OXYPYGIDES, new genus. 



Differing from Oxypge in having a prominent ridge on corner 

 of second tergite below and a deep and characteristic pit caudad of 

 the mesal end of this ridge ; also in having the anal tergite rounded 

 behind instead of acute, this exceeded by the anal valves. Processes 

 of anal valves remote from edge of tergite instead of in contact with 

 it. The anterior impressions of the scobina are wide in all the known 

 species.
