PREFACE. 


The  following  rules  have  been  prepared  for  the  purpose  of  aiding 
entomologists  in  deciding  questions  of  nomenclature  arising  in  their 
work.  In  preparing  them  the  various  codes  of  nomenclature  have 
been  freely  consulted  and  used,  articles  on  nomenclature  in  various 
journals  read,  and  pamphlets  on  the  subject  have  furnished  some 
points.  After  a  mass  of  matter  was  prepared,  copies  were  sent  to 
many  of  the  principal  systematic  entomologists  of  America,  in  fact 
all  whom  we  knew  to  be  interested  in  such  matters.  Nearly  all  have 
expressed  opinions  on  the  more  important  rules,  and  many  on  almost 
every  one.  Various  other  workers  have  been  consulted  personally 
and  the  published  utterances  and  catalogs  of  several  entomologists 
have  furnished  opinions.  After  being  worked  over  and  over  again 
the  rules  have  gradually  taken  shape,  often  far  from  their  original 
form.  They  have  been  subjected  to  some  use  in  catalog  making, 
type  fixation,  &c,  and  so  far  as  possible  they  are  brought  into  accord 
with  the  general  practice  of  entomologists.  The  result,  while  hardly 
satisfactory  to  any  one  entomologist,  expresses  the  opinion  of  sys- 
tematic workers  far  more  accurately  than  the  vote  of  any  committee. 

These  rules  do  not  represent  the  personal  desires  of  their  prepara- 
tors,  since  there  are  several  important  rules  which  have  been  accepted 
reluctantly  by  one  or  both  of  the  compilers  in  order  to  join  the  ma- 
jority of  American  systematic  entomologists.  As  they  stand  there 
will  probably  be  at  least  one  objector  to  every  rule,  but  we  hope  no 
one  will  object  to  all  of  them.  The  point  of  the  use  of  a  misidenti- 
fication  as  a  genotype,  and  that  on  a  name  in  synonymy  preoccupy- 
ing the  use  of  such  name  in  the  genus,  provoked  the  mosl  discussion, 
but  the  weight  of  opinion  and  of  practice  seems  to  sanction  the  rules 
as  herein  set  forth.  A  few  object  to  a  valid  specific  name  being  re- 
quired as  the  basis  of  a  genus,  but  by  far  the  greater  number  express 
themselves  as  in  favor  of  the  rule. 

Rarely  will  two  people  express  the  same  thought  in  the  same  lan- 
guage, and  likewise  two  persons  reading  the  same  statement  may 
disagree  as  to  its  meaning.  An  effort  had  been  made  to  express  the 
following  rules  in  language  as  plain  and  definite  as  possible,  and 
wherever  it  was  thought  helpful,  examples  are  inserted.  If  the  rules 
are  carefullv  considered,  in  conjunction  with  the  examples,  where 


4  THE    ENTOMOLOGICAL    CODE. 

given,  little  trouble  ought  result  in  their  use.  While  an  earnest 
effort  has  been  made  to  cover  all  the  questions  that  commonly  arise, 
completeness  in  this  matter  is  practically  an  impossibility. 

It  seems  scarcely  necessary  to  discuss  the  necessity  of  an  entomo- 
logical code.  Most  existing,  codes  fail  to  cover  in  a  definite  manner 
many  points  that  continually  arise  in  entomological  work,  or  the  lan- 
guage used  is  of  such  a  broad  or  indefinite  scope  as  to  require  official 
interpretation  to  make  the  meaning  evident.  Scarcely  an  entomolo- 
gist has  been  connected  with  the  preparation  of  the  larger  codes  and 
the  codes  prepared  by  entomologists  have  been  of  restricted  scope,  or 
made  with  certain  questions  in  view. 

Each  entomologist  of  much  experience  has  acquired  certain 
methods  of  dealing  with  points  arising  in  his  work,  usually  depend- 
ent upon  personal  judgment.  One  cannot  expect  that  many  active 
workers  will  sacrifice  their  personal  judgment  in  favor  of  a  consensus 
of  opinion.  But  the  new  worker,  without  established  ideas,  is  apt  to 
use  such  tools  as  will  do  his  work,  and  if  he  finds  at  hand  a  code  that 
will  answer  the  greater  number  of  the  questions  that  arise  he  will 
very  likely  use  it,  especially  if  it  is  clear  and  comprehensive  and  not 
subject  to  official  interpretation  and  decision.  That  the  present  code 
of  rules  will  be  found  helpful  to  many  workers  in  the  field  of  Ento- 
mology is  the  earnest  hope  of  the  compilers,

INTRODUCTION. 

1.  No  person  nor  committee  has  authority  to  interpret,  limit,  or 
extend  the  precepts  here  laid  down ;  every  user  interpreting  the  rules 
for  himself. 

2.  The  word  "VALID"  as  used  in  this  code  of  rules  means 
"WITH  STANDING  IN  NOMENCLATURE,"  and  the  word 
"INVALID"  means  "WITHOUT  STANDING  IN  NOMEN- 
CLATURE." 

Note. — Names  in  synonymy,  or  ones  preoccupied,  as  well  as  names 
in  use  may  be  valid,  having  standing  as  defined  above.  Invalid 
names  are  nomina  nuda. 

BINOMIAL  NOMENCLATURE. 

3.  All  species  of  insects  are  to  be  named  according  to  the  binomial 
system  of  nomenclature  as  applied  by  Linnaeus  in  the  10th  edition 
of  his  Systema  Naturae  of  1758.  This  consists  of  the  generic,  or 
general,  name  of  one  word,  and  the  specific,  or  trivial,  name,  of  one 
word,  or  a  hyphenated  word. 

Example. — Alpha  alba  L. 

Note. — If  a  "binary"  (two  categories  whether  named  or  not)  sys- 
tem were  adopted  as  the  basis  of  entomological  nomenclature  we 
would  be  compelled  to  go  back  to  the  first  edition  of  Linnaeus'  Sys- 
tema Naturae  of  1735,  as  the  use  of  the  generic  name  (independent 
of  the  specific  name)  dates  from  that  work. 

4.  The  nomenclature  of  any  author  who  has  not  followed  the  bi- 
nomial system  is  to  be  ignored.  Accidental  binomials  occurring  in 
the  works  of  such  authors  are  to  be  rejected  as  invalid,  and  accidental 
trinomials  in  works  otherwise  binomial  are  not  to  be  excluded. 

5.  The  use  of  a  French  binomial  (or  other  language  not  in  Latin 
form)  does  not  validate  the  name.  Thus  "Acridien  algerien"  Is  not 
available  under  the  code. 

6.  The  following  cases  shall  be  considered  as  complying  with  the 
requirements  of  binomial  nomenclature: 

(a.)  Where  the  Latin  name  of  the  foodplant  has  been  used  as  a 
part  of  the  name  of  an  insect  such  name  shall  be  considered  a  bi- 


6  THE   ENTOMOLOGICAL    CODE. 

nomial,  and  the  two  words  are  to  be  hyphenated  or  the  name  of  the 
foodplant  abbreviated  to  the  initial,  the  former  preferred. 

Example.— Cynips  quercus  palustris.  This  may  be  written  Cynips 
quercus-palustris,  preferably,  or  Cynips  q-palustris.  The  name  of 
the  foodplant  should  not  be  dropped  entirely. 

(b.)  If  an  author  in  an  index  to  plates  gives  a  specific  name  with 
plate  and  figure  reference  between  it  and  the  generic  name  such 
treatment  shall  be  considered  as  binomial,  even  where  the  generic 
name  is  more  than  one  word. 

