaptera,  peculiar  to 
New  Guinea  and  the  neighbouring  islands,  together  with  a  few 
smaller  Oriental  genera.  The  species  are  of  rather  large  size,  flat, 
elongate,  and  remarkably  smooth  and  shining,  without  any  super- 
imposed ornamentation  and  almost  devoid  of  hairs.  The  clypeus  is 
deeply  excised  in  front  and  the  pronotum  is  produced  into  a  strong

with  a  transverse  carina  producing  a  ventral  face.  Mesosternal 
process  forming  a  short  blunt  tubercle :  the  meso-metasternal 
suture  very  distinct.  Front  tibia  armed  with  three  sharp  teeth, 
rather  distant  from  each  other.  Four  posterior  tibiae  without 
internal  fringes  or  external  spines,  but  produced  into  several  sharp 
spines  at  the  extremity.  ]\Iandible  with  the  exterior  lobe  slight 
and  not  long,  the  interior  flange  ratlier  broad  and  strong.  Maxilla 
stout,  witli  the  lobes  short  and  thickly  hairy.  Mentum  very

The  abdomen  and  legs  are  alike  iu  the  two  sexes,  but  the  club 
of  the  antenna  is  longer  in  the  male  and  the  sides  of  the  prothorax 
are  more  divergent  behind. 

There  is  only  one  exceedingly  variable  species  known  in  our

Metallic  blue,  green,  purplish  or  black,  with  the  coxae,  femora, 
mesosternal  epimera,  pygidium  and  sides  of  the  sternum  and 
abdomen  orange-red,  and  sometimes  an  inconspicuous  narrow 
patch  of  the  same  colour  at  the  lateral  edge  of  the  prothorax. 

The  body  is  very  long  and  narrow  and  rather  flat.  The  chjpeus 
is  narrow  and  rather  straight-sided,  lightly  punctured,  but  rather 
more  strongly  in  front.  The  p^'onotum  is  very  finely  coriaceous, 
with  minute  punctures  which  are  most  distinct  at  the  sides.  The 
lateral  margins  are  finely  raised,  the  posterior  angles  well  marked 
but  rounded,  and  the  basal  lobe  rather  pointed  but  not  long.  The 
eh/tra  are  very  long,  smooth,  scarcely  perceptibly  punctured, 
except  at  the  sides,  and  rather  rugose  at  the  extremity.  The 
outer  margins  are  ratlier  feebly  sinuated  behind  the  shoulders,  the 
inner  margins  (at  least  at  the  posterior  half)  strongly  raised,  and 
the  apical  margins  a  little  excised  beside  the  apical  angle,  which, 
is  produced.  T\\e  pyuidium  is  very  short,  broad  and  transversely 
carinated,  with  its  surface  strigose.  The  lower  surface  of  the 
body  is  very  smooth,  but  the  sides  of  .the  metasternum  are  very 
finely  and  densely  punctured. 

The  club  of  the  antenna  is  longer  than  the  footstalk  in  both 
sexes  and  considerably  longer  in  the  male,  although  varying  greatly. 
In  the  latter  sex  the  sides  of  the  pronotum  are  more  divergent 
behind,  the  last  abdominal  segment  is  deeply  emargiuate  in  the 
middle  and  the  ventral  part  of  the  pygidium  correspondingly

Type  not  traced ;  type  of  clilnensis  in  the  British  Museum, 
those  of  gagates  and  withilli  in  the  Oxford  Museum  ;  the  type  of 
nigrita  was  originally  in  the  British  Museum,  but  cannot  now  be 
found;  that  of  samson  in  coll.  Oberthiir. 

This  common  insect  is  remarkably  inconstant  in  size,  colour, 
sculpture,  etc.,  and  tends  to  produce  local  races.  The  var.  samson 
is  a  large  form  with  the  marginal  line  of  the  pronotum  incomplete, 
the  clypeus  as  broad  as  it  is  long,  with  the  sides  gently  curved, 
and  the  pygidium  smooth  in  the  middle.  It  is  doubtful  if  these 
features  are  more  than  individual  aberrations. 

The  beetle  is  commonly  found  in  the  neighbourhood  of  Screw- 
pines  {Pandanus)  and  Mr.  H.  N.  Eidley  tells  me  he  has  never 
seen  them  elsewhere  than  upon  or  flying  round  these.  He  has 
found   them  very   destructive   to   ornamental   Fandanus   shrubs

growing  in  tubs  at  Singapore,  the  woody  stems  being  tunnelled 
through  just  below  the  poiut  of  origin  of  the  branches,  causing 
them  to  die  off.  In  one  of  the  cavities  so  formed,  JNIr.  Eidley 
found  a  cocoon  coutaiuing  a  specimen  of  A<jestmta  orichalcea,  so 
that  the  responsibility  of  its  larva  seems  to  be  established.  The 
larvae  were  found  by  the  late  Col.  C.  T.  Bingham  at  Pandanus 
roots  in  Tenasserim  and  recently  emergetl  beetles  were  crawling 
upon  the  aerial  roots.  One  of  the  larvie  wns  the  prey  of  a  larva 
of  the  great  parasitic  "Wasp,  Scolia  {Triscolia)  riihiginosa,  Fab.,  and 
it  may  be  assumed  that  this  species  is  the  exclusive  food  of  that 
parasite.

Shining  black,  more  or  less  tinged  with  blue,  metallic  green  or 
copper. 

Very  elongate,  flat  above,  straight-sided  and  slightly  tapering 
from  shoulders  to  apex.  The  clypeus  is  strongly  rounded  at  the 
sides,  contracted  before  the  eyes,  deeply  cleft,  and  rugosely  punc- 
tured on  each  side  of  the  middle.  The  pronotum  is  unpunctured, 
except  at  the  sides,  which  are  more  or  less  closely  striated  in  an 
oblique  direction  ;  the  lateral  edges  are  strongly  margined, 
angulate  at  the  middle  and  sinuated  behind,  the  posterior  angles 
are  sharp  and  the  basal  lobe  long  and  bluntly  pointed,  with  a 
slight  longitudinal  impression  at  the  extreme  tip.  The  elytra  are 
quite  smooth  at  the  inner  part,  rather  finely  rugose  at  the  sides 
and  apices,  and  sometimes  have  incomplete  longitudinal  lines  of 
punctures  at  the  outer  part  of  the  disc.  The  sutural  margins  are 
elevated  at  the  posterior  part  and  the  apical  margins  separately 
rounded.  The  pugidiimi  is  moderately  finely  and  transversely 
strigose  but  not  opaque,  and  feebly  impressed  in  the  middle,  and 
the  metasternum  and  abdomen  are  very  smooth  in  the  middle  and 
rather  thinly  punctured  at  the  sides.  The  stenud  process  is  slender 
and  curved. 

The  two  sexes  are  almost  indistinguishable,  but  the  male  has  a 
slight  vestige  of  a  ventral  groove,  the  hind  tarsi  are  a  little  longer 
relatively  than  those  of  the  female,  and  the  tibial  spurs  a  little 
sharper.

In  spite  of  its  abundance  and  familiarity  I  have  not  been  able  to 
obtain  any  information  as  to  the  habits  or  life-history  of  this 
insect.  As  is  commonly  the  case  with  animals  which  are  abundant 
and  distributed  over  a  very  wide  extent  of  country  it  is  exceedingly 
inconstant  in  its  external  features  and  it  is  difficult,  and  perhaps 

o2

impossible,  to  define  its  specific  limits  satisfactorily.  Such  commou 
and  far-ranging  forms  tend  in  particular  localities,  where  they  have 
become  to  any  extent  cut  off  from  the  main  body,  to  produce 
geographical  races,  more  or  less  definitely  characterised  according 
to  the  degree  of  isolation.  The  determination  whether  in  such 
cases  a  particular  form  should  be  called  a  species  or  a  variety  is  an 
arbitrary  one  and  differences  of  opinion  are  to  be  expected.  In 
the  present  case  several  such  forms  may  perhaps  be  distinguished 
within  the  Indian  area,  but  larger  and  more  thoroughly  repre- 
sentative collections  must  be  brought  together  before  they  can  be 
properly  studied.  Although  I  have  examined  some  hundreds  of 
specimens  they  represent  only  a  very  minute  portion  of  the  total 
area  of  distribution.  It  is  perhaps  worthy  of  notice  that  in  the 
Northern  part  of  that  area  the  elytra  have  generally  distinct  rows 
of  punctures  upon  the  disc,  while  in  the  Southern  part  these  are 
absent  (var.  viridia'aeus).  In  some  specimens  the  corrugations  at 
the  sides  of  the  pronotum  become  almost  resolved  into  detached 
punctures  as  in  the  form  next  described,  but  as  I  have  seen  no 
completely  transitional  examples  I  have  treated  the  latter  as  a 
distinct  species.

Black  or  very  deep  blue-black  and  extremely  smooth  and  shining. 
The  form  is  very  much  like  that  of  T.  imllus,  but  is  a  little  broader, 
more  rounded  at  the  sides  and  more  convex  above.  T\\q  jyronotum 
is  distinctly  convex,  less  narrowed  in  front,  and  coarsely  and  not 
very  closely  punctured  at  the  sides,  without  trace  of  striation. 
The  elytra  are  rather  shorter,  less  straight-sided,  less  flattened 
above  and  without  any  lines  of  punctures.  In  other  respects  this 
is  exactly  like  the  preceding  species.

punctured  at  the  sides,  with  the  lateral  margins  distinctly  angu- 
lated  in  the  middle,  and  the  posterior  lobe  not  very  narrow  and 
without  a  longitudinal  impression  at  the  apex.  The  eh/tra  bear 
several  well-marked  rows  of  coarse  irregular  punctures  and  are 
transversely  strigose  at  the  sides  and  apices.  The  piigidium  bears

Only  a  single  male  and  three  female  examples  of  this  species 
are  known.  It  bears  the  closest  resemblance  to  T.  pullus,  but  can 
be  readily  distinguished  by  a  careful  comparison.  It  is  broader 
and  much  more  strongly  sculptured  and  the  striation  of  the 
pygidium  is  so  dense  as  to  produce  a  sooty  unreflecting  surface. 
The  lobe  of  the  pronotum  is  rather  less  narrow  and  without  a 
longitudinal  impression  at  its  extremity.  A  further  distinction 
may  be  found  in  the  different  form  of  the  genitalia  of  the  male.

Bright  metallic  green  above  and  below,  and  very  smooth  and 
shining.      It  is  large,  moderately  elongate,  depressed  above  and 

straight-sided.  The  ch/ijeus  is 
very  coarsely  punctured,  with  the 
margins  raised,  and  the  vertex  is 
smooth  in  the  middle.  The  ^j>'0- 
notum  is  rather  coriaceous  and 
extremely  finely  punctured,  except 
in  the  region  of  the  front  angles, 
where  the  punctures  are  very 
coarse.  The  sides  are  contracted 
in  front,  where  they  are  consider- 
ably depressed,  obtusely  angulated 
at  the  middle,  and  produced  out- 
wards at  the  hind  angles,  which 
are  sharp.  The  basal  lobe  is 
minutely  rounded  at  its  apex. 
The  eh/tra  have  a  few  very  minute 
and  inconspicuous  punctures, 
which  are  a  little  more  apparent  at  the  sides,  and  the  apical  and 
posterior  lateral  margins  are  feebly  rugose  ;  the  outer  edges  are 
scarcely  sinuated  and  the  apices  are  excised  near  the  angles,  which 
are  spinose.  The  j^yciidium  is  strigose,  the  metastemum  coarsely 
transversely  punctured  at  the  sides,  and  each  ventral  segment  has 
a  median  line  of  setigerous  punctures,  except  the  last,  which  is 
entirely  punctured.     The  mesosiernal  process  is  strong,  curved  and

Division  I.— Section  2.  CEEMASTOCHILIIS'A. 

This  group  is  very  closely  related  to  the  previous  division  of 
the  Cetoniini,  but  in  response  to  a  different  manner  of  life  its 
members  have  to  a  great  extent  lost  the  characteristic  aspect  of 
the  Subfamily.  They  are  very  various  in  form  but  generally 
sombre-coloured  and  possessing  well-marked  pecuharities  in  their 
mouth  structure.  They  are  not,  like  the  great  majority  of  the 
insects  previously  dealt  with,  flower  frequenters  and  suctorial,  but 
in  general  are  nocturnal  and  occur  under  stones  and  in  similar 
situations,  many  of  them  being  inmates  of  the  nests  of  Ants  or 
Termites.  The  actual  nature  of  their  food  is  unknown  but  it  is 
evidently  of  a  solid  nature,  the  organs  of  the  mouth  being  adapted 
for  biting  and  without  brushes  of  soft  hairs. 

The  mandibles  are  no  longer  thin  and  blunt  externally  but 
strongly  chitiuised,  with  the  extremities  strong,  sharp  and  directed 
towards  each  other,  and  the  internal  membranes  are  much  reduced. 
The  maxiilie  end  in  two  or  three  strong  sharp  teeth  and  are  clothed 
only  with  stiff  bristles :  the  palpi  have  the  basal  joints  very  small 
and  the  terminal  one  rather  large.  The  mentum  is  broad  and 
rather  smooth,  not  at  all  or  but  little  emarginate  at  the  front 
margin  and  generally  tumid  beneath,  its  palpus  having  the  basal 
joints  minute  and  the  terminal  one  rather  large.  The  basal  joint 
of  the  antenna  is  generally  enlarged.  The  mesosternal  epimera 
are  enlarged  and  reach  the  dorsal  surface :  and  the  scutellum  is 
extremely  sharp  at  the  apex  with  its  sides  concave.  The  outer 
margins  of  the  elytra  are  generally  strongly  sinuated  behind  the 
shoulders.  The  last  pair  of  spiracles  is  frequently  situated  upon 
tubercular  prominences,  and  sometimes  the  preceding  one  or  two 
pairs  also.  The  mesosternal  process  is  absent  or  rudimentary. 
The  front  tibia)  are  usually  bidentate,  and  the  front  tarsi  in  the 
most  characteristic  genera  are  inserted  so  far  back  as  to  appear 
when  seen  from  above  to  consist  of  only  three  or  four  joints. 

The  male  is  furnished  with  long  branched  antlers  in  O'oliathopsis 
and  with  pads  of  hair  upon  the  hind  tibiae  in  certain  species  of 
Coenochilus.  In  most,  the  abdomen  is  arched  or  excavated  beneath 
in  this  sex. 

In  spite  of  tlieir  typically  dull  colouring,  bright  coloured  species 
are  found  in  the  genus  Macro7na,and  ISjiUopJiori's  has  white  patches

which  reproduce  the  markings  of  species  of  Proicetla.  Again, 
while  some  liave  the  legs  long,  there  are  others  in  which  the  tarsi 
are  contracted  to  such  an  extent  as  to  consist  of  only  four  visible 
joints  (genus  Callinomes). 

Owing  to  their  aberrant  structure  these  forms  are  generally 
regarded  as  constituting  a  group  of  higher  rank  than  the  groups 
of  Ceto:^iini,  but  the  iuquilines  of  Ants  and  Termites  in  very 
diffei-ent  tribes  of  beetles  are  subject  to  certain  profound  modi- 
fications which  tend  to  obscure  their  real  affinities  and  suggest 
relationships  which  are  only  apparent.  It  is  possible  that  the  homo- 
geneity of  the  Cbemastochilina  may  to  some  extent  be  due  to 
convergence  brought  about  by  similarity  of  environment.  AVest- 
wood  considered  the  group  to  be  most  nearly  related  to  DipJognatha 
and  Protcptia,  and  Macroma  as  forming  a  link  with  those  genera  ; 
but  in  my  opinion  the  point  of  contact  is  to  be  found  rather  with 
the  OxYTHYREiuES,  through  such  genera  as  Spilophorus  and 
Cymopliorus,  and  Macroma  is  rather  an  isolated  form.

The  following  species  is  only  the  second  assigned  to  the  genus. 


178.  Platysodes  jansoni,  sp.  n. 

Jet-black,  very  smooth  and  shining.  The  body  is  flat  and  long, 
tapering  slightly  behind.  The  Jiead  is  broad,  with  the  eyes  not 
very  large  or  prominent,  aud  the  chipeus  short,  rounded  at  the 
sides  and  straight  at  the  front  margin,  which  is  distinctly  reflexed. 
There  are  two  shallow,  punctured  depressions 
between  the  antennal  orbits.  The pronotum 
is  half  as  broad  again  as  it  is  long,  strongly 
rounded  at  the  sides,  with  the  posterior 
angles  obliterated  and  the  base  distinctly 
excised  before  the  scutellum.  The  elytra 
are  rather  broader  at  the  shoulders  than  the 
prothorax,  gently  sinuated  at  the  lateral 
margins  and  roundly  narrowed  to  their 
extremities.  There  is  a  narrow  depression 
at  the  anterior  part  of  the  suture,  the  latter 
is  bordered  on  each  side  by  a  deep  stria, 
and  there  is  a  very  strong  lateral  furrow  on 
each  elytron,  not  reaching  the  front  or 
hind  margin.  The  intervening  space  is 
smooth  and  bears  only  a  few  very  minute 
punctures.  The  pyijidium  is  almost  semi- 
circular in  shape  and  has  a  strong  carina  all  round,  which  divides 
it  into  nearly  equal  dorsal  and  ventral  faces.  These  are  thinly  and 
rather  minutely  punctured  and  the  dorsal  surface  is  opaque  and 
gently  carinate  longitudinally  in  the  middle.  The  meiastermim 
and  abdomen  are  smooth  in  the  middle  and  feebly  rugose  at  the 
sides. 

The  unique  specimen  described  appears  to  be  a  male.

Type  Cremastochilus  maculatus,  G.  &  P. 

Type,  Spilophorus  pJagosus,  Westw.  (Africa). 

Range.  Africa  and  India. 

Form  rather  depressed,  broad  and  parallel-sided,  with  short 
legs.  Clypeus  short  and  broad  ;  the  eyes  prominent.  Prothorax 
broadly  transverse,  contracted  in  front  and  strongly  emarginate 
in  front  of  the  scutellum.  Scutellum  large,  not  long  but  very 
acute.  Elytra  strongly  sinuated  behind  the  shoulders.  Meso- 
sternum  not  produced.  Front  tibia  feebly  bidentate;  middle  and 
hind  tibiiB  strongly  toothed  at  the  middle  of  the  outer  margin 
and  digitate  at  the  end.  All  the  tarsi  short  and  compact.  Mentum 
broad  in  front  and  feebly  emarginate.  Maxillary  lobes  forming 
two  very  strong  teeth.  Mandible  with  a  strong  hooked  tooth  at 
the  end.     Last  pair  of  abdominal  spiracles  elevated. 

6  .  The  abdomen  is  hollowed  beneath. 

According  to  Mr.  Peringuey,  Spilophorus  lives  in  South  Africa 
in  the  nests  of  Passerine  birds,  where  both  the  larva  and  adult 
feed  upon  the  nest-material  or  excrement.  The  black  and  white 
colouring  of  all  the  species  appears  to  be  a  protective  assimilation 
to  such  an  environment,  but  if  the  same  habit  prevails  in  India  it 
is  not  invariable,  for  one  of  the  two  species  has  been  found  in  an 
Ants'  nest. 

Kegarding  the  two  Indian  species  (hitherto  treated  as  one)  as 
constituting  the  type  of  Westwood's  genus,  Dr.  Kraatz  made  a 
new  genus  for  the  African  forms.  This  is  based  on  very  slight 
grounds,  and  since  the  anatomical  details  described  and  figured  by 
\Vestwood  are  those  of  the  African  and  not  the  Indian  species,  I 
consider  it  incorrect  to  treat  the  latter  as  his  type.  The  confusion 
of  the  two  Indian  species  is  a  further  objection  to  this.

Type,  Cipnophorus  vndatus,  Kirby  (S.  Africa). 

Eange.  Africa,  India,  Indo-China. 

Small,  compact,  elongate,  and  more  or  less  clothed  with  hairs  or 
setae.  Clypeus  short  and  broad,  with  the  front  margin  straight 
and  reflexed.  Eyes  very  prominent.  Basal  joint  of  antenna  not 
large.  Prothorax  transverse,  broadly  emarginate  before  the 
sciitellum.  Last  pair  of  spiracles  very  prominent,  spinose.  Meso- 
sternum  very  narro\\'  between  the  middle  coxae  and  scarcely  pro- 
duced, forming  a  right-angled  lamina.  Legs  of  moderate  length, 
the  front  tibia  rather  slender  and  armed  with  two  equal  blunt 
teeth  placed  close  together  at  the  extremity.  Tarsi  5-jointed 
and  slender. 

The  species  here  described  is  the  first  discovered  in  non- 
African  localities.  The  chief  home  of  the  genus  is  tSoutheru  Africa, 
where  the  species  are  rather  numerous. 

181.  Cymophorus  pulcliellus,  sp.  n.     (Plate  II,  fig.  5.) 

Shining  black,  with  two  large  bright  red  patches  upon  each 
elytron,  placed  one  before  the  middle  and  the  other  behind  it, 
approximately  quadrate  in  shape  and  touching  the  outer  margins, 
where  they  are  united  by  a  narrow  band. 

