XYNOPHRON RITSEMAE. 201 



position among the true Copridae, in which group it 

 again approaches the Pedaria by its quite similar trans- 

 verse coxae. On the other hand it diverges from this 

 genus by the very short apical spur of the posterior tibiae , 

 by which it closely approaches the Xynophron , from which 

 it is again distinguished by the more elongated and nar- 

 rower shape of the body , by the less compressed and 

 consequently less broad posterior tibiae, by the abdominal 

 sutures not having disappeared in the median line, and 

 finely by the thorax which is always rather considerably 

 inflated. 



The new genus again enlarges the group of those cu- 

 rious small Copridae from the East Indies , as Disphysema , 

 Parapliytus , Cassolus , Anoctus , Cyohius and Parachorius , 

 which all appear to be limited to a single species.