Examples.— Amadis,  pi.  39,  fig.  c— Sphinx.     (From  Cramer.) 

Amalia,  pi.  383, fig. b.— Phal  Bomb.    (From  Cramer.) 

Note.— This  is  the  method  of  Stoll,  Cramer,  Drury,  &c,  whose 
names  have  always  been  accepted. 

(c.)  Where  an  author  writes  the  first  Latin  word  after  a  generic 
name  in  a  different  type  from  that  of  the  other  Latin  words,  or  puts 
it  in  parenthesis,  such  word  is  the  specific  name,  and  the  author  is 
considered  as  having  fulfilled  the  requirements  of  binomial  nomen- 
clature. 

7.  Names  based  on  hypothetical  insects,  or  knowingly  based  on  a 
composite  specimen  are  invalid. 

8.  Names  printed  as  provisional,  or  as  suggested  substitutes,  are 
on  the  same  basis  as  though  definitely  proposed. 

PUBLICATION. 

9.  Matter  printed  and  offered  for  sale,  or  existant  in  the  libraries 
of  public  institutions,  constitutes  publication. 

10.  Printing  shall  include  only  such  methods  of  reproduction  by 
which  an  edition  is  printed  by  use  of  type  from  one  original.  In  the 
case  of  plates,  a  name  engraved  on  the  plate  will  hold. 

11.  To  be  valid  for  the  purpose  of  entomological  nomenclature 
matter  must  be  printed  in  one  of  the  European  languages. 

12.  Names  distributed  in  connection  with  specimens  are  not 
thereby  validated. 

13.  Publication  of  new  names  in  newspapers,  either  daily  or 
weekly,  popular  magazines,  non-technical  agricultural  journals, 
school  programs,  programs  of  meetings,  or  in  price  lists  are  not  valid, 
no  matter  how  or  where  printed. 


THE    ENTOMOLOGICAL    CODE.  7 

14.  Additions  or  corrections  given  in  one  part  of  an  article  or 
work  to  matter  on  a  previous  page  of  that  same  article  or  work  are 
admissible  only  when  published  on  the  same  date. 

Example. — On  page  41  an  author  makes  a  new  genus,  Alpha  for 
a  single  species,  alba  n.  sp.  On  page  105  he  adds  a  second  species, 
X.  nigra  Jones,  to  the  genus.  Alpha  is  then  not  monobasic  unless  it 
is  shown  that  page  41  was  published  before  page  105. 

15.  The  date  of  a  publication  is  the  date  of  its  first  distribution. 
The  date  of  a  work  published  in  parts  is  the  date  of  first  distribution 
of  each  part.  In  cases  where  the  date  of  distribution  is  not  given  in 
or  on  the  publication  an  approximate  date  may  be  accepted  until  a 
more  definite  date  is  known.  There  are  a  number  of  ways  in  which 
such  approximate  dates  may  be  obtained,  such  as  the  date  of  first 
reception  of  the  publication  at  some  learned  society  or  public  institu- 
tion, the  review  of  the  publication  in  other  works,  etc.  Dates  shown 
to  be  false  shall  be  corrected. 

16.  If  reprints  are  distributed  in  advance  of  the  distribution  of 
the  general  article  or  volume,  they  become  separate  publications,  and 
date  from  such  distribution,  if  otherwise  conformable  to  the  rules. 

PRIORITY. 

17.  The  law  of  priority  applies  to  all  generic  names,  and  ones  of 
lower  grade,  published  since  January  1,  1758,  the  assumed  date  of 
publication  of  the  10th  edition  of  Linnaeus'  Systema  Naturse.  No 
name,  binomial  or  otherwise,  published  before  this  date  has  any 
standing  whatever  in  entomological  nomenclature. 

18.  In  case  two  conflicting  names  occur  in  the  same  work,  the  one 
on  the  earlier  page  shall  have  precedence  over  that  on  the  later  page; 
if  both  appear  on  the  same  page,  the  one  coming  first  on  that  page 
shall  have  precedence. 

19.  In  case  two  conflicting  names  are  published  in  separate  works 
in  the  same  year  or  the  same  month,  and  no  evidence  is  obtainable 
of  a  more  definite  date,  page  precedence  shall  obtain  until  more  ac- 
curate dates  are  determined. 

20.  In  case  two  conflicting  names  are  published  in  separate  publi- 
cations on  the  same  day,  no  account  of  longitude  nor  hour  shall  be 
taken,  but  absolute  page  and  line  precedence  shall  obtain. 


8  THE    ENTOMOLOGICAL    CODE. 

21.  If  a  publication  has  the  pages  unnumbered,  they  shall  be 
counted  as  though  they  were  numbered.  If  two  styles  of  page  num- 
bering (as  Roman  and  Arabic  numerals)  occur  in  the  same  work 
the  various  pagings  shall  be  considered  as  continuous. 

Example. — The  new  generic  name  Alpha  appears  on  page  xi  of  a 
work  comprising  preface  pages  i-xxi  and  text  pages  1-100.  On  page 
3  of  the  same  work  the  generic  name  Alpha  is  used  in  a  different 
sense  than  that  of  page  xi.  Then  the  name  on  page  xi  preoccupies 
that  on  page  3. 

22.  The  law  of  priority  shall  apply  where  different  stages  (except 
egg)  broods,  conditions,  sexes  or  forms  of  insects  have  been  described 
under  different  names. 

NAMES. 

23.  Generic  and  specific  names  should  be  taken  from  the  Latin  or 
Greek  languages,  but  any  combination  of  letters  in  Latin  form  is 
permissible.    The  letters  K  and  W  may  be  used  in  scientific  names. 

24.  Subgeneric  names,  and  all  of  higher  rank,  should  be  written 
with  a  capital  initial ;  the  specific  name,  and  all  of  lower  rank,  with 
a  lower-case  initial. 

25.  A  name  once  published  cannot  be  retracted,  even  by  the 
author.  Nor  does  the  author  of  a  name,  after  the  name  is  published, 
have  any  more  privilege  than  any  other  person  with  that  name. 

26.  A  name  invalid  at  its  first  appearance  can  never  be  made  valid 
for  that  date  by  any  subsequent  action. 

27.  The  author  of  a  name  is  the  one  who  validates  it;  however, 
when  one  author  publishes  the  manuscript  description  furnished  by 
another  and  anywhere  in  that  work  by  direct  statement,  use  of  dif- 
ferent type,  quotation  marks,  &c,  so  indicates  it,  the  name  validated 
by  the  publication  of  such  manuscript  (but  not  names  of  higher 
rank  dependent  thereon)  belongs  to  the  author  of  that  manuscript, 
But  the  mere  crediting  a  name  to  another  without  other  indication, 
the  use  of  "MSS.,"  "in  litt.,"  or  collection  label  does  not  convey 
authorship. 

Example. — Alpha  Smith,  1900;  an  invalid  generic  name.  In 
1910  Jones  uses  Alpha,  giving  Smith  1900  as  authority  and  date, 
and  prints  a  description  of  Alpha  alba  n.  sp.  furnished  by  Smith,  as 
clearly  indicated  by  quotation  marks  and  different  type.  Alba,  the 
species,  is  credited  to  Smith,  but  Jones  is  responsible  for  Alpha, 


THE    ENTOMOLOGICAL    CODE.  9 

the  genus.  However,  had  Jones  also  published  a  description  of  the 
genus  admittedly  furnished  by  Smith,  then  the  genus  would  also  be 
credited   to  Smith. 

