NEW  GENERA  AND  SPECIES  OF  COLEOPTEROUS  INSECTS.

Fab.,  as  a  family ;  and  compared  Vfiih  Lepturidee,  it  has  certainly  stronger  claims  to 
rank  as  such,  both  from  its  widely  extended  geographical  distribution,  and  the  numerous 
forms  included  in  it.  The  Lepturides  are  chiefly  confined  to  a  northern  latitude,  and  the 
metropolis  of  the  family  is  probably  North  America,  or  Northern  Europe.  There  are, 
it  is  true,  a  few  species  found  in  South  America ;  but  these  recede,  according  to  my 
views,  from  the  type  of  Lepturidce.  Stenocorus  affects  warmer  climates,  and  has  not 
yet,  I  believe,  been  found  in  Europe.  It  is  widely  dispersed  in  North  and  South 
America,  and  is  met  with  in  various  parts  of  the  Continent  of  India  and  in  Java,  as 
well  as  in  New  Holland.  The  following  table  will  give  a  concise  view  of  the  Stenoco- 
ridcB,  the  family  being  divided  in  the  first  instance  into  two  sections,  depending  on  the 
armature  of  the  antenncs.