The  body  is  long,  narrow  and  parallel-sided,  clothed  with  short, 
coarse,  silvery  set^e  upon  the  head,  the  front  and  sides  of  the 
pronotum,  the  shoulders,  the  p^'gidium  and  the  lower  surface 
(except  along  the  middle).  The  head  is  entirely  rugose  and  the 
pronotum  strongly  and  coarsely  punctured — less  closely  upon  the 
posterior  half.  It  is  distinctly  broader  than  it  is  long,  the  sides 
are  strongly  contracted  towards  the  front  and  slightly  towards 
the  hind  margin,  which  is  approximately  straight,  with  the  angles 
distinct  but  obtuse  and  the  middle  broadly  excised.  There  is  a 
large  deep  pit  close  to  the  hind  margin  on  each  side.  The  scutellum 
is  very  smooth,  and  the  ehjtra  are  strongly  punctured  at  the  front, 
lateral  and  hind  margins,  and  have  besides  a  few  irregular  longi- 
tudinal rows  of  punctures.  There  is  a  punctured  pit  near  each 
shoulder,  a  longitudinal  depression,  containing  several  fine  striae, 
near  the  sutural  margin,  and  a  transverse  impression  at  the  middle 
of  each  elytron  occupying  the  space  between  the  two  red  patches. 
The  sides  of  the  elytra  are  prominent  at  the  shoulders,  strongly 
sinuated  behind  them  and  rounded  at  the  extremity.  The 
pygidium  is  large,  triangular,  and  rather  closely  hairy.  The 
middle  of  the  metastemum  and  abdomen  are  smooth  and  shining, 
and  the  sides  hairy.  The  last  two  ventral  segments  are  bent 
downwards.  The  front  tibia  is  bent  outwards  at  the  extremity 
and  terminates  in  two  very  closely  approximate  teeth.

S .  The  abdomen  is  narrowly  channelled  beneath  and  the  hind 
tibia  bears  a  rather  long  fringe  of  hairs  within. 

2  •  The  outer  spur  of  the  middle  tibia  and  both  spurs  of  the 
hind  tibia  are  long  and  strongly  curved,  but  not  very  sharp.  The

Genus  PARAPILINURGUS,  nov. 

Type,  Parapilinurgas  variegatus,  sp.  n. 

Range.  That  of  the  species  following. 

Body  rather  short,  with  the  elytra  much  broader  than  the 
prothorax,  and  the  whole  body  clothed  witli  opaque  earthy  matter. 
Head  small,  with  prominent  eyes,  and  clypeus  broad,  with  the 
anterior  margin  \ery  strongly  reflexed.  Prothorax  rather  small, 
strongly  narrowed  in  front  and  regulai'ly  rounded  at  the  sides  and 
base.  Elytra  rather  parallel-sided,  strongly  sinuated  behind  the 
shoulders.  Pygidium  nearly  vertical,  scarcely  convex.  Terminal 
spiracles  scarcely  elevated.  Mesosternum  narrow  and  not 
prominent  between  the  coxae.  Legs  slender,  the  front  tibiae 
minutely  and  sharply  bidentate,  the  middle  and  hind  tibiae  sharply 
digitate  at  the  end  and  armed  with  a  strong  spine  at  the  middle 
of  the  outer  edge.  Tarsi  five-jointed.  Basal  joint  of  antenna  not 
much  enlarged,  club  rather  large.  Mentum  tumid  beneath,  with 
the  anterior  part  flattened  and  the  front  margin  broad  aud  feebly 
notched  in  the  middle.  Maxilla  short  and  stout,  with  its  outer 
lobe  forming  a  strong,  but  not  acute,  tooth.  Last  joint  of  all  the 
palpi  long.     Mandible  armed  with  a  short  triangular  tooth. 

This  new  genus  is  very  near  the  African  FUhinrgus,  from  which 
it  differs  by  its  peculiar  shape,  narrow  in  front  aud  broad  behind, 
the  very  slight  antecoxal  process  of  the  prosternum,  scarcely 
elevated  terminal  spiracles  and  not-concave  mentum. 


182.  Parapilinurgus  variegatus,  sp.  n. 

Black,  clothed  above  and  beneath  with  a  brown  earthy  matter, 
irregularly  speckled  with  pale  markings,  among  which  a  slight 
transverse  angulate  mark  is  distinguishable  behind  the  middle  of 
each  elytron.  The  surface  is  coarsely,  shallowly  and  rugosely 
punctured. 

The  form  is  short,  with  the  elytra  broad  and  flattened  and 
the  prothorax  narrow.  The  head  is  rugose  aiid  tlie  clypeal  margin 
entire  and  very  strongly  reflexed.  The  2»'onot urn  is  much  narrower 
than  the  elytra,  about  as  long  as  it  is  broad,  not  very  convex, 
strongly  narrowed   anteriorly,  with   the  front  angles  acute,  the

sides  and  base  being  strongly  and  continuously  rounded.  The 
elytra  are  broad  at  the  shoulders,  with  the  sides  strongly  sinuated 
and  almost  parallel  from  the  sinuation  to  the  extremity.

the  terminal  tooth  sharp  and  nearly  straight,  and  the  internal 
membrane  well  developed.  Maxilla  short,  armed  with  three  blunt 
teeth.  Mentum  very  tumid  beneath,  with  the  front  margin 
straight. 

c?  .  Head  furnished  with  a  pair  of  branched  horns  arising  from

Black  and  shii)ing,  with  the  sides  of  the  metasternuin  and  the 
pygidiuin  and  sides  of  the  abdomen  beneath  more  thinly  clothed 
with  tawny  hair. 

It  is  a  small  and  only  moderately  elongate  species,  with  the 
prothorax  rather  small  and  the  shoulders  very  prominent.  The 
head  is  closely  and  coarsely  punctured,  with  the  chjpev.s  dilated  to 
the  front  margin  and  feebly  bilobed,  and  the  vertex  less  coarsely 
punctured  and  bearing  a  slight  but  sharp  median  tubercle  between 
the  eyes.  The  pronotum  is  small,  transverse,  strongly  and  uni- 
formly punctured,  with  the  sides  strongly  but  bluntly  aiigulated 
at  the  nnddle,  the  hind  angles  rather  sharp  and  prominent,  and 
the  base  broad  and  nearly  straight.  There  is  an  impressed  median 
line  npon  the  posterior  half,  and  a  small  basal  pit  near  each  hind 
angle.  The  scuteUum  bears  a  few  punctures.  The  elytra  bear 
each  three  smooth  longitudinal  costae,  a  little  punctured  towards 
the  posterior  end ;  the  intervals  bear  rows  of  crescentic  punc- 
tures, which  become  simple  and  irregularly  scattered  towards  the 
base.  The  sides  and  apices  are  strigose.  The  shoulders  are  very 
prominent  and  there  is  a  profound  marginal  sinuation  behind  each. 
The  2Vjgidium  is  strongly  and  deeply  punctured  and  clothed  with 
tawny  hair.  The  lower  surface  is  smooth  along  the  middle  line, 
punctured  and  hairy  at  the  sides,  those  of  the  nietasternum  rather 
closely.  The  terminal  spiracles  are  very  prominent  and  sharp. 
The  legs  are  rather  slender,  but  the  front  tibia)  are  moderately 
broad,  armed  with  two  sharp  teeth  at  the  extremity  and  a  vestige 
of  an  upper  one  near  the  middle. 

S .  The  abdomen  is  longitudinally  channelled  beneath.

This  description  is  drawn  up  from  a  single  male  specimen, 
badly  preserved,  in  the  Calcutta  Museum.  In  this  example  the 
abdomen  and  pygidium  are  reddish.  The  species  is  closely  related 
to  C.  striatus,  Westw.,  from  Hong  Kong,  in  which  the  sides  of 
the  body  have  an  opaque  grey  bloom  beneath,  instead  of  being 
clothed  with  hair.

with  the  eyes  large  and  prominent  and  the  front  margin  of  the 
clypeus  broad  and  feebly  excised.  The  pronotum  is  subcircular, 
with  the  angles  obliterated  and  the  sides  strongly  and  evenly 
curved,  but  more  strongly  approximating  in  front.  The  disc  is 
convex,  with  scattered  punctures,  which  are  stronger  and  denser 
in  the  anterior  part,  a  fine  impressed  longitudinal  line  in  the 
middle  and  a  large  impression  at  each  side  of  the  base.  The 
scutellum  is  finely,  rather  rugosely,  punctured.  The  elytra  are  not 
very  long,  broad  at  the  base  and  narrowing  towards  the  apex  ; 
they  are  scarcely  punctured,  except  at  the  base,  but  there  are  four 
broad  and  deep  longitudinal  sulci  upon  each,  the  outermost  finelv 
rugose  in  its  posterior  part.  The  pygklium  is  finely  punctured 
and  pubescent,  and  the  last  spiracle  on  each  side  is  elevated. 
The  abdomen  is  smooth  in  the  middle.  The  legs  are  long  and 
the  front  tibice  rather  sharply  bidentate. 

<S .  The  abdomen  is  strongly  arched  and  deeply  and  broadly

186,  Ccenochilus  solidus,  sp.  n. 

Black  and  shining,  with  the  metasternum  thickly  clothed  with 
a  velvety  yellow  pubescence,  and  the  head,  pygidium  and  sides  of 
the  abdomen  more  finely  and  inconspicuously  clothed.  The  body 
is  robustly  built,  elongate  and  parallel-sided,  with  the  tibiae  not 
long  but  the  tarsi  slender.  The  Jiead  is  coarsely  rugose  and  the 
pronotum  strongly  punctured  all  over,  but  more  strongly  and 
closely  upon  the  anterior  half.  It  is  subcircular,  with  the  base 
very  short,  the  hind  angles  completely  obliterated  and  the  sides 
not  regularly  curved,  but  rather  abruptly  widened  before  the 
middle.  There  is  a  median  longitudinal  channel  from  before  the 
middle  to  the  base  and  a  deep  impression  at  each  end  of  the  base. 
The  sciUellum  is  rather  finely  strigose.  The  elytra  are  not  sloping 
at  the  shoulders  nor  tapered  to  the  extremities,  but  are  strongh' 
sinuated  at  the  outer  margins,  deeply  striated,  distinctly  but  thinly- 
punctured  on  the  dorsal  part,  and  finely  and  closely  rugose  at  the 
sides  and  apices  and  in  the  third  stria.  The  pygidium  is  finely 
striated  concentrically  and  the  abdomen  transversely  strigose. 

J  .  The  abdomen  is  deeply  excavated  in  the  middle,  the  front 
tibiae  bluntly  bidentate  at  the  end,  and  the  hind  tibiae  feebly  dilated 
and  fringed  at  the  inner  edge  of  the  posterior  half.

Ccenocliilus    pygidialis,    Janson,*    Irans.   Ent.    Soc.   Lond.   1901, 
p.  185. 

Black,  rather  closely  and  uniformly  clothed  with  reddish  setae 
beneath,  and  closely  sculptured  and  not  shining  above.  The  body 
is  of  rather  compact  form,  but  the  legs  are  moderately  long.  The 
clypeus  is  very  deeply  and  coarsely  rugose,  and  broad  and  gently 
emarginate  in  front.  The  eyes  are  large  and  prominent.  The 
pronotum  is  strongly  and  closely  punctured,  very  convex  and  sub- 
circular,  and  a  little  attenuated  in  front.  There  is  a  lightly  impressed 
longitudinal  groove  and  the  base  is  almost  straight  in  the  middle, 
with  a  marginal  groove  which  is  enlarged  on  each  side.  The 
scutellum  and  elytra  are  everywhere  finely  rugose  and  the  latter 
have  each  three  broad  longitudinal  furrows.  The pygidium  is  very 
prominent,  with  a  strong  nearly  sti'aight  transverse  carina  in  the 
middle ;  the  surface  above  the  carina  is  nearly  flat  and  finely 
rugose,  and  that  below  it  convex,  shining,  sparingly  punctured 
and  lightly  carinate  longitudinally.  The  front  tibia  is  mode- 
rately stout  and  ends  in  two  very  bluntly  rounded  teeth  placed 
close  together.  The  terminal  spii-acles  are  only  very  feebly 
elevated. 

The  unique  type  is  a  female,  and  the  peculiar  form  of  the 
pygidium  is  probably  characteristic  of  that  sex.

the  front  tibia  armed  externally  with  two  minute  and  rather  distant 
teeth.  Tarsi  4-jointed,  very  short  and  compact,  with  minute 
claws.     Terminal  spiracles  elevated. 

J  .  The  abdomen  is  a  little  excavated  beneath  and  the  front 
tibia  bears  a  long  apical  process  beneath. 

This  genus  shows  all  the  peculiar  features  of  the  Ceemasto- 
CHiLiNA  at  their  greatest  development.  The  remarkable  box- like 
structure  formed  by  the  enlarged  mentum  and  basal  joint  of  the 
antenna,  which  completely  shut  in  the  delicate  head-appendages, 
the  thickening  of  the  tarsi  and  reduced  number  of  their  joints,  are 
parts  of  a  protective  adaptation  similar  to  that  found  in  beetles 
of  many  different  families  which  inhabit  the  nests  of  Ants  or 
Termites.

(n.  syn.). 

Black,  with  the  upper  surface  of  the  head  and  prothorax  and 
the  basal  quarter  of  the  elytra  (except  the  humeral  callus)  brick- 
red,  a  narrow  stripe  of  the  same  colour  extending  backwards  to 
beyond  the  middle  near  the  outer  margin  of  each  elytron.  The 
upper  surface  is  opaque  and  the  lower  surface,  with  the  pygidium 
and  legs,  shining  black. 

It  is  a  large  elongate  species,  rather  fiat  above.  The  Jiead  and 
pronotum  are  rather  finely  punctured,  the  sides  of  the  clypeus 
nearly  vertical,  and  the  front  margin  nearly  straight  and  scarcely 
reflexed.     The  protlwrax  is  almost  circular,  a  little  broader  than

long,  with  the  front  margin  straight  and  the  posterior  margin 
regularly  rounded.  The  scutellum  is  strongly  punctured  and  the 
elytra  sparingly  and  irregularly  punctured,  without  striae  or  costae  ; 
they  are  considerably  broader  across  the  shoulders  than  the  pro- 
thorax,  very  feebly  sinuated  at  the  sides  and  a  little  narrowed  to 
the  extremities.  The  pygkl'mm  is  small,  coarsely  and  thickly 
])unctured  and  a  little  depressed  iu  the  middle.  The  metasternum 
is  rather  strongly  punctured,  the  abdomen  feebly  rugose  and  the 
terminal  spiracle  on  each  side  strongly  elevated.  The  tihkn  are 
rather  long  and  a  little  incurved,  and  all  the  tarsi  extremely  short 
and  compact.

196.  Callinomes  pusillus,  sp.  n. 

Black,  smooth  and  not  very  shining,  coarsely  and  moderately 
closely  punctured  above  and  beneath. 

The  body  is  long  and  narrow  and  rather  depressed.     The  head 

is  closely  punctured,  Avith  the 
eyes  very  small  and  inconspicuous, 
the  front  margin  of  the  clypeus 
slightly  excised  and  reflexed,  and 
the  mentum  and  the  basal  joint 
of  the  antenna  very  large,  feebly 
punctured  and  shining.  The 
pronoturn  is  strongly  punctured, 
not  very  convex,  rather  broader 
than  long  and  a  little  narrower 
than  the  elytra.  Its  posterior 
half  is  semicircular  and  the  an- 
terior half  slightly  narrowed  to 
the  front,  with  the  sides  nearly 
straight.  The  ■scutellum  bears  a 
few  large  punctures  and  the  elytra  are  thickly  and  closely  punc- 
tured, the  punctures  being  elongate  and  showing  a  tendency  to 
form  longitudinal  rows ;  the  sides  are  reflexed  but  not  sinuated. 
The  pyyidiimi  is  broad  and  convex  and,  like  the  metasternum  and 
abdomen,  is  coarsely  pitted.  The  last  pair  of  spiracles  is  very 
slightly  elevated.  The  legs  are  very  short,  the  front  tibia'  feebly 
bident'ate,  and  the  middle  and  Jdnd  tibia'  each  bear  a  sharp  spine 
at  the  middle  of  the  outer  edge.  All  the  tarsi  are  very  short,  but 
the  articulations  are  distinct. 

cJ  .  The  abdomen  is  shallowly  grooved  beneath  and  the  front 
tibia  bears  a  hook-like  ventral  process  at  its  extremity.

Macroma  maculicollis,  IJ'estw.,  I.  c.  p.  13,  j)l.  vi,  fig.  10. 

Black,  with  the  head,  pronotum  and  front  legs  partially  or 
entirely  orange  ;  the  scutellum,  side  pieces  of  the  metasternum 
and  sides  of  the  hind  coxae  generally  bright  yellow,  and  the 
sides  of  the  third  and  fourth  abdominal  segments  deep  red. 
The  pronotum  has  commonly  a  black  median  line  and  a  large 
black  patch  on  each  side,  the  latter  frequently  reduced  to  two 
spots. 

The  form  is  moderately  long.  The  Jiead  is  coriaceous,  the 
clypeus  nearly  straight  in  front,  and  the  mentum  vertical  in  front 
and  rather  deeper  than  it  is  broad.  The  jJt'otho rax  is  rather  short, 
not  much  narro^^■ed  in  front,  w  ith  the  sides  well  punctured  and 
the  basal  margin  gently  rounded.  The  eh/tra  are  distinctly  and 
irregularly  punctured,  with  their  sutural  margins  a  little  depressed 
in  front  and  elevated  behind,  the  posterior  end  being  finely  rugose. 
The  piKjidium  is  very  lightly  strigose,  with  a  median  longitudinal 
carina  and  a  blunt  tubercle  on  each  side  of  it.  The  sternal  jyrocess 
is  very  short  and  rather  broadly  dilated,  the  sides  of  the  meta- 
uternum  are  sparingly  punctured,  and  the  abdomen  is  nearly 
smooth.

Ceylon. 

This  species,  though  very  variable  in  colouring,  is  otherwise 
constant.  The  prothorax  appears  in  every  stage  between  uniform 
red  and  uniform  black.  The  name  Macroma  javanica  was  given 
to  a  dark  form  in  which  only  the  head  and  a  narrow  lateral  border 
to  the  pronotum  are  black.  The  darkest  variety  appears  to  be 
peculiar  to  Ceylon,  from  which  island  I  have  seen  no  representative 
of  any  other  form.  This  variety  is  mentioned  by  Mr.  Van  der 
Poll  (Notes  from  the  Leyden  Museum,  xvii,  1895,  p.  132).     A

specimen  was  found  in  a  red  ants'  nest  at  Sigirva,  Ceylon,  by 
Mr.  R.  C.  Punnett.  It  is  remarkable  that  this  very  widely-distributed 
species  should  be  found  only  in  the  north-east  and  extreme  south 
of  our  region.

Black,  with  the  clypeus  and  an  angular  prolongation  between 
the  eyes,  the  lateral  and  hind  margins  of  the  pronotum  (except  a 
small  black  spot  in  the  middle  of  each  lateral  border),  the  sides  of 
the  metasternum  and  hind  coxse,  and  the  antenual  club  yellow. 

The  shape  is  very  convex  and  moderately  elongate.  The  liead 
is  coriaceous,  with  the  front  of  the  clypeus  rounded  and  the 
mentum  horizoutal.  The  pronotum  is  rather  sparingly  and  finely 
punctured,  rather  transverse,  with  the  sides  strongly  bisinuated 
and  the  basal  margin  slightly  angulated  in  the  middle.  The  elytra 
are  uniformly  convex  and  finely  and  irregularly  punctured,  except 
at  the  extremities,  which  are  strigose.  The  pygidium  is  smooth, 
w  ith  a  sharp  median  carina  and  a  rounded  boss  on  each  side.  The 
sternal  process  is  very  short,  the  metasternum  slightly  strigose  and 
pubescent  at  the  sides,  and  the  abdomen  almost  smooth. 

cJ.  The  abdomen  is  strongly  arched  and  deeply  grooved,  and 
the  two  penultimate  segments  are  closely  punctured  and  hairy  in 
the  middle.

Black,  with  the  clypeus  and  an  angular  prolongation  between 
the  eyes,  the  lateral  margins  of  the  pronotum  (except  a  small 
median  black  spot  on  each  side),  and  the  elytra  (except  narrow 
sutural  and  lateral  margins  and  a  broad  posterior  margin)  yellow. 
There  is  a  slight  expansion  of  the  black  lateral  margin  just  beyond 
the  middle,  a  black  patch  sometimes  appears  upon  the  suture 
opposite  this,  and  in  some  specimens  a  transverse  band  is  formed 
by  their  fusion. 


