106  THE  REV.  F.  W.  HOPE'S  CHARACTERS  AND  DESCRIPTIONS  OF 
duabus  rotundatis  dorsalibus.  Scutellum  postice  rotundatum,  punctatum.  Elytra 
coriacea,  varioloso-tuberculata,  lineis  tribus  longitudinalibus  vix  distinctis.  Corpus 
inM  piceum.    Pedes  atri. 
This  insect  was  obtained  at  Concep9ion  and  Valparaiso,  on  the  trunks  of  trees,  by 
Mr.  H.  Cuming,  in  honour  of  whom  I  have  named  it.  The  success  of  his  indefatigable 
exertions  in  various  branches  of  Natural  History,  is  well  known  by  the  extensive  and 
interesting  collections  which  he  has  recently  brought  to  this  country. 
The  species  is  remarkable  for  the  form  of  its  armed  thorax ;  and  also  on  account  of 
the  under  surface  of  the  basal  joints  of  the  tarsi  being  smooth  and  cylindric,  and  en- 
tirely destitute  of  the  pulvination  which  exists  in  most  of  the  Prionidcs.  These  consi- 
derations induce  me  to  regard  it  as  the  type  of  a  subgenus,  to  which  the  name  of  Acan- 
thinodera^  may  be  applied.

Descr.  Antennee  nigrse,  corpus  longitudine  sequantes.  MandihulcB  incurvae,  acutissimse. 
Palpi  picei,  pilis  flavis  vestiti.  Caput  oblongum,  nigrum,  punctatum,  tubercuhs 
ad  antennarum  insertiones,  foveolaque  inter  oculos  posita.  Thorax  subquadratus, 
lateribus  in  spinas  duas  productis.  Scutellum  nigrum.  Elytra  rubro-castanea, 
nigro  marginata,  lineis  quibusdam  vix  distinctis.  Corpus  infra  nigro-piceum. 
Prosternum  inter  pedes  anticos  productum,  antic^  vald^  incisum,  postic^  atte- 
nuatum  et  infra  mesosternum  extensum ;  hoc  etiam  paullo  porrectum.  Femora 
antica  parum  incrassata,  picea.  Tihia  concolores,  ad  apicem  rufescentes.  Tarsi 
fermginei ;  anticorum  articulus  tertius  bilobus,  intermediorum  sub-bidentatus, 
posticorum  bifidus  bidentatus. 
I  have  named  this  insect  in  honor  of  Dr.  Maximilian  Perty ;  and  propose  for  it  the 
subgeneric  designation  of  Dissosternus^,  in  allusion  to  the  very  remarkable  structure  of 
the  sterna  of  its  prothorax  and  mesothorax. 
Fam.  STENOCORIDiE. 
Differing  from  the  greater  number  of  entomologists,  I  regard  the  genus  Stenocorus, 
'  'AKavdivos,  spinosus ;  Sepri,  collum.  ®  Liaaos,  duplex ;  trrepvoy,  sternum.
