"The mature beetle in life rivals asparagi in beauty, but may be distinguished by its much broader elytra and its color. The ground color is orange red; each elytron is marked with six black dots, and the knees and a portion of the under surface of the thorax are also marked with black. The beetle, as it occurs on the plant when in fruit, very closely resembles at a little distance the ripening asparagus berry."—Government Printing Office, 1897