220  CETONIIN^. 

The  form  is  rather  slender.  The  head  is  coriaceous,  with  its 
front  margin  rounded  and  very  gently  curved  upwards,  and  the 
mentum  horizontal.  The  pronotum  is  distinctly,  but  sparingly  and 
irregularly,  punctured,  rather  narrow  in  front,  with  the  lateral 
margins  strongly  bisinuate  and  the  basal  margin  nearly  straight 
but  slightly  augulated  in  the  middle.  The  elytra  are  extremely 
sparingly  punctured,  with  the  suture  a  little  depressed  in  front 
and  elevated  behind  :  the  apical  part  is  finely  strigose  and  limited 
in  front  by  a  sinuated  carina.  The  py<iidium  is  shining  and  nearly 
smooth,  with  a  median  longitudinal  carina  and  a  blunt  tubercle  on 
each  side.  The  sternal  process  is  small,  very  feebly  produced  and 
dilated,  the  sides  of  the  metasternum  are  finely  strigose  and  hairy, 
and  the  abdomen  is  feebly  rugose  at  the  sides. 

The  front  tibiae  are  sharply  bidentate  in  the  female,  but  the 
upper  tooth  is  absent  in  the  male,  in  which  also  the  hind  tibia  is 
sUghtly  curved  and  drawn  out  into  a  single  sharp  spine.  The 
abdomen  is  deeply  channelled  in  this  sex.

Shining  black  above  and  beneath,  with  the  antenme  and  the 
head,  except  at  the  sides  behind  the  eyes,  bright  orange. 

Elongate,  broad  at  the  slioulders  and  very  tapering,  depressed 
in  the  scutellar  region  and  very  smooth.  The  clypeus  is  coriaceous, 
parallel-sided  and  nearly  straight  in  front,  and  the  mentum  hori- 
zontal. The  pronotum  is  vei'y  feebly  punctured  at  the  sides,  narrow 
in  front  and  broad  behind,  with  the  sides  nearly  straight,  the  hind 
angles  almost  acute  and  the  base  trisinuate.  The  elytra  are  almost 
smooth,  with  a  sharp  jagged  carina  before  the  apex.  The  pyyidium 
is  finely  strigose,  with  an  impression  at  the  apex,  a  sharp  median 
carina  and  a  spinose  elevation  on  each  side.  The  sternal  process  is 
very  broad  and  flat,  the  sides  of  the  metastermnn  are  finely  strigose, 
and  the  abdomen  is  almost  smooth.  The  fifth  ventral  segment  is 
very  broad,  thinly  punctured  posteriorly  and  slightly  deflected. 
The  external  edge  of  the  hind  tibia  is  produced  and  bifid  at  the 
end  and  the  tarsi  are  short  and  thick. 

Only  female  specimens  seem  yet  to  have  been  found.

Shining  black,  with  the  head  and  prothorax  crimson,  the  latter 
decorated  with  three  small  black  spots  placed  in  a  triangle  on 
each  side  and  the  front  and  hind  margins  very  narrowly  black. 

Rather  short,  broad  at  the  shoulders,  with  the  upper  surface 
very  convex  and  strongly  depressed  in  the  region  of  the  scutellum. 
The  Jiead  is  coriaceous,  with  the  clypeus  rather  transverse,  parallel- 
sided  and  almost  straight  in  front,  and  the  mentum  horizontal. 
The  pronotum  is  punctured  at  the  sides,  narrow  in  front  and  broad 
behind,  with  the  posterior  angles  well-marked  and  the  base  very 
obtusely  angulated  in  the  middle.  The  scutellum  is  acute  at  the 
apex,  but  not  produced  as  in  M.  melanopus,  nigripennis,  &e.,  and 
the  elytra  are  almost  impunctate,  with  the  apical  area  hmited  by 
a  zigzag  carina  in  front  and  feebly  strigose  ;  the  anterior  half  of 
the  suture  is  depressed  and  the  posterior  half  elevated.  The 
pygidium  is  rugose,  slightly  bilobed  at  the  apex,  with  a  sharp 
median  carina  and  an  elevation  on  each  side  produced  backwards 
as  a  sharp  spine.  The  lower,  like  the  upper  surface,  is  almost 
smooth,  and  the  fifth  ventral  segment  is  twice  the  width  of  those 
preceding  it  and  bent  downwards  at  an  angle  to  them.  The 
sternal  process  is  very  broad.  The  external  face  of  the  hind  tibia 
is  produced  and  bifid  and  the  hind  tarsus  is  short  and  thick. 

The  male  is  apparently  unknown.

222  CETONIIX^. 


Division  II.  VALGINI. 

This  is  a  very  well-defined  group,  one  of  the  chief  characteristics 
of  which  is  the  diminutive  size  of  its  members.  Many  are  very 
small  indeed,  and  the  largest  are  little  larger  than  the  smallest 
species  found  in  the  other  groups  of  the  CEXoyiix^.  Another 
conspicuous  feature  is  the  almost  universal  clothing  of  scales, 
which  are  sometimes  fiat  and  close,  sometimes  long  and  erect. 
The  head  is  long  and  narrow  and  capable  of  being  folded  closely 
beneath  the  sternum,  being  then  concealed  from  above  by  the 
prominent  front  part  of  the  pronotum.  The  latter  is  generally 
distinctly  narrower  than  the  width  of  the  body  across  the  shoulders, 
with  the  base  rounded  and  not  emarginate  in  the  middle.  The 
scutellum  is  small,  its  sides  convex  and  its  apex  not  very  acute. 
The  elytra  ai'e  generally  short  and  broad,  not  at  all  cut  away  at 
the  sides,  rounded  at  the  extremities  and  leaving  exposed  the 
pygidium  and  propygidium,  which  are  broad  and  prominent,  the 
last  pair  df  spiracles  in  most  genera  being  borne  upon  very  pro- 
minent tubercles  at  the  sides  of  the  latter  segment.  The  front 
tibia  is  toothed  along  the  entire  outer  edge,  bearing  generally 
five,  but  sometimes  only  three  teeth.  The  front  coxae  are  very 
prominent  and  contiguous  and  the  middle  and  hind  coxae  widely 
separated.  The  mesosternum  is  not  produced.  The  tarsi,  with 
few  exceptions,  are  very  long  and  slender.  The  anterior  abdo- 
minal segments  are  short  and  the  fifth  segment  relatively  very 
wide.  The  antennae  and  the  organs  of  the  mouth  do  not  differ 
from  those  of  the  Cetoniini. 

The  sexual  differences  are  very  various.  In  certain  forms  the 
extremity  of  the  abdomen  is  produced  in  the  female  into  a  long 
and  slender  style  or  ovipositor. 

A  European  species,  Vah/us  hemipterus,  is  the  only  representa- 
tive of  the  group  of  which  the  habits  are  known.  M.  Fallou 
(Bull.  Soc.  Eut.  France,  18S0  and  1888)  records  that  he  found

Type,  Valgus  argillaceus,  Hope. 

Range.  ludia,  Burma,  Siam,  and  the  Malayan  Kegion. 

Body  of  variable  shape,  but  frequently  long  and  narrow,  clothed 
with  short  flat  scales,  the  legs  not  long,  the  front  tibia  armed 
with  three  very  strong  teeth  occupying  the  whole  outer  edge,  the 
first  joint  of  the  hind  tarsus  shorter  than  the  succeeding  one. 
Clypeus  moderately  long,  contracted  in  front  of  the  eyes,  broadly 
rounded  in  front,  with  the  angles  detlexed,  sometimes  sharp  but 
not  conspicuous.  First  joint  of  the  antenna  large,  produced  beyond 
the  point  of  articulation  of  the  second  joint.  Prothorax  rather 
narrow,  the  episterna  produced  freely  forward  and  forming  witli 
the  front  coxsd  a  deep  cavity  for  the  reception  of  the  head. 
Pronotum  bearing  two  strong  ridges,  prominent  and  generally 
united  in  front.  The  propygidium  and  pygidium  are  broad  and 
exposed,  the  terminal  spiracles  scarcely  elevated,  except  in 
0.  momeitensis.  The  fifth  ventral  segment  is  twice  the  length  of 
the  anterior  segments. 

The  sexual  differences  are  various  and  often  very  great.  Usually 
the  female  is  relatively  narrower  than  the  male,  but  in  0.  gravis 
it  is  broader.  The  propygidium  is  frequently  horizontal  and  more 
or  less  produced  in  the  female  and  there  is  sometimes  a  colour 
difference.     The  hind  tarsi  of  the  male  are  longer.

Dark  brown,  clothed  with  not  very  large  or  close-lying  greyish 
scales  above,  and  with  larger  and  denser  scales  beneath. 

The  body  is  long  and  narrow.  The 
chjpeus  is  rounded  in  front  and  strongly 
contracted  in  front  of  the  eyes  ;  the  basal 
joint  of  the  antenna  is  large.  The  prono- 
tum  is  long,  with  a  median  furrow  bordered 
on  each  side  by  a  straight  carina,  which  is 
produced  in  front  into  a  strong  tubercle 
directed  forwards  and  upwards,  and  bearing 
two  other  smaller  erect  tubercles  placed  at 
equal  distances  posteriorly.  The  sides  are 
strongly  curved  and  each  bears  three  equi- 
distant tubercles,  the  two  posterior  ones 
,  minute,  and  there  is  another  tubercle  placed 

^^g-  ^^-^i^JZ  o'^  each  side  of  the  disc  before  the  middle. 

The  base  is  strongly  rounded  and  the  hind 
anglesare  very  slightly  prominent.  The  scutelhan  is  long  and  narrow . 
The  elytra  are  narrowed  from  base  to  apex  and  striated,  the  scales 
being  arranged  in  well-marked  bands.  The  hind  margin  of  the

204.  Oreoderus  bhutanus,  sp.  n. 

Dark  brown,  clothed  densely  with  scales,  which  are  brown  or 
buff  above  and  greyish  beneath,  the  elytra  usually  decorated  with 
a  pale  spot  in  the  middle  of  each. 

The  body  is  very  elongate  and  depressed.  The  2^>'othora,v  is 
long,  rather  parallel-sided,  with  a  prominent  loop  in  front,  and 
distinctly  dilated  at  the  posterior  angles,  each  lateral  margin 
having  two  distinct  indentations.  The  dorsal  carinas  do  not  reach 
the  middle  and  there  is  a  slight  oblique  carina  on  each  side  before 
the  middle.  The  scutelliim  is  long,  narrow  and  rather  acute  at 
the  apex.  The  eh/tra  are  long  and  the  lateral  costse  not  tubercu- 
late  at  the  posterior  end.  The  pro2'>ygidium  is  produced  into  a 
short  lobe  and  notched  in  the  middle,  and  the  pygidlum  is  not 
large. 

c? .  In  addition  to  the  pale  spot,  the  front,  hind  and  sutural 
margins  of  the  elytra  are  sometimes  lighter  in  colour,  and  also 
the  margins  of  tlie  propygidium.  The  hind  tarsi  are  longer  than

210.  Oreoderus  gravis,  sp.  n. 

Chocolate-colour,  rather  densely  clothed  with  round  scales, 
except  upon  the  scutellum  which  is  smooth  and  shining,  those  of 
the  lower  surface,  pro])ygidium  and  pygidium  being  large  and 
grey,  while  those  of  the  head,  pronotum  and  elytra  are  smaller 
and  darker,  but  relieved  with  paler  scales  at  the  base,  apex, 
sutural  margins  and  middle  of  the  elytra. 

It  is  a  large,  broad  species.  The  dypeus  is  not  long,  well 
rounded  in  front  and  armed  with  a  minute  bitid  process  at  the 
middle  of  the  front  margin.  The  prothorax  is  relatively  small 
and  narrow,  witli  the  sides  rounded  in  front  and  nearly  parallel 
behind,  the  base  rounded  and  the  disc  bearing  a  carinate  loop,  a 
little  constricted  before  the  middle  and  produced  beyond  it,  aiul  a 
very  short  oblique  carina  on  each  side.  The  scutellum  is  ratlier 
broad.  The  elytra  are  broader  conjointly  than  their  length,  with 
their  lateral  cosije  sharply  prominent  at  the  end.  The  legs  are 
not  long,  the  two  terminal  teeth  of  the  front  tibia  are  very  large 
and  sharp,  and  the  third  tooth  is  very  short.

Body  elongate,  depressed  above  and  clothed  with  scales.  Legs 
short ;  the  front  tibiae  acutely  tridentate,  the  teeth  rather  close 
together  and  the  uppermost  one  placed  at  about  the  middle  of  the 
outer  edge ;  all  the  tarsi  very  short,  thick  and  compact,  and  the 
claws  short  and  apposed.  Clypeus  long,  parallel-sided  and  emar- 
ginate  at  the  end,  with  the  angles  reflexed  and  blunt.  Prothorax 
not  dilated  beyond  the  middle,  with  a  nearly  complete  longitudinal 
median  furrow,  bordered  by  two  prominent,  nearly  parallel  earinse. 
Scutellum  moderately  long.  Terminal  spiracles  borne  by  pro- 
minent tubercles  situated  at  the  hind  margin  of  the  propygidium. 
Eifth  ventral  segment  as  long  as  the  three  preceding  together. 

The  sexes  are  alike,  but  the  abdomen  of  the  male  is  very  slightly 
arched  beneath. 

Only  the  following  new  species  is  known.  It  seems  probable 
from  its  peculiar  structure  and  aspect  that  it  is  an  inhabitant  of

Black  or  pitchy  brown,  clothed  above  and  beneath,  but  not 
densely,  with  flat  greyish  scales. 

The  chjpeus  is  quadrate,  broad  in  front,  where  it  is  notched  at 
an  obtuse  angle,  the  corners  being  strongly 
reflexed  and  strongly  bent  outwards.  The 
l^rotliorax  is  elongate,  broad  in  front,  with 
the  median  part  ])rominent,  the  sides  sinu- 
ated  and  rather  converging  behind,  the 
base  being  broadly  rounded.  The  longi- 
tudinal carinjB  extend  almost  the  entire 
length  of  the  pronotum,  and  there  are  two 
large  tubercles  on  each  side  situated  at 
the  corners  of  a  transverse  parallelogram. 
The  scufelhnn  is  triangular.  The  eh/t'ra 
are  deeply  striated  and  the  interstices 
clothed  with  rows  of  uniform  grey  scales.

Genus  XENOREODERUS,  nov. 

Type,  Oreoderus  humilis,  Gestro. 

Range.  The  Oriental  Eegion. 

Body  stout  and  compact,  clothed  with  scales  and  hairs,  some  of 
Avhich  form  erect  tufts  upon  the  pronotum  and  propypidium. 
Clypeus  moderately  broad  in  front  and  strongly  contracted  before 
the  eyes.  Prothorax  narrower  than  the  combined  width  of  the 
elytra,  not  bearing  produced  dorsal  carinse  anteriorly.  8cutellum 
moderately  short.  Terminal  spiracles  borne  upon  prominent 
tubercles  at  the  hind  margin  of  the  propygidium.  Legs  moderately 
slender,  the  front  tibia  armed  with  three  strong  teeth,  tlie  tarsi 
slender  and  the  first  joint  of  the  hind  tarsus  equal  in  length  to 
the  second. 

I  have  detected  no  sexual  differences  in  the  specimens 
examined. 

This  genus  is  intermediate  in  its  chai'acters  between  Oreoderus 
and  Dasyval/jus.  Its  species  are  probably  rather  numerous,  Vahjvs 
py(jmceus,  G.  &  P.,  being  one  of  them.  This  species  is  quoted  in 
the  Munich  Catalogue  as  inhabiting  "  India  orientalis."  Its  exact 
habitat  was  unknown  to  the  original  describers,  but  it  was  found 
by  Dr.  Schaum  (see  Ann.  iSoc.  Ent.  Prance,  1844,  p.  ^99)  to  be  a 
Malayan  species.

Deep  red-brown,  with  the  head,  legs,  scutelluin  and  margins  of 
the  pronotum  aud  elytra  generally  black  :  irregularly  clothed  with 
not  close-lying  yellow  scales,  which  are  frequently  larger  aud 
closer  at  the  sides,  base  and  middle  of  the  pronotum,  in  the  middle 
of  each  elytron  and  iiear  the  scutellum. 

The  form  is  stout  and  the  legs  moderately  long.  The  dyp)eus 
is  rounded  in  front.  The  pronotum  is  scarcely  longer  than  it  is 
wide,  convex,  longitudinally  grooved  at  the  middle,  prominent  in 
front,  with  the  sides  nearly  straight  and  parallel,  but  strongly 
curved  in  front,  the  base  strongly  rounded  and  the  hind  angles 
very  obtuse.  There  are  four  inconspicuous  tufts  near  the  base 
and  two  near  the  middle.  The  scutellum  is  very  feebly  elongate. 
The  elytra  are  not  tufted,  the  propygidium  and  pygidi^im  are 
rather  closely  scaly  and  the  former  bears  a  pair  of  tufts  at  the 
hind  margin.  The  three  teeth  of  the  front  tibia  are  sharp,  and  all 
the  tarsi  are  slender,  with,  the  joints  of  equal  length.

Black  or  very  deep  chocolate-colour,  clothed  with  fine  setae  and 
decorated  with  orange  or  yellow  scales,  which  are  numerous  and 
closely  packed  in  the  male,  forming  a  very  conspicuous  pattern, 
and  in  the  female  fewer,  less  close  and  inconspicuous. 

The  chjpeus  is  long,  distinctly  bilobed  and  not  closely  punctured. 
The  pronotum  is  moderately  long,  bell-shaped,  ^^"ith  the  sides  and 
base  regularly  and  gently  curved.  The  dorsal  carinse  are  nearly 
parallel  and  tufted  near  the  middle  and  at  the  hinder  extremities. 
The  scutellum  is  moderately  long  and  blunt.  The  eJytj^a  are  deeply 
striated  and  separately  rounded  at  the  end.  The  iiropygidium  is 
tufted  on  each  side  of  the  middle  and  the  terminal  spiracles  are 
moderately  prominent.  The  front  tibia  is  broad  and  armed  with 
five  strong  teeth  and  the  basal  joint  of  the  hi^id  tarsus  is  twice  as 
long  as  the  second  joint.  The  upper  side  of  the  hind  femur  is 
clothed  with  grey  scales. 

c? .  The  pronotum  is  covered  with  yellow  scales,  except  at  the 
hinder  median  part,  and  the  elytra  have  each  a  large  median  yellow 
patch  and  usually  a  smaller  and  paler  one  external  to  it,  a  patch 
adjoining  the  scutellum,  another  in  the  sutural  angle  and  several 
inconspicuous  longitudinal  lines  of  scales  following  the  intervals 
between  the  striae.  The  greater  part  of  the  lower  surface  of  the 
body  is  clothed  with  pale  yellow  scales.  The  three  distal  teeth  of 
the  front  tibia  are  long  and  acute  and  the  hind  tarsus  is  about 
half  as  long  again  as  the  tibia. 

$  .  The  yellow  markings  of  the  male  are  only  vaguely  repre- 
sented by  a  few  greyish  yellow  scales.  The  body  is  more  elongate, 
the  propygidium  more  extended,  and  the  pygidium  has  a  smooth 
flattened  ventral  plate.  The  front  tibia  is  broader  than  that  of 
the  male  and  all  its  teeth  very  blunt.  The  hind  tarsus  is  stout 
and  only  a  little  longer  than  the  tibia.

Very  deep  brown  or  black,  shining,  but  clothed  with  minute 
erect  setae,  with  two  minute  patches  of  decumbent  ochreous  scales 
placed  transversely  at  the  middle  of  each  elytron. 

The  body  is  moderately  elongate  and  the  lerjst  stout,  with  rather 
short  tarsi,  the  hind  ones  rather  flattened  and  the  first  joint  not 
long  but  twice  the  length  of  the  second.  The  sides  of  the 
prothorax  are  almost  straight,  gently  converging  towards  the  front, 
where  they  are  a  little  rounded.  There  are  two  straight  parallel 
doT'sal  ridges  ending  at  about  the  middle  of  the  disc,  where  they 
bear  a  pair  of  tufts,  and  there  are  four  similar  tufts  near  the  base. 
The  scuteUum  is  moderately  large  and  long  and  the  ehjtra  are 
deeply  striated,  with  slight  tufts  at  the  shoulders  and  apical  calli. 
There  are  two  distant  tufts  at  the  hind  margin  of  t\\Q  propiigkUum 
and  the  terminal  spiracles  are  slightl}'  prominent.  The  front  tibia 
is  rather  short  and  broad,  with  the  1  st,  3rd  and  5th  teeth  strong 
but  not  very  sharp,  and  the  2nd  and  4th  hardly  perceptible.

behind,  but  a  little  irregular,  and  strongly  rounded  in  front,  and  the 
hind  angles  are  sharp  but  not  acute.  There  are  two  well-marked 
dorsal  carina?  extending  almost  from  front  to  hind  margin,  a  deep 
oblique  fovea  on  each  side  at  the  middle,  extending  to  the  lateral 
margin,  and  four  tufts  near  the  hind  margin.  The  scvtclhim  is 
not  long.  The  ehjtra  are  finely  striated,  slightly  tufted  at  the 
shoulders,  and  separately  rounded  at  the  hind  margins.  The 
terminal  s/nradea  are  moderately  prominent.  The  front  tibia  is 
broad  and  armed  with  five  strong,  broad  and  nearly  equal  teeth.