28.  New  names  given  with  reference  to  figures,  or  previous  de- 
scriptions, belong  to  the  author  publishing   such    names,   whether 

credited  to  another  or  not. 

29.  Articles  without  signature,  or  with  ones  insufficient  for  iden- 
tification, are  to  be  credited  to  "anonymous,"  unless  there  is  internal 
or  later  evidence  proving  the  real  authorship. 

30.  Where  an  author  has  two  names,  or  has  changed  his  or  her 
name,  that  name  shall  be  used  which  is  used  in  the  article  quoted. 

31.  In  the  division  or  restriction  of  species,  genera,  families,  &c. 

the  typical  part  must  retain  the  original  name. 

32.  When  species,  genera,  families,  &c,  are  united  the  oldest 
name  shall  be  retained  in  use. 

33.  Names  used  by  Linnaeus  in  the  10th  edition  of  his  Systema 
Naturas  for  species  can  never  be  changed,  as  they  cannot  In'  homo- 
nyms, synonyms  (except  of  each  other),  nor  misidentifications  of 
previous  names,  since  nomenclatorially  there  are  no  names  before 
this  work.  Names  appearing  in  synonymy  in  this  work  may  be  used 
for  purposes  of  identification  of  species,  but  cannot  he  resurrected, 
being  permanent  synonyms. 

34.  Names  used  before  1758  are  not  validated  by  reprinting  after 
1758. 

35.  Names  may  be  divided  into  the  following  grades,  or  cate- 
gories : 

I.  Specific  names,  and  ones  of  lower  rank. 
II.  Generic,  and  subgeneric   names. 

III.  Superfamily,  family,  and  subfamily  name-. 

IV.  Superordinal,  ordinal,  and  subordinal  nam.-. 

36.  The  use  of  a  name  in  one  category  does  not  invalidate  it-  use 

in  another  category,  but  in  no  case  shall  the  same  name  be  used  twice 
in  Zoology  in  the  same  category  above  category  no.  1. 

37.  In  species,  subspecies,  varieties,  or  races,  the  same  aame  -hall 
not  be  used  twice  in  the  same  genus,  but  name-  of  lower  rank,  as 
hybrids,  seasonal  or  colorational  forms,  hermaphrodites,  gyandro- 
morphs,  sports.  &c,  may  be  used  twice  in  the  same  genus  but  not  in 
the  same  rank  immediately  above. 


10  THE    ENTOMOLOGICAL    CODE. 

Example. — Alpha  alba,  var.  minor,  form  longipennis  Jones. 
Alpha  alba,  var.  major,  form  longipennis  Smith. 

CATEGORY  I. 

(Specific  Names  and  Ones  of  Lower  Rank.) 

38.  A  specific  name  becomes  valid  when  published  in  connection 
with  a  description  or  figure  of  that  species,  or  with  reference  to  a 
previously  published  named  or  unnamed  description  or  figure,  or  to 
replace  a  valid  name  of  specific  or  lower  rank. 

39.  A  specific  name  published  without  reference  to  or  in  connec- 
tion with  a  generic  name  is  invalid. 

40.  The  citation  of  a  manuscript  name  as  a  synonym  of  a  valid 
name  does  not  of  itself  validate  the  manuscript  name,  its  status  being 
subject  to  the  rules  governing  new  names. 

Example. — Alpha  minor  Linn. 

(=  Alpha  nor  Latr.  MSS.) 

Alpha  nor  Latr.  is  still  but  a  manuscript  species,  even 
though  a  description  of  A.  minor  Linn,  is  therein 
included. 

41.  A  new  specific  name  mentioned  in  the  description  of  a  new 
genus  is  not  thereby  validated  unless  it  is  clearly  stated  that  the 
description  is  that  of  both  a  new  genus  and  a  new  species. 

42.  The  date  of  a  valid  specific  name  is  that  of  first  publication  of 
the  page  whereon  that  specific  name  becomes  valid. 

43.  The  name  (or  abbreviation)  of  the  author  of  a  specific  name 
is  placed,  without  intervening  comma,  after  the  specific  name. 

44.  If  a  species  is  removed  from  the  genus  in  which  it  was  origi- 
nally described  the  author's  name  may  be  placed  in  parenthesis  and, 
if  desirable,  the  name  of  the  person  responsible  for  the  first  use  of 
the  new  combination  may  be  placed  after  the  original  author's  name ; 
but  in  no  case  is  it  allowable  to  substitute  another  name  for  that  of 
the  original  author  of  the  species. 

Example. — Alpha  alba  Linnaeus,  when  transferred  to  the  genus 
Beta  by  Gray,  may  be  written : 
Beta  alba  Linn. 
Beta  alba  (Linn.) 
or  Beta  alba   (Linn.)   Gray, 
but  not  Beta  alba  Gray. 


THE    ENTOMOLOGICAL    CODE.  11 

45.  A  specific  name,  if  a  Latin  adjective,  should  agree  in  gender 
with  the  generic  name,  even  when  published  in  connection  with  a 
subgeneric  name  of  different  gender. 

46.  Arbitrary  specific  names  are  not  to  be  changed  to  agree  in 
gender  with  the  generic  name. 

Example. — Cossus  ore  Str.  is  not  to  be  changed  to  C088U8  orca, 
orcus,  or  orcidis. 

47.  A  specific  name  given  to  any  part  or  stage  (except  egg)  of  an 
insect,  or  to  the  cast  or  imprint  of  a  fossil  insect,  is  valid  if  otherwise 
available. 

48.  A  specific  name  based  wholly  on  a  cocoon,  case,  gall,  leaf- 
mine,  or  other  work  of  an  insect  is  valid,  if  otherwise  available,  only 
until  the  insect  itself  is  described,  when  that  name  and  authority 
replaces  the  one  based  on  the  work. 

49.  A  specific  name  of  an  insect  based  wholly  on  characters  of 
internal  anatomy,  on  habits,  or  on  anything  other  than  external 
characters,  or  invaginated  parts  of  the  exoskeleton,  is  invalid. 

50.  Rules  applicable  to  specific  names  apply  also  to  names  of  lower 
rank  except  as  provided  in  section  37  and  certain  of  the  following 
ones. 

51.  A  subspecific,  or  varietal,  name  is  a  trinomial. 

52.  One  of  the  subspecific  or  varietal  names  shall  be  a  repetition 
of  the  specific  name  and  have  the  same  type.  The  name  of  the 
typical  variety  is  usually  omitted. 

Example. — Papilio  glaucus  glaucus  Linn  (usually  written  Papilio 
glomus  L.). 
Papilio  glaucus  turnus  Linn. 

53.  The  name  of  a  race  is  a  quadrinomial,  and  is  usually  given  to 
a  local  form. 

Example. — Papilio  glaucus  turnus  incricanus  Linn. 

54.  A  misidentification  shall  not  be  perpetuated  as  a  valid  species. 

Example. — Fitch,  under  the  genus  (Ecanthus,  treats  and  describes 
a  species  (fasciatus)  which  he  considers  as  being  the  Oryllus  fasciatua 
of  DeGeer.  It  is  now  known  thai  the  insed  before  Fitch  was  no! 
DeGeer's  species.  Thus  the  name  (Ecanthua  faxchatua  cannol  hold 
for  the  species  treated  by  Fitch,  as  it  was  a  misidentification,  Dot  the 
proposal  of  a  new  species. 


12  THE    ENTOMOLOGICAL    CODE. 

55.  A  subspecies,  a  variety,  or  a  race  described  in  connection  with 
a  valid  generic  name  but  under  an  invalid  specific  name  (or  a  mis- 
identified  species)  is  validly  established  as  a  species,  but  the  status 
of  the  invalid  specific  name  is  unchanged. 

