  (Prionidus) 
  The 
  "wheel-bug." 
  Occurs 
  throughout 
  the 
  

   State, 
  but 
  more 
  commonly 
  in 
  the 
  southern 
  sections. 
  It 
  is 
  the 
  largest 
  

   species 
  of 
  the 
  family 
  and 
  conspicuous 
  by 
  its 
  toothed 
  thoracic 
  crest, 
  

   which 
  looks 
  from 
  the 
  side 
  like 
  the 
  segment 
  of 
  a 
  cog-wheel. 
  The 
  egg- 
  

   masses 
  are 
  frequently 
  found 
  on 
  fruit 
  trees, 
  but 
  the 
  insects 
  are 
  bene- 
  

   ficial 
  rather 
  than 
  harmful. 
  They 
  feed 
  on 
  all 
  sorts 
  of 
  slugs 
  and 
  cater- 
  

   pillars, 
  and 
  according 
  to 
  Mr. 
  Davis, 
  also 
  take 
  grasshoppers 
  and 
  

   bumble-bees.
