 with its dorsal line yellow, a vitta on each side of it black, 

 and its sides pistacinous ; there is also a small yellow spot 

 near each posterior angle. Elytra black, each with four 

 yellow discal spots, one at the base extending for about a 

 third of the entire length of the elytra, and three others 

 between it and the apex, the two upper ones of a transverse 

 oval form, the one near the apex somewhat triangular ; 

 there is also a pistacinous vitta extending from the 

 base along the lateral margin for about a third of its entire 

 length. Underside and legs pistacinous, three apical 

 segments of the abdomen chesnut-brown, each with four
