 preceding together. Thorax transverse, widest at the level 

 of the middle and posterior thirds, the sides rounded and 

 narrowed anteriorly, less so behind, the posterior angles 

 rounded, the whole surface covered with fine, close, grannlar 

 sculpture, distinctly and finely pubescent. Elytra as long as 

 but slightly broader than the thorax, transverse, very similarly 

 sculptured to the thorax, finely pubescent. xA.bdomen gra-
