Ovate, broad, black, nitid, subconvex, and very finely and 

 closely punctured. Head with two very short transverse 

 stride on each side between the eyes, with a large yellow 

 spot in the middle, and two smaller and darker ones on the 

 vertex. Thorax very broad and short, somewhat rounded at the 

 base and very slightly bisinuated, and with the anterior angles 

 much advanced, and of a red colour. Elytra round and rather 

 depressed behind, with a thin yellow vitta extending from the 

 middle to the apex, near the lateral margin, and with one or two 

 minute spots of the same colour inside, and near the commence- 

 ment of the vitta. Under side of a nitid pitchy black, with a 

 yellow spot on the sides of each abdominal segment. The legs 

 are of a pitchy red.
