The three species of Rhinocricus here described may be distinguished by the

dorsal blacker band ; dorsum of segments transversely striate, the transverse 



sulcus just traceable dorsally; anal valves as under (a'); legs pale 



cristovalensis. 



(b) Back without longitudinal bands and without transverse striae. 



("') Anal valves produced considerably beyond the tergite; body and 

 legs and antennae black, tergites not bisinuate posteriorly, scobina 

 small (jazellensis.
