PsELAPHiDAE. The Ant-loving Beetles 



They live beneath bark and stones and feed on minute 

 forms. When turning stones for them, do not hurry, for they 

 often ''play dead." Sifting dry trash in the winter is pro- 

 ductive and I have taken them by sweeping around swamps 

 at dusk in the autumn. They excrete a substance of which 

 ants are fond and so are tolerated and found in ants' nests.
