Sectio.  TETRAMERA,  Lat. 
(Rhynchophora,  Lat.) 
Fam.  Attelabid^,  Lat. 
Genus  Isacantha^ 
Rostrum  longum. 
Antennce  ante  rostri  medium  insertse,  versus  apicem  incrassatse,  haud  pecti- 
natae. 
Elytra  ad  basin  rotundata  paulloque  supra  thoracem  producta. 
Pedes  antici  maximi,  femoribus  dentibus  duobus  sequalibus  versus  apicem 
instructis. 
Antenna  ll-articulatse,  extrorsum  crassiores,  rostro  pauUo  ante  medium  insidentes, 
ar-ticulo  primo  longiusculo  subarcuato  extrorsum  crassiore,  secundo  brevi  obconico, 
tertio  quartoque  subsequalibus,  quinto  prioribus  duobus  breviore,  insequentibus 
quinque  magnitudine  crescentibus  obconicis  extrorsum  crassioribus,  ultimo  prae- 
cedenti  paullo  longiore  ad  apicem  conico.  Labrum  vix  distinctum.  Labium  antice 
productum,  ad  basin  transversa  dilatatum.  Mandibula  3-dentat3e,  dentibus  fere 
sequalibus.  Maxilla  apertae.  Palpi  brevissimi,  conici.  Mentum  subtransversum, 
quadratum. 
Thorax  pariim  convexus,  antici  angustior.  Corpus  elongatum,  postice  dilatatum,  alatum. 
Femora  antica  longiora,  reliquis  crassiora,  versus  apicem  2-spinosa.  Tibia  anticse 
ad  basin  subarcuatse.    Tarsi  pulvinati.    Ungues  simpiices. 
This  genus  appears  to  unite  Rhinotia,  Kirby,  with  Belus,  Schonh.  AU  the  three 
groups  are  from  New  Holland^. 
ISACANTHA  RHINOTIOIDES. 
Tab.  XIV.  Fig.  6. 
Is.  grisea  ;  elytris  punctatissimis. 
Long,  corporis  5-^  lin.,  rostro  incluso,  7  lin. ;  lat.  2. 
Hab.  in  Nova  HoUandia. 
Mus.  Hope. 
'  "Iffos,  aqualis;  uKuyda,  spina.    The  two  spines  on  each  of  the  anterior  femora  are  of  equal  size. 
*  To  another  nearly  allied  and  novel  genus,  lately  received  from  the  same  country,  I  have  given  the  name  of 
Pachyura  :  it  may  be  thus  briefly  characterized : — 
Isacantha  afliinis ;  antennis  extrorsum  crassioribus ;  rostro  deflexo ;  thorace  antice  angustiore ;  elytris  posticfe 
valde  dilatatis ;  pedibus  inermibus. 
The  species  on  vyhich  this  genus  is  founded  I  have  named  Pach.  Australis.