Type  in  the  British  Museum. 

This  species  very  closely  resembles  D.  luetuosns,  Gestro,  from 
which  it  differs  by  the  more  evenly  toothed  front  tibia,  longer 
tarsi  and  the  more  rounded  sides  of  the  prothorax.  By  analogv 
with  D.  dohrni,  Kolbe,  it  seems  probable  that  the  unknown  males 
of  both  these  species  are  more  brightly  adorned  than  the  female. 

218.  Dasy valgus  militaris,  sp.  u. 

Black,  with  the  last  two  segments  of  the  abdomen  scarlet  above 
and  beneath.  The  body  is  rather  thinly  clotlied  with  yellow  scales, 
but  those  at  the  hind  angles  of  the  prothorax,  above  and  beneath, 
upon  the  mesosterual  epimera,  the  front  borders  of  the  elytra  and 
along  the  middle  of  the  propygidium  and  pygidium  are  larger  and 
closer,  forming  bright  orange-coloured  patches. 

The  clypms  is  long,  shining,  strongly  punctured,  and  feebly 
notched  at  the  middle  of  the  front  margin.  The  sides  of  the 
prothorax  are  strongly  rounded  in  front  and  nearly  parallel 
behind,  the  hind  angles  are  very  obtuse  and  the  base  strongly 
rounded.  The  dorsal  carinoe  are  gently  curved,  converging  to

flowers. 


221.  Dasyvalgus  carbonarius,  sp.  n. 

Black  and  shining,  but  finely  rugose  and  excessively  finely  and 
sparingly  clothed  with  dark  setfe,  with  four  small  inconspicuous 
patches  of  erect  seta?  placed  in  a  transverse  line  across  the  middle 
of  the  elytra,  each  patch  immediately  followed  by  a  few  greyish 
scales.     The  scales  and  set?e  are  easily  lost. 

The  body  is  moderately  broad  and  the  legs  are  slender.  The 
head  is  very  closely  punctured  and  the  forehead  sliglitly  carinate. 
The  proihorax  is  strongly  and  densely  pitted  and  rugose,  narrow, 
with  the  front  angles  acute,  the  sides  gently  rounded  and  a  little 
contracted  behind,  and  the  hind  angles  slightly  rounded  off. 
There  are  two  sharp,  nearly  parallel,  dorsal  carinse  extending  from 
the  front  almost  to  the  base,  two  short  outer  ridges  near  the 
middle,  parallel  to  the  first  (but  sometimes  absent),  and  a  short 
oblique  ridge  in  each  hind  angle.  The  scuteUiim  is  a  little  elon- 
gate, and  the  eli/tra  are  irregularly  striated,  with  a  slight  tuft  of 
black  setae  at  each  shoulder,  and  the  hind  margins  are  separately 
rounded.  The  terminal  spiracles  are  very  sharp  and  prominent, 
and  there  are  two  small  distant  tufts  at  the  hind  margin  of  the 
pi-opygidiitm,  which,  with  the  pijgidium  and  lower  surface  of  the 
body,  is  closely  covered  with  large  annular  punctures.  The  front 
tibia  is  armed  with  five  equidistant  teeth,  the  1st,  3rd,  and  5th  a 
little  longer  than  the  others.  The  basal  joint  of  the  hind  tarsus 
is  as  long  as  the  two  succeeding.

I  have  seen  a  good  series  of  males  but  only  a  single  female, 
which,  in  spite  of  its  different  aspect,  due  chiefly  to  the  prominent 
pygidium  and  very  much  shorter  tarsi,  I  beheve  I  am  right  in 
associating  with  them.  It  was  brought  by  Doherty  from  the  Ruby

interstice. 

The  body  is  robust  and  the  legs  moderately  long.  The  ch/peits 
is  shining  and  feebly  bilobed.  The  sides  of  the  prothora.v  are 
strongly  rounded  in  front  and  nearly  straight  behind  :  the  hind 
angles  are  obtuse  and  the  base  strongly  rounded.  The  dorsal 
carinae  are  nearly  parallel  and  end  in  a  pair  of  tufts  near  the  middle 
of  the  disc,  and  there  are  four  posterior  tufts.  The  scntellum  is 
long  and  narrow.  The  ehjtra  are  deeply  striated,  scarcely  tufted, 
and  separately  rounded  at  the  hind  margins.  The  ^propygidium 
bears  two  slight  tufts  behind  and  the  terminal  spiracles  are

Chestnut-red,  clothed  all  over  with  coarse  erect  yellowish  setae, 
each  elytron  marked  more  or  less  evidently  with  a  small  black 
spot,  having  a  few  yellow  scales  adjoining  it. 

It  is  a  small  species,  with  the  prothorax  relatively  rather  large. 
The  head  bears  two  tufts  upon  the  vertex.  The  sides  of  the  pro- 
thorax  are  nearly  straight,  slightly  converging  to  the  front,  where 
the  angles  are  prominent.  There  are  two  strong,  nearly  parallel, 
dorsal  cariuae,  prominent  at  the  front  margin  and  terminating 
behind  in  two  well-marked  tufts  behind  the  middle  of  the  pro--

Black,  clothed  beneath,  rather  uniformly  but  not  densely,  with 
minute  yellow  scales,  and  above  with  larger  scales  closely  packed 
upon  the  propygidium  and  pygidium  and  less  uniformly  upon  the 
pronotum  and  elytra,  where  they  are  interspersed  with  spots  and 
patches  of  dark  scales  and  setfe.  The  yellow  scales  of  the  elytra 
are  most  numex'ous  near  the  suture  and  in  a  patch  placed  behind 
the  middle  of  the  outer  edge,  and  there  is  a  round  patch  of  dark 
scales  on  each  side  of  the  suture  before  the  middle. 

The  body  is  a  little  elongate  and  the  legs  are  slender.  The 
diipeus  is  notched  at  the  front  margin  and  there  are  two  tufts 
placed  transversely  upon  the  forehead.  The  prothorax  has  the 
sides  strongly  rounded  in  front,  nearly  parallel  behind,  the  hind 
angles  distinct  and  the  base  regularly  rounded.  The  dorsal  caringe 
are  parallel,  moderately  sharp  in  front,  and  terminate  in  two

angles  rather  blunt.  The  dorsal  carinre  are  strong,  parallel,  and 
very  prominent  in  front,  and  end  in  slight  tubercles  near  the 
middle  of  the  disc.  The  scutellum  is  rather  narrow  and  acute,  and 
the  elytra  bear  minute  tufts  of  setje  at  the  shoulders  and  are 
separately  rounded  at  the  hind  margins.  The  propygidium  is 
broad  and  prominent,  with  two  strong  tubercles  at  its  hinder 
margin,  but  with  the  terminal  spiracles  scarcely  elevated.  The 
front  iihia  is  rather  broad,  and  armed  with  five  prominent  and 
nearly  equidistant  teeth,  the  1st  and  3rd  very  long.  The  tarsi 
are  moderately  long,  with  the  basal  joint  of  the  hind  foot  nearly 
twice  the  length  of  the  second. 

I  have  found  no  sexual  difference  in  a  good  series  of  specimens.

This  is  the  smallest  known  Indian  Cetoniid  beetle.  It  is  closely 
related  to  DasyvaJgus  penicillatus,  but  in  addition  to  its  smaller 
size,  is  more  elongate,  with  the  sides  of  the  prothorax  less  rounded 
in  front  and  the  terminal  spiracles  scarcely  prominent.

but  most  closely  packed  at  the  front,  inner  and  bind  borders. 

There  are  traces  of  a  dark  spot  at  the  middle  of  each  elytron, 
perhaps  conspicuous  in  well-preserved 
specimens. 

It  is  a  small  species  with  long  slender 
legs.  The  profhorax  is  rather  long, 
with  the  sides  very  gently  curved  and 
converging  to  the  front  angles,  which 
are  acute  :  it  is  strongly  grooved  longi- 
tudinally in  the  middle,  but  scarcely 
carinate.  The  basal  margin  forms  a 
very  obtuse  angle  in  the  middle.  The 
scutellum  is  rather  large,  moderately 
broad,  and  smooth  and  shining.  The 
elytra  are  rather  deeply  striated  and 
separately  rounded  at  the  posterior 
margin.  The  terminal  spiracles  are 
moderately  prominent  and  there  are  two 
slight  and  rather  distant  tufts  of  setse 
at  the  hind  margin  of  the  propiigidium. 

The  front  tibia  is  moderately  broad,  with  the  1st  and  3rd  teeth 

long  and  slender,  and  the  2nd,  4th  and  5th  very  short  and  blunt. 

The  basal  joint  of  the  liind  tarsus  is  a  little  longer  than  the  second.

231.  Dasyvalgus  kanarensis,  sp.  n. 

Chestnut-red,  clothed  closely  and  uniformly  beneath,  and  irre- 
gulai'ly  above,  with  yellowish  scales.  There  is  a  patch  of  dark 
scales  before  the  middle  of  each  elytron,  and  the  light  scales  are 
densest  immediately  before  and  behind  this  and  at  the  front,  inner 
and  hind  borders  of  each  elytron.  The  pronotum  is  fairly  well 
covered  and  bears  two  median  and  four  basal  tufts  of  erect  setse, 
and  the  propygidium  and  pygidium  are  densely  scaly,  the  former 
bearing  at  its  hind  margin  two  strong  tufts  of  a  darker  colour. 

The  body  is  slightly  elongate  and  the  legs  are  moderately  slender. 
The  clypeus  is  narrow  and  entire.  The  pronotum  has  the  sides  well 
rounded  in  front  and  very  little  diverging  behind,  the  posterior 
angles  rounded  off  and  the  base  regularly  curved  ;  there  is  a 
deep  median  longitudinal  groove,  but  its  sides  are  not  strongly 
carinate.  The  scutellum  is  smooth,  shining,  and  rather  long ;  and 
the  elytra  are  deeply  striated,  with  the  hind  margins  separately 
rounded.  The  terminal  spiracles  are  very  prominent  but  blunt. 
The  front  tibia  is  stout  and  its  1st  and  3rd  teeth  very  long  and 
sharp,  the  2nd  and  5th  strong  and  the  4th  small  but  moderately 
sharp  ;  there  is  a  very  deep  notch  between  the  2nd  and  3rd  teeth. 
The  first  four  joints  of  the  Jiind  tarsve  are  nearly  equal  in  length, 
but  the  basal  joint  is  stouter.

Black  or  deep  chocolate-brown,  clothed  with  scales  of  the  same 
colour,  with  grey  scales  upon  the  legs,  lower  surface,  the  sides 
and  middle  of  the  pronotum,  the  scutellum  and  transverse  bands 
common  to  both  elytra  at  the  base,  middle  and  apex,  the  middle 
band  pointing  obliquely  forward  at  each  end. 

In  the  male  the  propygidium,  pygidium,  the  middle  of  the  abdo- 
men, aiul  the  sutural  margins  of  the  elytra  (dilating  anteriorly 
to  the  shoulders)  are  covered  with  bright  orange-coloured  scales. 
These  are  entirely  absent  in  the  female,  which  has  the  middle  and 
sides  of  the  propygidium  and  pygidium,  in  addition  to  the  parts 
already  described,  decorated  with  grey  scales. 

It  is  a  large  species  and  very  elongate,  with  slender  legs.  The

the  hind  margin  is  rather  strongly  curved.  The  scutelhim  is 
very  long  and  narrow.  The  front  tibia  is  very  slender  and  armed 
with  five  teeth,  of  which  the  1st,  3rd  and  5th  are  sharp,  and  the 
2nd  and  4th  small  and  blunt,  the  interval  between  the  3rd  and  4th

233.  Charitovalgus  longulus. 

Valgus  longulus,  Gestro,*  Ann.  Mus.  Genova,  (2)  x,  1891,  p.  855. 

Dark  brown,  with  the  legs  and  a  round  prominence  near  each 
hind  angle  of  the  pronotum  deep  red ;  clothed  with  fine  scales, 
which  are  deep  chocolate-colour,  except  upon  the  legs,  at  the 
angles  of  the  pronotum,  the  front  margins  of  the  elytra,  and  the 
sides  of  the  propygidium,  pygidium,  sternum  and  abdomen,  where 
they  are  buft'-coloured.  There  is  a  fine  white  semicii'cular  line 
crossing  the  elytra  at  the  middle  and  curving  upwards  towards 
the  shoulders. 

The  sides  of  the  pronotum  are  almost  straight  and  gently  diverge 
from  the  front  to  the  base,  which  is  strongly  rounded.  The 
dorsal  carinae  are  sharp  and  nearly  parallel,  and  terminate  abruptly 
near  the  middle  of  the  pronotum.  There  is  a  pair  of  sharp 
tubercles  between  the  carinse  and  the  basal  margin,  and  a  shining 
red  area  extends  from  each  of  these  to  the  hind  angle.  The 
scutellum  is  rather  long  and  acute  at  the  apex.  The  elt/tra  are 
very  flat  above  and  straight  at  their  extremities.  The  front  tibia 
is  short  and  broad,  with  the  1st  and  3rd  teeth  sharp,  the  2nd  and 
5th  broader  and  blunter,  and  the  4th  obsolete.

Deep  chestnut-colour,  clothed  with  scales  varying  in  colour 
from  almost  white  to  ochre  and  from  that  to  deep  chocolate.  The 
medial  basal  part  of  the  prouotum,  the  scutellum,  and  the  middle 
of  each  elytron  are  dark,  and  the  elytra  are  decorated  with  whitish 
scales  along  the  anterior  margins,  the  sutui'e,  and  a  backwardly- 
curved  transverse  line  upon  the  inner  half  of  each  at  the  middle. 
The  prop3'gidium,  pygidium,  abdomen  and  legs  are  clothed  with 
pale  ochreous  scales. 

The  pronotum  is  about  as  long  as  it  is  broad,  with  the  sides 
serrated  and  not  strongly  curved,  and  the  base  regularly  rounded. 
The  dorsal  carintc  are  rather  far  apart  and  diverge  shghtly  behind, 
and  there  are  four  conical  elevations  placed  in  a  line  parallel  with 
the  posterior  margin.  The  scutellum  is  small.  The  elytra  are 
minutely  toothed  at  the  shoulders  and  their  lateral  costae  are 
rather  spinose  behind.  The  front  tibia  is  rather  short  and  broad, 
with  the  1st,  3rd  and  5th  teeth  strong  and  sharp,  the  liud  smaller 
and  the  4th  scarcely  traceable.     The  tarsi  are  rather  long. 

cJ .  The  hind  tarsi  are  nearly  three  times  the  length  of  the 
tibiae. 

2  .  The  hind  tarsi  are  more  than  twice  the  length  of  the  tibia?. 
The  caudal  spine  is  bent  downwards  at  the  apex  and  tridentate,

TBICHIUS.  249 


Division  III.— TRICHIINI. 

The  members  of  this  group  are  generally  characterised  by  a 
less  compact  build  and  a  softer  condition  of  the  integuments  than 
is  found  in  other  Cetonii>^^.  The  legs  are  generally  long  and 
slender  and  the  whole  body  is  capable  of  freer  movement.  The 
mouth  is  suctorial  and  its  various  parts  do  not  essentially  differ 
from  those  of  the  Cetoxiini.  The  mesosternal  epimera  do  not 
rise  into  the  angle  between  the  shoulders  of  the  elytra  and  the 
pronotum,  and  the  hinder  part  of  the  latter  is  not  closely  co- 
adapted  to  the  elytra.  The  front  of  the  elytra  and  scutellum  form 
a  ridge  against  which  the  hind  margin  of  the  pronotum  is 
brought  to  rest.  When  drawn  forward  the  thorax  is  thus  more 
freely  movable  than  in  the  more  typical  CETOisriiN^.  The  elytra 
cover  the  sides  of  the  abdomen  and  are  not  at  all  cut  away  behind 
the  shoulders  and  they  have  therefore  to  be  raised  in  the  usual 
manner  when  the  wings  are  used. 

The  larva  of  the  common  European  representative,  Trichius 
fasciatus,  L.,  is  closely  like  those  of  the  true  Cetoniini.  This 
genus  is  the  only  one  represented  in  our  region.

Type,  Trichius  fasciatus,  L.  (Europe). 

Range.  Europe,  Continental  Asia  and  Japan. 

Body  rather  loosely  articulated,  not  compact,  with  long  and 
slender  legs.  Eyes  large  and  prominent  and  clypeus  long, 
slightly  bilobed.  Antennae  rather  long.  Prothorax  narrow,  not 
emarginate  nor  distinctly  lobed  before  the  scutellum.  Scutellum 
very  short,  with  curvilinear  sides.  Elytra  broad,  not  reduced  at 
the  sides,  with  the  hind  margins  separately  rounded.  Meso- 
sternum  not  prominent  in  front.  Front  tibiae  bidentate.  Hind 
tibiae  truncate  at  the  end.  Mandible  feebly  chitinised,  with  the 
outer  lobe  long,  thin  and  straight.  Maxilla  long,  without  teeth, 
thickly  fringed  with  hairs.  Mentum  long,  deeply  notched  in 
front,  with  the  palpi  rather  short. 

J  .  The  abdomen  is  arched  beneath,  and  the  hind  tarsus  and  the 
club  of  the  antenna  are  generally  longer  than  in  the  female. 

2  .  There  is  a  strong  spinose  ridge  beyond  the  middle  of  the 
middle  tibia. 

The  form  and  pattern  are  very  subject  to  variation,  and  some- 
times strikingly  different  in  the  two  sexes,  but  there  is  no  distortion 
of  the  middle  tibiae  of  the  male  as  in  the  genus  Gnorimns. 

The  European  representatives  of  the  genus  live  during  the 
early  stages  in  decaying  tree-stumps.

Black,  with  the  clypeus,  prothorax,  scutelhim,  elytra,  a  broad 
line  along  the  middle  of  the  pygidium,  and  the  legs  deep  crimson 
in  the  6 ,  and  the  femora  and  tibicT3  only  in  the  ?  ;  decorated  \yith 
the  following  white  markings :— an  incomplete  narrow  margnial 
line  on  each  side  of  the  prothorax  (in  the  d  ),  ^  spot  on  each 
mesosternal  epimerou,  six  spots  at  the  median  part  of  each  elytron 
(viz.,  two  near  the  outer  margin,  two  towards  the  inner  margm, 
and  two  along  the  middle  line)  and  usually  one  adjoining  the 
scutellum  and  one  in  the  apical  angle  of  each  (at  least  in  the  6  ), 
and  an  elongate  patch  on  each  side  of  the  pygidium  (usually 
divided  in  the  $  ).  There  are  also  generally  patches,  in  the  6  at 
least,  on  the  metasternum,  the  front  and  hind  coxa?,  and  two  rows 
on  each  side  of  the  abdomen  beneath. 

It  is  a  small  species,  entirely  opaque  above  and  very  thinly 
clothed  with  yellow  seta?  beneath.  The  liead  and  ivynotum  are 
rugosely  punctured,  the  chjpeus  as  long  as  it  is  wide,  with  the  sides 
strongly  curved  and  the  front  margin  bilobed.  'I\\e  prothorax  is 
broader  than  it  is  long,  slightly  attenuated  in  front,  with  the 
margins  irregularly  rounded  and  a  broad  furrow  along  the  middle 
of  the  disc.  Th.e  scutellum  is  strongly  punctured,  with  a  smooth 
median  carina,  and  nearly  semicircular  in  shape.  Tlie  elytra  bear 
impressed  rows  of  annular  punctures,  the  pyrikUum  is  finely 
strigose,  the  metasternum  entirely  rugose  and  the  abdomen  coarsely 
punctured.  The  legs  are  very  slender  and  the  front  tibice 
bidentate. 

In  addition  to  the  different  colouring  described  above,  the  male 
has  the  prothorax  less  transverse  than  the  female,  the  hind  tarsi 
longer,  and  the  abdomen  rather  concave  beneath.  The  club  of

Black,  with  the  antennae,  legs,  clypeus,  prothorax  and  elytra 
more  or  less  testaceous  red.  The  pronotum  is  decorated  with  a 
white  marginal  line,  interrupted  in  the  middle,  and  (usually)  a 
small  discoidal  white  spot  on  each  side  ;  each  elytron  with  a  white 
spot  in  the  middle  and  another  placed  a  Httle  behind  and  outside 
of  the  first.     The  colouring  is  exceedingly  variable,  but  the  femora,

tibise  and  tarsal  joints  are  ringed  with  black  at  the  extremities; 
the  forehead  is  black  :  the  pronotuui  red,  with  a  large  black  patch 
on  each  side,  or  entirely  red  ;  and  the  elytra  black,  with  an  anterior 
and  posterior  red  mark  on  each,  or  red,  with  the  margins  and  a 
median  patch  npon  each  black. 

