NEW  GENERA  AND  SPECIES  OF  COLEOPTEROUS  INSECTS. 
109 
I  possess  another  species  of  this  genus,  which  is  also  from  New  Holland,  and  which 
I  have  designated  Ur.  sericeus. 
Genus.  Scolecobrotus^ 
Antennce  12-articulat0e,  corpore  longiores,  articulis  prioribus  tribus  Ur  acanthi 
similibus,  sequentibus  sequalibus  serratis  erosis,  externo  breviore  scal- 
pelliformi  subserrato. 
In  cseteris  Uracantho  simillimus. 
This  genus  possesses  many  characters  in  common  with  the  preceding,  but  is  at  once 
distinguished  from  it  by  the  antennce,  which  in  Ur  acanthus  have  eleven  joints,  whereas 
in  Scolecobrotus  there  are  twelve,  all  of  which,  except  the  first  three,  are  serrated  ;  the 
last  joint  also  is  shorter  than  those  which  precede  it,  and  resembles  the  blade  of  a 
pen-knife  slightly  serrated :  they  appear  as  if  eroded  by  worms,  whence  the  name  of 
the  genus.  The  thorax  is  transversely  channelled ;  and  the  elytra  are  extremely  sca- 
brous at  the  base. 
Scolecobrotus  Westm^oodii. 
Tab.  XV.  Fig.  5. 
Scol.  jlavo-ferrugineus ;  elytris  ad  basin  punctulatis,  ad  apicem  bidentatis. 
Long,  corporis  14  lin.  ;  lat.  3. 
Hab.  in  Nova  HoUandia. 
Mus.  Hope. 
Descr.  Antennae  ferruginese,  articulis  prioribus  tribus  glabris,  cseteris  serrato-dentatis 
dente  apicali  in  singulis  fortiore,  externo  breviore  subserrato.  Caput  oblongius- 
culura,  antice  rubrum,  linea  longitudinali  inter  oculos  impressa,  pilis  flaveohs 
obsitum.  Thorax  tubercuhs  duobus  fere  mediis  ornatus,  rugisque  transversis 
balteatus.  Elytra  ad  basin  punctatissima,  postice  flavo-pilosa,  2-dentata.  Corpus 
infra  unicolor.    Pedes  supra  rubescentes,  subtus  flavo-pubescentes. 
I  have  much  pleasure  in  naming  this  singular  species  in  honour  of  J.  O,  West- 
wood,  Esq.,  whose  tact  in  dissecting  and  delineating  insects  is  not  surpassed  by  any 
entomologist,  either  British  or  foreign.
