Tribe III. SAPKINI. 



The different g-enei-a of tViis tribe vary much in size aud form, 

 but all agree in lacking a lobe on the front of the prosteruum. The 

 memliers of the largest genus, Sapnniis, live mostly in carcasses, 

 especially tho.se of dea.d fish along the shores of i-ivers and lakes. 

 The others occur mostly beneath bark and st(ines. Six of thi> seven 

 genera are represented in the State.
