The mandibles are destitute of the cavity filled with membrane 
on the inside as in 7rox, the membrane in fact being present, but 
extending along the inside of the jaws. The maxilleze also more 
nearly resemble those of Geotrupes than T'rox. The toothing of 
the tibiae is quite unlike either Zrox or Geotrupes, and resembles 
Cryptogenius, with which it also agrees in various other respects ; 
as the structure of the mandibles, the lateral carine of the elytra, 
colour, texture, sculpture, geographical distribution, &c.