Example. — Jones  describes  a  new  variety  nigripes  of  Alpha  alba 
Smith  MSS.  Nigripes  stands  as  a  valid  species  of  Alpha  and  alba  is 
still  a  manuscript  name. 

56.  In  writing  the  subspecific  or  varietal  name  the  author  of  the 
species  is  omitted  and  that  of  the  subspecies  or  variety  given. 

Example. — Jones'  variety  alba  of  Smith's  Papilio  nigra  is  written 
Papilio  nigra  alba  Jones. 

57.  The  names  of  hybrids  may  be  written  with  the  male  parent 
first,  as  Papilio  philenor  X  Papilio  asterias,  or  as  a  fraction  with  the 
male  parent  above  as  Papilio  philenor. 

Papilio  asterias. 

Specific  Homonyms. 

58.  Homonyms  (that  is  the  same  name  for  two  different  things) 
are  of  two  classes,  primary  and  secondary;  primary  when  two  species 
are  described  originally  in  the  same  genus  under  the  same  generic 
name  (emended  or  misspelled) ,  and  secondary  when  they  are  de- 
scribed under  separate  genera  but  later  are  referred  to  the  same 
genus. 

59.  Specific  names  differing  only  in  gender  termination  are  con- 
sidered as  homonyms,  and  a  name  is  a  homonym  when  it  is  the 
same  as  the  corrected  form  of  an  earlier  name  emendable  under 
these  rules. 

60.  Specific  names  shall  be  considered  as  homonyms  which  are 
equivalent  in  established  Latin  usage,  as  in  the  following  examples: 

i  or  ii  at  the  end,  as  fitchi  and  fitchii. 

as  or  iee  at  the  end,  as  slossonse  and  slossonix. 

ev  or  eu  at  the  beginning,  as  euonomi  and  evonomi. 

i  or  ;'  at  beginning,  as  ianthinum  and  janthinum. 

03,  se,  or  e,  as  cceruleus,  cseruleus,  and  ceruleus. 

i  or  y,  as  silvaticus  and  sylvaticus. 

c,  ch,  or  k,  as  microdon,  mikrodon;  cochi,  kochi;  antochi,  and 
antoki. 


THE    ENTOMOLOGICAL    CODE.  13 

Ending  of  prefixes  in  i,  o,  or  a,  as  albipunctata,  albopunctata,  and 
albapunctata. 

r  or  rr  before  h,  as  hsem orhoidalis  and  haemorrhoidalis. 

61.  In  case  of  primary  homonyms  the  later  name  shall  be 
changed,  no  matter  to  what  genus  they  are  now  referred. 

62.  In  case  of  secondary  homonyms  the  earlier  one  shall  retain 
the  name,  the  later  species  to  be  renamed.  This  shall  follow  no 
matter  which  is  first  referred  to  the  genus. 

Example. — Alpha  alba  Smith  1834. 
Beta  alba  Jones  1847. 
In  1848  Beta  alba  is  referred  to  the  genus  Delta,  and 

in  1852  Alpha  alba  is  also  referred  to  Delta.    Beta 

alba  Jones  must  be  renamed. 

63.  In  case  a  secondary  homonym  which  has  had  its  name 
changed  on  that  ground,  is  referred  out  of  that  genus,  its  former 
name  is  to  be  restored;  but  if  it  is  again  referred  to  that  genus,  or 
another  in  which  it  is  a  homonym,  the  previous  change  of  name 
again  becomes  effective. 

Example. — Alpha  alba  Smith  1824  is  referred  to  the  genus  Beta 
and  is  not  preoccupied  by  the  Beta  alba  Jones  1812.  which  has  been 
referred  to  the  genus  Delta.  But  if  now  the  Beta  alba  of  Jones  be 
re-transferred  to  Beta,  then  the  alba  of  Smith  will  have  to  be  re- 
named, or  if  it  had  been  renamed  before,  while  both  species  were  in 
Beta,  the  name  by  which  it  was  previously  replaced  comes  again 
into  use. 

64.  If  a  species  is  described  in,  or  referred  to,  a  genus  to  which  a 
species  of  the  same  name  has  at  a  previous  time  been  referred,  but 
does  not  now  belong  thereto,  the  later  name  shall  not  be  changed.1 

Example.— A Ipha  alba  Smith  L892.  In  L860  the  Beta  alba  of 
Jones  was  referred  to  Alpha,  but  later  referred  to  Delta;  the  Alpha 
alba  Smith  is  not  to  be  changed. 

65.  A  specific  name,  even  in  synonomy,  preoccupies  the  use  of 
that  name  in  (he  genus,  provided  the  synonym  is  a  valid  name. 

66.  Misspelled  specific  names  cannot  preoccupy  other  names,  but 
an  emended  name  and  names  suggested  as  substitutes  will  preoccupy 
in  both  the  emended  and  original  spelling. 


1  Entomologists  should  refrain  from  duplicating  combinations  which  have 
entered  largely  into  recent  literature,  such  as  Phyllodromia  germanica,  Dory- 
phora  decimlmeata,  Mytilaspis  ixnimnnii,   etc. 


14  THE    ENTOMOLOGICAL    CODE. 

67.  A  species  described  in  a  subgenus  is  also  described  in  the 
genus  to  which  the  subgenus  belongs,  and  any  future  combination 
of  that  name  with  either  the  genus  or  subgenus  constitutes  primary 
homonymy. 

Example. — If  a  new  species  be  described  as  Alpha  (Nala)  alba, 
then  a  later  Alpha  alba  or  Nala  alba  is  a  homonym. 

68.  Two  or  more  specific  names  in  the  same  genus  based  on  the 
same  root  but  spelled  differently,  except  gender  termination,  do  not 
conflict. 

Example. — Alpha  hispana  and  Alpha  hispanica  do  not  conflict. 

Emendations  and  Misprints  of  Specific  Names. 

69.  A  specific  name  once  published  shall  not  be  changed  except 
for  a  few  reasons.     The  following  rules  apply: 

a.  Where  a  name  is  clearly  based  on  a  food-plant,  host,  locality, 
or  a  person's  name  and  is  misprinted,  a  change  is  permissible. 

Example. — The  specific  name  of  a  parasite  said  to  have  been  bred 
from  Orgyia  was  originally  spelled  orvzise.  This  should  be  emended 
to  orgyise;  or  if  a  species  said  to  be  named  in  honor  of  Mr.  Brown  is 
spelled  brawni  it  should  be  changed  to  browni. 

b.  An  evident  misprint  shall  be  corrected. 

c.  Corrections  made  in  a  work  to  matter  on  a  previous  page  of 
that  work  shall  be  accepted  if  published  at  the  same  date. 

d.  An  evident  typographical  error  shall  be  corrected. 

e.  An  evident  error  in  spelling  a  valid  name  cannot  be  treated  as 
a  new  name. 

/.  A  properly  emended  name  takes  the  date  and  authority  of  the 
unemended  form. 

The  Type  of  a  Species. 

70.  The  type  of  a  species  is  a  single  specimen.  Specimens  other 
than  the  type  used  in  making  the  original  description  are  termed 
cotypes,  or  paratypes;  cotypes  when  no  type  is  designated,  paratype 
when  a  type  is  indicated.  Many  other  names  are  in  use  for  certain 
identified  specimens.    A  number  of  these  are  as  follows: 

Topotype.1 — A  specimen  from  the  original  locality. 