The  form  is  small  and  slender  and  the  legs  long.  The  head 
is  finely  punctured,  with  the  clypeus  about  as  long  as  it  is  broad 
and  gently  emarginate  in  front.  The  irroaotum  is  (coarsely  punc- 
tured, slightly  grooved  along  the  middle  and  subcircular  in  shape, 
with  the  sides  straight  and  convergent  in  front,  and  the  front 
angles  sharp.  The  scuteUwn  is  very  short,  nearly  semicircular 
and  slightly  punctured.  The  elytra  are  coarsely  punctate-striate  and 
the  jjygidiiua  is  very  sparsely  punctured.  The  front  tibire  are  bi- 
dentate,  and  the  aniennal  club  is  long  in  both  sexes,  very  long  in 
the  male. 

The  upper  surface  is  entirely  opaque  in  the  male,  but  the  pro- 
notum,  scutellum  and  elytra  are  shining  in  the  female.  The  pygi- 
dium  of  the  male  bears  a  large  white  patch  on  each  side  and  the 
greater  part  of  the  sternum  and  abdomen  is  also  white.  The 
prothorax  is  rather  more  elongate  in  the  same  sex,  the  hind  tarsi 
are  longer  and  the  abdomen  is  strongly  arched  beneath.

Deep  metallic  green,  more  or  less  coppery  on  the  head  and  lower 
surface  and  opaque  above,  with  the  antennae,  legs  and  a  broad  line 
extending  from  the  shoulder  to  the  apex  of  each  elytron  bright 
orange ;  decorated  with  pale  yellow  markings  consisting  of  a 
narrow  longitudinal  line  at  the  middle  of  the  pronotum,  and  a 
marginal  line  and  a  minute  median  spot  on  each  side,  the  scutellum, 
a  longitudinal  line  on  each  elytron  near  the  suture,  starting  from 
the  base  but  not  quite  reaching  the  posterior  edge,  a  basal,  an 
apical,  and  three  lateral  spots  upon  each,  and  large  patches  on  each 
side  of  the  pygidium,  sternum  and  abdomen. 

The  body  is  moderately  slender  and  the  legs  are  very  long,  the 
front  tibia  armed  \\'ith  two  teeth  at  the  extremity  and  slightly 
serrated  beyond  them.  The  club  of  the  antenna  is  shorter  than 
the  footstalk  in  both  sexes.  The  head  is  I'ugosely  punctui-ed,  and 
the  clypeus  a  little  longer  than  it  is  broad  and  not  very  deeply 
notched  at  the  front  margin.  The  jpronotum  is  strongly  punctured, 
lightly  grooved  along  the  middle  and  rather  broader  than  it  is  long, 
with  the  front  angles  acute,  the  hind  angles  very  bluntly  pro- 
minent and  the  sides  and  base  gently  curved.  The  scutellum  is 
shortly  triangular.  The  elytra  are  strongly  punctate-striate,  the 
pygidium  finely  rugose,  and  the  metasternum  and  abdomen  punc- 
tured and  clothed  with  a  short  yellow  pubescence. 

c?  .  The  antennae  and  legs  are  more  slender  than  those  of  the 
female,  the  prothorax  is  broader  at  the  base  and  the  abdomen  is 
strongly  arched.  The  vertex  of  the  head  and  the  pronotum  are 
generally  more  opaque,  and  there  are  often  additional  pale  mark- 
ings upon  the  vertex,  pronotum  and  elytra.

Deep  metallic  greeu,  thickly  clothed  beneath,  except  at  the 
middle  of  the  abdomen,  \vith  a  short  greyish-yellow  pubescence, 
which  also  forms  a  narrow  line  at  each  side  of  the  pronotum 
(continued  a  little  round  the  posterior  angles)  and  three  small 
patches  at  the  base  of  the  pygidium. 

It  is  a  very  large  species  and  rather  stoutly  built  and  convex. 
The  head  is  densely  and  rugosely  punctured  and,  together  with  the 
pronotum  and  the  external  margins  of  the  elytra,  bears  very 
minute  setae.  Tl\\eclypeus  is  about  as  long  as  it  is  broad  and  deeply 
incised  in  front.  The  pronotuin  is  strongly  punctured,  about  as 
long  as  it  is  broad,  much  narrowed  in  front  but  scarcely  at  all 
behind,  with  all  the  angles  sharp,  the  front  ones  acute  and  the 
posterior  ones  right  angles,  the  sides  sinuated  and  the  base  gently 
curved.  The  scxdellum  is  broad  and  bears  a  few  punctures.  The 
elytra  are  deeply  sulcate,  the  sulci  being  rugose  at  the  bottom,  and 
the  lateral  and  apical  margins  are  finely  rugose.  The  p>/g'uUum 
is  rather  feebly  rugulose.  The  mesostenmm  forms  a  short  com- 
pressed vertical  lamina  between  the  middle  coxae.  The  club  of 
the  anienna  is  short  in  both  sexes  and  the  leys  are  modei-ately, 
but  not  extremely,  slender. 

S  .  The  front  tibia  is  simple,  armed  only  with  a  blunt  apical 
prolongation,  and  the  abdomen  is  channelled  along  the  middle,  with 
a  median  line  of  pubescence. 

$  .  The  front  tibia  is  feebly  bidentate,  the  abdomen  is  convex

256  DYXASTIN-H;. 


Subfamily  DYNASTIN^. 

The  Subfamily  Dyxastix.e,  although  not  one  of  the  largest,  is 
one  of  the  best  known  groups  of  Lamellicokxia,  iucludiug  many 
of  the  largest  and  most  striking  of  the  beetles.  It  is  very 
scantily  represented  in  the  Oriental  Kegion  and  its  Indian  repre- 
sentatives number  only  forty-six  out  of  a  total  of  about  a  thousand 
described  species.  Although  closely  related  to  the  Cktoxiin'.i:,  one 
of  the  most  remarkable  for  brilliant  colouring  among  the  groups 
of  Coleoptera,  this  on  the  contrary  is  one  of  the  most  sombre. 
This,  as  would  be  supposed,  implies  a  notable  difference  of  habit,  for, 
Avhilst  the  foregoing  Subfamily  is  in  general  conspicuously  diurnal, 
the  Dyxastin.e  generally  remain  in  concealment  by  day  and  emerge 
at  night,  when  decorative  effects  could  have  no  signiticauce.  The 
majority  of  species  are  black,  and  almost  the  only  departure  from 
the  rule  occurs  when  by  some  deficiency  of  the  black  pigment  shades 
of  yello\\",  brown  or  red  are  produced.  Even  within  these  limits, 
nothing  in  the  nature  of  a  pattern  is  found  except  in  an  American 
genus,  Cyclocephala,  and  a  few  other  American  species.  These 
exceptional  members  of  the  group  are  found  to  have  exceptional 
habits,  being  entirely  diurnal  and  frequenting  flowers  like  many  of 
the  Cetoniin.x.  A  single  Indian  species,  Chalcosoma  atlas,  the 
largest  of  Indian  beetles  and  one  of  the  most  striking,  has  a  slight 
greenish  metallic  lustre  and  is  almost  unique  in  that  respect. 

The  group  is  chiefly  remarkable  as  that  in  which  sexual 
dimorphism  appears  in  some  of  its  most  striking  phases.  Horns  of 
relatively  enormous  size  occur,  chiefly  in  the  males,  upon  the  head 
audtliorax  ;  and  as  some  of  the  species  in  which  they  attain  their 
maximum  development  are  also  among  the  largest  existing  insects, 
they  have  naturally  always  attracted  quite  exceptional  attention. 


Strvdure. 

Practically  all  the  Dtnastix.e  are  winged,  and  in  flight  the 
wings  are  spread  in  the  usual  way,  so  that  the  structure  of  the 
elytra  and  the  correlated  parts  of  the  thorax  is  not  of  the  peculiar 
type  found  in  the  Cetoxiix-i:.  The  scutellum  is  always  exposed, 
small  and  bluntly  triangular,  and  the  elytra  completely  cover  the 
abdomen,  except  the  pygidium  and  generally  part  of  the  pro- 
pygidium.  The  latter  often  bears  a  vocal  apparatus,  consisting  of 
tine  transverse  ridges  capable  of  beiug  drawn  like  a  flle  across  the 
sharp  inturned  posterior  edge  of  the  elytra  by  the  movement  of 
the  abdomen.  The  ridges  are  sometimes  very  long  and  cover  the 
greater  part  of  the  segment,  which,  moreover,  may  be  considerably 


DYNASTIN^.  257 

enlarged  at  the  expense  of  the  pygidium,  as  in  the  genus  Dipelicus 
(see  fig.  76)  ;  in  another  group  {Heteronychus,  etc.)  the  ridges 
are  restricted  to  two  longitudinal  lines  near  the  middle  of  the  pro- 
pygidium.  Some  species,  which  do  not  possess  the  apparatus  in 
either  form,  nevertheless  produce  a  considerable  volume  of  sound 
by  movements  of  the  abdomen  similar  to  those  by  which  the 
stridulating  ridges  are  brought  into  opei'ation.  Air  is  apparently 
imprisoned  between  the  elytra  and  the  back  and  then  expelled 
with  some  force,  producing  a  hissing  sound.  In  the  large  and 
common  Xylotrupes  gideon  this  has  often  been  observed. 

The  occurrence  of  horns,  even  of  the  largest  size,  upon  the  head 
is  not  accompanied  by  a  corresponding  development  of  the  head 
itself,  which,  on  the  contrary,  is  relatively  smaller  than  in  the 
Cetoniin^.  The  clypeus  is  genei'ally  small  and  the  eyes  less 
prominent  than  in  the  previous  group,  being  divided  in  front 
by  a  ridge  which  forms  a  lateral  extension  of  the  clypeus.  The 
antennae  are  inserted  beneath  this  ridge  and  consist  of  ten 
joints,  of  which  three  form  the  club.  They  show  little  variation 
throughout  the  Subfamily,  nor  do  they  appreciably  differ  in  the 
two  sexes. 

The  mandibles  are  much  more  developed  than  in  the  Cetoniin^ 
and,  except  in  certain  forms  not  represented  within  the  Indian  area, 
are  always  in  part  visible  from  above  (i.  e.  produced  beyond  the 
margins  of  the  clypeus)  and  generally  notched  or  lobed  at  the 
outer  edge.  The  maxillae  are  generally  furnished  with  several  sharp 
strong  teeth  and  closely  fringed  with  stiff  hairs.  The  mentum 
and  ligula  are  fused  together  and  the  labrum  small,  membranous 
and  concealed. 

The  legs  are  inserted  in  a  rather  different  manner  to  that  found 
in  the  Cetoniin^.  The  front  coxae  are  more  deeply  imbedded  in 
the  thorax,  broad  and  transverse,  and  the  prosternum  forms  a 
process  behind  them  which  is  sometimes  free  and  columnar, 
sometimes  inclined  and  in  close  contact  with  the  coxae.  All  the 
coxae  ai-e  contiguous  in  the  middle,  so  that  the  mesosternum  is 
divided  from  the  metasternum  and  the  two  parts  do  not  produce 
in  the  middle  a  process  pointing  forward  as  in  most  CetoniintE  and 
many  Eutelin^  and  Melolonthin^.  The  legs  differ  considerably 
in  form.  Some  genera,  apparently  with  more  than  the  normal 
digging  powers,  have  them  extremely  short,  with  very  thick  and 
muscular  femora  and  tibiae,  the  latter  generally  trumpet-shaped 
and  their  wide  extremities  fringed  with  very  strong  spines,  and  the 
tarsi  tapering  and  very  slight  at  the  end.  The  rest  have  the  legs 
of  moderate  length,  and  the  tarsi  slender  and  uniform.  The  front 
tibia  has  always  three  stout  external  teeth  and  there  are  sometimes 
four  or  more,  in  which  last  case  smaller  teeth  appear  between  the 
three  primary  ones.  The  claws  are  always  simple,  symmetrical  and 
immovable,  except  upon  the  foi-e-feet  of  the  males  in  certain 
genera.

f^58  DTIfASTm^. 

Sexual  Dimorpliism. 

The  existence  of  horns  in  the  male,  which  in  the  previous  group 
is  of  exceptional  occurrence,  here  becomes  characteristic  and  in 
some  of  the  large  species  these  appendages  reach  a  size  unequalled 
in  any  other  insects.  They  usually  take  the  form  of  a  slender 
recurved  horn  upon  the  front  of  the  head,  sometimes  toothed  or 
bifurcated,  and  generally  represented  only  by  a  slight  tubercle  in 
the  female  ;  and  upon  the  pronotum  one,  two  or  more  processes 
directed  forwards  or  upwards,  and  often  rising  from  the  margin  of 
a  dorsal  cavity.  Such  a  cavity  may  be  present  without  any  pro- 
cesses and  it  may  exist  in  both  sexes  but  differ  in  shape,  as  in 
Eo^iihiJeurus  chlnensis.  In  the  very  largest  Dynastin.i,  in  \\-hich 
the  armature  of  the  male  attains  its  maximum  development,  there 
is  no  cavity,  but  the  pronotum  of  the  male  on  the  contrary  is  much 
elevated  or  humped.  In  the  smallest  forms  again,  as  in  the  genus 
Heteronyclms,  there  is  no  trace  of  such  a  sexual  armature. 

Although  generally  distinctive  of  the  male,  the  possession  of 
horns  is  not  invariably  so,  for  in  some  cases,  as  in  Oryctes 
rhinoceros,  the  well-known  Cocoanut  Beetle,  both  sexes  are  horned, 
but  some  distinctive  difference  of  form  is  always  discoverable  if  a 
sufficient  series  of  specimens  is  studied.  There  is  no  group  of 
insects  in  which  it  is  more  necessary  that  a  good  series  should  be 
examined  in  order  to  obtain  a  correct  idea  of  the  characteristic 
features  of  a  species.  In  the  early  days  of  Entomology,  when  only 
occasional  specimens  of  these  insects  had  yet  reached  Europe,  the 
variability  of  the  armature  and  even  its  sexual  character  was  un- 
recognised, and  almost  every  specimen  which  came  into  the  hands 
of  Linnaeus,  Fabricius  and  their  contemporaries  was  regarded  as 
the  representative  of  a  different  species  and  given  a  distinctive 
name.  It  has  not  been  considered  necessary  to  include  all  these 
names  in  the  present  work. 

Eemarkable  anomalies  occur  in  some  species  in  the  development 
of  the  horns,  as  seen  by  a  comparison  of  specimens  of  different 
size.  Horns  which  at  their  highest  development  are  slender  and 
simple  may  in  minor  examples  be  knobbed,  forked  or  toothed  in 
various  inexplicable  ways ;  and  it  was  almost  inevitable  that 
Chalcosoma  atJax,  for  instance,  when  known  only  from  a  few 
examples  brought  from  different  localities  should  be  considered 
to  form  several  distinct  species.  In  the  structure  of  the  legs 
there  are  two  opposite  tendencies  characterising  the  males  of 
different  groups  of  genera.  In  one,  containing  the  most  striking 
forms,  the  legs  become  elongated  to  a  greater  or  less  extent, 
while  in  another  the  front  legs,  and  especially  the  tarsi,  are  con- 
tracted, the  others  remaining  like  those  of  the  female.  In  the 
latter  case  the  anterior  claws  are  also  modified  in  the  males,  the 
inner  claw  benig  thickened  and  bent  and  frequently  giving  off  a 
broad  tooth.  This  formation  is  never  found  in  the  Cetomix.e  but 
in  some  degree  it  is  almost  general  in  the  Edtelixje.  In  other 
genera  of  Dynastin^,  which  occupy  an  intermediate  position,  the 


DTXASTIN^.  259 

legs  are  alike  in  the  two  sexes,  and  in  some  the  whole  aspect  is 
identical.  There  is  a  slight  difference,  however,  which  is  almost 
invariable  throughout  the  subfamilj  and  serves  to  determine  the 
sex  when  more  obvious  distinctions  are  wanting  or  doubtful.  The 
last  ventral  segment  is  more  or  less  angular  at  the  extremity  in 
the  female,  the  angle  coinciding  with  the  apex  of  the  last  dorsal 
segment  or  pygldium  :  while  in  the  male  this  segment  is  excised  at 
the  apex,  leaving  an  interval  between  it  and  the  apex  of  the 
pygidium  filled  by  a  membrane.  The  pygidiuni  itself  is  often 
extended  and  iuturned  in  correspondence  with  this  conformation 
in  the  male. 


Habits  and  Metamorphoses. 

The  Dtkastin^  being  practically  confined  to  the  warm  regions 
of  the  earth  and  almost  all  of  singularly  retiring  habits,  our 
knowledge  of  their  metamorphoses  and  modes  of  life  is  as  yet 
exceedingly  scanty.  With  the  exception  of  the  flower-haunting 
Cyclocephalini  of  Tropical  America,  they  appear  to  be  practically 
all  nocturnal  or  crepuscular,  lying  hidden  by  day  beneath  the 
ground  or  in  dark  recesses.  For  this  reason,  combined  with  the 
sombre  and  inconspicuous  colouring  which  is  the  usual  accompani- 
ment of  such  a  mode  of  life,  they  are  not  easily  found,  although 
generally  abundant,  and  in  very  few  cases  have  their  early  stages 
been  traced.  The  only  genus  in  which  anything  approaching 
complete  information  is  available  is  Orijctes  (the  Ehinoceros 
beetles),  of  which  not  only  are  the  species  exceedingly  abundant, 
but  one  of  them  (Oryctes  yiasicornis,  which  reaches  the  north- 
western part  of  the  Indian  region)  is  one  of  the  largest  of  the 
insects  inhabiting  European  countries.  This  beetle  has  been  the 
subject  of  valuable  anatomical  I'esearches,  some  of  which  have  been 
already  referred  to. 

An  interesting  fact  observed  in  different  genera  of  Dynastin^, 
and  in  different  parts  of  the  world,  is  the  considerable  growth 
which  takes  place  in  the  egg  between  the  times  of  deposition  and 
hatching.  Like  those  of  other  Lamellicornia,  the  eggs  are 
spherical,  whitish  and  moderately  smooth. 

The  larvae,  as  far  as  they  are  known,  do  not  differ  in  any  marked 
degree  from  those  of  the  Cetoniin.^  and  allied  subfamilies.  They 
are  rather  stout-bodied,  clothed  with  stiff  erect  hairs,  the  head  not 
very  large,  without  eyes,  the  mandibles  strong,  the  maxillae  single- 
lobed,  and  the  legs  well  and  equally  developed,  but  not  long.  Like 
the  Cetoniiis"^  also,  they  feed  during  this  stage  upon  decaying 
vegetable  matter,  and  sometimes  upon  living  roots  or  woody 
tissues.  The  food  of  the  adult  beetles  is  uncertain,  but  it  probably 
consists  chiefly  of  sweet  or  resinous  vegetable  exudations. 

An  account  recently  published  of  the  habits  of  a  species  found 
in  the  Southern  States  of  North  America  is  interesting  as  showing 
that  in  this  group,  as  in  the  Geoieupin.e,  Copein.e  and  other

Lamellicorn  subfamilies,  the  male  and  female  sometimes  collaborate 
in  the  construction  and  provisioning  of  a  nest  for  their  young.  In 
the  'Entomological  News,'  1908,  p.  286,  Mr.  A.  "H.  Manee 
describes  his  observations  in  North  Carolina  of  Straiegus  antceus, 
one  of  the  species  in  which  the  male  bears  strong  horns  upon  the 
thorax,  surrounding  a  deep  cavity.  The  beetles  were  found 
■working  in  pairs  in  the  neighbourhood  of  fallen  oak-leaves 
accumulated  in  hollows  by  the  wind.  A  shaft  an  inch  in  diameter 
was  first  excavated  by  them  vertically  in  the  ground  to  a  depth  of 
six  or  eight  inches,  the  dug  out  earth  forming  a  mound  at  the  top. 
From  the  foot  of  the  shaft  a  horizontal  chamber  of  rather  larger 
diameter  is  driven  from  one  to  five  inches  and  this  is  packed  with 
dead  leaves  reduced  to  a  fragmentary  state,  and  a  single  egg  is 
placed  in  the  middle  of  the  mass.  Sometimes  two,  and  rarely 
three,  such  horizontal  galleries  were  found,  each  containing  a 
sin"-le  egg.  The  egg  is  white  and  at  first  three  thirty-seconds  of 
an  inch  in  length  and  oblong,  but  in  three  or  four  days  it  has 
swollen  to  a  globular  shape  and  is  an  eighth  of  an  inch  in  diameter. 
Mr.  Manee  believes  that,  having  devoured  the  leaves  stored  up  by 
the  parent-beetles,  the  grubs  feed  upon  oak-roots. 

Various  DtnastiNjE  are  injurious  to  pasture-land  by  feeding 
upon  the  roots  of  grasses,  and  several  species  of  the  Heteronycliiis- 
group  have  been  found  to  destroy  the  roots  of  the  sugar-cane. 
The  common  Indian  Phyllognathus  dionysius  has  been  found  by 
Mr.  H.  Maxwell  Lefroy  to  feed  upon  the  roots  of  rice.  The 
development  is  exceedingly  rapid,  the  larval  stage  lasting  only  three 
months,  a  short  duration  which  lias  probably  been  brought  about 
as  an  adaptation  to  the  short  life  of  the  rice  crop  and  the 
alternating  periods  of  fertility  and  aridity  of  the  hot  plains  in 
which  it  is  cultivated. 

