108  THE  REV.  F.  W.  HOPE'S  CHARACTERS  AND  DESCRIPTIONS  OF 
family  will  admit  of  yet  more  subdivisions.  Stenocorus  discoideus,  Sturm,  for  instance, 
with  Sten.  rufipes,  Klug,  both  from  Mexico,  must  at  some  future  time  be  formed  into 
a  subgenus. 
Of  the  new  genera  and  species  indicated  in  the  preceding  table,  I  propose  at  present 
to  illustrate  but  two.  The  illustration  of  the  others  would  amply  repay  any  one  for  the 
time  and  patience  which  he  might  devote  to  their  attentive  investigation ;  and  I  should 
be  happy  to  aid  him  in  such  an  undertaking.  All  the  insects  referred  to  are  con- 
tained in  my  collection,  on  which  the  table  is,  in  fact,  entirely  founded.