'A  topotype  of  an  insect  in  order  to  have  any  particular  value  should  be 
taken  at  the  same  general  time  of  year,  and  under  the  same  (ecological  con- 
ditions. 


THE    ENTOMOLOGICAL    CODE.  1 ." 

Metatype. — A  specimen  compared  by  the  author  of  the  species 
with  the  type  and  determined  by  him  as  conspecific  with  it. 

Homotype. — A  specimen  compared  by  another  than  the  author 
of  a  species  with  the  type  and  determined  by  him  as  conspecific 
with  it. 

Holotype. — A  single  specimen  selected  by  the  author  of  a  species 
as  its  type,  or  the  only  specimen  known  at  the  time  of  description. 

Syntype. — One  of  two  or  more  specimens  upon  which  a  species  is 
based  when  no  holotype  has  been  selected  (=cotype). 

Lectotype. — A  syntype  selected  as  a  holotype. 

Allotype. — A  paratype  of  the  opposite  sex  to  the  holotype. 

Monotype. — The  holotype  of  a  species  based  on  a  single  specimen. 

Chirotype. — The  type  of  a  manuscript  name. 

Plesiotype. — A  specimen  upon  which  subsequent  or  additional 
description  or  figure  is  based. 

Apotype. —  =  Plesiotype. 

Hypotype. —  =  Plesiotype. 

Neotype. — A  plesiotype  selected  to  represent  the  holotype  when 
the  holotype  is  lost  or  destroyed. 

Heautotype. — A  specimen  named  by  the  author  of  a  species,  or 
one  used  by  him  for  figuring.     Practically  a  metatype. 

Plastotype. — A  cast  of  a  type. 

Morphotype. — The  type  of  the  dimorphic  form  of  a  specie-. 

Autotype. —  =  Heautotype. 

Homeotype. —  =  Homotype. 

Ideotype. — A  metatype.  but  a  specimen  not  from  the  type  locality. 

Androtype. — Male  type,  Gynetype — female  type. 

Various  combinations  of  the  above  have  been  used  and  many 
other  names  could  be  given  for  particular  conditions  in  entomology, 
as  for  specimens  from  the  same  nest,  as  the  type  of  social  species,  the 
descendants  of  the  type  of  a  species  described  from  living  specimens, 
from  the  same  batch  of  eggs,  from  the  same  host,  &C. 

71.  In  the  case  of  Coccids  or  other  insects  where  a  description  is 
based  on  specimens  in  the  natural  condition,  and  on  ones  mounted 
on  slides,  the  specimens  in  the  natural  condition  may  !"■  considered 
as  type  material,  and  the  slide  (or  one  of  the  slides  if  there  are  more 
than  one)  as  the  type  slide,  but  in  case  of  doubt,  or  a  mixture  of 
species,  the  type  slide  shall  retain  the  name. 


16  THE    ENTOMOLOGICAL    CODE. 

72.  In  case  of  minute  insects  or  acari  where  more  than  one  speci- 
men is  mounted  on  a  slide  one  should  label  but  one  slide  as  the  type 
slide,  and  if  there  is  doubt  or  a  mixture  of  species  it  shall  be  treated 
as  a  case  where  the  author  has  labeled  more  than  one  specimen  as 
type. 

73.  The  following  rules  apply  for  the  fixation  of  types  of  species 
in  the  order  given: 

A.     Author's  Fixation  in  the  Original  Description. 

a.  If  a  specific  name  is  based  on  but  one  specimen,  that  specimen 
is  the  type. 

b.  If  an  author  labels  or,  in  the  original  description,  designates  a 
certain  specimen  as  type,  that  specimen  is  the  type. 

c.  If  an  author  in  the  original  description  designates  a  series  or 
collection  of  specimens  as  type,  then  the  type  is  among  such  desig- 
nated material. 

Note. — Obvious  errors  or  transposals  of  labels  are  sufficient 
grounds  for  disregarding  rules  b  and  c. 

B.     Fixation  by  Others  than  the  Author,  or  by  the  Author 
Subsequent  to  the  Original  Description. 

d.  A  specimen  to  be  chosen  as  type  must  be  found  among  ma- 
terial presumably  examined  by  the  author  at  the  time  of  its  descrip- 
tion. 

e.  The  type  shall  not  be  selected  from  among  material  indicated 
in  the  original  description  as  variational  or  aberrational,  nor  from 
material  doubtfully  included  in  the  species. 

/.  If  it  is  anywhere  stated  in  a  work  that  a  new  species  described 
therein  is  based  on  material  wholly  from  a  source  other  than  the 
author's  own  collection,  the  type  is  to  be  selected  from  among  such 
material. 

g.  If  there  are  distributed  to  two  or  more  collections  specimens  of 
a  species  all  labeled  by  the  author  as  types,  or  none  labeled  as  types, 
the  type  should  be  selected  from  the  specimens  retained,  if  any,  in 
the  collection  of  the  author.  In  case  of  a  joint  work  the  first  author 
has  precedence. 

h.  If  two  or  more  species  are  included  in  the  original  series  of 
specimens  upon  which  a  new  species  has  been  based  and  the  author 


THE    ENTOMOLOGICAL    CODE.  17 

has  not  labeled,  nor  has  he  nor  any  one  else  designated  one  as  type, 
nor  restricted  the  type  material,  and  it  results  that  one  of  the  in- 
cluded species  is  a  synonym  of  an  older  valid  species  or  has  been 
afterwards  (knowingly  or  unknowingly)  described  as  a  new  species, 
then  the  type  is  restricted  to  the  remaining  material. 

Example. — Alpha  alba  Latr.  1831,  described  without  type  fixation 
from  two  specimens,  a  and  b,  which  prove  to  represent  two  species,  a 
proving  to  be  the  Alpha  brunnea  of  Linn.  1768.  Thus  the  type  of 
Alpha  alba  Latr.  is  the  specimen  b  by  restriction  according  to  the 
above  rule.  The  same  would  have  resulted  had  the  species  a  been 
described  as  new  prior  to  the  type  designation  of  alba. 

i.  The  first  intentional  definite  type  designation  in  accord  with 
the  above  rules  is  final.  The  mere  reference  to  a  specimen  as  type 
is  not  to  be  considered  as  type  fixation. 

74.  Where  the  type  of  a  species  is  lost,  or  destroyed,  the  firsi  in- 
terpretation shall  obtain  unless  later  acquired  information  clearly 
proves  it  should  be  otherwise,  when  a  change  is  allowable. 

75.  In  cases  where  specimens  have  been  labeled  as  types  by  others 
than  the  author  of  the  species  such  type  labels  shall  be  interpreted 
independently  by  each  investigator  since  there  is  much  variation  in 
the  credibility  of  such  labels. 

76.  A  species  based  wholly  on  a  figure  has  the  original  of  that 
figure  as  the  type. 

77.  The  type  of  a  specific  name  proposed  to  replace  a  preoccupied 
specific  name  is  the  same  as  the  type  of  the  name  replaced,  irre- 
spective of  any  attached  description. 

78.  The  type  of  a  new  name  proposed  to  replace  a  misidentifica- 
tion  is  among  the  material  in  the  collection  of  the  author  of- the  new 
name,  if  there  is  inherent  evidence  that  he  had  material,  and  he 
gives  a  description  or  figure;  otherwise,  if  based  on  the  misidentifica- 
tion  of  a  specified  author  the  type  is  among  the  material  utilized  by 
such  specified  author  if  there  is  inherent  evidence  that  he  had  ma- 
terial. If  the  name  is  given  for  the  misidentification  of  several  or 
no  specified  authors,  then  the  type  may  be  selected  by  any  subse- 
quent worker  from  among  the  material  of  the  authors  concerned. 
If  it  results  that  there  is  no  described  material  hack  <>l'  a  name  based 
on  a  misidentification  or  mi  •interpretation  then  such  name  is 
invalid. 


