 rounded, the hind angles quite indistinct; it is ratlier 

 ])aler in colour than the head and elytra, finely and not 

 closely ])unctured. The elytra are distinctly longer than 

 the thorax, but their ])unctuation is similar to it ; their 

 hind margin is not sinuate. Hind body Avith the basal 

 segments distinctly and not densely, the apical one 

 sparingly punctured; the three basal segments reddish, 

 the others darker. Legs }-ello\v.

 colour, finely punctured, without channel or impression. 

 Elytra broad, longer than the thorax ; black with a violet