Oryctes  rhinoceros  is  a  serious  pest  in  cocoanut  plantations, 
destroying  the  fibrous  tissues  at  the  base  of  the  leaves  and 
admitting  the  rain  and  starting  decay  in  the  growing  tops  of  the 
palms.  Tliis  species  has  been  carefully  studied  by  Mr.  C.  S. 
Banks  and  described  in  the  Philippine  Journal  of  Science  for 
1906.  It  is  not  dependent  upon  living  food,  however,  being  also 
found  in  vegetable  debris,  and  even  flourishing  in  ordinary  soil 
containing  only  an  average  proportion  of  organic  matter.  Oryctes 
nasicor7iis  is  constantly  found  in  the  refuse-heaps  of  tanneries, 
where  the  larvte  feed  upon  the  decomposed  bark.  It  also  occurs 
in  Southern  Europe  in  garden  rubbish.

fine  irregular  puncturation.  The  elytra  have  a  very  fine  and  close,

moderately  strongly  and  closely  punctured,  becoming  rugose  at 
the  sides,  and  its  ventral  portion  is  smooth  and  shining.  The 
abdomen  is  shining  beneath  in  the  middle  and  irregularly  rugose 
at  the  sides.

points  which  curve  backwards.  The  basal  part  of  the  horn  is 
laterally  compressed  and  almost  cai'inate  above,  ending  in  a  strong 
compressed  tooth,  beyond  which  the  horn  becomes  depressed.  The 
pronotum  is  drawn  out  into  a  cone  directed  obliquely  forward  and 
produced  at  the  apex  into  a  gently  curved  horn  bifid  at  the 
extremity,  with  the  points  directed  a  little  downwards.  The  sides 
of  the  horn  are  carinate  on  the  basal  part  of  the  lower  surface. 
In  fully  developed  specimens  the  thoracic  horn  reaches  beyond

the  cephalic  horn  and,  measured  from  the  tips  to  the  base  of  the 
thorax,  considerably  exceeds  the  elytra  in  length.  The  inner  edge 
of  the  front  tibia  is  gently  bisinuate  and  the  outer  edge  armed 
with  three  very  sharp  slender  teeth,  of  which  the  two  uppermost 
are  rather  distant. 

In  males  of  minor  development  (var.  oromedon,  F.)  the  tooth  at 
the  upper  edge  of  the  cephalic  horn  disappears  and  the  thoracic 
horn  does  not  extend  as  far  as  that  of  the  head  and  is  very  feebly 
bifurcated. 

In  the  smallest  specimens  the  cephalic  horn  is  extremely  short 
but  distinctly  bifid  and  the  thoracic  horn  vanishes  completely, 
being  represented  only  by  a  slight  eminence.

surface  is  much  more  rugose.  The  head  is  very  rugose,  the 
pronotum  coarsely  punctured,  the  punctures  coalescing  at  the  front 
and  sides,  the  scutellum  thinly,  and  the  elytra  closely  and 
irregularly,  punctured.  The  pygidium  is  finely  rugose  and  the 
abdomen  irregularly  punctured  beneath.

Thomson's  types  are  in  M.  Bene  Oberthiir's  collection  :  the 
location  of  the  older  types  is  uncertain. 

Males  vary  to  a  remarkable  degree,  not  only  in  size  and  degree 
of  development  of  the  horns,  but  also  in  the  texture  and  fine 
sculpture  of  the  upper  surface.  Many  so-called  species  have  been 
based  upon  the  different  phases  of  this  sex,  but  none  of  them 
appear  to  have  at  present  justified  themselves  by  sufficient  evidence 
of  constancy  or  even  local  distribution. 

This  is  an  extremely  abundant  insect  throughout  the  East  and 
is  frequently  attracted  to  houses  by  light.  It  is  found  in  all  its 
stages  in  manure  heaps  and  accumulated  vegetable  debris.  The 
larvae  are  also  reported  to  injure  the  roots  of  cane-cuttings  in 
sugar  plantations,  and  the  adult  beetles  are  fond  of  the  exudation 
from  damaged  canes  and  are  said  even  to  make  their  way  into 
them. 

Although  not  provided  with  the  beautiful  stridulating  structure 
found  upon  the  upper  surface  of  the  abdomen  in  related  genera 
which  will  be  presently  described,  this  insect  is  able  to  produce  a 
loud  hissing  sound  by  some  means  which  has  not  been  investigated. 
It  is  perhaps  caused  by  the  compression  and  expulsion  of  air  held 
between  the  abdomen  and  elytra,  but  careful  observation  should 
.soon  reveal  the  source  of  the  sound.  That  it  is  used  as  a  means 
of  defence  is  shown  by  the  following  description  from  Lieut. -Col. 
Cunningham's  "  Plagues  and  Pleasures  of  Life  in  Bengal."     The

identity  of  the  species  referred  to  is  established  by  the  curiously 
coloured  but  sufficiently  accurate  figure :— "  One  of  the  most 
amusing  visitors  is  a  great  horned  beetle  who  possesses  a  most 
startling  power  of  stridulatiou.  When  one  of  them  comes  in  and 
falls  to  the  floor  he  walks  quietly  and  sedately  about  so  long  as  he  is 
left  to  his  own  devices  ;  but  whenever  he  is  in  any  way  alarmed  or 
interfered  with  he  suddenly  sits  up  on  his  hind  legs  and,  whilst 
brandishing  his  jagged  and  hooked  fore-paws  aloft,  emits  a  sound 
Ike  that  of  a  miniature  engine  blowing  off  steam.  This  per- 
formance is  seemingly  as  alarming  to  dogs  as  it  is  to  human  beings 
who  are  unprepared  for  its  occurrence.  One  hot  still  October 
night,  when  a  friend  and  I  were  quietly  seated  at  dinner,  one  of 
these  beetles  flew  into  the  room  and  in  due  course  fell  down  with 
a  sounding  flop  on  to  the  matting  of  the  floor.  A  long-haired 
Scottish  terrier,  who  was  always  on  the  outlook  for  shikar  of  any 
sort,  was  present  and  at  once  on  the  spot  to  inquire  into  the 
cause  of  the  disturbance.  The  intruder  at  first  lured  her  on  to 
close  investigation  by  minatory  gesticulations  and  then  drove  her 
wild  with  terror  by  stridulating  loudly  and  fastening  on  to  the 
hair  of  her  muzzle.  The  result. was  wild  panic  and  immediate 
flight,  in  the  course  of  which  she  rushed  violently  under  the  side- 
board, where  a  number  of  bottles  of  soda-water  were  lying  and 
completed  her  discomfiture  by  bursting  with  a  series  of  loud 
reports."

d  .  Very  massive  and  exceedingly  smooth  and  brilliant  above, 
with  long  and  slender  legs.  The  clypeus  is  strongly  bidentate  and 
the  ridges  in  front  of  the  eyes  are  large  and  prominent.  The  head

and  more  or  less  compressed  behind.  At  its  full  development  it  is 
longer  than  the  head  and  prothorax  together,  and  rather  sharply 
curved  near  the  middle.  The  posterior  edge  is  generally  provided 
with  a  laminar  projection  on  each  side  before  the  apex,  but  these 
may  be  absent  or  represented  by  a  fine  serration.  There  is  some-

sharp  horn  in  the  middle  of  the  anterior  margin,  greatly  elevated 
above  and  produced  at  the  sides  into  a  pair  of  slender,  acute,  nearly 
horizontal  horns  of  vcny  variable  curvature,  but  in  large  specimens 
enclosing  three-fourths  of  a  circle.  The  pronotum  is  considerably 
narrower  behind  than  the  elytra  and  is  sometimes  strongly  punc- 
tured at  the  sides,  but  the  punctures  may  become  partly  or  wholly 
obliterated.  The  scutellum  is  broad  and  irregularly  punctured  or 
smooth.  The  elytra  are  devoid  of  punctures  and  very  glossy. 
The  2'ro2J?/(/u/iM?u  is  closely  punctured  and  the  jn/( /id ium  and  the 
sides  of  the  metastemum  and  abdomen  are  finely  granulated  and 
clothed  with  miinite  erect  setic.  All  the  tarsi  are  elongate  but 
especially  the  front  ones ;  the  front  tibia  is  slender,  the  two 
uppermost  external  teeth  rather  far  apart  and  the  lower  face  armed 
with  a  row  of  short  perpendicular  teeth  ;  the  front  femora  have 
each  a  small  anterior  tooth. 

In  males  of  minor  development  (var.  Icirbyi)  the  cephalic 
horn  is  shortened  in  its  apical  part  and  the  subapical  lamina? 
become  more  prominent  antl  divergent,  forming  with  the  apex  a

and  are  generally  more  parallel,  disappearing  entirely  in  the  most 
dwarfed  specimens.

surface  is  not  at  all  shining.  The  head  and  pronotum  are  densely 
granulated  and  entirely  devoid  of  armature,  the  latter  very  convex, 
Avith  the  sides  regularly  curved  and  narrowed  to  the  front  angles. 
The  scutellum  is  shining  and  slightly  punctured,  and  the  elytra  are 
dull,  coriaceous,  clothed  with  minute,  reddish,  erect  setae,  which 
are  distributed  in  small  tufts  at  the  middle  of  the  back  and 
unifoi-mly  elsewhere,  and  the  pj/gidium  and  the  sides  of  the  meta- 
sternum  and  abdomen  are  clothed  with  similar  uniformly  distributed 
setae.     The  legs  are  shorter  and  of  normal  form.

and  very  convex  and  the  sides  of  the  body  are  clothed  beneath

Var.  cantori,  Hope.  The  entire  upper  surface  is  black,  except  a 
broad  reddish  yellow  band  at  the  outer  margins  of  the  elytra. 

Var.  niger,  nov.  The  whole  upper  surface  is  black, 
c? .  The  head  bears  a  moderately  long  horn,  which  is  strongly 
flattened  laterally  and  sharply  recurved.  It  is  quite  simple,  rather 
sharp  at  the  tip  and  slightly  rugose  at  its  basal  part.  The  pronotum 
is  extremely  smooth  and  shining,  with  a  few  minute  scattered 
punctures,  which  are  most  evident  near  the  posterior  angles.  It 
is  about  as  loug  as  it  is  wide,  with  the  sides  approximately  parallel 
from  the  posterior  angles  to  the  middle  and  strongly  tapering  from 
that  point,  the  anterior  angles  being  acutely  produced.  A  little 
behind  each  anterior  angle  arises  a  short  horizontal  horn  directed 
forward,  with  a  slight  outward  curve,  and  rather  sharply  pointed. 
The  posterior  dorsal  region  of  the  thorax  is  humped  and  gives  rise 
to  a  pair  of  siuiilar  but  rather  longer  and  nearly  vertical  horns 
curving  forward  at  the  tips.  The  scuteUmn  is  rugosely  punctured 
and  the  elytra  are  smooth  and  shining,  with  very  minute  scattered 
punctures  which  are  most  apparent  near  the  suture,  where  there 
is  a  line  of  larger  impressed  punctures  on  each  side.  The pygidium 
is  semi-opaque,  with  a  very  few  minute  punctures  and  a  finely 
rugose  area  in  each  lateral  angle,  and  the  apical  part  is  inturned. 
The  front  tibia  is  rather  slender,  the  three  teeth  are  long  and 
sharp,  and  the  lower  surface  has  a  series  of  tubercles  along  the 
middle.     All  the  tarsi  are  long  and  the  claw-joint  is  very  long. 

In  males  of  poor  development  the  cephalic  and  posterior 
thoracic  horns  become  reduced,  and  in  those  of  very  small  size 
(var.  cMldreni)  the  latter  completely  disappear.  The  lateral 
processes  of  the  thorax  are  fairly  constant  in  size. 

5  .  The  whole  surface  is  more  rugose  and  opaque,  the  head  and 
pronotum  are  coarsely  rugose  and  the  elytra  thinly  clothed  with 
tawny  setae,  the  sutural  edges  being  a  little  elevated  and  more 
shining.  The  pygidium  and  the  greater  part  of  the  loiuer  surface 
are  similarly  clothed.  The  cephalic  and  thoracic  armature  is 
entirely  absent.  The  legs  are  shorter  and  the  tarsi  considerably 
so.  The  colour  of  the  elytra  is  more  reddish  in  the  typical 
phase.

Herr  Nonfried  gives  Kashmir  as  the  locality  of  his  supposed

Eupatorus  gracilicoruis,  Arrow,*   Trans.  Ent.  Soc.  Lond,  1008, 
p.  351. 

Black,  with  the  elytra  straw-coloured  except  at  the  sutural  and 
extreme  outer  margins,  which  are  dark.  The  form  and  colouring 
are  almost  those  of  E.  hardwicl:ei ,  but  the  body  is  rather  more 
elongate  and  the  elytra  are  normally  lighter  in  colour  and  without 
a  paler  border. 

S  .  The  armature  is  similar  to  that  of  E.  Jiarchvickei,  but  all  the 
horns  are  more  slender,  that  of  the  head  in  the  largest  specimens 
reaching  a  length  of  40  mm.  The  anterior  thoracic  horns  are 
much  longer,  being  fully  as  long  as  the  posterior  pair,  strongly 
curved,  and  arising  farther  back  than  in  the  other  species,  giving 
the  prothorax  the  appearance  of  being  more  produced  in  front. 

2  •  This  is  extremely  like  that  of  the  older  species,  but  besides 
the  greater  elongation  and  paler  elytra,  the  latter  are  minutely 
pubescent  only  at  the  posterior  part  and  the  pronotum  is  more 
strongly  sculptured  and  closely  rugose  at  the  sides. 

Length  48-70  mm. ;  breadth  25-35  mm.

The  curvature  and  direction  of  the  horns  of  the  male  vary 
very  much.  The  ceplialic  horn  is  sometimes  very  strongly  and 
sometimes  only  slightly  curved  backwards,  and  the  anterior 
thoracic  horns  generally  diverge  considerably,  but  may  slightly 
converge.  In  small  specimens  the  dorsal  horns  may  completely 
disappear. 

I  have  seen  a  considerable  number  of  examples,  most  of  them 
males.

The  colovir  is  a  very  dark  chestnut,  approaching  black,  and  the 
form  convex  and  moderately  elongate.  The  upper  surface  is 
coriaceous  and  scarcely  shining,  the  scutellum  and  elytra  quite 
opaque,  and  the  pygidium  and  propygidium  finely  rugose  and 
minutely  setose.  The  lower  surface  is  very  scantily  furnished 
with  tawny  hairs. 

cJ .  The  head  is  bidentate  in  front  and  bears  a  long  slender  and 
sharply-pointed  horn,  strongly  curving  backwards  in  the  basal  half 
and  afterwards  almost  straight.  The  prothorax  is  about  as  long 
as  it  is  broad,  with  the  sides  nearly  parallel  behind  and  strongly 
tapering  in  front,  the  margins  produced  into  a  sharp  point  on  each 
side  just  behind  the  front  angle  and  the  dorsal  i)art  bearing  a  pair

that  of  the  type  specimen,  but  the  cephalic  horn  is  only  a  third  of 
the  length  and  bifurcated  at  the  end  and  the  thoracic  horns  are 
represented  by  a  pair  of  nodular  processes  occupying  the  same 
position,  but  showing  no  indication  of  the  very  peculiar  form 
assumed  in  their  fuller  development.

scattered  punctures  above  and  scanty  reddish  hairs  upon  the 
sternum,  sides  of  the  abdomen  and  legs. 

S  .  The  body  is  very  robust  and  convex.  The  head  is  triangular 
and  sparingly  punctured  and  carries  a  long  strongly  recurved  horn, 
the  posterior  face  of  which  is  flattened  and  slightly  excavated. 
T\\e  pronotum  is  minutely  aud  sparsely  punctured,  strongly  curved 
at  the  sides,  with  the  front  angles  promiuent  and  acute.  The 
])rothorax,  except  at  the  posterior  and  lateral  bordei's,  is  retuse, 
nearly  flat,  and  very  shining,  with  some  large  punctures  before 
and  behind  the  posterior  margin  of  the  flattened  part.  This 
margin  is  slightly  interrupted  and  depressed  in  the  middle,  and 
elevated  at  each  side  into  a  more  or  less  sharp  tooth.  The  scutellum 
is  rugose,  short  and  very  bluntly  augulated.  The  eh/ira  have  a 
minute  scattered  puncturatiou  and  a  single  line  of  larger  punctures

The  male  has  the  appearance  of  a  stout  and  broad  Oryctes,  while 
the  female  greatly  resembles  that  of  a  Trichogomphus,  but  the 
structure  of  the  hind  tarsi,  the  maxillae,  the  horn  of  the  male,  etc., 
show  it  to  have  a  truer  relationship  with  the  Chalcosoma  group, 
although  the  absence  of  any  elongation  of  the  legs  of  the  male 
forms  an  important  distinction  from  Chalcosoma,  Eupatorus,  etc.

terminating  in  a  broad  lobe,  not  tootlied  ;  palpus  long.  Mentum 
short  and  tapering  ;  palpus  very  short.  Prothorax  with  the  front 
angles  acute  and  the  hind  angles  rounded.  Prosternal  process 
flattened,  not  erect,  tufted  at  the  end.  Propygidium  enlarged  at 
the  expense  of  the  pygidium,  and  its  entire  surface,  except  the 
lateral  angles,  covered  with  microscopic  regular  transverse  stridu- 
lating  ridges.  Pygidium  inturned  beneath  and  very  prominent 
behind.  Legs  rather  short  and  stout,  the  front  tibia  armed  with 
three  or  four  strong  teeth,  and  the  middle  and  hind  tibiae  digitated 
at  the  end ;  tarsi  of  moderate  length,  the  basal  joint  in  the  four 
posterior  legs  distinctly  triangular. 

cJ  .  The  cephalic  horn  is  generally  longer  than  that  of  the  female 
and  the  pygidium  is  smooth  and  convex. 

9 .  The  pygidium  is  more  or  less  conical. 

This  is  the  first  genus  so  far  dealt  with  in  which  a  stridulating 
organ  occurs.  The  delicate  ridges  occupy  a  considerable  area, 
])ractically  covering  the  penultimate  dorsal  segment,  and  the 
vibrations  are  produced  by  movements  of  the  abdomen  causing  a 
sharp  edge  at  the  end  of  each  elytron  to  be  drawn  across  the  ridges. 
Darwin,  in  the  '  Descent  of  Man,'  called  attention  to  a  difference 
of  structure  according  to  sex  in  the  stridulating  apparatus  of 
Oryctes,  resulting  as  he  supposed  in  its  greater  effectiveness  in 
the  male.  It  is  true,  as  he  noticed,  that  the  microscopic  hairs 
scattered  over  the  propygidium  are  more  numerous  and  con- 
spicuous in  the  female,  but  the  effective  part  of  the  striated 
surface  appears  to  be  only  a  small  area  upon  each  side  which  is 
bare  in  both  sexes,  and  in  the  sculpturing  of  these  areas  I  have 
not  been  able  to  detect  any  such  difference  as  described  by 
Darwin.  It  is  strange  that,  although  two  of  the  species  here 
described  are  extremely  common  and  well-known,  I  have  failed  to 
obtain  any  account  of  the  sound  produced  by  them.

coalescing  punctures  adjoining  the  suture  and  slight  traces  of  other 
double  sei'ies.  The  stridulating  ridges  of  the  projiygidium  are 
exceedingly  fine.  The  front  tibia  is  armed  with  three  external 
teeth  and  without  any  tooth  ou  the  lower  surface ;  the  middle 
tibiae  are  not  much  shorter  than  the  hind  ones,  and  each  of  the 
four  posterior  tibias  is  armed  at  the  extremity  with  two  not  very 
acute  teeth. 

cJ.  There  is  a  strongly  recurved,  rather  compressed  horn  ou  the 
head,  rugose  at  the  sides  and  punctured  in  front,  and  the  prothorax 
is  strongly  angulated  at  the  sides,  which  are  produced  forward 
forming  acute  angles  in  front.  The  disc  is  broadly  elevated 
behind,  forming  a  three-toothed  transverse  carina,  and  cut  away 
from  the  carina  to  the  front  margin.  The  posterior  part  is  finely 
punctured,  the  anterior  declivity  smooth  and  scarcely  punctured, 
and  the  sides,  except  in  the  posterior  part,  coarsely  rugose.  The 
pygidium  is  very  convex  and  quite  smooth  and  shining,  except  in  its 
lateral  angles,  where  it  is  very  finely  rugose. 

