TJ4 BIOLOGICAL SI'KVKY OF 



Staphylinidae 



The Rove or Short-winged Scavenger Beetles 

 They feed in decaying animal and vegetable matter upon 

 larvae of Hies, etc., and so are taken in meat traps. Ferment- 

 ing cantaloupe rind is a wonderful bait. Breaking up decay- 

 ing toadstools over a white bowl will give one many speeies 

 that are otherwise overlooked.
