Thorax and elytra always acutely and sometimes Ijroadly mar- 

 gined, margin more or less reflexed. 



The epipleura> always narrow,' rarely defined from the inflexed 

 sides of the elytra, except at apex, where they are always well defined, 

 not suddenly Avidened at base and never attaining the humeral angles 

 of the elytra. 



The above characters are distinctive of the genus and are not 

 observed elscAvhere in the Eleodiini. 



The constriction of the protibise at base is not peculiar to Emlxi- 

 phio7i, for it is also observed in BlafyVix^ and to a less degree in 

 IJiscogenia. 



The inentum presents no dis(incti\e characters; it is as variable here 

 as elsewhere. The middle lobe is somewhat larger than in the true 

 Eleodes, slightly smaller than in Discogenia; although the latei-a! 

 lobes are not so strongly exident as in Elcodcs, they are larger than 

 in the subgenus D'tscogchui. 



The abdominal and metasternal processes are moderate and (juite 

 equal in width in the present genus, and this is also occasionally 

 observed in Ehodex (fiisifomils nnd opdcct). 



The profemora are always nuUic; the tibial s|)urs are (juite similai' 

 in the sexes. The anterior spurs of the protibije are never noticeably