18  THE    ENTOMOLOGICAL    CODE. 

CATEGORY  II. 

(Generic  and  Sub  generic  Names.) 

79.  A  generic  name  becomes  valid  when  published  in  connection 
with,  or  with  reference  to,  a  valid  (=  described  or  figured)  specific 
name,  or  to  replace  a  valid  generic  name. 

80.  A  description  without  mention  of  a  specific  name,  or  the  men- 
tion of  an  invalid  specific  name,  cannot  validate  a  generic  name. 

81.  A  generic  name  first  appearing  as  a  synonym  of  another  gen- 
eric name  is  valid  (and  may  preoccupy  or  replace)  if  there  be  a 
valid  specific  name  printed  in  connection  with  the  names ;  if  no  valid 
specific  name  is  there  cited,  the  synonym  is  invalid. 

82.  A  generic  or  subgeneric  name  is  a  homonym  and  subject  to 
replacement  when  it  is  spelled  exactly  like  a  previous  valid  generic 
or  subgeneric  name,  letter  for  letter.  However,  1  or  J,  and  Eu  or  Ev 
at  the  beginning  of  a  name  are  considered  the  same,  and  other  words 
that  are  equivalent  in  established  Latin  usage. 

Example. — Julus  and  lulus;  Euashmeadia  and  Evashmeadia; 
Elmis  and  Helm  is. 

83.  If  a  new  generic  name  is  proposed  as  new  it  shall  be  consid- 
ered as  new;  if  not  stated  to  be  new,  it  shall  nevertheless  be  con- 
sidered as  new,  unless  it  is  a  misspelling  of  a  previous  name. 

84.  A  name  which,  as  plainly  shown  by  the  text,  is  proposed  as 
an  emendation,  or  a  substitute  for  a  certain  indicated  generic  name, 
is  a  new  name  and  a  synonym  of  the  original  name,  and  can  pre- 
occupy and  replace. 

85.  All  other  variants  are  misspellings,  and  misspellings  are 
to  be  corrected. 

86.  Emendations  can  be  permitted  only  for  unpronounceable 
names,  or  for  misspelled  generic,  names  given  in  honor  of  a  person. 

87.  When  a  new  species  is  also  considered  as  representing  a  new 
genus  it  is  not  necessary,  although  advisable,  to  separate  the  two 
descriptions  in  order  that  both  shall  be  validated.  But  when  an 
author  proposes  new  genera  in  synoptic  tables  and  mentions  in  con- 
nection therewith  only  new  or  invalid  specific  names,  such  specific 
name  or  names  is  not  thereby  validated,  the  generic  name,  therefore, 
also  being  invalid  at  that  place. 


THE    ENTOMOLOGICAL    CODE.  19 

88.  A  genus  is  not  a  synonym  because  it  has  among  its  originally 
included  species  one  or  more  that  is  already  the  type  of  another 
genus. 

89.  Names,  when  used  and  treated  by  their  author  as  generic 
names,  are  such,  even  when  called  by  some  other  names,  as  "conors," 
&c. 

90.  To  rank  as  a  subgenus  a  name,  or  its  initial,  must  be  so  stated 
or  used,  or  placed  in  parentheses  between  the  generic  and  specific 
names.  Any  name  given  to  any  division  of  a  genus  and  neither 
designated  nor  used  as  a  subgenus  has  no  standing  in  nomenclature. 

Note. — There  are  thousands  of  such  names,  called  series,  cohors, 
divisions,  groups,  sections,  legions,  &c,  or  even  families  and  races. 
Such  have  not  been  cataloged  as  genera  nor  subgenera. 

91.  Subgeneric  names  are  subject  to  the  same  rules  as  generic 
names.  One  subgeneric  name  shall  be  the  same  as  that  of  the  genus 
to  which  it  is  subordinate,  and  its  type  the  same  as  that  of  the  genus. 

92.  A  genus  does  not  lose  its  genotype  by  becoming  a  subgenus, 
and  a  subgenus  on  becoming  a  genus  retains  its  former  type  if  it 
had  one;  otherwise  a  type  must  be  selected  from  among  those  sp 
originally  included  under  it  as  a  subgenus. 

Type  of  a  Genus. 

93.  In  every  genus  there  shall  be  one  species  known  as  the  type, 
or  genotype.  Two  essential  qualifications  of  a  genotype  are:  1st. 
It  shall  have  a  valid  name.  2d.  That  name  shall  have  been  origi- 
nally included,  without  question  in  the  genus. 

94.  No  specific  name  originally  quoted  in  synonymy  in  a  certain 
genus  can  be  accepted  as  the  type  of  thai  genus,  nor  one  doubtfully 
determined,  provided  there  are  others  available  for  type  citation 
under  these  rules. 

95.  Genera  with  but  one  originally  included  specific  name  (ex- 
clusive of  synonyms  and  subspecies  or  varieties)  are  monobasic  and 
genera  with  more  than  one  such  name,  not  including  synonyms,  are 
poly  basic. 

96.  The  genotype  of  a  monobasic  genus  is  the  only  specific  w.iww 
cited,  irrespective  of  misidentification  or  restriction. 

Example. — Alpha  Smith,  new  genus  with  a  single  specific  name 
included,  the  Beta  alba  of  Jones.    Then  Beta  <tli<<i  Jones  is  the  geno- 


20  THE    ENTOMOLOGICAL    CODE. 

type  of  Alpha  Smith,  even  if  it  later  results  that  Smith  did  not  know 
that  species,  what  he  thought  to  be  that,  being  in  reality  a  very 
different  species. 

97.  In  regard  to  the  genotypes  of  polybasic  genera  the  following 
rules  apply: 

a.  When  an  author,  in  describing  a  new  genus,  mentions  or  refers 
to  any  valid  specific  name,  except  one  doubtfully  included  or  quoted 
in  synonymy,  as  type,  typus,  genotype,  &c,  or  states  that  the  genus 
is  "based  on"  or  "erected  for"  (or  such  similar  phrase)  some  one 
species,  then  the  species  properly  represented  by  that  specific  name 
is  the  genotype,  irrespective  of  misidentification. 

b.  If  a  specific  name  not  originally  included  in  the  genus,  but 
with  an  originally  included  species  quoted  in  synonymy,  is  desig- 
nated as  the  genotype  of  an  established  genus  such  designation  is 
deemed  valid  for  the  species  in  synonymy. 

Example. — Alpha  Smith  1870,  based  on  two  new  species,  alba  and 
nigra.  In  1880  the  genotype  is  designated  as  "brnnnea  Jones  1860 
(==  nigra  Smith  1870)."  Then,  by  the  above  rule,  nigra  Smith 
1870  is  the  properly  designated  type  of  Alpha. 

c.  If  a  genus,  established  in  the  text,  is  also  given  on  a  previous 
page  in  a  synoptic  table  with  the  mention  of  a  valid  specific  name 
or  names,  the  type  is  not  thereby  selected  or  restricted. 

