This subfamily contaln-i many large showy insects : they are mostly ajiterous. and their 

 elytra are ufti-n elegantly markt«l with nutallir sjn.ts, or set off with »idendid melallir 

 hut«. 



The cnnibidc'!! run fiist, and are \ ery carnivon>us in their habits : hence they should be 

 preserve<l, as they are friendly to the farmer. Some of them discharge a p<jwerful odor 

 when taken, which is exhaled from a flui<i ejected fr"! •'■• ''-lonien, and remains a long 

 time. 



The Genus rARAnm, the tyi>icnl one of the family. O'lii.ims, according to Mr. Wett- 

 wooK, notwithstanding the n-strictions to which it ha.- Usn subjected, nearly '20U species. 

 By far the gn-alc-r number of thesi- siK!>cies are contlued t*) northern climes.
