ginato 4-setigero. Mentum maximum, cum jugulo aded connexum, ut 
vestigium nullum articuli videas, angulis basalibus 4-setosis, lateribus di- 
latatis, angulis anticis in lobos duos magnos obtusos productis, denteque 
medio obtuso abbreviato. Labium ultra apicem loborum menti produc-

articulis duobus terminalibus, subæqualibus, ultimo compresso apicem 
versus latiori, oblique truncato, subsecuriformi. Antenne gracillimze,

Sphallomorphá, lateribus magis rotundatis, et angulis posticis minüs acu-

Elytra obovata, quadrata, depressa, ad apicem obliqué subtruncata. Pedes 
breves. Femoribus ovato-compressis, tibiis tarsisque gracillimis simplici-