98.  If  the  author  of  a  polybasic  genus  has  not  established  the 
genotype  by  any  of  the  above  methods,  it  may  be  selected  by  any 
one  as  follows: 

a.  The  first  author  to  select  as  type  one  of  the  originally  unques- 
tionably included,  specific  names  fixes  the  genotype,  provided  such 
specific  name  has -not  already  been  properly  chosen  as  the  type  of 
another  genus,  and  such  selected  specific  name  represents  the  type, 
irrespective  of  misidentification. 

b.  If  all  the  originally  unquestionably  included  species  of  a  genus 
are  already  properly  selected  as  types  of  other  genera,  any  one  of 
them  may  be  chosen  as  the  type  of  this  genus. 

99.  A  specific  name  cited  as  the  genotype  with  a  query,  or  indi- 
cated as  the  probable  type,  is  not  thereby  the  type. 

100.  If  two  or  more  species  are  cited  at  one  place  as  types  of  one 
genus,  neither  is  thereby  the  type,  nor  is  type  selection  restricted. 


THE    ENTOMOLOGICAL    CODE.  21 

101.  If  all  but  one  of  the  species  of  a  polybasic  genus  are  types  of 
other  genera,  then  that  one  remaining,  if  otherwise  eligible,  is  the 
genotype. 

102.  If  all  but  one  of  the  species  of  a  polybasic  genus  are  removed 
to  other  genera,  but  not  as  types,  this  one  remaining  does  not  thereby 
become  the  genotype — that  is,  an  author  does  not  restrict  a  genus 
except  by  type  selection. 

Example. — Alpha  is  established  with  four  included  species,  none 
cited  as  type.  Later  species  1,  2,  and  4  are  removed  to  the  genus 
Beta,  but  none  of  them  as  its  genotype.  Species  3,  the  only  one  not 
removed  from  Alpha,  is  not  thereby  the  type  of  Alpha,  and  no  more 
eligible  for  type  selection  than  species  1,  2,  or  4. 

103.  The  citation  of  a  generic  name  in  synonymy  under  another 
generic  name  does  not  thereby  restrict  either  name. 

Example. — Alpha  is  described  with  four  originally  included  spe- 
cies. Later  Beta  is  described  with  Alpha  quoted  in  synonymy,  and 
with  the  species  1  and  2  included.  This  does  not  restrict  Alpha  tu 
the  species  1  and  2. 

104.  When  an  author  changes  a  generic  name,  or  unites  two  or 
more  genera,  the  genotypes  remain  unchanged. 

105.  The  type  of  a  newT  generic  name  which  by  sign  or  language 
is  clearly  shown  to  be  proposed  to  replace  another  valid  generic 
name  is  the  same  as  that  of  the  genus  replaced. 

106.  If  a  polybasic  genus  without  designated  genotype  contains 
among  its  originally  unquestionably  included  species  one  not  in 
synonymy  and  of  the  same  name  as  the  generic  name.  I  lien  that 
species  is  the  genotype  (type  by  absolute  tautonomy). 

107.  Genotypes  fixed  according  to  the  above  rules  are  stable,  and 
cannot  be  changed.  No  other  form  of  genotype  designation  than 
distinctly  indicated  above  shall  be  valid  ;  therefore  the  use  of  "n.  gen. 
n.  sp.,"  "sensu  strictorum,"  the  repetition  of  generic  characters  in 
the  specific  description,  the  first  species,  the  most  common  species,  a 
medicinal  species,  a  figured  species,  nor  one  with  the  life  history 
given  shall,  of  itself,  be  considered  as  genotype  fixation. 


22  THE    ENTOMOLOGICAL    CODE. 

CATEGORY  III. 

(Superfamily,  Family,  and  Subfamily  Names.) 

108.  The  name  of  a  family  shall  be  formed  by  changing  the  last 
syllable  of  the  genitive  case  of  an  included  generic  name  (preferably 
the  oldest)  into  idse. 

109.  The  name  of  a  subfamily  shall  be  formed  by  using  "inx"  in 
place  of  the  idse.  One  of  the  subfamily  names  shall  be  based  on  the 
same  generic  name  as  that  of  the  family  of  which  the  subfamily  is  a 
part. 

110.  The  name  of  a  superfamily  shall  be  formed  by  replacing  the 
"idse"  of  one  of  the  included  family  names  with  "oidea." 

111.  The  name  of  a  tribe  (a  prime  division  under  the  subfamily) 
shall  be  based  on  that  of  an  included  genus,  and  shall  end  in  "ini." 
One  of  the  tribes  under  a  subfamily  shall  be  based  on  the  same 
generic  name  as  that  on  which  the  subfamily  is  based. 

112.  The  name  of  a  subtribe  (a  prime  division  under  the  tribe) 
shall  be  based  on  an  included  genus  and  end  in  "ina."  One  of  the 
subtribes  shall  be  based  on  the  same  genus  as  that  of  the  tribe  of 
which  it  is  a  part. 

Note. — The  term  "group,"  formed  by  adding  "set'  to  the  stem  of 
a  genus,  is  used  by  many  under  the -tribe,  subtribe  or  subfamily,  but 
the  term  is  used  also  for  other  grades  and  is  inadvisable  owing  to 
this  confusion. 

113.  The  name  of  a  family  or  subfamily  is  to  be  changed  when 
the  basic  generic  name  is  a  homonym,  or  is  removed  from  the  family 
or  subfamily,  or  becomes  a  synonym. 

114.  If  there  are  two  or  more  names  proposed  for  the  same  family 
or  subfamily  ending  in  idse  or  insc,  the  earlier  name  shall  be  adopted. 

115.  If  there  are  two  family  or  subfamily  names  of  the  same 
spelling,  the  more  recent  shall  be  replaced,  or  so  modified  as  not  to 
conflict. 

CATEGORY  IV. 

(Superordinal,  Ordinal,  and  Suborddnal  Names.) 

116.  The  names  of  superorders,  orders,  and  suborders  have  no 
relation  in  formation  to  names  of  lower  rank. 

117.  No  change  in  the  commonly  accepted  names  in  this  category 
should  be  made  for  any  cause,  but  when  two  or  more  names  are  in 


THE   ENTOMOLOGICAL    CODE.  23 

use  for  one  group  of  insects,  as  Physapoda  and  Thysanoptera  for 
thrips,  or  Siphonaptera  and  Aphaniptera  for  fleas,  the  earlier  should 
be  used. 

Status  of  Invalid  Names. 

118.  If  an  author  publishes  a  manuscript  name,  or  any  other 
name  that  is  invalid,  such  name  may  be  adopted  later  by  any  author 
for  any  purpose,  and  it  will  date  from  the  first  valid  usage,  and  be 
credited  to  the  validating  author,  no  matter  in  what  sense  used. 

Example. — Alpha  alba  Smith  1834,  MSS.  does  not  preoccupy 
Alpha  alba  Jones  1867.  Likewise  the  generic  name  Beta  Smith 
1834  without  included  species  does  not  preoccupy  Beta  Jones  1867 
validly  established. 

RECOMMENDATIONS. 

119.  Reprints  should  always  bear  the  name  and  volume  of  the 
publication  and  the  original  pagination. 

Titles  should  indicate  the  Order  or  Family,  preferably  both,  to 
which  the  insects  discussed  belong,  and  if  the  article  treats  of  the 
fauna  of  one  general  region  that  fact  should  also  appear  in  the  title. 

Follow  some  plan  in  making  descriptions,  segregate  the  matter 
relative  to  one  part  or  pertaining  to  the  color,  &c.  Comparative 
notes  relative  to  an  allied  species  in  the  same  genus,  where  sue!) 
occurs,  is  recommended. 

A  new'  genus  or  species  should  be  clearly  indicated  as  such  ami 
should  be  noticeably  set  off  in  position  or  type,  not  obscurely  pro- 
posed in  the  midst  of  a  paragraph  or  other  inconspicuous  position. 

