At one extreme of development of the color pattern, each elytron bears two large discal spots and four smaller spots laterally; often the discal spots are confluent at the suture.
At the other extreme, the discal spots of each elytron are broadly confluent, thus forming a broad vitta; sometimes these vittae meet at the suture, usually they do not.
Those specimens bearing broad vittae have three or four lateral spots. (2)
