Throughout the State; scarce. April 17-Octol)er 31. Occurs 

 usually beneath stones on hillsides. One specimen, from Steuben

Tribe IL BRACHYGLUTINI. 



The differences between this and the preceding tribe are given 

 in the key. The palpi are less developed and the last joint is oval 

 or fusiform. The following genera are probably represented in the 

 State :