2  ,  The  head  is  entirely  rugose  and  armed  only  with  a  very 
short  conical  horn  directed  backwards.  The  prothorax  is  rounded 
at  the  sides,  the  front  angles  are  not  prominent,  there  is  a  slight, 
transversely  oval  excavation  reaching  from  the  front  margin  to 
near  the  middle  and  the  surface  is  entirely  rugose,  except  near  the 
bind  margin,  where  it  is  punctured.  The  propygidium  bears  a 
microscopically  fine  pubescence  and  the  stridulating  ridges  are 
slightly  coarser  than  in  the  male.  The  pygidium  is  punctured 
and  rather  thinly  pubesceut,  with  a  transverse  carina  which  is 
angulated  in  the  middle.

representative  of  the  TN^estern  and  Central  European  Onjctes 
nasicornis  ;  but,  altliough  there  is  a  tendency  for  one  or  other  of 
the  forms  to  preponderate  in  the  different  regions,  they  also  occur 
together,  and  when  a  large  series  is  studied  it  becomes  impossible 
to  divide  them  sharply. 

0.  nasicornis  is  the  largest  and  most  common  of  the  two  or  three 
insects  Avhich  alone  represent  the  essentially  tropical  subfamily 
DiNASTiNiE  in  Europe.  It  is  found  in  old  decayed  trunks  of  oak, 
olive,  chestnut  and  other  trees,  in  accumulations  of  vegetable 
debris  in  gardens,  etc.,  and  most  commonly  of  all  in  the  refuse 
heaps  of  tanneries,  from  whicli,  in  the  countries  it  inhabits,  it  is 
said  to  be  rarely  absent.  Westwood  states  that  the  larval  period 
lasts  four  or  five  years,  but  probably  this  is  only  when  it  is 
retarded  by  unfavourable  circumstances.  The  beetles  conceal 
themselves  during  the  day  and  fly  at  dusk,  appearing  in  Southern 
Europe  about  July.  Xambeu  (Le  IS'aturaliste,  1902,  p.  102) 
gives  the  following  particulars  : — The  eggs  when  laid  are  coated 
with  a  glutinous  substance  which  causes  the  surrounding  earthy 
particles  to  adhere  to  and  conceal  them,  an  obvious  protection 
against  hungry  foragers.  Twelve  or  fifteen  eggs  are  deposited 
not  far  apart  within  the  tree  or  refuse-heap  and  hatch  in  fifteen 
to  twenty  days.  The  larva  feeds  during  the  autumn  and  winter 
and  pupates  in  May.  According  to  M.  Fabre,  this  larva  is  the 
natural  prey  of  the  great  parasitic  Wasp,  Scolia  hortorum,  the 
female  of  which  seeks  it  out  in  its  retreat  and,  having  paralysed 
it  by  stinging  it  in  the  ventral  ganglion-mass,  deposits  an  egg 
beside  the  puncture.  The  Scolia  grub  rapidly  devours  the  whole 
interior  of  its  immobile  victim,  leaving  only  an  empty  skin  beside 
which  it  forms  its  own  cocoon.

Dark  chestnut-red,  with  the  pygidium,  femora  and  lower  surface 
lighter  and  the  head  and  pronotum  sometimes  darker. 

It  is  a  small  species,  elongate,  cylindrical,  smooth  and  shining 
above,  and  clothed  with  erect  tawny  setae  beneath.  The  clypeus 
has  two  sharp  divergent  teeth  in  front.  T\\q  pronotum  is  strongly 
rounded  at  the  sides,  with  the  hind  angles  obliterated.  It  is  ex- 
cavated and  rugose  in  front  and  smooth  behind.  The  scutellvm  is 
irregularly  punctured  and  the  elytra  are  finely  and  irregularly 
punctured,  some  of  the  punctures  forming  indistinct  double  rows. 
The  propyfjidium  is  finely  transversely  striated.  The  front  tibia 
is  armed  with  three  strong  teeth  and  a  blunt  uppermost  one,  and 
the  middle  and  hind  tibiae  are  strongly  and  sharply  digitated  at 
the  end. 

S .  The  head  bears  a  strongly  curved,  not  very  long,  horn  and 
is  rugose  at  the  sides.     The  pronotum  has  a  broad,  oval,  rugose

excavation  extending  from  the  front  to  about  the  middle,  the  hind 
margin  being  very  feebly  produced  forwards  into  a  slight  bifid 
process.  The  posterior  half  of  the  pronotum  is  smooth  and 
shining,  with  only  a  few  minute  punctures ;  the  front  angles  are 
depressed  and  rugose,  and  there  is  a  narrow  rugose  area  near  the 
median  excavation  on  each  side.  The  pygidium  is  bare,  smooth 
and  shining  in  the  middle,  where  there  are  only  minute  punctures, 
and  coriaceous  at  the  sides. 

5  .  T!ie  head  is  entirely  rugose  and  armed  with  a  very  short 
horn.  The  pronotum  has  an  anterior  rugose  depression  which 
does  not  reach  the  middle,  aud  the  posterior  margin  of  this  is 
feebly  produced  forward  into  a  blunt  point.  There  is  a  small 
punctured  area  just  behind  this  point  and  a  large  rugose  depression 
on  each  side.  The  pygidium  is  pointed  and  clothed  Avith  rather 
long  tawny  hairs.

This  is  probably  the  Oryctes  siaaicus  of  Walker,  presumably 
brought  from  the  Sinai  Peninsula,  but  the  type  of  that,  together 
with  the  numerous  other  Coleoptera  described  by  Walker  in  the 
same  paper,  no  longer  exist,  and  as  few  of  the  species  will  ever 
be  determined  with  any  degree  of  certainty  from  the  descriptions 
I  consider  it  best  to  treat  the  names  as,  like  the  types,  non- 
existent. The  collection  was  housed  in  the  School  of  Medicine  at 
Cairo,  but  the  late  Director  of  that  Institution,  Dr.  Innes,  informs 
me  that,  through  neglect,  the  insects  had  entirely  disappeared  more 
than  twenty  years  ago,  and  only  the  labels  remain. 


250.  Oryctes  nudicauda,  sp.  n. 

Deep  chestnut-colour,  with  the  lower  surface  reddish,  clothed 
Avith  tawny  hairs.  The  form  is  narrowly  cylindrical  and  the 
general  structure  that  of  Oryctes  rhinoceros,  L.  The  clypeus  is 
sharply  cleft,  the  points  not  strongly  diverging  and  the  horn  is 
rugosely  punctured,  except  at  the  base  behind.  The  pronotum  is 
distinctly  transverse,  strongly  margined  all  round,  with  the  front 
angles  acute,  the  hind  angles  almost  obliterated  and  the  sides 
strongly  bisinuated.  There  is  a  transversely  oval  rugose  excavation 
extending  from  the  front  margin  to  the  middle  or  beyond  it  and 
bounded  by  a  smooth  carina  with  a  slight  projection  behind. 
There  is  an  elongate  depression  outside  the  carina  on  each  side, 
and  another  in  each  front  angle.  All  these  depressions  are  rugose, 
and  the  remaining  surface  is  smooth,  shining  and  minutely 
punctured.  The  scutellum  is  rugose,  with  a  smooth  outer  margin, 
and  the  elytra  are  moderately  punctured,  the  punctures  being 
annular  and  some  of  them  forming  inconspicuous  double  rows  ; 
the  apical  margins  are  densely  punctured.  The  propygidium  is 
scarcely  produced  and  the  stridulatory  ridges  are  not  very  fine.

The  i^ygidium  is  smooth,  rounded  and  very  finely  rugose  in  both 
sexes.  The  front  tibia  is  armed  with  four  teeth,  the  uppermost  one 
small,  and  there  is  only  a  ve.->tige  of  a  tooth  upon  the  lower  face. 
The  middle  and  hind  tibiae  are  very  acutely  digitated. 

S  •  The  cephalic  horn  is  longer  than  that  of  the  female  and 
the  posterior  margin  of  the  thoracic  cavity  forms,  in  the  middle, 
part  of  a  very  broad  trisinuate  projection.  The  pygidium  is  very 
convex  and  quite  hairless. 

$  .  The  lateral  rugose  areas  of  the  pronotum  unite  behind  the 
carina  and  the  pygidium  is  entirely  devoid  of  hairs,  as  in  the  male, 
and  slightly  pointed.

0.  nudicauda  resembles  the  much  more  widespread  0.  rhinoceros 
very  closely,  but  the  elytra  are  much  less  coarsely  punctured, 
besides  which  the  pygidium  is  without  the  basal  fringe  in  the  male

Black  or  pitchy,  with  the  lower  surface  reddish  and  clothed  with  a 
short  tawny  pubescence.  It  is  elongate-cylindrical  in  shape.  The 
dypeus  is  sharply  forked,  with  the  points  directed  forwards,  and 
the  horn  rather  broad  at  the  base,  tapering  to  a  blunt  point  and 
rugosely  punctured  except  at  the  base  behiud.  The  pronotum  \s 
almost  as  long  as  it  is  broad,  strongly  margined  all  round,  with 
the  front  angles  sharp,  the  hind  angles  obliterated,  the  sides 
strongly  rounded  behind  and  convergent  in  front.  There  is  an 
approximately  oval  excavation  extending  from  the  front  to  beyond 
the  middle  of  the  disc  and  surrounded  by  a  smooth  carina  which 
forms  behind  a  short  truncate  process  directed  forwards.  There  is 
an  elongate  depression  outside  the  carina  on  each  side  and  another 
in  each  front  angle.  All  the  depressions  are  rugose  and  the 
remainder  of  the  surface  is  smooth  and  shining  but  minutely 
punctured.  The  scuteUum  is  rugose,  with  a  smooth  outer  margin  ; 
and  the  elytra  are  strongly  and  closely  punctured,  the  punctures 
being  annular  and  forming  a  juxta-sutural  line  and  three  pairs 
of  other  lines  i*ather  wide  apart,  with  closely  punctured  intervals  : 
the  sides  and  apices  are  more  finely  punctured.  The  propygidium 
is  very  large,  lobate  beliind  and  rather  closely  ridged  or  striated. 
The  front  tibia  is  armed  with  four  teeih,  the  uppermost  one 
small,  and  there  is  also  a  sharp  and  conspicuous  tooth  on  the  lower

280  DYNASTIN.E. 

Type  in  the  Uppsala  University  Museum. 

This  is  an  extremely  common  beetle,  familiar  in  many  parts  of 
the  East  as  the  Ehinoceros  Beetle  or  Black  Cocoanut  Beetle,  and 
is  one  of  the  two  great  enemies  of  the  Cocoanut  Pahn,  the  other 
being  the  Palm  Weevil  or  Red  Cocoanut  Beetle  {Rhynchophorus). 
The  latter  begin  their  attack  at  the  roots  and  tunnel  upwards  into 
the  tree,  but  the  Rhinoceros  Beetle  on  the  contrary  always  begins 
at  the  top,  the  soft  growing  point  of  the  tree,  and  works  gradually 
downwards,  assisted  by  the  decay  caused  by  the  entrance  of  water 
at  the  opening  made.  Its  depredations  have  been  described  by 
Mr.  L.  C.  Brown  in  the  Agricultural  Bulletin  of  the  Straits  and 
Federated  Malay  States,  1903,  p.  66,  and  more  exactly  by 
Mr.  Chas.  S.  Banks  in  the  Philippine  Journal  of  Science,  vol.  i. 
1906,  p.  143.  The  latter  states  that  the  beetles'  attacks  are  con- 
fined to  the  soft  tissues  near  the  top  of  the  tree,  and  holes  seen  in 
the  trunk  below  this  point  date  from  the  time  when  the  growing 
apex  was  here  located.  "  The  attacks  always  begin  during  the 
night  and  by  the  following  morning  it  will  frequently  have  entered 
so  far  into  the  burrow  as  to  be  protected  from  the  light.  It  then 
continues  its  feeding  until  a  gallery  of  considerable  size  has  been 

excavated Observation   has   shown    that    the    males   make 

burrows  as  well  as  the  females  and  it  is  probable  that  they  always 
accompany  the  latter  at  the  time  of  egg-laying,  retreating  from 

the  burrow  they  have  made  to  allow  the  female  access It  is 

rare  to  find  a  single  Cocoanut  tree  anywhere  in  the  Philippines 
\\hich  does  not  show  one  or  more  evidences  of  attack  by  this 
beetle.  It  is  the  pest  most  frequently  reported  by  farmers  and 
cocoanut  growers,  and  in  hundreds  of  trees  which  I  have  personally 
examined  large  holes  in  the  trunk,  distorted  leaf-stems,  or  ragged 
leaves  demonstrate  the  character  of  its  work.  The  insect  larva  or 
the  adult,  in  its  work  inside  the  tree,  frequently  cuts  off  the  tip  of 
the  embryo  leaf  or  the  tips  of  the  leaflets  on  one  or  both  sides 
of  the  midrib,  so  that  when  the  leaf  finally  grows  it  appears  as  if 
it  had  been  trimmed  with  a  pair  of  shears  or  as  if  a  triangle  had 
been  cut  from  one  or  both  sides.  The  fibres  severed  by  the  insect 
protrude  from  its  burrow,  giving  the  latter  a  ragged  appearance. 
During  the  daytime  the  beetles  are  freqtiently  encountered  in  very 
old  holes,  into  which  they  evidently  have  gone  for  the  purpose  of 
hiding."  Mr.  Banks  has  figured  a  standing  tree  in  which  nearly 
the  whole  interior  from  the  top  to  within  half  a  yard  of  the  ground 
has  been  hollowed  out  and  from  which  nearly  a  hundred  larvse 
were  taken. 

This  unfortunate  taste  for  the  cocoanut  tree  is  probably  an 
acquired  one,  for  the  larvte  are  also  found  in  a  variety  of  other 
situations  and  appear  to  have  a  remarkable  power  of  adapting 
themselves  to  circumstances.  They  will  flourish  in  rotten  wood, 
decaying  leaves,  sawdust,  manure  heaps,  etc.,  and  in  one  case 
70,000  grubs  are  said  to  have  been  taken  upon  one  estate  from 
the  ground  itself,  the  soil  being  a  very  rich  vegetable  mould.  The 
ground  was  flooded  in  order  to  destroy  them  (Agric.  Bull.  Straits

&  Fed.  Malay  States,  1904,  p.  18).  It  is  probable  that  their 
primitive  habit  is  to  feed  in  decaying  vegetable  refuse,  like  their 
kin  in  general  and  that  at  first  the  eggs  were  only  deposited  in 
standing  trees  when  decay  had  begun,  the  adult  beetles  perhaps 
resorting  to  the  palm  "  cabbage"  for  the  sake  of  its  juices.  They 
are  attracted  by  the  oozing  sap  when  leaves  have  been  cut  off  and 
the  removal  of  old  leaves  with  tlieir  tough  basal  sheaths  makes  the 
trees  more  vulnerable  at  that  point.  The  best  methods  o£  coping 
with  tlie  beetle  are  fully  dealt  with  by  Mr.  Banks  in  the  treatise 
quoted  above.

beneath. 

The  form  is  elongate  and  parallel-sided.  Th.Q.head\s,  rugose,  the 
2>ronotum  rugose  in  front  and  at  the  posterior  angles,  which  are 
well-marked,  and  smooth  and  shining  elsewhere.  The  scutellum  is 
rugose  and  setose  in  front  and  smooth  behind.  Each  eh/tron  has 
a  strongly  impressed  line  of  coarse  annular  punctures  adjoining 
the  suture  and  two  or  three  pairs  of  similarly  but  less  closely 
punctured  lines  upon  the  disc ;  with  irregularly  punctured 
intervals,  and  the  outer  margins  are  minutely  and  rather  scantily

strongly  punctured  towards  the  circumference  and  setose  at  the 
base  and  in  the  lateral  angles.  The  metasternum  is  coarsely  and 
scantily  punctured,  but  almost  smooth  in  the  hinder  part,  and  the 
ahdomen  is  very  sparingly  punctured. 

d .  The  head  is  armed  with  a  strong,  simple,  laterally-com-

the  excavation  is  rugose  except  in  the  middle,  its  sides  are  produced 
upwards  into  a  tooth  on  each  side,  and  the  hinder  part  is  smooth 
and  elevated  in  the  middle  into  a  hump,  which  is  produced 
slightly  forward  over  the  excavation  and  ends  in  two  blunt 
tubercles. 

In  small  males  the  curvature  of  the  sides  of  the  prothorax  is 
more  gradual,  the  posterior  angles  are  more  obtuse,  the  hump  is 
absent,  and  only  a  slight  anterior  depression,  bordered  by  two 
lateral  and  two  posterior  minute  tubercles,  remains. 

2  .  Tiie  head  is  armed  with  a  minute  acute  tubercle.  The  pro- 
thorax has  the  sides  curvilinear,  the  front  angles  acute  and  the 
hind  angles  obtuse ;  the  disc  is  moderately  convex,  irregularly 
I'ugose  in  front  and  in  the  hind  angles,  and  almost  smooth  behind, 
and  the  base  is  trisinuate.  The  sides  of  the  elytra  are  more  curvi- 
linear than  in  the  male.

Shining  black,  with  the  lower  surface  and  femora  reddish,  and 
scantily  clothed  with  tawny  hairs  at  the  sides  beneath.  The  form 
is  that  of  T.  martabani,  with  which  it  may  be  easily  confused,  but 
the  elytra  are  almost  smooth  and  impunctate,  having  only  a  deeply 
impressed    sutural    line  upon    each    and  a  few  large   irregular

impressions  or  vestigial  striae,  but  these  are  entirely  free  from 
punctures.     The  apical  margins  are  slightly  rugosely  punctured. 

S  •  The  armature  of  the  head  and  tliorax  is  the  same  as  that  of 
T.  martabani,  but  in  well-developed  specimens  the  posterior 
thoracic  horn  is  more  hollowed  out  in  front  and  its  lateral  edges 
are  more  sharply  carinate.  The  hind  angles  of  the  prothorax  are 
more  obtuse  than  in  that  species.

p.  346. 

Size  and  general  appearance  of  the  preceding  species,  but  the 
elytra  are  each  decorated  with  a  strongly  impressed  sutural  stria, 
two  or  three  lines  of  punctures  at  the  lateral  margin,  some 
irregular  punctures  at  the  base  and  a  closely  and  irregularly 
punctured  area  at  the  apex.  The  scutellum  is  very  scantily 
punctured. 

(S  .  The  head  is  armed  with  a  moderately  long,  slightly  re- 
curved, laterally  compressed  horn.  The  sides  of  the  prothoraxare 
obliquely  produced  in  front  and  the  anterior  angles  directed 
forward.  The  sides  are  more  regularly  curved  behind  than  in 
2\  martahani  and  T.  monrjol  and  the  widest  part  of  the  thorax  is  at, 
or  a  little  before,  the  middle,  instead  of  behind  it.  The  base  is 
very  strongly  lobed  behind  and  elevated  into  a  hump,  which  is  not 
broadly  forked  in  front  but  bluntly  pointed,  the  point  showing 
only  a  trace  of  bifurcation. 

In  a  male  specimen  of  minor  development  the  armature  is 
reduced  to  a  condition  almost  indistinguishable  from  that  of 
similarly  undeveloped  examples  of  T.  monrjol.

posterior  half  elevated  into  a  broad  hump,  the  anterior  edge  of 
which  is  sharp  and  usually  forms  four  angles,  the  two  inner  ones 
a  little  in  advance  of  the  others.  The  scutellum  is  rather  short, 
rugose  and  hairy.  The  elytra  are  rather  feebly  punctured,  most 
of  the  punctures  falling  into  longitudinal  rows,  and  there  is  a 
deeply  impressed  stria  on  each  side  of  the  suture. 

S .  The  cephalic  horn  is  strongly  curved,  laterally  compressed, 
and  in  well-developed  specimens  bears  a  strong  blunt  tooth  at  the 
middle  of  the  posterior  edge.  The  pronotum  is  strongly  elevated 
behind  and  that  portion  is  entirely  smooth,  except  near  the  sides 
and  base,  where  it  is  rugosely  punctured.  The  anterior  half  is

upper  part  of  the  pygidium  is  a  little  punctured  and  hairy  and 
the  apical  part  smooth,  and  the  abdomen  is  almost  smooth 
beneath. 

2 .  The  cephalic  horn  is  simple,  less  strongly  curved,  and 
generally  shorter.  The  pronotum  is  similarly  shaped  to  that  of 
the  male,  but  rather  less  elevated  behind  and  coarsely  punctured 
at  the  summit  from  side  to  side.  The  anterior  part  is  rugose,  \^dth

261.  Eophileunis  decatenatus,  sp.  n. 

Black  and  shining,  with  a  very  scanty  clothing  of  stiff  tawny 
hairs  beneath.  The  size,  shape  and  genei'al  characters  are  those 
of  E.  cingalensis.  The  pronotum  is  coarsely  punctured,  but  less 
coarsely  than  in  that  species,  and  the  punctures  are  rather 
scattered  upon  the  hinder  pai't.  The  scutellum  is  irregularly 
punctured  and  the  elytra  are  decorated  with  very  coarse  annular 
punctures,  as  in  E.  cinrfalensis,  but  these  are  arranged  irregularly 
and  not  in  longitudinal  lines,  the  intervening  spaces  being  broken 
up  and  without  minute  punctures.  The  pygidium  is  closely 
punctured,  becoming  rugose  at  the  sides  and  base.  The  meta- 
sternum  is  decorated  at  the  sides  with  large  horseshoe-shaped 
impressions,  reduced  to  a  few  small  punctures  at  the  middle. 

