﻿Eteteromerous 
  Coteoptera,

  Gibraltar 
  ; 
  not 
  uncommon, 
  in 
  tufts 
  of 
  grass, 
  &c. 
  

   Specimens 
  of 
  this 
  species 
  submitted 
  by 
  me 
  to 
  M. 
  Allard 
  

   have 
  been 
  named 
  by 
  him 
  as 
  H. 
  gossijinatus, 
  Eeiche, 
  an 
  

   insect 
  only 
  known 
  as 
  yet 
  from 
  Algeria. 
  These 
  Gibraltar 
  

   specimens, 
  however, 
  by 
  no 
  means 
  agree 
  with 
  either 
  

   Eeiche's 
  original 
  description, 
  or 
  with 
  the 
  subsequent 
  one 
  

   given 
  by 
  Allard 
  (Mittheil. 
  schweiz. 
  ent. 
  Ges., 
  v., 
  p. 
  191). 
  

   Both 
  authors 
  state 
  that 
  " 
  H. 
  gossypiatus 
  may 
  be 
  easily 
  

   distinguished 
  by 
  its 
  almost 
  cylindrical 
  form, 
  its 
  pro- 
  

   thorax 
  scarcely 
  broader 
  than 
  the 
  head, 
  and 
  its 
  hairy 
  

   clothing." 
  In 
  the 
  last-mentioned 
  character 
  H. 
  Walkeri 
  

   agrees 
  with 
  H. 
  gossypiatus 
  ; 
  but 
  its 
  general 
  shape 
  is 
  less 
  

   cylindrical, 
  and 
  the 
  prothorax 
  in 
  both 
  sexes 
  is 
  very 
  dis- 
  

   tinctly 
  wider 
  than 
  the 
  head. 
  In 
  various 
  other 
  par- 
  

   ticulars 
  it 
  also 
  diflfers 
  from 
  the 
  description 
  : 
  the 
  elytral 
  

   interstices 
  are 
  coarsely 
  (not 
  finely) 
  punctured, 
  the 
  elytra 
  

   themselves 
  are 
  distinctly 
  broader 
  at 
  the 
  base 
  than 
  the 
  

   prothorax, 
  the 
  scutellum 
  is 
  almost 
  smooth, 
  &c. 
  H. 
  

   Walkeri 
  is 
  nearly 
  allied 
  to 
  H. 
  inacellus, 
  Kr., 
  an 
  insect 
  

   inhabiting 
  the 
  same 
  locality; 
  but 
  is 
  easily 
  separable 
  

   from 
  it 
  by 
  the 
  long 
  pubescence, 
  the 
  very 
  much 
  more 
  

   finely 
  punctured 
  elytral 
  strise, 
  the 
  flatter 
  and 
  coarsely 
  

   punctured 
  interstices, 
  &c. 
  Like 
  many 
  other 
  species 
  of 
  

   the 
  genus, 
  it 
  varies 
  enormously 
  in 
  size. 
  The 
  male 
  has 
  

   the 
  three 
  basal 
  joints 
  of 
  the 
  anterior 
  tarsi 
  very 
  broadly 
  

   and 
  equally 
  dilated, 
  these 
  joints 
  being 
  as 
  wide 
  as 
  the 
  

   tibise 
  at 
  the 
  apex. 
  It 
  differs 
  in 
  various 
  particulars 
  

   from 
  H. 
  jiiligerus, 
  Kr., 
  H. 
  villosipennis, 
  Luc, 
  H. 
  inibe- 
  

   scens, 
  Kiist., 
  &c. 
  

  

  Helops

  Gibraltar 
  ; 
  under 
  stones, 
  in 
  tufts 
  of 
  grass, 
  flood 
  refuse, 
  

   &c. 
  ; 
  occasional.

  Tetuan 
  and 
  Tangier; 
  several 
  examples, 
  varying 
  

   enormously 
  in 
  size.

  known 
  from 
  Europe. 
  

  

  Helops 
  (Diastixus) 
  carlo, 
  Kiist.* 
  

  

  Gibraltar; 
  five 
  examples. 
  The 
  determination 
  is 
  made 
  

   upon 
  M. 
  Allard's 
  authority. 
  These 
  specimens 
  seem
