tatis, ultimo ovali. Mentum parvum, subquadratum, antice 

 parum latius. Labium fere rotundatum, disco elevato mi- 

 nor! rotundo. Palpi labiales breves tenues, 3-articulati, 

 articulis longitudine fere aequalibus, intermedio crassiori. 

 Prothorax transverso-quadratus, angulis acutis, lateribus

This beautiful insect in some respects approaches the genera

 nearly related to Hispa and its allies.