The  sexual  characters  of  the  head  and  thorax  are  exactly  as  in 
£J.  cingalensis. 

Length  19*o-21*5  mm  ;  breadth  10-11  mm.

This  may  possibly  prove  to  be  a  variety  of  E.  cingalensis  with 
irregularly  punctured  elytra,  but  I  have  seen  E.  cingalensis  only 
from  Ceylon,  where  it  is  fairly  common,  whereas  the  present  form 
is  represented  by  four  specimens  from  Southern  India.

Eophileurus   uilgirensis,   Arrow,*    Trans.   Ent.    Soc.  Loud.   1908, 
p.  334. 

This  species  is  very  nearly  related  to  E.  planatus,  "Wied,,  but 
much  less  finely  punctured,  and  the  prothoracic  fovea  in  the  male 
is  circular,  extends  in  well-developed  specimens  considerably  past 
the  middle  and  is  not  bounded  behind  by  distinct  angulations-. 
^\iQ  prothorax  is  closely  punctured,  becoming  rugose  in  front,  and 
the  sculpture  is  only  a  little  coarser  than  in  E.  planatus.  The- 
sides  are  strongly  rounded  but  the  curvature  does  not  quite  reach 
the  posterior  angles,  which  are  rather  sharp.  The  scutellum  is 
irregularly  punctured.  The  elytra  are  closely  covered  with  coarse 
annular  punctures  arranged  in  definite  rows  and  there  are  a  very 
few  minute  punctulations  in  the  interstices.  The  pygidium  is 
rugose  at  the  base  and  scantily  punctured  at  the  apex,  and  the 
metasternum  is  densely  punctured  and  clothed  with  long  tawny 
hairs,  except  in  the  middle,  where  it  is  scantily  punctured  and  bare.

Genus  CLYSTER. 
Clyster,  Arrow,  Trans.  Ent.  Soc.  Lond.  1908,  p.  330. 

TrPE,  Scarabceus  itys,  Oliv.  (Malayan  Eegion). 

Range.  Burma  ;  Malay  Peninsula  ;  Java ;  Borneo,  etc. 

Form  cylindrical.  Clypeus  produced  and  truncate  in  front,  the 
frontal  suture  bearing  a  short  recurved  horn  in  the  male  and  two 
tubercles  in  the  female.  Mandibles  straight  at  the  sides  and  blunt 
in  front,  not  produced  beyond  the  clypeus.  Front  tibia  armed 
with  three  strong  teeth  and  secondary  denticles  ;  middle  and  hind 
tibiae  compressed  and  spinose,  digitated  at  the  end.  Tarsi  moder- 
ately slender,  the  front  ones  greatly  thickened  in  the  male,  with 
the  inner  claw  very  broad  and  cleft  at  the  end.  Propygidium 
rather  produced  behind,  with  almost  the  whole  median  part  finely 
striated. 

The  typical  species,  Cluster  itys,  Oliv.,  although  recorded  as 
Indian  in  the  Munich  Catalogue  of  Coleoptera,  appears  to  be  really 
confined  to  the  Malayan  Eegion  and  is  therefore  not  included  here.

Black,  or  piceous,  broadly  elongate-ovate.  The  head  is  coarsely 
rugose,  with  the  front  bitubereulate  and  rather  broad  at  the  anterior 
margin,  which  bears  two  minute  tubercles  placed  near  together. 
The  pronotum  is  almost  iiupei'ceptibly  punctured  at  the  sides,  with 
the  lateral  margins  broadly  curved  and  slightly  narrowed  anteriorly, 
the  front  angles  acute  and  the  hind  angles  obtuse.  The  scutdlum 
is  smooth.  The  ehjtra  show  a  vestige  of  a  punctured  sutural  stria 
and  four  pairs  of  lines  of  strong  punctures,  the  first  two  pairs 
abbreviated  behind  ;  there  are  a  few  similar  punctures  in  the 
intervals  and  the  lateral  and  apical  borders  are  strongly  and  ir- 
regularly punctured.  The  propygidium  is  scarcely  punctured  and 
the  stridulating  files  are  rather  distant  and  very  finely  sculptured. 
The  pygidium  is  finely  and  densely  punctured,  except  towards  the 
apex.  The  front  tibia  is  furnished  with  three  strong  acute 
teeth  and  supplementary  denticles. 

(S .  The  front  tarsus  is  slightly  thickened  and  the  inner  claw 
very  short,  thick  and  strongly  curved,  with  a  strong  basal  lobe. 

The  species  resembles  II.  punctolineat^is.,  Fairm.,  but  the 
marginal  tubercles  of  the  clypeus  are  placed  closer  together,  the

Black,  extremely  smooth,  and  rather  short  and  broad.  The 
head  is  rugose,  with  an  inconspicuous  carina  before  the  eyes, 
broadly  interrupted  in  the  middle.  The  clypeus  is  produced  into 
two  rather  sharp  reflexed  teeth.  The  iwothorax  is  closely  punc- 
tured along  the  extreme  posterior  margin,  but  is  otherwise  smooth  ; 
it  is  slightly  narrowed  in  front  and  regularly  rounded  at  the  sides, 
with  the  front  angles  acute  and  the  hind 
angles  obtuse.  The  scuteUum  is  small 
and  vaguely  punctured  at  the  base.  The 
elytra  are  short,  widening  a  little  behind 
the  middle,  with  faint  traces  of  strite 
quite  devoid  of  punctures  ;  there  are 
a  very  few  punctures  at  the  shoulders 
and  tiie  outer  margins  are  very  minutely 
punctulated  behind.  The  2}ro2}ygidium 
is  finely  punctured  and  the  stridu- 
lating  files  narrow  and  not  reaching 
the  hind  margin.  The  pygidium  is

Type,  Geoimpes  piceus,  Y. 

liamje.  Southern  Asia. 

Ovate  or  cylindrical  in  form,  convex,  smooth  and  shining. 
Clypeus  attenuated  and  bidentate  in  front,  the  suture  represented 
by  a  pair  of  transversely  placed  tubercles.  Organs  of  the  mouth 
as  in  Heteronijclius,  the  mandibles  bilobed  externally.  Pronotum 
distinctly  punctured  and  sometimes  slightly  impressed  behind  the 
middle  of  the  front  margin,  regularly  rounded  and  not  closely 
fringed  at  the  sides.  Front  tibia  tridentate,  with  minute  denticles 
before  and  after  the  uppermost  tooth.  Hind  tibia  flattened  and 
spinose  and  tarsi  slender.  Propygidium  bearing  two  narrow 
longitudinal  stridulatory  files. 

The  sexes  are  alike  and  the  front  tarsi  not  thickened,  but  the 
inner  claw  of  the  male  may  become  very  feebly  enlarged. 

The  strongly  striated  elytra  and  functional  stridulatory  files,  as 
well  as  the  rather  differently  formed  hind  legs,  distinguish  this  genus 
from  Pentodon.  In  the  latter  there  are  sometimes  traces  of  a 
double  series  of  ridges  upon  the  propygidium,  but  the  files  are  always 
very  coarse  and  imperfect  and  the  ridges  do  not  nearly  reacli  the 
hinder  margin  of  the  segment.  The  recognised  species  of  Pentodon 
are  very  homogeneous  in  size  and  form  and  are  essentially  Palae- 
arctic  in  distribution,  whereas  the  present  group  consists  of  smaller 
species  of  rather  varied  form  and  is  apparently  confined  to 
Tropical  Asia.

Very  deep  red,  sometimes  black  above,  broadly  ovate,  convex, 
smooth  and  shining.  The  head  is  rugose,  with  a  slight  transverse 
carina  before  the  eyes,  interrupted  in  the  middle  and  generally 
bearing  two  tubercles  placed  close  together.  The  clypeus  is  trun- 
cate in  front,  where  it  bears  two  reflexed  teeth.  The  pronotum  is 
smooth  and  convex,  strongly  and  regularly  rounded  at  the  sides, 
without  anterior  impression  or  elevation,  very  minutely  punctured, 
the  punctures  being  stronger  at  the  sides  but  not  close.  The 
scutetlum  is  smooth  and  the  elytra  are  deeply  punctate-striate,  the 
punctures  more  or  less  annular  ;  the  apical  borders  are  irregularly, 
and  the  lateral  borders  lightly,  punctured.  The  stridulatory  files 
of  the  propygidium  vary  greatly  :  they  are  sometimes  continued 
to  the  posterior  margin,  broad  and  well-developed,  and  sometimes 
terminate  at  a  distance  from  it  or  are  reduced  in  the  hinder  part 
to  mere  vestiges.  The  pygidium  is  strongly  and  deeply  punctured, 
but  often  smooth  at  the  apical  part  only  or  everywhere  but 
the  sides.  The  metastemum  is  smooth,  usually  with  scattered 
punctures  at  the  sides,  and  the  abdomen  is  unpunctured. 

The  sexes  are  alike.

behind  the  middle  of  the  elytra.  The  Jiead  is  rugose,  with  two 
median  tubercles  and  a  well-marked  depression  behind  them,  and 
the  clypeus  is  bidentate.  The  pronotum  is  very  smooth,  finely 
punctured  in  the  region  of  the  front  and  hind  angles,  without 
anterior  impression,  well  rounded  at  the  sides  and  scarcely  nar- 
rowed towards  the  front.  The  scutellum  is  smooth  and  the  elytra 
are  rather  unequally  punctate-striate,  the  punctures  moderately 
large  and  irregular  at  the  lateral  and  apical  margins.  The  2^^'o- 
pygidium  is  finely  punctured  and  the  piigidium  coarsely  and 
closely.  The  metastemum  is  smooth,  with  a  few  punctures  at  the 
sides,  and  the  abdomen  unpunctured. 

<S .  The  inner  claw  of  the  front  tarsus  is  sharp  and  of  normal 
shape,  but  is  a  little  thickened  and  has  an  indication  of  a  basal 
lobe.

273.  Alissonotum  simile,  sp.  n. 

Black,  smooth  and  sliining,  convex  and  elongate-oval.  The  head 
is  like  that  of  A.  rangunense,  but  the  ante-ocular  ridges  are  a  little 
more  prominent.  The  pronotum  is  strongly  punctured  and  the 
punctures  are  dense  at  the  sides.  There  is  no  anterior  impression 
or  tubercle.  The  scutdlam  is  smooth  and  the  elytra  are  vei-y 
coarsely  and  deeply  punctured  in  rows,  the  apical  margins  being 
closely  and  irregularly  punctured.  The  stridulatory  files  of  the 
jrropygidhim  diverge  rather  strongly  at  their  ends  and  the  jw/^u^m?H 
is  coarsely  and  rather  closely  punctured.  The  luwer  surface  is

This  is  almost  of  the  same  size  and  shape  as  A.  piceum,  F.,  but 
a  very  little  larger  and  more  elongate.  It  is  black  and  shining, 
with  "the  legs  and  underside  piceous.  The  head  is  closely  rugose, 
bituberculate  in  front  and  armed  on  the  vertex  with  two  tubercles 
placed  moderately  far  apart.  The  'protliovax  is  very  distinctly  but 
not  closely  punctured,  the  punctures  being  finer  in  the  middle. 
There  is  a  faint  impression  just  behind  the  middle  of  the  front 
margin  and  a  slight  elevation  in  front  of  it.  The  scutellum  is 
broad  and  unpunctured.  The  elytra  have  each  a  very  deep,  not 
distinctly  punctured  sutural  stria  and  four  pairs  of  strongly  punc- 
tured striae,  the  first  and  seventh  interstices  being  irregularly 
punctured  and  the  third  and  fifth  having  each  an  incomplete  line 
of  punctures  ;  the  outer  and  apical  margins  are  strongly  and 
closely  punctured.  The  propygidium  is  slightly  produced  and

Alissonotum  crassum,  Arrow,*  Trans.  Ent.  Soc.  Lond.  1908,  p.  323. 

This  is  a  large,  black,  oval  insect.     The  head  is  coarsely  rugose 

and  bituberculate  above.  The  jrrothorax  is  closely  punctured,  the 
punctures  being  coarse  except  along  the 
middle,  where  they  are  fewer  and  finer. 
There  is  a  faint  impression  near  the 
middle  of  the  anterior  margin  and  a 
minute  elevation  in  front  of  it.  The 
lateral  margins  are  well  rounded,  hut  the 
hind  angles  are  not  entirel_y  obliterated. 
The  sciiteUum  is  broad  and  smooth.  The 
elytra  are  deeply  striated,  the  sutural 
stria  being  scarcely  punctured  and  the 
remainder  rather  strongly  so  ;  the  sub- 
sutural  interval  is  very  broad  and  irregu- 
larly punctured,  and  the  third  and  fifth 
have  each  an  incomplete  line  of  punctures ; 
the  outer  margins  are  finely,  and  the 
extremities  coarsely,  punctured.  The 
2yropy[iidium  is  produced  in  the  middle 
and  bears  two  long  and  finely  striated 

files  ;  the  remainder  of  the  surface  is  finely  rugose  and  pubescent.

Prosternal  process  erect  and  very  hairy.  Pronotum  subglobose 
and  strongly  punctured.  Elytra  closely  and  irregularly  punctured, 
sometimes  with  inconspicuous  striae,  Stridulatory  files  absent,  or 
coarse  and  incomplete.  Legs  stout,  the  front  tibia  armed  with 
three  strong  teeth  and  two  or  three  secondary  denticles  ;  the  hind 
tibia  not  flattened,  but  truncate  at  the  end  and  fringed  with 
numerous  close  short  spines.  Tarsi  short,  the  basal  joint  of  the 
hind  tarsus  flattened  and  triangular.

This  genus  differs  from  Alissonotum  by  its  rounder  clypeus,  the 
irregularly  punctured  elytra  and  the  absence  or  partial  atrophy  of 
the  stridulatory  files.  It  is  essentially  Pala^arctic  in  its  distribution,

appearance  as  well  as  its  habitat  and  is  only  provisionally  assigned

This  species  is  very  like  the  preceding,  but  smaller,  and  the 
jyrotJiorax  is  relatively  narrower,  the 
front  angles  sharper  and  the  hind 
angles  less  broadly  rounded.  The 
elytra  are  very  coarsely  and  deeply 
punctate-striate,  and  the  membranes 
to  which  their  apices  become  abruptly 
reduced  are  broad  and  conspicuous. 
The  pygidium  is  very  strongly  punc- 
tured, and  the  front  tibia  sharply 
tridentate  without  trace  of  an  ad- 
ditional tooth  as  in  the  other  two 
species.

into  a  slight  tooth  just  behind  the  front  margin  and  a  still  slighter 
one  at  the  middle.  The  cavity  is  rugose  and  the  remaining  surface 
of  the  pronotuin  smooth  and  minutely  punctured.  The  pygidium 
is  smooth,  convex  and  very  thinly  and  minutely  punctured. 

In  less  developed  males  the  cephalic  horn  is  shorter  and  tapers 
to  a  sharp  point  without  any  dilatation  at  the  end.  and  the  pro- 
thoracic  excavation  is  smaller. 

§  .  This  is  more  elongate  and  generally  larger.  There  is  a 
small  sharp  tubercle  upon  the  vertex,  directed  backwards.  The 
pronotum  is  entirely  convex  and  punctured,  the  punctures  being 
distinct  at  the  sides  and  base,  and  very  dense  and  confluent  in 
front  and  in  the  middle.  The  pygidium  is  not  very  convex  and 
is  punctured  and  thinly  clothed  with  erect  hairs.

This  beetle  is  destructive  in  its  larval  stage  to  rice-crops  and 
has  been  described  and  figured  in  all  its  stages  by  Mr.  II.  Maxwell 
Lefi'oy  in  '  Indian  Insect  Life,'  1909.  Specimens  sent  from  the 
rice-fields  were  reared  in  captivity  by  31r.  Lefroy  in  soil  in  which 
rice-plants  were  groxAing,  upon  the  roots  of  \^hich  they  fed.  The 
following  is  an  outline  of  the  life-history  : — 

The  egg  is  white  and  soft ;  when  first  laid  it  is  oval,  being  2  mm. 
in  diameter.  It  grows  larger  day  by  day  until  it  is  nearly  round 
and  3  mm.  in  diameter,  the  increase  in  weight  beuig  from  '04  grain 
to  '16  grain,  due  probably  to  the  absorption  of  moisture.  The 
larva  is  of  the  typical  fonu,  a  full  grown  one  measuring  36  mm. 
by  6  mm.  The  larva;  live  in  the  soil,  feeding  upon  tlie  roots  of  the 
rice,  and  there  is  no  indication  of  their  presence  but  pellets  of 
earth  thrown  up  near  the  plants.  When  full  grown  they  burrow 
down  a  foot  and  make  cells  of  consolidated  earth,  Mhich  are 
smooth  inside.  They  then  pupate.  The  periods  are  as  follows  : — 
The  eggs  are  laid  during  June  and  July,  and  hatch  in  five  to  eight 
days.  The  larvae  feed  during  July,  August,  and  September ;  they 
then  pupate,  the  pupal  period  being  eight  days  only.  The  beetles 
rest  in  the  soil  till  May,  when  they  become  active,  burrow  out,  fly, 
mate,  and  lay  eggs.  Prom  eight  females  only  thirty-four  eggs 
were  obtained,  but  perhaps  all  did  not  lay  eggs.  This  curious 
life-history  is  an  adaptiition  to  the  climate.  Some  showers  fall  in 
May,  before  the  monsoon,  and  the  beetles  then  emerge  ;  the  mon- 
soon breaks  in  June  and  then  the  eggs  are  laid,  the  larvae  finding 
plenty  of  food  and  soft  moist  earth ;  the  period  from  November  to 
May  is  dry,  the  earth  being  hard  and  no  rice  available. 

Mr.  Lefroy  has  never  heard  this  species  make  any  sound.

a  male,  is  evidently  a  female.

inwards.  The  propyrjidium  has  a  graduated  series  of  stridulatory 
ridges  at  the  middle,  very  fine  posteriorly  and  becoming  very 
coarse  towards  the  anterior  margin  of  the  segment.  Thepygidium 
is  finely  punctured. 

S .  The  clypeal  shield  of  the  head  is  produced  above  into  a 
sharp-pointed  short  horn,  slightly  curving  backwards.  The  pro- 
notum  is  very  deeply  excavated,  and  the  cavity  is  nearly  smooth 
and  gives  rise  at  its  hind  margin  to  a  short  elevation  limited  behind 
by  a  carina,  which  is  semicircular  or  (at  its  greatest  development) 
sharply  angular ;  above  the  cavity  the  pronotum  is  rugosely 
punctured  and  produced  forward  as  a  broad  horizontal  lamina, 
rapidly  narrowing,  truncate  in  front  and  abruptly  reflexed.  The 
propygidium  is  produced  at  the  middle  almost  to  the  extremity  of

the  median  part),  strongly  rounded  at  the  sides,  with  the  base 
gently  curved  and  bearing  a  distinct  impressed  marginal  line  and  all 
the  angles  very  blunt.  The  scuteUum  is  smooth  and  the  elytra  are 
strongly  and  uniformly  punctured,  most  of  the  punctures  forming 
deeply  impressed  double  rows ;  the  apical  angles  are  sharp  and 
slightly  produced  inwards.  The  propjigidhi.m  is  produced  behind 
and  the  median  part  covered  with  stridulatory  ridges,  extremely 
fine  anteriorly  and  becoming  coarse  at  the  hind  margin.  The 
2)ygidinm  is  finely  ])unctured. 

cJ .  The  head  and  pronotum  are  armed  as  in  B.  dcdalus,  but 
the  cavity  of  the  latter  is  deeper  on  each  side.  The  propygidium 
is  produced  almost  to  the  end  of  the  pygidium.

closely  and  shallow'ly  punctured  with  moderately  fine  pits,  some  of 
which  form  four  double  rows;  the  apical  angles  are  produced 
inwards,  forming  sharp  overlapping  tongues.  The  propygidium 
is  finely  but  not  very  deeply  or  regularly  striated  upon  its  posterior 
part  and  bears  anteriorly  several  transverse  bands  which  are  ex- 
tremely finely  and  sharply  striated,  l:\ie  pygidium  is  smooth  and

Type  in  the  British  Museum. 

A  single  male  has  been  presented  to  the  Museum  bv  Mrs. 
Christopher  Morris.  There  is  a  female  from  the  same  locality  in 
Herr  C.  Sternberg's  collection  and  one  has  been  sent  to  me  by 
Mr.  H.  Maxwell  Lefroy.  In  M.  Eene  Oberthiir's  collection  are 
a  male  and  female  from  the  Castelnau  collection  bearing  the 
locality  Madras.  They  are  smaller  and  uniformly  reddish  in 
colour,  but  in  other  respects  agree  with  the  type.