A  description  should  be  given  separately  for  each  new  genus  mil 
species  and  their  types  indicated. 

When  descriptions  of  new  genera  or  species  are  given  in  languaj 
other  than  Latin,  German,  French  or  English  it  is  well  to  include  a 
diagnosis  in  Latin. 

New  species  should  not  be  based  on  the  early  stages,  dot  on  the 
work  of  insects. 

Do  not  make  overlong  descriptions  nor  titles. 

In  describing  new  species  a  figure,  especially  of  distinguishing 
characters,  should  be  given. 

The  Metric  system  of  measurements  should  he  used  in  all  scientific 

works. 

A  name  should  be  euphonious,  and  of  moderate  length.  Hybrid 
names  should  be  avoided. 


24  THE    ENTOMOLOGICAL    CODE. 

In  some  groups  it  is  customary  to  have  uniform  terminations  or  a 
common  root,  thus  facilitating  reference.  Examples  are  tortricid 
specific  names  ending  in  ana,  and  tineid  names  ending  in  ella,  &c. 

Names  taken  from  native  languages,  such  as  Indian,  Malay,  Phil- 
ippine, &c,  are  often  found  useful  when  latinized  for  names  of 
genera  and  .species. 

Personal  names  should  be  used  sparingly,  especially  for  genera. 
The  British  Association  in  1865  well  said:  "The  handing  down  the 
name  of  a  naturalist  by  a  genus  has  always  been  considered  as  the 
highest  honor  that  could  be  given,  and  should  never  be  bestowed 
lightly." 

To  form  generic  names  from  personal  names,  if  the  name  ends  in 
e,  i,  o,  u  or  y  add  a,  us  or  um  to  the  name.  If  it  ends  in  a,  then  ia 
is  added  to  the  name.  If  it  ends  in  a  consonant  add  ia,  mm  or  ius 
to  the  name. 

In  latinizing  personal  names  for  use  as  specific  names  the  usual 
rule  is  to  add  i,  if  masculine,  or  se,  if  feminine;  but  in  many  cases 
where  the  name  ends  in  a  vowel  it  is  better  to  change  that  vowel  to  i 
and  add  i  or  se.  Often  names  ending  in  o  should  have  i  or  se  added 
to  the  genitive  of  the  name. 

Example. — An  insect  named  in  honor  of  Mrs.  Slosson  is  slossonse, 
one  named  for  Mr.  Smith  is  smitlii,  one  for  Latreille  is  latreillii,  and 
one  for  Antonio  is  antonini. 

A  specific  name  based  on  that  of  a  country  should  take  its  root 
from  the  Latin  name  of  that  country,  if  there  is  one.  Thus  an 
insect  from  Spain  should  be  called  hispanus  or  hispanicus,  not 
spainus  nor  spainicus. 

Two  names  in  the  same  genus  should  not  be  based  on  the  same 
Latin  root.  Thus  hispanus  and  hispanicus  in  the  same  genus  are 
objectionable. 

Prefixes  or  suffixes  of  a  generic  name  are  useful  in  forming  names 
for  segregates  of  a  genus,  as  Ilybius,  Ilybiosoma,  Galeruca,  Galeru- 
cella,  Dachne,  Megalodkichne,  Hypodachne,  &c. 

In  making  names  based  on  words  having  diacritic  marks,  such 
marks'need  not  be  retained,  as  Stalia,  in  honor  of  Stal. 

Names  expressing  diminution  or  resemblance  are  often  helpful, 
as  Tettix,  Tettigelfa,  Climacia,  Glimcucina. 

In  general  it  is  not  advisable  to  fix  genotypes  for  genera  with 
which  the  writer  is  unfamiliar. 

In  subdividing  a  genus  it  is  well  to  have  the  new  genera  agree  in 


THE    ENTOMOLOGICAL    CODE.  25 

gender  with  the  old  one  in  order  that  no  changes  will  be  required  in 
the  termination  of  specific  names. 

When  a  new  generic  name  is  based  on  an  old  species,  the  former 
generic  name  of  the  old  species  should  always  be  cited. 

Before  changing  the  name  of  a  supposed  secondary  homonym  care 
should  be  taken  to  ascertain  quite  surely  the  generic  position  of  both 
species. 

The  name  of  the  author  should  be  given  in  conjunction  with  a 
specific  name. 

In  abbreviating  words  the  following  rule  is  usually  good:  Stop 
before  the  second  vowel  unless  the  resulting  abbreviation  contains 
but  one  consonant,  in  which  case  stop  before  the  third  vowel. 

Examples. — Washington,  Wash. ;  History,  Hist, ;  Academy.  Acad., 
&c. 

In  the  abbreviation  of  author's  names  it  is  recommended  to  follow 
the  custom  of  the  author  himself. 

Do  not  make  generic  names  similar  to  ones  already  in  use.  or  of 
the  same  pronunciation. 

Various  signs  have  been  used  to  indicate  certain  facts  about  names 
in  synonymy,  not  always  with  the  same  meaning.  The  following 
six  signs  are  recommended  for  constant  use  with  the  moaning  here 
given : 


=  primary  homonym.  $  =  male. 

#  =  secondary  homonym.  9  =  female. 

f  =  misidentification.  ?=  neuter,  worker. 

Many  other  signs  have  been  used,  some  in  different  senses.  A 
number  are  here  given,  and  if  they  are  made  use  of  it  is  recom- 
mended that  they  be  used  in  the  sense  quoted  below : 

§  =  figure  of  typical  specimen.  J)  =  pupa. 

!   =  specimen  examined.  £  =  hermaphrodite. 

—  =  shorter  than.  *  — many   different    things,   and 

+  =  longer  than,  should  be  used  only  to  in- 

<  =  falling  short  of.  dicate  a  footnote,  when  but 

>  =  extending  beyond.  one  occurs   on    a   page,   or 

O  =  adult.  where  the  use  is  explained 

P)  =  egg  lu    ''K'   work    ni    wn'rn    it 

0  =  larva.  appears. 

Footnotes  are  best  indicated  by  arabic  numerals. 


26  THE    ENTOMOLOGICAL    CODE. 

For  the  sake  of  uniformity,  it  is  recommended  that  the  following 
scheme  of  grouping  be  followed  in  the  order  indicated  below  when- 
ever applicable: 

Order.  Genus. 

Suborder.  Subgenus. 

Superfamily.  Species. 

Family.  Subspecies  or  variety. 

Subfamily.  Race. 

Tribe.  Aberration,  sport,  &c. 

Subtribe. 

• 

In  cataloging,  the  employment  of  a  small  serial  number  after  each 
reference,  to  be  repeated  in  connection  with  the  citation  of  informa- 
tion therein  given,  will  indicate  the  authority  for  each  item. 

Example. — Beta  alba  (Smith). 

Alpha  alba  Smith,  Proc.  Ent.  Soc.  Paris,  vol.  xii,  p. 
76  (1900)  (i);  Jones,  Rev.  Ent.  Inf.,  vol.  ii,  p.  7 
(1904)  <2>  ;  Beta  alba  Brown,  Ent.  Journ.,  vol.  lv, 
p.  80  (1911)  <3>. 

Hab.— United  States*1-3);  Mexico*2). 

Feeds  on  Salix^  ;   $   dimorphic (2). 

Thus  Brown  is  responsible  for  the  statement  that  it  feeds  on  Salix, 
and  Jones  for  the  male  being  dimorphic,  and  occurrence  in  Mexico.
